The value of the maximum extending length is at most 20%, particularly preferably at most 10%, of the value of the maximum lateral range of the lateral sealing device. In particular, the central axis of the filling tube extends at least substantially parallel to the rotation axis and / or at least the principal extending axis of the substantially cylindrical containment area of ​​the lateral sealing device. Preferably, the filling station is positioned such that the vertical movement axis of the guide unit of the lateral sealing device intersects the filling station.

[0020] moreover 、 A vertical bag-making, filling, and sealing machine, and more particularly, a method for operating a vertical bag-making, filling, and sealing machine according to the present invention. The method involves moving at least two seal jaws of the transverse sealing device, particularly the aforementioned transverse sealing device, via the transverse sealing device, particularly the aforementioned moving unit, along the vertical movement axis of the transverse sealing device, particularly the aforementioned guide unit, and the transverse sealing device being at least substantially completely located within a substantially cylindrical containment area of ​​the guide unit, particularly partially defined by at least one of the aforementioned guide elements.The following is proposed.

In one process step, the substantial of the transverse sealing device can be rotated, preferably by the drive unit of the vertical bag-making, filling, and sealing machine, and / or manually by at least one mechanical control element, while sealing the packaging material and / or filling the package. Also, in one process step, at least substantial of the transverse sealing device can be rotated, preferably by the drive unit of the vertical bag-making, filling, and sealing machine, and / or manually by at least one mechanical control element, when the vertical bag-making, filling, and sealing machine is not filling the package and / or sealing the packaging material. Preferably, in one process step, at least substantial of the transverse sealing device is rotated over an angle of 90° about the axis of rotation of the transverse sealing device, relative to the machine frame. Alternatively, in a single process step, at least substantial of the lateral sealing device may be rotated about the axis of rotation of the lateral sealing device by angles different from 90° relative to the machine frame. In particular, in a single process step, the substantial of the lateral sealing device may be rotated steplessly about the axis of rotation from one working position of the lateral sealing device for sealing packaging material laterally to another working position of the lateral sealing device for sealing packaging material laterally. In particular, in a single process step, at least substantial of the lateral sealing device may be rotated about the axis of rotation of the lateral sealing device, which is fixed relative to the machine frame of the vertical bag-making, filling, and sealing machine, from one working position of the lateral sealing device for sealing packaging material laterally to another working position of the lateral sealing device for sealing packaging material laterally.Particularly preferably, in one process step, substantially the entire lateral sealing device is rotated around the rotation axis of the lateral sealing device, particularly by the drive unit of the vertical bag-making, filling, and sealing machine and / or manually by at least one mechanical control element, from one working position to another without translational movement of the lateral sealing device relative to the machine frame.

The filling station 24a, the supply station, the lateral sealing device 14a, and / or the longitudinal sealing device are mounted on the machine frame 12a of the vertical bag-making, filling, and sealing machine 10a.

[0025] The lateral sealing device 14a is mounted on the machine frame 12a such that at least substantially the entire lateral sealing device 14a is rotatable about the rotation axis 16a of the lateral sealing device 14a. At least substantially all components of the lateral sealing device 14a are simultaneously rotatable about the rotation axis 16a of the lateral sealing device 14a, particularly relative to the machine frame 12a. The lateral sealing device 14a includes a frame 70a. All components of the lateral sealing device 14a other than the frame 70a are mounted on the frame 70a of the lateral sealing device 14a. The frame 70a of the lateral sealing device 14a is movably, preferably rotatably, positioned on the machine frame 12a.

[0026] The lateral sealing device 14a is mounted to the machine frame 12a so that its axis of rotation 16a is fixed relative to the machine frame 12a, and in particular so that it is not affected by the operational movement of the lateral sealing device 14a relative to the machine frame 12a. The lateral sealing device 14a is mounted to the machine frame 12a such that at least substantially the entire lateral sealing device 14a is movable only by the rotation of substantially the entire lateral sealing device 14a about its axis of rotation 16a. The rotation of substantially the entire lateral sealing device 14a relative to the machine frame 12a can occur without at least substantially the translational movement of the lateral sealing device 14a relative to the machine frame 12a. The lateral sealing device 14a is mounted to the machine frame 12a such that substantially the entire lateral sealing device 14a has only one degree of freedom of movement. Alternatively, the lateral sealing device 14a may be mounted on the machine frame 12a such that it is capable of translational movement, particularly relative to the machine frame 12a, and particularly along a direction parallel to the translational movement axis of the guide unit 82a of the lateral sealing device 14a. The rotation axis 16a of the lateral sealing device 14a extends at least substantially perpendicular to the support surface of the machine frame 12a. The support surface of the machine frame 12a is configured to transfer the weight of the vertical bag-making, filling, and sealing machine 10a, particularly the machine frame 12a, to the floor on which the vertical bag-making, filling, and sealing machine 10a is located.

The lateral sealing device 14a is mounted to the machine frame 12a such that the lateral sealing device 14a is positionable to at least two working positions for sealing packaging material laterally, particularly without translational movement of the lateral sealing device 14a relative to the machine frame 12a. The lateral sealing device 14a is positionable to at least two working positions for sealing packaging material laterally, solely by rotation of the lateral sealing device 14a relative to the machine frame 12a, without additional, particularly linearly guided, movement of the lateral sealing device 14a relative to the machine frame 12a. The at least two working positions of the lateral sealing device 14a differ in their rotational positions relative to the machine frame 12a, in particular. The at least two working positions of the lateral sealing device 14a differ from each other by an angle of 90°. Alternatively, the at least two working positions of the lateral sealing device 14a may differ from each other by an angle less than 90°, preferably by an angle greater than 0° and less than 360°. It is also possible that the lateral sealing device 14a is rotatable more than 360° relative to the machine frame 12a, particularly by integer or non-integer multiples of 360°.The energy supply line of the vertical bag-making, filling, and sealing machine 10a for supplying energy to the lateral sealing device 14a may be configured and / or positioned relative to the machine frame 12a and / or the lateral sealing device 14a so as to enable 360° rotation of the lateral sealing device 14a relative to the machine frame 12a, preferably rotation greater than 360°, particularly rotation by integer or non-integer multiples of 360°. Exemplarily, the energy supply line is positioned in combination with a slip ring, rotary transformer, or similar of the vertical bag-making, filling, and sealing machine 10a so as to enable 360° rotation of the lateral sealing device 14a relative to the machine frame 12a. At least substantially the entire lateral sealing device 14a may be infinitely rotatable around the rotation axis 16a to each different working position for sealing the packaging material laterally. Alternatively, at least substantially the entire lateral sealing device 14a may be rotatable about the rotation axis 16a of the lateral sealing device 14a, particularly to spaced rotational positions relative to the machine frame 12a, forming different working positions for the lateral sealing device 14a.

