[0002] Glass fiber winders are known.

[0003] From DE 1292 779 A and DE 100 61 350 A1 a filament winding method for filaments having a thickness greater than 300 tex is known, wherein the known filament winding method comprises at least one filament transfer step, in which the filament which has been wound onto a winding tube unit and is to be wound onto another winding tube unit is transferred from the winding tube unit to the other winding tube unit and / or vice versa, i.e. from the other winding tube unit to the winding tube unit, wherein the winding tube units are operated at different outer peripheral speeds and / or at different rotational speeds, at least during the transfer of the filament between the winding tube units. Summary of the Invention

[0004] In particular, the object of the present invention is to provide a universal glass fiber winding method, a universal glass fiber winding device, and / or a universal glass fiber winding machine having advantageous properties with regard to the transfer of the filaments between the winding bobbin units during the filament winding process. This object is achieved according to the invention by the features of claims 1, 15, and 16, while advantageous embodiments and further developments of the invention can be derived from the dependent claims.

[0005] The present invention relates to a glass fiber winding method for filaments with a thickness greater than 300 tex, preferably glass fiber direct rovings, which method comprises at least one filament transfer step, in which the filaments that have been wound onto a winding bobbin unit and are to be wound onto another winding bobbin unit are transferred from the winding bobbin unit, in particular a first winding bobbin unit, to another winding bobbin unit, in particular a second winding bobbin unit, and / or vice versa, i.e., from another winding bobbin unit, in particular the second winding bobbin unit, to a winding bobbin unit, in particular the first winding bobbin unit. Winding tube units, wherein, at least during the transfer of the filament between the winding tube units, the winding tube units are operated at particularly significantly different, in particular radial outer peripheral speeds and / or at particularly significantly different rotational speeds, wherein the ratio of the outer peripheral speeds and / or rotational speeds of the winding tube units is selected so that when the filament comes into contact with an idle winding tube unit in the winding tube unit, which was free of filament before the filament transfer, the filament forms a loop, the arc of which points to the introduction point of the idle winding tube unit, at which the introduced filament encounters the idle winding tube unit.

[0006] It is proposed that the formation of the ring is supported by a blowing device and / or by a spraying device, and the blowing device and / or the spraying device are oriented so that the output direction of the blowing medium and / or the spraying medium is at least substantially directed to the open side of the ring and / or to the ring. By the filament winding method according to the present invention, it is advantageous to achieve an optimized filament transfer between the two winding tube units. Advantageously, considerable independence from the necessity of operator intervention can be achieved. Advantageously, the manufacture of a large number of filament winding packages can be achieved in a simple and / or efficient manner, preferably at a high piece rate. Advantageously, a simple, fast and / or operator-independent filament transfer can be achieved. Advantageously, the tucking and / or clamping of the filament on the idle winding tube unit can be achieved, in particular by introducing the filament, so that the winding of the filament on the idle winding tube unit starts automatically. The high reliability of the filament transfer can be advantageously achieved. Advantageously, the tucking and / or clamping of the ring can be accelerated by introducing the filament.

[0007] In particular, the filament is configured as glass fiber. In particular, the filament winding method is performed directly after the production of the filament, in particular glass fiber, or during the production process. Here, it may happen that the filament to be wound, in particular glass fiber, is still wet during the winding period and / or during the execution of the filament transfer step. In particular, in the filament transfer step, the filament at least temporarily contacts two winding bobbin units. In particular, in the filament transfer step, the filament is transferred from a winding bobbin unit that has already carried a plurality of filament windings to another winding bobbin unit that initially did not have a filament winding, and in particular is transferred so that after the filament transfer step, no further filament windings are added to the winding bobbin unit, and further filament windings are added to another winding bobbin unit. In particular, this filament winding method is provided for filaments with a strength greater than 300 tex, but the use of the filament winding method according to the present invention for filaments with a strength less than 300 tex is not excluded or is also possible.

