Embodiment Construction

[0018] Refer below Figures 1 to 3 An apparatus 1 for producing packages from a web of packaging material is described in detail. Such a device 1 is also referred to as a tube bag machine, in which first a plastic tube is formed from the packaging material web, and the packaging is then produced from the plastic tube. In this example a vertical hose bag machine is shown.

[0019] like figure 1 As shown, the device 1 comprises a forming tube 2 on which a forming shoulder 3 is arranged. There is also a filling tube 11 extending in the forming tube 2, the filling tube is as shown by figure 2 and 3 Shown has a greater length than the forming tube 2 .

[0020] The device 1 also includes a seaming device 6 with a plurality of seaming units 6 a , 6 b and a folding device 7 for producing outwardly directed creases on the casing material tube produced by means of the forming shoulder 3 . The crease produced in the folding device 7 is then sealed in the sealing device 6 , the sea...

Abstract

The invention relates to an apparatus for producing a pack (20) from a packaging-material web, comprising a forming tube (2), a filling tube (11), which runs, in part, through the forming tube, a forming shoulder (3), which is arranged on the forming tube (2) and is intended for forming a flexible enveloping tube, a folding means (7), which is arranged downstream of the forming shoulder (3), as seen in the conveying direction (A) of the flexible enveloping tube, and a sealing means (6) with a multiplicity of sealing units (6a, 6b), which are arranged downstream of the folding means (7), as seen in the conveying direction (A) of the flexible enveloping tube, wherein the forming tube (2) has a first diameter (D1) and in the filling tube (11) has a second diameter (D2) wherein the first diameter (D1) is greater than the second diameter (D2), wherein the folding means (7) is arranged at the end of the forming tube (2) and wherein the folding means (7) has a parabola-form folding element (8) in order to form folds in the flexible, enveloping tube, the parabola-form folding element (8) being arranged such that a vertex (9) of the parabola-form folding element (8) is directed counter to the conveying direction (A).

Description

technical field [0001] The invention relates to a device for producing packages from a web of packaging material, in particular packages having a plurality of sealing edges in the longitudinal direction of the package. Background technique [0002] Devices for producing packages from packaging material webs are known in various designs from the prior art and are often also referred to as “tubular bag machines”. One use is, for example, food packaging, in which food is stored. DE 10159053 A1 proposes here, for example, to provide sealing seams in the packaging material strip already before the production of the wrapping material tube, which sealing seams form the corners of the packaging after production of the wrapping material tube bag. The device is basically designed, but corresponding machine components are provided for producing the sealing seam in the packaging material web before the actual tube forming, which results in a very large installation space requirement fo...