[0028] Figure 2 shows a schematic structure of a transverse sealing device that differs at least partially from the actual configuration of the transverse sealing device 14a shown in Figure 3. However, Figure 2 shows the interaction between the guide unit 32a of the vertical bag-making, filling, and sealing machine 10a and the transverse sealing device 14a. The guide unit 32a of the vertical bag-making, filling, and sealing machine 10a is intended to guide the rotation of the transverse sealing device 14a at least substantially as a whole around the rotation axis 16a. The guide unit 32a of the vertical bag-making, filling, and sealing machine 10a comprises at least one guide element 124a. This at least one guide element 124a at least partially defines at least substantially cylindrical containment area 126a in which the transverse sealing device 14a is at least substantially entirely contained.

The at least one additional guide element 134a may be integrated with the lateral sealing device 14a. Alternatively, at least one additional guide element 134a of the guide unit 32a of the vertical bag-making, filling, and sealing machine 10a may be positioned detachably, particularly non-destructively, to the lateral sealing device 14a.

[0032] The guide unit 32a and / or machine frame 12a of the vertical bag-making, filling, and sealing machine 10a may have one or more support points. At these support points, the lateral sealing device 14a, particularly the frame 70a of the lateral sealing device 14a, is movably connected to the guide unit 32a and / or machine frame 12a of the vertical bag-making, filling, and sealing machine 10a. At least one support point is located below or above the lateral sealing device 14a, preferably on at least one projection 128a of the guide element 124a, when viewed at least in a direction parallel to the rotation axis 16a.

[0033] The cylindrical containment area 126a is at least partially defined by the inner wall 130a of the guide element 124a. The projection 128a of the guide element 124a protrudes into the cylindrical containment area 126a.

The at least substantially cylindrical containment area 126a is surrounded by at least 75°, preferably at least 90°, along the circumferential direction of this at least substantially cylindrical containment area 126a by at least one guide element 124a, in particular the inner wall 130a of this guide element 124a. The circumferential direction of the at least substantially cylindrical containment area 126a extends in a plane that is at least substantially perpendicular to the main extending axis 136a of the cylindrical containment area 126a. In this specification, the “principal extending axis” of an object or region means, in particular, an axis that extends parallel to the longest side of the smallest geometric rectangular prism that completely encloses the object or region. Alternatively, the at least substantially cylindrical containment region 126a may be surrounded by at least one guide element 124a, in particular by the inner wall 130a of the guide element 124a, for at least 135°, preferably at least 180°, along the circumferential direction of the at least substantially cylindrical containment region 126a.

The rotation axis 16a is located in the sealing planes 22a of at least two sealing jaws 18a, 20a. The sealing plane 22a of at least two seal jaws 18a, 20a is defined in particular by the sealing surfaces 76a of at least two seal jaws 18a, 20a, so that the sealing surfaces 76a of at least two seal jaws 18a, 20a are directly adjacent to each other, preferably in contact with each other. The proximal region of the sealing plane 22a has a maximum extending length originating from the sealing plane 22a. This maximum extending length is oriented particularly perpendicular to the sealing plane 22a. The value of the maximum extending length is at most 20%, particularly preferably at most 10%, of the value of the maximum lateral range of the lateral sealing device 14a. The main extending axis 136a of at least a substantially cylindrical housing region 124a is located within the sealing plane 22a of at least two seal jaws 18a, 20a.

[0037] The guide element 124a of the guide unit 32a of the vertical bag-making, filling, and sealing machine 10a defines a circular guide path 140a. In this case, the lateral sealing device 14a is at least substantially entirely located inside the cylinder 142a corresponding to the circular guide path 140a. The cylinder 142a corresponding to the circular guide path 140a differs from the cylindrical containment area 126a, particularly with respect to its radius. The circular guide path 140a is defined by the guide groove 132a of the guide element 124a. Alternatively, the cylinder 142a corresponding to the circular guide path 140a may be equal to the cylindrical containment area 126a. In particular, alternatively, the cylindrical containment area 126a may be at least partially defined by the circular guide path 140a of the guide element 124a.

The guide unit 82a of the lateral sealing device 14a includes two additional guide elements 84a for guiding at least two seal jaws 18a and 20a during their relative horizontal movement. The two additional guide elements 84a of the guide unit 82a of the lateral sealing device 14a are implemented in a different form from the two guide elements 64a and 74a of the guide unit 82a. The two additional guide elements 84a of the guide unit 82a of the lateral sealing device 14a are configured in particular as guide rods or similar that are non-rotatably positioned relative to the frame 70a.

[0043] The lateral sealing device 14a includes at least one moving unit 36a for moving at least two seal jaws 18a, 20a relative to each other, particularly in translation, along a direction parallel to the horizontal movement axis 38a of the guide unit 82a of the lateral sealing device 14a, and / or for moving at least two seal jaws 18a, 20a relative to each other, particularly in translation, along a direction parallel to the vertical movement axis 40a of the guide unit 82a of the lateral sealing device 14a. The lateral sealing device 14a preferably includes at least two drive units 42a, 44a for providing driving forces to generate horizontal and / or vertical movement of at least two seal jaws 18a, 20a relative to the frame 70a and / or machine frame 12a. One of the at least two drive units 42a, 44a, drive unit 44a, is configured to drive the moving unit 36a to generate horizontal movement of at least two seal jaws 18a, 20a relative to each other. At least one of the two drive units 42a, 44a, another drive unit 42a is configured to drive the moving unit 36a to generate vertical movement of at least two seal jaws 18a, 20a.

The other drive unit 42a of the two drive units 42a, 44a includes a lifting fork, transmission belt, gears or similar for transmitting the driving force of at least one of the other drive units 42a to the at least two seal jaws 18a, 20a, in particular to generate vertical movement of the at least two seal jaws 18a, 20a relative to the frame 70a. Alternatively, another drive unit 42a may be configured to drive the moving unit 36a to generate vertical movement of at least two seal jaws 18a, 20a, in particular, relative to the frame 70a.The horizontal movement axes of at least two relative seal jaws 18a, 20a extend along a direction parallel to the horizontal movement axis 38a of the guide unit 82a of the lateral sealing device 14a. The vertical movement of at least two seal jaws 18a, 20a extends along a direction parallel to the vertical movement axis 40a of the guide unit 82a of the lateral sealing device 14a.