[0008] In particular, the winding tube unit is rotatable, preferably rotatably driven, for example, each idle independent drive drives or is driven by a common drive unit. Preferably, the rotational speed, number of revolutions and / or the outer peripheral speed of the winding tube unit are adjustable. In particular, the rotational speed, number of revolutions and / or the outer peripheral speed of the winding tube unit can be regulated separately from each other. For example, the rotational speed of each winding tube unit can be reduced or increased individually, preferably decelerated or accelerated. The winding tube unit is preferably configured as a cylinder. It is conceivable that each winding tube unit produces a plurality of independent, for example two filament winding packages. In this case, a plurality of filament winding packages are arranged side by side on the winding tube unit along the axial direction of the winding tube unit. In particular, the two winding tube units are at least substantially identical to each other. It is conceivable that the filament is directly wound onto the surface of the winding tube unit, but preferably, each filament winding package is applied to, for example, is sleeved on the winding tube unit, and then the corresponding filament is wound onto this winding sleeve. In particular, the filaments are introduced into the winding tube unit via a filament introduction device. The filament introduction device is particularly configured to move the filaments back and forth parallel to the axial direction of the winding tube during filament introduction. The offset of the filament's back-and-forth motion corresponds in particular to the desired longitudinal extent of the filament winding package. The filaments have a thickness greater than 300 tex, preferably greater than 900 tex. Preferably, the filaments are constructed as direct rovings, particularly having a thickness of 900 to 10,000 tex. "Tex" here should particularly be understood as the gram weight per 10,000 m of filament. In particular, such filaments, particularly direct rovings, are not suitable for direct "tube-to-tube filament transfer," as used in the so-called puff process. This is particularly effective only for filaments with a thickness of less than 300 tex. In particular, the rotational speeds of the winding tube units differ by at least 1%, preferably by at least 2%. Larger rotational speed differences, for example, greater than 10%, greater than 20%, or greater than 30%, are also conceivable. In particular, the outer peripheral speed of the winding tube unit differs by at least a greater value than the rotational speed. In particular, the term "outer peripheral speed," preferably "radial outer peripheral speed," is to be understood as the speed and / or angular velocity of a point on the radially outer surface of the respective radially outermost element of the winding tube unit, the winding sleeve, and the yarn package. In particular, the winding tube unit comprises a winding tube holder and / or a winding sleeve holder or is preferably designed as a winding tube holder and / or a winding sleeve holder.

[0009] In addition, propose that, the outer peripheral speed of winding tube unit and / or the ratio of rotating speed are so selected, make when long filament and the idle winding tube unit that does not have long filament before long filament transfer in two winding tube units contact, the long filament tension force between two winding tube units is reduced compared to the long filament tension force between idle winding tube unit and long filament introduction device.Thus, can advantageously realize simple, fast and / or independent of the long filament transfer of operator.Advantageously, this can further constitute a ring, and this ring can be by the introduction part tuck and / or clamping of long filament, makes to the winding on idle winding tube unit start automatically.In particular, by reducing the long filament tension force in the zone between winding tube unit, produce long filament in the zone between winding tube unit droop or too long, thus, realized that long filament is taken across more than 180 ° by idle winding tube unit on the outer circumference section of idle winding tube unit. In particular, by reducing the filament tension in the area between the winding tube units, the total length of the sections of the filament that are not in contact with one of the winding tube units and are at the same time arranged in the area between the winding tube units is increased to a value that is greater than the shortest distance between the winding tube units, in particular between the filament contact points of the winding tube units, at which the filament is respectively lifted from the winding tube units.

[0010] In addition, it is proposed that during the filament transfer, the winding tube unit that does not have filaments before the filament transfer in the winding tube unit is operated, especially rotated, with a larger outer peripheral speed and / or with a larger rotational speed than the winding tube unit that has been wound with a part of the filament before the filament transfer in the winding tube unit. Thus, it is advantageous to achieve a simple, fast and / or operator-independent filament transfer. Advantageously, it is possible to achieve a reduction in the filament tension in the area between the winding tube units and / or an elongation of the filament in the area between the winding tube units.

[0011] When the ratio of the outer peripheral speed and / or the rotational speed of the winding tube units during the yarn transfer is at least 1.01, preferably at least 1.02 and preferably at least 1.03, an optimal yarn tension reduction and / or optimal yarn elongation in the area between the winding tube units can be advantageously achieved. Larger ratios, for example greater than 1.1, greater than 1.2 or greater than 1.3 are of course also conceivable. In principle, in certain cases, a ratio greater than 1 but less than 1.01 is also sufficient to achieve advantageous effects (rings).

[0012] Furthermore, during the yarn transfer, an optimal yarn tension reduction and / or optimal yarn elongation in the region between the winding tube units can advantageously be achieved when the ratio of the outer peripheral speeds and / or rotational speeds of the winding tube units is at most 5, preferably at most 4, and preferably at most 3.5. Particularly preferably, during the yarn transfer, the ratio of the outer peripheral speeds and / or rotational speeds is at most 1.3. In particular, to achieve the rotational speed ratio and / or outer peripheral speed ratio, the winding tube unit that is already winding is decelerated relative to the idle winding tube unit.

[0013] In particular, the ring is designed as an open ring, with its open side oriented at least substantially away from the incoming yarn. In particular, the ring is initially oriented perpendicularly relative to the surface of an idle winding tube unit. As the ring grows, it preferably tilts over and then lies as a flattened arc on the winding tube unit or on a winding sleeve placed on the winding tube unit. This allows the ring to be tucked around the incoming yarn particularly easily and / or reliably, in particular because it cannot lie to the right or left of the incoming yarn.

[0014] In some embodiments, the present invention relates to a device for producing a plurality of winding tube units, wherein the plurality of winding tube units are connected to the winding tube unit and the winding tube unit is connected to the winding tube unit. In some embodiments, ... In particular, blowing device / spraying device is arranged on one side of long filament, and this side is opposite to the side of the long filament at which the introduction point of idle winding tube unit is located. In particular, blowing device and / or spraying device is such that the formation of supporting ring is made, and the long filament that tension force reduces in the zone between winding tube unit moves toward the surface of idle winding tube unit. In particular, blowing device and / or spraying device is such that the formation of supporting ring is made, and the part of long filament that tension force reduces in the zone between winding tube unit moves more strongly toward importing long filament than the adjacent part of long filament, thus especially produces the concave curvature of long filament when observing from blowing device and / or from spraying device. In particular, blowing device and / or spraying device supports the formation of ring like this, and promptly expands the ring that initially produces by blowing and / or spraying. In particular, blowing device and / or spraying device supports the formation of ring like this, and promptly accelerates the formation of ring by blowing and / or spraying.

[0015] Furthermore, it is proposed that the formation of the loop is supported by selecting the winding surface material or topographical winding surface properties of the following surfaces: the winding surface of an idle winding tube unit, the winding surface of a winding sleeve placed on an idle winding tube unit, or the tuck surface of an (idle) winding tube unit, in particular the tuck ring of the (idle) winding tube unit, arranged laterally adjacent to the winding surface of the winding tube unit or the winding sleeve. This advantageously achieves a high reliability of filament transfer (a high "tuck rate"). Advantageously, the tuck and / or clamping of the loop can be accelerated by the introduction of the filament. In particular, the winding surface material is selected to have good adhesion to glass fibers, such as aluminum, hard-anodized aluminum, stainless steel, coated stainless steel, plastic, or leather. In particular, the topographical winding surface properties are selected to have surface properties that increase friction with the glass fibers, such as the surface of a woven glass fiber tape, a tie tape, a sandpaper surface, a corrugated surface, or an extremely smooth polished surface. In particular, the winding sleeve is designed as a hollow cylinder. In particular, the winding sleeve is configured to carry the filament and provide the filament for subsequent further processing. In particular, the tuck surface is configured to provide the filament with a surface having increased friction and / or adhesion, preferably compared to the surface on which the filament is already wound, so that the filament contacting the tuck surface is at least partially entrained by the rotational movement of the tuck surface. In particular, the tuck surface can also have the aforementioned winding surface material and / or topographic winding surface characteristics. Preferably, the tuck surface is arranged between two adjacent winding sleeves that are sleeved on a winding tube unit or another winding tube unit. In particular, the tuck surface separates two winding sleeves that are arranged axially side by side on the winding tube unit. In particular, in this case, the winding tube unit has a tuck ring that extends around the circumference of the winding tube unit and provides the tuck surface.

[0016] When the ring extends so far toward the introduction point that the ring falls below the introduction of the long yarn and is preferably clamped by the introduction of the long yarn, a high reliability of the long yarn transfer (a high "tuck rate") can be advantageously achieved. In particular, the ring first increases in a vertical orientation toward the introduction of the long yarn and then tilts so that the ring is located as a flat arc on the winding area of the winding tube unit or the winding sleeve arranged on the winding tube unit, so that the subsequent winding of the long yarn stretches and clamps this arc. In particular, the ring is clamped by the introduction of the long yarn so that the ring is also clamped and remains clamped below the long yarn winding subsequently formed on the winding tube unit. In particular, the ring is clamped by the introduction of the long yarn so that the rotation of the winding tube unit where the ring is clamped produces tension on the portion of the long yarn arranged in the middle area between the winding tube units. In particular, the ring is clamped by the introduction of the long yarn so that the two winding tube units apply tension to the portion of the long yarn arranged between the winding tube units, each acting in opposite directions.

[0017] In addition, propose that, after the filament transfer step, preferably in at least one filament separation step after the ring is clamped below the imported filament, the filament of transfer, especially due to the different outer peripheral speeds of the two winding tube units and / or due to the different rotating speeds of the two winding tube units, preferably due to the different tensioning directions of the filament in the middle area between the two winding tube units, is torn in the middle area between the two winding tube units.Thus, it is advantageous to realize the separation of the filament after completing the filament winding package in a particularly simple, effective and / or less maintained manner.Preferably, tearing is only carried out due to the tensioning force to the filament in the middle area produced by the rotation of the winding tube unit.Alternatively, however, it can also be envisaged that the separation step is supported by a tearing edge or a cutting device that is particularly arranged in the middle area.For example, this tearing edge can for example be provided by a particularly S-shaped separating plate, which is preferably arranged in the middle area. The cutting device can be provided for passive cutting of the filaments in the intermediate region (the cutter or knife remains stationary during the filament separation step) or for active cutting (the cutter or knife moves during the filament separation step). In particular, the cutting and / or tearing of the filaments in the intermediate region is only carried out when the ring has been successfully clamped under the incoming filaments and thus, in particular, the filament transfer between the winding tube units (filament transfer step) has been achieved.