The drive unit 44a and the other drive unit 42a of the lateral sealing device 14a are positioned at least substantially fixed relative to the machine frame 12a. In particular, the statement that the drive unit is positioned "at least substantially fixed in place" means that there is no movement other than the movement of the mechanical components of the drive unit that inevitably move during the operation of the drive unit.

[0044] The horizontal movement axis 38a of the guide unit 82a of the lateral sealing device 14a extends at least substantially perpendicular to the rotation axis 16a of the lateral sealing device 14a. The term “substantially perpendicular” means, in this specification, the orientation of the direction in particular relative to the reference direction. In this case, the direction and the reference direction include an angle of 90°, particularly when viewed in the projection plane, and the angle has a maximum deviation of less than 8°, favorably less than 5°, and particularly favorably less than 2°. The vertical movement axis 40a of the guide unit 82a of the lateral sealing device 14a extends at least substantially parallel to the rotation axis 16a of the lateral sealing device 14a. The term “substantially parallel” means, in this specification, the orientation of the direction in particular relative to the reference direction, particularly in the plane. In this case, the direction has a deviation from the reference direction of less than 8°, favorably less than 5°, and particularly favorably less than 2°. At least two seal jaws 18a, 20a are configured to seal packaging material that can be placed between these at least two seal jaws 18a, 20a.

The rotation axis 16a of the lateral sealing device 14a extends at least substantially parallel to the sealing surfaces 76a of the at least two seal jaws 18a, 20a.

[0045] The moving unit 36a is positioned at least substantially completely laterally relative to at least two seal jaws 18a, 20a when viewed in a direction parallel to the horizontal movement axis 38a of the guide unit 82a of the lateral sealing device 14a. The fact that one object is positioned at least substantially completely laterally relative to another object means, as used herein, that at least 50%, preferably 75%, and especially preferably at least 90% of the total volume and / or total mass of the object is positioned laterally relative to another object. Preferably, in at least one operating state of the moving unit, the moving unit is positioned completely laterally relative to at least two seal jaws when viewed in a direction parallel to the horizontal movement axis. The moving unit 36a is realized in a different form from the drive unit 44a and / or another drive unit 42a. The moving unit 36a is realized in a different form from the guide unit 82a of the lateral sealing device 14a, and in a different form from at least the fixed-position guide elements of the lateral sealing device 14a. The guide unit 82a of the lateral sealing device 14a is preferably configured to guide the movement of at least two seal jaws 18a, 20a. The at least two seal jaws 18a, 20a are supported to move particularly linearly along a direction parallel to the horizontal movement axis 38a of the guide unit 82a of the lateral sealing device 14a. The at least two seal jaws 18a, 20a are supported to move particularly linearly along a direction parallel to the vertical movement axis 40a of the guide unit 82a of the lateral sealing device 14a.

[0046] The moving unit 36a is configured to convert forces that can be generated by the drive unit 44a and / or another drive unit 42a and act on at least two seal jaws 18a, 20a into horizontal movement of the at least two seal jaws 18a, 20a relative to each other and / or generate vertical movement of the at least two seal jaws 18a, 20a relative to the frame 70a and / or machine frame 12a in particular. The vertical movement axis 40a extends at least substantially parallel to the sealing surfaces 76a of the at least two seal jaws 18a, 20a and / or at least substantially perpendicular to the horizontal movement axis 38a.

[0047] The movable unit 36a is positioned laterally relative to the at least two seal jaws 18a, 20a such that the movable unit 36a is positioned at least substantially completely within the proximal region of the at least two seal jaws 18a, 20a. The fact that the movable unit 36a is positioned laterally relative to the at least two seal jaws 18a, 20a such that the movable unit 36a is positioned at least substantially completely within the proximal region of the at least two seal jaws 18a, 20a means, as herein it means, that the movable unit 36a is positioned laterally relative to the at least two seal jaws 18a, 20a such that at least 50%, preferably 75%, and particularly preferably at least 90% of the total volume and / or total mass of the movable unit 36a is positioned laterally relative to the at least two seal jaws 18a, 20a and within the proximal region of the at least two seal jaws 18a, 20a. In particular, the proximal regions of at least two seal jaws 18a, 20a extend beyond the at least two seal jaws 18a, 20a in a direction parallel to the horizontal movement axis 38a by a maximum of 20%, preferably a maximum of 10%, and especially preferably a maximum of 5% of the maximum movement range of the at least two seal jaws 18a, 20a. Preferably, the proximal regions of at least two seal jaws 18a, 20a extend beyond the at least two seal jaws 18a, 20a in a direction parallel to the vertical movement axis 38a by a maximum of 20%, preferably a maximum of 10%, and especially preferably a maximum of 5% of the maximum movement range of the at least two seal jaws 18a, 20a. Particularly preferably, the proximal regions of at least two seal jaws 18a, 20a extend beyond the at least two seal jaws 18a, 20a perpendicular to the vertical movement axis 40a and the horizontal movement axis 38a by a maximum of 20%, preferably a maximum of 10%, and particularly preferably a maximum of 5% of the maximum extending length of the at least two seal jaws 18a, 20a.

[0048] At least two seal jaws 18a, 20a are pullable to the sealed position by the moving unit 36a. At least two seal jaws 18a, 20a are movable to the sealed position relative to each other by the moving unit 36a without direct pressing movement of these at least two seal jaws 18a, 20a. At least two seal jaws 18a, 20a are pullable to the sealed position relative to each other along a direction parallel to the horizontal movement axis 38a by the moving unit 36a. The moving unit 36a is connected to the at least two seal jaws 18a, 20a such that the moving unit 36a generates a direct tensile force for pulling the at least two seal jaws 18a, 20a relative to each other to the sealed position. The moving unit 36a is connected to the at least two seal jaws 18a, 20a such that the at least two seal jaws 18a, 20a are moved synchronously relative to each other and, in particular, pulled. Alternatively, the moving unit 36a may be connected to at least two seal jaws 18a, 20a such that at least two seal jaws 18a, 20a are moved asynchronously relative to each other, and are particularly pulled.

[0049] The mobile unit 36a comprises four mobile elements 46a, 48a, 54a, and 56a, in particular, mechanical connecting elements. Exemplarily, the four mobile elements 46a, 48a, 54a, and 56a are configured as an arm. Alternatively, the four mobile elements 46a, 48a, 54a, and 56a may be configured as beams, support elements, gears, or similar. Alternatively, the mobile unit 36a may have only one mobile element or more than four mobile elements. The four mobile elements 46a, 48a, 54a, and 56a are configured identically to one another. Alternatively, the four mobile elements 46a, 48a, 54a, and 56a may be configured differently from one another. Two of the four movable elements 46a, 48a, 54a, and 56a are movably, and in particular rotatably, connected to at least one of the two seal jaws 18a and 20a.

[0050] Here, as an example, we will describe one of the four moving elements 46a, 48a, 54a, 56a, namely moving element 46a. This moving element 46a is directly, preferably movably, and particularly rotatably, connected to one of the at least two seal jaws 18a, 20a, namely seal jaw 18a. At least one other moving element 48a of the four moving elements 46a, 48a, 54a, 56a is directly, preferably movably, and particularly rotatably, connected to another seal jaw 20a of the at least two seal jaws 18a, 20a. Moving element 46a and the other moving element 48a are movable relative to each other. In this case, preferably, the relative movement of at least two seal jaws 18a, 20a can be achieved by the relative movement of moving element 46a and the other moving element 48a. The relative movement of moving element 46a and the other moving element 48a makes at least two seal jaws 18a, 20a pressable or tensible. The moving element 46a and the other moving element 48a are movable relative to each other to pull at least two seal jaws 18a, 20a toward a sealed position. The relative movement of the moving element 46a and the other moving element 48a to move at least two seal jaws 18a, 20a toward each other, in particular to a sealed position, can be achieved by rotational movement of the moving unit 36a, in particular by rotation of at least one additional moving element 86a of the moving unit 36a. Alternatively, the moving element 46a and the other moving element 48a may be movable relative to each other to move at least two seal jaws 18a, 20a toward each other by pressing and / or pulling movement of the moving unit 36a, in particular by pressing and / or pulling movement of the additional moving element 86a of the moving unit 36a.

[0051] The moving unit 36a comprises two torque-resisting linear bushings 62a, 68a. An additional moving element 86a is formed by one of the two torque-resisting linear bushings 62a, 68a. Alternatively, the moving unit 36a may comprise only one torque-resisting linear bushing 62a or more than two torque-resisting linear bushings. The at least two torque-resisting linear bushings 62a, 68a are configured to transmit drive torque, particularly from at least one drive unit 44a, to move at least two seal jaws 18a, 20a along a direction parallel to the horizontal axis 38a relative to each other. When viewed in a direction parallel to the horizontal movement axis 38a of the guide unit 82a of the lateral sealing device 14a, at least one torque-resisting linear bushing from the two torque-resisting linear bushings 62a, 68a is positioned on each side of at least two seal jaws 18a, 20a. At least when viewed perpendicular to the horizontal movement axis 38a and vertical movement axis 40a of the guide unit 82a of the lateral sealing device 14a, at least two torque-resisting linear bushings 62a, 68a are positioned on opposite sides of at least two seal jaws 18a, 20a, particularly laterally.

[0052] The moving element 46a and the other moving element 48a are movably, and in particular rotatably, connected to one of two torque-resisting linear bushings 62a, 68a, specifically to the torque-resisting linear bushing 62a. The torque-resisting linear bushing 62a, the moving element 46a, and the other moving element 48a are components of a crank slider mechanism 100a. This crank slider mechanism 100a is configured to transmit the driving force that can be generated by the drive unit 44a to the horizontal movement of at least two seal jaws 18a, 20a. The torque-resisting linear bushing 62a is configured to transmit the driving force, in particular from the drive unit 44a to the moving element 46a and the other moving element 48a, in order to move at least two seal jaws 18a, 20a relative to each other along a direction parallel to the horizontal movement axis 38a. The connection between two additional moving elements 54a, 56a of the four moving elements 46a, 48a, 54a, 56a, one additional moving element 88a of the moving unit 36a, and in particular one additional torque-resisting linear bushing 68a of the two torque-resisting linear bushings 62a, 68a, and the drive unit 44a is similar to the connection between moving element 46a, another moving element 48a, the additional moving element 86a, and in particular torque-resisting linear bushing 62a of the two torque-resisting linear bushings 62a, 68a, and the drive unit 44a.

[0053] The movable unit 36a, in particular at least one of the four movable elements 46a, 48a, 54a, 56a of the movable unit 36a, and the movable regions 60a of at least two seal jaws 18a, 20a, in particular at least partially overlap each other in at least one operating state of the at least two seal jaws 18a, 20a when viewed in a direction perpendicular to the horizontal movement axis 38a of the guide unit 82a of the lateral sealing device 14a. When viewed in a direction parallel to the horizontal movement axis 38a of the guide unit 82a of the lateral sealing device 14a, the rear and front regions of the at least two seal jaws 18a, 20a are at least substantially completely without the movable unit 36a.

[0054] Two torque-resisting linear bushings 62a, 68a are each movably, in particular linearly movably connected to one of the two guide elements 64a, 74a of the guide unit 82a of the lateral sealing device 14a. At least one drive unit 44a is configured to drive at least two guide elements 64a, 74a of the guide unit 82a of the lateral sealing device 14a to rotate at least two guide elements 64a, 74a of the guide unit 82a of the lateral sealing device 14a about the axis of rotation 66a to generate the horizontal movement of two seal jaws 18a, 20a relative to each other. The moving unit 36a is formed by the two torque-resisting linear bushings 62a, 68a, the two guide elements 64a, 74a of the guide unit 82a of the lateral sealing device 14a, and four moving elements 46a, 48a, 54a, 56a. Alternatively, the moving unit 36a may be formed in a different form, particularly as deemed appropriate by those skilled in the art. Two torque-resisting linear bushings 62a, 68a are each connected to one of two guide elements 64a, 74a of the guide unit 82a of the lateral sealing device 14a in a relative-rotation-immobile manner. At least two guide elements 64a, 74a of the guide unit 82a of the lateral sealing device 14a are positioned at least substantially completely laterally relative to at least two seal jaws 18a, 20a when viewed in a direction parallel to the horizontal movement axis 38a of the guide unit 82a of the lateral sealing device 14a. The main extending axes of at least two guide elements 64a, 74a of the guide unit 82a of the lateral sealing device 14a are at least substantially perpendicular to the horizontal movement axis 38a of the guide unit 82a of the lateral sealing device 14a. The main extending axes of at least two guide elements 64a, 74a of the guide unit 82a of the lateral sealing device 14a are at least substantially parallel to the vertical movement axis 40a of the guide unit 82a of the lateral sealing device 14a. The main extending axes of the two guide elements 64a, 74a of the guide unit 82a of the lateral sealing device 14a correspond to their rotation axis 66a.The two guide elements 64a and 74a of the guide unit 82a of the lateral sealing device 14a are capable of receiving the driving force from the drive unit 44a by a transmission belt, gear, or similar mechanism of the drive unit. The two guide elements 64a and 74a of the guide unit 82a of the lateral sealing device 14a form two additional moving elements 90a of the moving unit 36a. The guide elements 64a and 74a of the guide unit 82a of the lateral sealing device 14a are rotatably connected to the frame 70a of the lateral sealing device 70a.