[0018] In addition, it is proposed that during the filament transfer, the introduction part of the filament or the part of the filament extending between the winding tube units is deflected in the direction of the idle winding tube unit in the winding tube unit that has no filament before the filament transfer by a deflection and / or pressure element, especially a deflection and / or pressure roller, which is pivotally and / or displaceably supported. Thus, the high reliability of the filament transfer (high "tuck rate") can be advantageously achieved. Advantageously, the tuck and / or tightening of the ring can import the filament to accelerate. In particular, the ratio of the circumference of the idle winding tube unit that contacts the imported filament is increased by the deflection and / or pressure element. Preferably, the deflection and / or pressure element is arranged to deflect the filament so that at least 180°, preferably at least 190°, of the total circumference of the idle winding tube unit contacts the filament. The winding portion that is produced by deflection and / or pressing element of winding tube unit less or larger, especially idle winding tube unit and the embodiment that does not have deflection and / or pressing element are compared with the winding portion that increases, certainly also can be imagined.Thus, can advantageously increase the friction and / or adhesion of long filament and idle winding tube unit, make especially can promote / realize / improve long filament by the driving of the rotary motion of idle winding tube unit and / or the formation of ring and / or the clamping of ring below the long filament of guiding.Here, deflection and / or pressing element can be configured as rotatable element, for example, be configured as deflection roller, or be configured as fixed (non-rotatable) element, for example, be configured as deflection rod or deflection pad.When being configured as fixed element, long filament sweeps the surface of deflection and / or pressing element.When being configured as rotatable element, deflection and / or pressing element rotate together at least in part with the motion of the importing long filament that sends into subsequently. In particular, the deflection and / or pressure element configured as a deflection and / or pressure roller does not have its own rotational drive. In particular, the rotation axis of the deflection and / or pressure element configured as a deflection and / or pressure roller is oriented at least substantially parallel to the rotation axis of the winding tube unit. In particular, the deflection and / or pressure element is supported on a translation and / or pivoting device, by means of which the deflection and / or pressure element can be at least temporarily introduced into an intermediate area between the winding tube units or into an introduction area of an idle winding tube unit, in which the filament is introduced into the idle winding tube unit. In particular, the translation and / or pivoting device includes at least one at least pivotable and / or at least translatable supporting arm, on which the deflection and / or pressure element is mounted.

[0019] In addition, it is proposed that during the filament transfer, the introduction part of the filament or the part of the filament extending between the winding tube units is pressed onto the idle winding tube unit by deflection and / or pressing element, especially deflection and / or pressing roller.Thus, it is advantageous to achieve the high reliability (high "tuck rate") of the filament transfer.Advantageously, the adhesion of the filament to the idle winding tube unit or the friction of the filament to the idle winding tube unit can be increased.Thus, it is advantageous to achieve the filament transfer step with a particularly large number of winding sleeves made of different materials, especially also with so-called "low friction winding sleeves", which for example have a surface made of polytetrafluoroethylene material.Advantageously, in this way, the introduction speed for the filament of the other one of the two winding tube units is determined by the outer peripheral speed of the idle winding tube unit and / or by the rotating speed. In particular, the speed of importing yarn is first determined by the winding tube unit that has been partially wound, until idle winding tube unit fully contacts the importing long filament of the winding tube unit upstream that has been partially wound, so that idle winding tube unit is assumed to determine the task of importing speed. In particular, deflection and / or pressing element, in particular deflection and / or pressing roller are so elastically supported that the longitudinal axis, in particular axis of rotation of deflection and / or pressing element can move along the radial direction of winding tube unit. Thus, it is advantageous to reduce undesirable effects, such as noise generation or contact loss, by the unevenness in the winding tube surface, in the winding sleeve surface, such as due to seam or edge, such as injection molding separation causes. Preferably, the winding sleeve that first contacts and imports the long filament constitutes the introduction speed for determining importing long filament and / or is used to produce the introduction device, in particular introduction drive of the introduction motion of importing long filament. Alternatively, however, it is also possible to imagine the filament conveying device that is constituted and / or arranged separately from the winding sleeve. In particular, after the filament separation step is performed, the deflecting and / or pressing element is removed from the winding tube unit. In particular, after the filament separation step is performed, the deflecting and / or pressing element is removed from the intermediate area between the winding tube units.

[0020] In addition, what is proposed is that two winding tube units are eccentrically supported on the rotating disk separately, and this rotating disk rotates so in the long filament transfer step, makes the idle winding tube unit that does not have long filament in the winding tube unit before long filament transfer contacts with the introduction part of long filament.Thus, can advantageously make the particularly simple and / or efficient realization and / or execution of long filament transfer step become possibility.In particular, the axis of rotation of winding tube unit and rotating disk is at least basically oriented parallel to each other.In particular, the winding tube unit is at least basically arranged on the rotating disk relative to each other.In particular, the winding tube unit is arranged on the rotating disk, so that the center point of rotating disk rotates approximately 180 °.In particular, the structure that comprises rotating disk and two winding tube units is mirror-symmetrical, especially mirror-symmetrical with respect to mirror plane, the axis of rotation of rotating disk extends in this mirror plane, and this mirror plane divides rotating disk into two halves.Yet, as the alternative of the embodiment with rotating disk, for example, also can be imagined that the winding tube unit is movably supported on the groove connecting track with any suitable shape.