[0055] Two torque-resisting linear bushings 62a, 68a may be moved along two guide elements 64a, 74a of the guide unit 82a of the lateral sealing device 14a, respectively, for the vertical movement of at least two seal jaws 18a, 20a. The vertical movement of at least two seal jaws 18a, 20a is directly linked to the vertical movement of the two torque-resisting linear bushings 62a, 68a. At least one additional drive unit 42a is configured to drive a movement unit 36c to generate the vertical movement of at least two seal jaws 18a, 20a relative to the frame 70a.

[0056] Figure 4 schematically shows a flowchart of how to operate the vertical bag-making, filling, and sealing machine 10a. In process step 34a, at least substantially the entire transverse sealing device 14a of the vertical bag-making, filling, and sealing machine 10a is rotated about the rotation axis 16a of the transverse sealing device 14a relative to the mechanical frame 12a of the vertical bag-making, filling, and sealing machine 10a. In process step 34a, substantially the entire transverse sealing device 14a can be rotated, preferably by the drive unit 30a of the vertical bag-making, filling, and sealing machine 10a and / or manually by at least one mechanical control element, while sealing the packaging material and / or filling the package. Furthermore, in process step 34a, while the vertical bag-making, filling, and sealing machine 10a is not filling the packages and / or sealing the packaging material, at least substantially the entire transverse sealing device 14a may be rotated, preferably by the drive unit 30a of the vertical bag-making, filling, and sealing machine 10a, and / or manually by at least one mechanical control element. Preferably, in process step 34a, at least substantially the entire transverse sealing device 14a is rotated by an angle of 90° around the axis of rotation 16a of the transverse sealing device 14a relative to the machine frame 12a. Alternatively, in process step 34a, at least substantially the entire transverse sealing device 14a may be rotated by an angle different from 90° relative to the machine frame 12a, around the axis of rotation 16a of the transverse sealing device 14a.

[0057] In process step 34a, substantially the entire lateral sealing device 14a is rotated steplessly around the axis of rotation 16a from one working position of the lateral sealing device 14a for sealing packaging material laterally to another working position of the lateral sealing device 14a for sealing packaging material laterally. In process step 34a, at least substantially the entire lateral sealing device 14a is rotated around the axis of rotation 16a, which is fixed relative to the machine frame 12a of the vertical bag-making, filling, and sealing machine 10a, from one working position of the lateral sealing device 14a for sealing packaging material laterally to another working position of the lateral sealing device 14a for sealing packaging material laterally. Particularly preferably, in process step 34a, substantially the entire lateral sealing device 14a is rotated around the rotation axis 16a of the lateral sealing device 14a, in particular by the drive unit 30a of the vertical bag-making, filling, and sealing machine 10a and / or manually by at least one mechanical control element, from one working position to another without translational movement of the lateral sealing device 14a relative to the machine frame 12a.

[0058] In the subsequent process step 80a, at least two seal jaws 18a, 20a are moved to a sealing position for sealing the packaging material laterally. It is also possible that at least two seal jaws 18a, 20a are moved to a sealing position for sealing the packaging material laterally in process step 34, particularly during the rotation of the lateral sealing device 14a around the rotation axis 16a of the lateral sealing device 14a relative to the machine frame 12a.

[0059] Figure 5 schematically shows a flowchart of how to operate a lateral sealing device 14a for sealing a package or packaging material. In process step 72a, at least two seal jaws 18a, 20a of the lateral sealing device 14a are pulled to the sealing position by the moving unit 36a of the lateral sealing device 14a. In process step 72a, at least moving element 46a and at least one other moving element 48a of the two moving elements 46a, 48a of the moving unit 36a are moved relative to each other by the drive unit 44a to generate a tensile force that pulls at least two seal jaws 18a, 20a toward each other to the sealing position. In process step 72a, the driving force for moving at least two seal jaws 18a, 20a relative to each other along a direction parallel to the horizontal movement axis 38a is transmitted by two torque-resisting linear bushings 62a, 68a of the moving unit 36a. In process step 72a, the drive unit 44a drives the guide elements 64a and 74a of the guide unit 82a of the lateral sealing device 14a to rotate about their axis of rotation 66a in order to generate rotation of the two torque-resisting linear bushings 62a and 68a. In process step 72a, the rotational force of the torque-resisting linear bushing 62a of the two torque-resisting linear bushings 62a and 68a is converted into relative movement between moving element 46a and another moving element 48a in order to generate a tensile or compressive force to move at least two seal jaws 18a and 20a relative to each other along a direction parallel to the horizontal movement axis 38a of the guide unit 82a of the lateral sealing device 14a. This is similar to the other torque-resisting linear bushing 68a of the two torque-resisting linear bushings 62a and 68a and two other moving elements 54a and 56a. In the subsequent process step 80a, at least two seal jaws 18a, 20a are moved vertically relative to the frame 70a by another drive unit 42a.

[0061] Figure 6 shows a lateral sealing device 14b for sealing a package or packaging material. This lateral sealing device 14b comprises at least two sealing jaws 18b, 20b. The lateral sealing device 14b comprises at least one moving unit 36b for translating the at least two sealing jaws 18b, 20b relative to each other along a direction parallel to the horizontal movement axis 38b of the guide unit 82b of the lateral sealing device 14b, and for translating the at least two sealing jaws 18b, 20b along a direction parallel to the vertical movement axis 40b of the guide unit 82b of the lateral sealing device 14b, in particular relative to the frame (not shown) of the lateral sealing device 14b. This moving unit 36b comprises two ball screw slide mechanisms 116b located on opposite sides of the at least two sealing jaws 18b, 20b. These two ball screw slide mechanisms 116b can convert the driving force of at least one drive unit (not shown) of the lateral sealing device 14b into horizontal and vertical movement of at least two seal jaws 18b, 20b, in particular, relative to the frame. The moving unit 36b is positioned at least substantially completely laterally relative to the at least two seal jaws 18b, 20b when viewed in a direction parallel to the horizontal movement axis 38b of the guide unit 82b of the lateral sealing device 14b. The moving unit 36b is positioned at least substantially completely within the proximal region of the at least two seal jaws 18b, 20b when viewed in a direction parallel to the horizontal movement axis 38b of the guide unit 82b of the lateral sealing device 14b. The at least two seal jaws 18b, 20b are tensible to the sealed position by the moving unit 36b.

[0062] Figure 7 shows a lateral sealing device 14c for sealing a package or packaging material. This lateral sealing device 14c comprises at least two sealing jaws 18c, 20c. The lateral sealing device 14c comprises at least one moving unit 36c for translating the at least two sealing jaws 18c, 20c relative to each other along a direction parallel to the horizontal movement axis 38c of the guide unit 82c of the lateral sealing device 14c, and for translating the at least two sealing jaws 18c, 20c along a direction parallel to the vertical movement axis 40c of the guide unit 82c of the lateral sealing device 14c, in particular relative to the frame (not shown) of the lateral sealing device 14c. The lateral sealing device 14c comprises at least two drive units 42c, 44c for driving the moving unit 36c.

[0063] At least two drive units 42c, 44c are connected to each other by the moving unit 36c such that horizontal and / or vertical movement of at least two seal jaws 18c, 20c can be generated by joint driving of the moving unit 36c by at least two drive units 42c, 44c. Horizontal and / or vertical movement of at least two seal jaws 18c, 20c can only be generated by driving performed by all of the at least two drive units 42c, 44c. When at least one of the at least two drive units 42c, 44c is in a resting state, movement of the moving unit 36c, in particular movement other than vibration movement which may occur when the moving unit 36c is driven by just one of the at least two drive units 42c, 44c to generate horizontal and / or vertical movement of at least two seal jaws 18c, 20c, is prevented. If the moving unit 36c is not driven by at least one of the two drive units 42c, 44c, the movement of the moving unit 36c is prevented from generating the horizontal and / or vertical movement of at least two seal jaws 18c, 20c.

[0064] The movable unit 36c can be driven by joint drive by at least two drive units 42c, 44c so as to cause only horizontal movement of at least two seal jaws 18c, 20c relative to the frame (not shown) of the lateral sealing device 14c. The movable unit 36c can be driven by joint drive by at least two drive units 18c, 20c so as to cause only vertical movement of at least two seal jaws 18c, 20c relative to the frame of the lateral sealing device 14c. It is also possible for the movable unit 36c to be driven by joint drive by at least two drive units 42c, 44c so as to cause both horizontal and vertical movement of at least two seal jaws 18c, 20c relative to the frame of the lateral sealing device 14c simultaneously.

[0065] The moving unit 36c comprises two moving elements 46c, 48c to form a movable connection between two drive units 42c, 44c and at least two seal jaws 18c, 20c. These two moving elements 46c, 48c are configured as arms. Alternatively, the two moving elements 46c, 48c may be configured as beams, support elements, in particular torque-resisting linear bushings, gears, or similar. The moving unit 36c comprises at least one drive connection element 94c for mechanically connecting at least two drive units 42c, 44c to each other. This drive connection element 94c is configured as a beam. Alternatively, the drive connection element 94c may be configured as an arm, support element, in particular torque-resisting linear bushings, gears, or similar. The drive connection element 94c is connected to at least two drive units 42c, 44c by the two moving elements 46c, 48c of the moving unit 36c. Alternatively, at least one of the at least two drive units 42c,44c may be directly, and particularly movably, connected to the drive connection element 94c, preferably without additional moving elements. The drive connection element 94c is preferably connected to at least two seal jaws 18c,20c via at least one additional moving element 96c of a move unit 36c that is connected to the drive connection element 94c in a relative non-rotatable manner. The move unit 36c comprises at least two slider elements 98c that are connected particularly movably, and particularly rotatably, to the additional moving element 94c and / or at least two seal jaws 18c,20c.

[0066] The drive connection element 94c, the two slider elements 98c, and the additional moving element 96c are components of the crank slider mechanism 100c, particularly positioned between at least two moving elements 46c, 48c and at least two seal jaws 18c, 20c. The two slider elements 98c are configured as arms. Alternatively, the two slider elements may be configured as beams, support elements, gears, or similar. The drive connection element 94c is preferably connected to the additional moving element 96c via a rod 102c or similar. Alternatively, the additional moving element 96c and the drive connection element 94c may be configured as an integral part of each other. The crank slider mechanism 100c is preferably configured to convert the driving force generated by at least two drive units 18c, 20c, particularly the movement of the drive connection element 94c, into horizontal and / or vertical movement of at least two seal jaws 18c, 20c. The drive connection element 94c is movable only by joint drive of at least two drive units 18c, 20c. In particular, in a preferred configuration of the present invention, the drive connection element may be driven to rotate about its rotation axis 104c by joint drive of at least two drive units 18c, 20c so as to generate horizontal movement of at least two seal jaws 18c, 20c. The rotation axis 104c of the drive connection element 94c extends at least substantially parallel to the sealing surfaces 76a of at least two seal jaws 18c, 20c. The rotation axis 104c of the drive connection element 94c extends at least substantially perpendicular to the horizontal movement axis 38c of the guide unit 82c of the lateral sealing device 14c and the vertical movement axis 40c of the guide unit 82c of the lateral sealing device 14c.