[0021] When two winding tube units rotate along identical and constant direction of rotation during whole filament transfer step and preferably also during the filament separation step in which filament is separated between winding tube units, can advantageously realize the particularly simple design of the filament winding device for filament winding method. Advantageously, it is sufficient to carry out relatively simple drive and relatively simple control to the motion of winding tube unit. In particular, there is no need for the possibility of rotation reversal of the rotary motion of winding tube unit. For example, different outer peripheral speeds and / or rotating speeds can only be realized by slowing down or accelerating one of the winding tube units, especially the winding tube unit that has been partially wound, relative to another winding tube unit.

[0022] The present invention also relates to a glass fiber winding device for filaments having a thickness of more than 300 tex, preferably glass fiber direct rovings, in particular for carrying out a glass fiber winding method, comprising a winding tube unit, a further winding tube unit and at least one filament transfer unit, which is configured to transfer the filament to be wound onto the winding tube unit or onto a winding sleeve that can be connected to the winding tube unit from the winding tube unit to the further winding tube unit and / or vice versa, i.e., to transfer the filament from the further winding tube unit to the winding tube. The invention relates to a unit wherein the filament transfer unit is configured to operate the winding tube units at different peripheral speeds and / or different rotational speeds, at least during the transfer of the filament between the winding tube units, wherein the ratio of the peripheral speeds and / or rotational speeds of the winding tube units can be selected such that when the filament contacts an idle winding tube unit of the winding tube unit that was free of filament before the filament transfer, the filament forms a loop whose arc points toward the introduction point of the idle winding tube unit, at which the introduced filament encounters the idle winding tube unit. It is proposed that the glass fiber winding device include a blowing device and / or a spraying device, which is configured to support the formation of the loop, wherein the blowing device and / or the spraying device are oriented such that the discharge direction of the blowing medium and / or the spraying medium is at least substantially directed toward the open side of the loop and / or toward the loop. Advantageously, a large number of filament winding packages can be produced in a simple and / or efficient manner, preferably at a high unit rate.

[0023] Furthermore, a glass fiber winding machine is proposed which, in particular, realizes the advantages of glass fiber winding devices and has at least one of the glass fiber winding devices.

[0024] In this context, the glass fiber winding method according to the present invention, the glass fiber winding device according to the present invention, and / or the glass fiber winding machine according to the present invention are not limited to the applications and embodiments described above. In particular, the glass fiber winding method according to the present invention, the glass fiber winding device according to the present invention, and / or the glass fiber winding machine according to the present invention may have a number of individual elements, components, units, and method steps different from the number given herein to achieve the functions described herein.

[0049] Figure 1 A portion of a filament winding machine 58 is schematically shown. The filament winding machine 58 is configured as a glass fiber winding machine. The filament winding machine 58 has one or more filament winding devices 54. The filament winding device 54 of the filament winding machine 58 and / or one of the plurality of filament winding devices 54 is arranged in a Figure 1 exemplarily shown in FIG.

[0050] The filament winding device 54 is configured as a glass fiber winding device. The filament winding device 54 is configured to wind the filament 10. The filament 10 is configured as a glass fiber, for example. The filament 10 is configured as a glass fiber direct roving. The filament winding device 54 is configured to produce a wound filament winding package 70 (see also Figure 6 ). The glass fiber winding device is configured to produce a wound glass fiber winding package. The filament winding device 54 is configured for filaments 10 having a thickness greater than 300 tex. The filament winding device 54 is optimized for winding and transferring glass fibers having a thickness between 900 tex and 10,000 tex. The filament winding device 54 is configured to perform the filament winding method shown in the figure.

[0051] The filament winding device 54 has a winding tube unit 14. The winding tube unit 14 is rotatably supported around an axis of rotation 60 extending parallel to the longitudinal axis of the winding tube unit 14. The filament winding device 54 has another winding tube unit 24. The other winding tube unit 24 is rotatably supported around an axis of rotation 62 extending parallel to the longitudinal axis of the other winding tube unit 24. The winding tube units 14, 24 are configured to wind the filament 10 by rotating it around their axes of rotation 60, 62. In the illustrated case, two winding sleeves 32 are respectively applied to the winding tube units 14, 24. The winding sleeves 32 are configured as hollow cylinders that can be sleeved onto the winding tube units 14, 24. The winding sleeves 32 each have a winding surface 30. The winding surface 30 of the winding sleeve 32 is composed of a winding surface material that helps to drive the filament 10 in contact with the winding surface 30. For example, Figure 1 The winding surface material of the winding sleeve 32 is carton. Alternative winding surface materials for the winding sleeve 32 can be envisaged. Alternatively or additionally, the winding sleeve 32 can each have special topographical winding surface properties of the winding surface 30. The topographical winding surface properties of the winding surface 30 of the winding sleeve 32 are configured so as to facilitate the entrainment of the filament 10 in contact with the winding surface 30. For example, Figure 1 The winding surface 30 of the winding sleeve 32 has a topographical winding surface characteristic characterized by a particular roughness. Alternative topographical winding surface characteristics of the winding sleeve 32 can be envisioned.