[0067] The moving unit 36c has a similar structure on both sides of at least two seal jaws 18c, 20c. The moving unit 36c includes another drive connection element 106c, which is configured identically to the drive connection element 94c. Alternatively, this other drive connection element 106c may be implemented in a different form from the drive connection element 94c. The drive connection element 94c and the other drive connection element 106c are located on opposite sides of at least two seal jaws 18c, 20c. The connection of the other drive connection element 106c to at least two seal jaws 18c, 20c is preferably similar to the connection of the drive connection element 94c to at least two seal jaws 18c, 20c. The connection of the other drive connection element 106c to at least two drive units 42c, 44c is similar to the connection of the drive connection element 94c to at least two drive units 42c, 44c. The moving unit 36c includes at least two other moving elements 54c, 56c. The connection of at least two additional moving elements 54c, 56c to at least two seal jaws 18c, 20c is analogous to the connection of at least two moving elements 46c, 48c to at least two seal jaws 18c, 20c. The connection of at least two additional moving elements 54c, 56c to another drive connection element 106c is analogous to the connection of at least two moving elements 46c, 48c to a drive connection element 94c. The connection of at least two additional moving elements 54c, 56c to at least two drive units 42c, 44c is analogous to the connection of at least two moving elements 46c, 48c to at least two drive units 42c, 44c. The at least two moving elements 46c, 48c and the at least two additional moving elements 54c, 56c are arranged on opposite sides of the at least two seal jaws 18c, 20c. At least two drive units 42c, 44c are positioned at least partially laterally to at least two seal jaws 18c, 20c when viewed in a direction at least parallel to the horizontal movement axis 38c.Alternatively, the two drive units 42c, 44c may be positioned centrally relative to at least two moving elements 46c, 48c and at least two other moving elements 54c, 56c when viewed in a direction parallel to the horizontal movement axis 38c of the guide unit 82c of the lateral sealing device 14c. Furthermore, alternatively, the at least two drive units 42c, 44c may be arranged in different configurations that a person skilled in the art would consider particularly appropriate. The moving unit 36c is composed of four moving elements 46c, 48c, 54c, 56c, in particular two moving elements 46c, 48c and two other moving elements 54c, 56c, two drive connection elements 94c, 106c, in particular drive connection element 94c and another drive connection element 106c, four slider elements 98c, of which two slider elements 98c are realized by at least two of the aforementioned slider elements 98c, two rods 102c, of which one rod is realized by the aforementioned rod 102c, and two additional moving elements 96c, of which one additional moving element is realized by the aforementioned additional moving element 96c. Alternatively, the moving unit 36c may consist only of one drive connection element, one rod, two moving elements, two slider elements, and one additional moving element. Furthermore, other embodiments of the moving unit 36c are possible that those skilled in the art would consider suitable. In particular, the moving unit 36c may be realized without the rod 102c.

[0068] Each of the at least two drive units 42c, 44c is provided with at least one drive shaft 108c. The driving direction of the drive units 42c, 44c corresponds to the rotational direction of the rotation of the drive shaft 108c around its rotational axis 110c. The rotational axis 110c of the drive shaft 108c corresponds to the principal extending axis of each drive shaft 108c. The rotational axis 110c of the drive shaft 108c of the at least two drive units 42c, 44c preferably extends at least substantially parallel to the sealing surfaces of at least two seal jaws 18c, 20c. The rotational axis 110c of the drive shaft 108c of the at least two drive units 42c, 44c extends at least substantially perpendicular to the horizontal movement axis 38c and vertical movement axis 40c of the guide unit 82c of the lateral sealing device 14c. The rotational axes 110c of the drive shafts 108c of at least two drive units 42c, 44c extend at least substantially parallel to each other. Alternatively, the rotational axes 110c of the drive shafts 108c of at least two drive units 42c, 44c may extend laterally relative to each other, preferably at least substantially perpendicular. The drive shaft 108c of one of the at least two drive units 42c, 44c is directly connected to one of two moving elements 46c, 48c and one of at least two other moving elements 54c, 56c. The drive shaft 108c of another drive unit 44c of the at least two drive units 42c, 44c is directly connected to another moving element 48c of at least two moving elements 46c, 48c and another moving element 54c of at least two other moving elements 54c, 56c.

[0069] The drive connection element 94c and the other drive connection element 106c may be driven by joint drive by at least two drive units 42c, 44c to translate along a direction parallel to the translation axis of the drive connection element 94c and the other drive connection element 106c, in particular to generate vertical movement of at least two seal jaws 42c, 44c relative to the frame of the lateral sealing device 14c. The translation axis of the drive connection element 94c and the other drive connection element 106c extends laterally with respect to the rotation axis 104c of the drive connection element 94c, and particularly preferably at least substantially perpendicularly. The translation axis preferably extends at least substantially parallel to the vertical movement axis 40c of the guide unit 82c of the lateral sealing device 14c and / or to the sealing surfaces of at least two seal jaws 18c, 20c. The translational movement axis extends at least substantially perpendicular to the horizontal movement axis 40c of the guide unit 82c of the lateral sealing device 14c.

[0070] The vertical movement of at least two seal jaws 18c, 20c can be achieved by parallel driving of the moving unit 36c by at least two drive units 42c, 44c. The vertical movement of at least two seal jaws 18c, 20c can be achieved by parallel driving of a drive connection element 94c and another drive connection element 106c by at least two drive units 42c, 44c. Parallel driving of a drive connection element 94c and another drive connection element 106c by at least two drive units 42c, 44c means that at least the direction and velocity of the movement transmitted to the drive connection element 94c and the other drive connection element 106c, which can be achieved by at least two drive units 42c, 44c, are matched to each other. The components of the crank slider mechanism 100c are simply translated as a whole via parallel driving of the moving unit 36c by at least two drive units 42c, 44c to generate vertical movement of at least two seal jaws 18c, 20c. The driving directions of at least two drive units 42c, 44c to generate parallel driving of the moving unit 36c, in particular between drive connection element 94c and another drive connection element 106c, are oriented in opposite directions to each other. Alternatively, the driving directions of at least two drive units 42c, 44c may coincide with each other to generate parallel driving of the moving unit 36c, in particular between drive connection element 94c and another drive connection element 106c. The absolute values ​​of the drive speeds of at least two drive units 42c, 44c can be matched or different from each other, preferably depending on the relative arrangement of the at least two drive units 42c, 44c and / or the arrangement of the moving unit 36c, in order to generate parallel drive between the moving unit 36c, particularly between the drive connection element 94c and another drive connection element 106c. The drive direction of the at least two drive units 42c, 44c depends on the relative arrangement of the at least two drive units 42c, 44c and / or the arrangement of the moving unit 36c.Alternatively, two drive units 42c, 44c may be arranged and / or configured such that parallel driving of the moving unit 36c can be generated by the synchronous operation of at least two drive units 42c, 44c. The moving unit 36c is arranged, in particular for the purpose of generating vertical movement of at least two seal jaws 18c, 20c relative to the frame of the lateral sealing device 14c, such that parallel driving of the moving unit 36c, in particular between drive connection element 94c and another drive connection element 106c generates translational movement of drive connection element 94c and another drive connection element 106c along a direction parallel to the translational movement axis of drive connection element 94c and another drive connection element 106c.