[0052] The winding tube units 14, 24 have a tuck ring 68. The tuck ring 68 is arranged over approximately half the axial length of the respective winding tube units 14, 24. The tuck ring 68 surrounds the entire circumference of the winding tube units 14, 24. A winding sleeve 32 is arranged on both sides of the tuck ring 68 in the axial direction of the winding tube units 14, 24. The tuck ring 68 is arranged laterally next to the winding surface 30 of the winding sleeve 32. The tuck ring 68 is configured to exert significantly increased friction or adhesion to the filament 10 compared to the surface of the filament winding package 70 wound onto the winding tube units 14, 24. To this end, the tuck ring 68 has a tuck surface 34. The tuck surface 34 of the tuck ring 68 is composed of a winding surface material that helps to carry the filament 10 in contact with the tuck surface 34. For example, Figure 1 The winding surface material of the tuck ring 68 is aluminum. Alternative winding surface materials for the tuck ring 68 are conceivable. Alternatively or additionally, the tuck ring 68 can each have special topographical winding surface properties of the tuck surface 30. The topographical winding surface properties of the tuck surface 34 of the tuck ring 68 are configured so as to facilitate the entrainment of the filament 10 in contact with the tuck surface 30. For example, Figure 1The tuck surface 34 of the tuck ring 68 has a topographical winding surface characteristic characterized by a particularly pronounced smoothness. Alternative topographical winding surface characteristics of the tuck ring 68 can be envisioned.

[0053] The filament winding device 54 has a turntable 48. The turntable 48 is rotatably supported around a central rotation axis 64. The rotation axes 60, 62 of the winding tube units 14, 24 and the rotation axis 64 of the turntable 48 extend approximately parallel to each other. The turntable 48 has a transfer rotation direction 66. The turntable 48 moves along the transfer rotation direction 66 so that the filament 10 contacts the idle winding tube unit 24 of the winding tube units 14, 24. However, in some parts of the filament winding method, it is also conceivable and possible to rotate in the direction opposite to the transfer rotation direction 66. The winding tube units 14, 24 have rotation directions 50, 52. The two winding tube units 14, 24 rotate along the rotation directions 50, 52 during the entire filament transfer method. These rotation directions 50, 52 are identical to each other and remain constant during the entire filament transfer method. The rotation directions 50, 52 of the winding tube units 14, 24 are opposite to the transfer rotation direction 66 of the turntable 48. The winding tube units 14, 24 are arranged eccentrically on the turntable 48. A rotation of the turntable 48 about the axis of rotation 64 produces a displacement of the entire winding tube unit 14, 24 along a circular path.

[0054] The filament winding device 54 has a filament transfer unit 56. The filament transfer unit 56 is configured to transfer the filament 10 to be wound onto the winding sleeve 32 that can be connected to the winding tube units 14, 24 from the winding tube unit 14 to the other winding tube unit 24. The filament transfer unit 56 is configured to operate the winding tube units 14, 24 at different outer peripheral speeds and / or at different rotational speeds, at least during the transfer of the filament 10 between the winding tube units 14, 24. Here, the ratio of the outer peripheral speeds and / or rotational speeds of the winding tube units 14, 24 is selected by the filament transfer unit 56 so that when the filament 10 contacts the idle winding tube unit 24 of the two winding tube units 14, 24, which does not have any filament 10 before the filament 10 is transferred, the filament tension between the two winding tube units 14, 24 is compared to the filament tension between the idle winding tube unit 24 and the filament introduction device 16 (see also Figure 7 ) between the yarn tension is reduced. In addition, the ratio of the outer peripheral speed and / or the rotational speed of the winding tube units 14, 24 is selected by the yarn transfer unit 56 so that the yarn 10 forms a loop 18 when it contacts the idle winding tube unit 24. Here, the loop 18 formed has an arc 20, which points to the introduction point 22 of the idle winding tube unit 24, where the introduced yarn 10, 26 encounters the idle winding tube unit 24 (see also Figure 3 or Figure 4During the transfer of the filament 10, the ratio of the outer peripheral speeds and / or rotational speeds of the winding tube units 14, 24 is at least 1.01. Furthermore, during the transfer of the filament 10, the ratio of the outer peripheral speeds and / or rotational speeds of the winding tube units 14, 24 is at most 3.5. To this end, during the transfer of the filament 10 by the filament transfer unit 56, the idle winding tube unit 24 is operated at a greater outer peripheral speed and / or a greater rotational speed than the partially wound winding tube unit 14.

[0055] Figures 1 to 6 The filament winding device 54 is schematically shown at different time periods of a filament winding method. Figure 1 The situation that the filament winding package 70 is produced on the winding tube unit 14 by the rotation of the winding tube unit 14 is shown. During the production of the filament winding package 70, the filament 10 is guided by the filament axial guide unit 72 (see also Figure 7 ) reciprocates parallel to the axis of rotation 60 of the winding bobbin unit 14 to produce uniform winding. Figure 2 The other winding tube unit 24 is shown in contact with the filament 10 by the rotation of the turntable 48 in the transfer rotation direction 66. During the rotation of the winding tube units 14, 24 by means of the turntable 48, the filament 10 is brought by the axial filament guide unit 72 to the axial edge region of the corresponding filament winding package 70, in particular closer to the tuck ring 68. For the sake of clarity, only one filament 10 is shown. Figure 3 The situation of producing loop 18 is shown. For the sake of clarity, only one filament 10 is shown. Figure 4 The ring 18 is shown in a state where it has been tilted, is located on the winding sleeve 32 and is tucked and clamped by the lead-in part of the thread 10, 26. In this way, in the tensioning direction 38 pointing to the other winding tube unit 24, the thread 10, 44 is clamped in the intermediate region 42 (see in particular the intermediate region 42) arranged between the winding tube units 14, 24. Figure 1 ) creates tension on the portion in it.

[0056] For the sake of clarity, only one filament 10 is shown. Figure 5 The figure shows a situation in which the tensioning force in the tensioning direction 38 is continuously increased by winding the filament 10 onto the winding sleeve 32 until the portion of the filament 10, 44 arranged in the middle region 42 tears. Here, the winding tube unit 14 generates tension in the portion of the filament 10, 44 arranged in the middle region 42 in the other tensioning direction 40 by its own rotation. The tensioning direction 38 and the other tensioning direction 40 are oriented opposite to each other. Figure 6The filament 10 of the filament winding package 70 of the winding tube unit 14 is shown separated from the lead-in portion of the filament 10, 26 and wound onto another winding tube unit 24 with only the filament 10. Now, the filament winding package 70 can be removed from the winding tube unit 14 and a new winding sleeve 32 can be put onto the winding tube unit 14 so that the winding process can be performed again (in the opposite way). Figures 1 to 5 to transfer the filament 10 from the other winding bobbin unit 24 (return) to the winding bobbin unit 14.

[0057] Figure 3 Illustratively, a supporting device is shown for supporting the formation of a ring 18 that is important to the filament winding method. The filament winding device 54 has a blowing device 28. The blowing device 28 is provided for the directional output of a gas stream 74, preferably an air stream. Alternatively or additionally, the filament winding device 54 can have a spraying device. Then, the spraying device can be provided for the directional output of a liquid. The blowing device 28 and / or the spraying device are arranged to support, especially accelerate the formation of the ring 18 and / or expand its extension to the introduction point 22. The blowing device 28 is arranged to output a gas stream 74, which is directed to the introduction portion of the filaments 10, 26. The blowing device 28 is arranged to blow the gas stream 74 into the opening of the ring 18. The blowing device 28 is arranged to blow the gas stream 74 into the inner side of the arc portion 20 of the ring 18. Alternative or additional spraying devices can have the same task and / or can have the additional task of applying the liquid that supports adhesion to another winding tube unit 24.

[0058] The filament winding device 54 has a deflecting and / or pressing element 46. The deflecting and / or pressing element 46 can be configured as a deflecting and / or pressing roller. The deflecting and / or pressing element 46 is arranged to, during the transfer of the filament 10, the introduction part of the filament 10, 26 (see also Figures 7 to 15 ) or the portion of the filament 10, 44 extending in the intermediate region 42 between the winding bobbin units 14, 24 (see also Figures 16 to 22 ) is deflected in the direction of the idle winding tube unit 24. The deflecting and / or pressing element 46 is arranged to expand the winding of the idle winding tube unit 24 by the introduction part of the yarn 10, 26 during the transfer of the yarn 10. The deflecting and / or pressing element 46 can be as follows Figure 3 The exemplary embodiment is shown as being formed in a common component with the blowing device 28 and / or with the spraying device. Alternatively, however, the deflection and / or pressure element 46 can also be formed as a component separate therefrom. Figure 3In the example of FIG, the deflection and / or pressing element 46 constitutes only a deflection element and not a pressing element, since it does not contact the further winding tube unit 24. However, it is also conceivable and possibly even advantageous for the deflection and / or pressing element 46 to be able to press onto the respective winding tube unit 14, 24, i.e. in particular to contact the further winding tube unit 24. The deflection and / or pressing element 46, just like the blowing device 28 and / or the spraying device, can be used alternately for the winding tube unit 14 and for the further winding tube unit 24, depending on the direction in which the thread 10 is currently being transferred.