[0071] The horizontal movement of at least two relative seal jaws 18c, 20c can be generated by non-parallel driving of the moving unit 36c by at least two drive units 42c, 44c. Non-parallel driving of drive connection element 94c and another drive connection element 106c by at least two drive units 42c, 44c means that at least the directions of the movement transmitted to drive connection element 94c and another drive connection element 106c are different from each other, which can be generated by at least two drive units 42c, 44c. In particular, in the case of non-parallel driving of drive connection element 94c and another drive connection element 106c, which can be generated by at least two drive units 42c, 44c, the directions of the movement transmitted to drive connection element 94c and another drive connection element 106c are oriented in opposite directions from each other. The movement transmitted to the drive connecting element 94c and the other drive connecting element 106c by the non-parallel drive of the moving unit 36c by at least two drive units 42c, 44c, particularly the non-parallel drive of the drive connecting element 94c and the other drive connecting element 106c, is coordinated with each other, at least in terms of direction and velocity. The crank slider mechanism 100c is connected to at least two drive units 42c, 44c such that the crank slider mechanism 100c is configured to generate horizontal movement of at least two seal jaws 18c, 20c by the non-parallel drive of the moving unit 36c by at least two drive units 42c, 44c. In particular, the horizontal movement of at least two seal jaws 18c, 20c relative to the frame of the lateral sealing device 14c can be generated by the non-parallel drive of the drive connecting element 94c and the other drive connecting element 106c by at least two drive units 42c, 44c. Non-parallel driving of the moving unit 36c, particularly between the drive connection element 94c and another drive connection element 106c, can be made possible by the asynchronous operation of at least two drive units 42c, 44c. In this exemplary embodiment, the driving directions of at least two drive units 42c, 44c are aligned with each other to generate non-parallel driving of the moving unit 36c, preferably between the drive connection element 94c and another drive connection element 106c.The moving unit 36c is arranged such that the non-parallel drive of the moving unit 36c, in particular between the drive connection element 94c and the other drive connection element 106c, generates rotational movement between the drive connection element 94c and the other drive connection element 106c around the rotation axis 104c between them, in order to generate horizontal movement of at least two seal jaws 18c, 20c. The absolute values ​​of the drive speeds of at least two drive units 42c, 44c can be matched or different from each other, preferably depending on the relative arrangement of the at least two drive units 42c, 44c and / or the arrangement of the moving unit 36c, in order to generate parallel drive between the moving unit 36c, in particular between the drive connection element 94c and the other drive connection element 106c. Alternatively, the driving directions of at least two drive units 42c, 44c may be different from each other, preferably oriented in opposite directions, for the purpose of generating non-parallel driving of the moving unit 36c, in particular the drive connection element 94c and the other drive connection element 106c.

[0072] Two moving elements 46c, 48c are connected to each other movably, in particular rotatably. One of at least two drive units 42c, 44c, drive unit 42c, is mechanically connected to one of the at least two moving elements 46c, 48c, in order to drive the moving element 46c. Another drive unit 44c, one of the at least two drive units 42c, 44c, is mechanically connected to another moving element 48c, one of the at least two moving elements 46c, 48c, in order to drive the other moving element 48c. Two movable elements 46c, 48c and two other movable elements 54c, 56c are movably, and in particular rotatably, connected to one of the drive shafts 108c of at least two drive units 42c, 44c, respectively, via link arms 112c of at least two drive units 42c, 44c, which are positioned in a fixed position relative to each drive shaft 108c of the two drive units 42c, 44c.

[0073] The movable unit 36c is positioned at least substantially completely laterally relative to at least two seal jaws 18c, 20c when viewed in a direction parallel to the horizontal movement axis 38c of the guide unit 82c of the lateral sealing device 14c. The movable unit 36c is positioned at least substantially completely within the proximal region of at least two seal jaws 18c, 20c when viewed in a direction parallel to the horizontal movement axis 38c of the guide unit 82c of the lateral sealing device 14c. The at least two seal jaws 18c, 20c are tensible to the sealed position by the movable unit 36c.

[0074] Figure 8 schematically shows a flowchart of how the lateral sealing device is operated. In process step 58c, at least two seal jaws 18c, 20c of the lateral sealing device 14c are translated along a direction parallel to the horizontal movement axis 18c and / or vertical movement axis 40c of the guide unit 82c of the lateral sealing device 14c by joint driving of the moving unit 36c of the lateral sealing device 14c by at least two drive units 42c, 44c of the lateral sealing device 14c. The horizontal and / or vertical movement of at least two seal jaws 18c, 20c is generated by driving carried out by all of the at least two drive units 42c, 44c. In process step 58c, the forces generated by at least two drive units 42c, 44c are transmitted by the moving unit 36c to at least two seal jaws 18c, 20c to generate horizontal movement of at least two seal jaws 18c, 20c relative to each other and / or vertical movement of at least two seal jaws 18c, 20c relative to the frame of the lateral sealing device 14c. In process step 58c, the moving unit 36c can be driven by joint drive by at least two drive units 42c, 44c to generate only horizontal or vertical movement of at least two seal jaws 18c, 20c. In process step 58c, the drive connection element 94c and another drive connection element 106c are driven to rotate about the axis of rotation 104c between the drive connection element 94c and the other drive connection element 106c by joint drive by at least two drive units 42c and 44c, with the aim of generating horizontal movement of at least two seal jaws 18c and 20c. Alternatively, in process step 58c, the drive connection element 94c and the other drive connection element 106c may also be driven to rotate about the axis of rotation 104c between the drive connection element 94c and the other drive connection element 106c by joint drive by at least two drive units 42c and 44c, with the aim of generating vertical movement of at least two seal jaws 18c and 20c.In process step 58c, the drive connection element 94c and another drive connection element 106c are driven by joint drive by at least two drive units 42c, 44c to translate along a direction parallel to the translation axis of the drive connection element 94c and the other drive connection element 106c, with the aim of generating vertical movement of at least two seal jaws 18c, 20c. In process step 58c, the driving force generated by at least two drive units 42c, 44c, in particular the movement of the drive connection element 94c and the other drive connection element 106c, is converted by the crank slider mechanism 100c into horizontal and / or vertical movement of at least two seal jaws 18c, 20c.

[0075] In process step 58c, the moving unit 36c, in particular, at least two moving elements 46c, 48c of the moving unit 36c are driven in parallel by at least two drive units 42c, 44c to generate vertical movement of at least two seal jaws 18c, 20c. In process step 58c, the vertical movement of at least two seal jaws 18c, 20c is generated by parallel driving of a drive connection element 94c and another drive connection element 106c by at least two drive units 42c, 44c. In process step 58c, the moving unit 36c, in particular, at least two moving elements 46c, 48c of the moving unit 36c are driven in opposite directions by at least two drive units 42c, 44c to generate horizontal movement of at least two seal jaws 18c, 20c. In process step 58c, the horizontal movement of at least two seal jaws 18c,20c is generated by the non-parallel driving of drive connection element 94c and another drive connection element 106c by at least two drive units 42c,44c.