[0059] Figures 7 to 15 and Figures 16 to 22 The diagrams each schematically illustrate the sequence of a filament winding method with a filament winding device 54. The two sequences differ in the arrangement and movement of the pivotably and displaceably mounted deflecting and / or pressure element 46. Figures 7 to 22 The deflection and / or pressing element 46 shown in FIG can also contain or constitute a blowing device 28 or a spraying device. In the center of the turntable 48, in particular in the middle area 42 between the winding tube units 14, 24, Figures 7 to 22 In each of the examples, an optional tearing plate 76 is shown. The tearing plate 76 is arranged such that after the filament 10 has been successfully transferred to the other winding tube unit 14, 24, when the filament 10 is tensioned in the intermediate region 42 using different tensioning directions 38, 40, the filament 10 tensioned in the intermediate region 42 comes into contact with the tearing edges 78, 80 of the tearing plate 76 and thus supports the tearing of the portion of the filament 10, 44 arranged between the winding tube units 14, 24. It is conceivable that the tearing edges 78, 80 are designed as cutters or knives.

[0060] Figure 23Shown is a schematic flow chart of a filament winding method for a filament 10 having a thickness greater than 300 tex, such as a glass fiber direct roving. In at least one method step 82, filament 10 is produced. For example, filament 10 is produced as glass fiber in a known manner. In at least another method step 84, filament 10 is guided to a filament winding machine 58, particularly a filament winding device 54. In at least one method step 86, filament 10 is tucked and wound onto one of winding tube units 14, 24, particularly onto winding tube unit 14. In at least one filament transfer step 12, filament 10 to be wound is transferred from winding tube unit 14 to another winding tube unit 24. The filament winding method preferably comprises a plurality of successive filament transfer steps 12, wherein filament 10 is alternately transferred from winding tube unit 14 to another winding tube unit 24 and transferred from another winding tube unit 24 to winding tube unit 14. In the yarn transfer step 12, the winding tube units 14, 24 are operated at different outer peripheral speeds and / or at different rotational speeds, at least during the transfer of the yarn 10 between the winding tube units 14, 24. Here, the ratio of the outer peripheral speeds and / or rotational speeds of the winding tube units 14, 24 is selected to a value greater than 1.01 and less than 3.5 so that when the yarn 10 contacts the idle winding tube unit 24, the yarn tension between the two winding tube units 14, 24 is reduced compared to the yarn tension between the idle winding tube unit 24 and the yarn introduction device 16, so that the yarn 10 forms a loop 18, the arc 20 of which points to the introduction point 22 of the idle winding tube unit 24 (see Figure 3 、 Figure 4 and Figure 14 ). In this case, in the filament transfer step 12, the idle winding tube unit 24 is operated at a greater outer peripheral speed and / or a greater rotational speed than the already partially wound winding tube unit 14.

[0061] In at least one sub-step 94 of the filament transfer step 12, the turntable 48 is rotated so that the idle winding tube unit 24 comes into contact with the lead-in portion of the filament 10, 26 (see Figure 2 、 Figure 9 and Figure 19 ). As a result, the introduced portion of the thread 10, 26 is partially wound around the free winding tube unit 24, but by less than 180°, in particular less than 120° (see Figure 11 In at least one further sub-step 96 of the filament transfer step 12, during the transfer of the filament 10, the introduction section of the filament 10, 26 is deflected by a pivotably and / or displaceably supported deflecting and / or pressing element 46 in the direction of the idle winding tube unit 24 (see Figures 18 to 20In at least one further sub-step 98 of the filament transfer step 12, during the transfer of the filament 10, the lead-in portion of the filament 10, 26 is pressed by the deflecting and / or pressing element 46 onto the idle winding tube unit 24 (see Figure 21 ). Alternatively, in an alternative sub-step 96 ′, the portion of the filament 10 , 44 extending between the winding tube units 14 , 24 can be deflected by the deflection and / or pressure element 46 in the direction of the free winding tube unit 24 (see Figure 12 and Figure 13 ) and press onto the idle winding bobbin unit 24 (see Figure 13 ).

[0062] In at least one further sub-step 88 of the filament transfer step 12, the formation of the loop 18 is supported by a blowing device 28 and / or a spraying device. To this end, a gas stream 74 or a liquid stream is blown or sprayed onto the filament 10. In at least one further sub-step 90 of the filament transfer step 12, the formation of the loop 18 is supported by the interaction of the filament 10 with the selected winding surface material and / or selected topographical winding surface characteristics of the winding surface 30 of the winding sleeve 32 and / or the tuck surface 34 of the tuck ring 68. In at least one further sub-step 92 of the filament transfer step 12, the extension of the loop 18 is expanded to such an extent that the loop 18 falls over and rests on the winding surface 30 of the winding sleeve 32. In another sub-step 92, the extension of the loop 18 is expanded to such an extent that the loop 18 extends so far toward the introduction point 22 that the loop 18 is clamped below the introduced filaments 10, 26.

[0063] In at least one filament separation step 36 following the filament transfer step 12, the transferred filament 10 is torn in the middle region 42 between the two winding bobbin units 14, 24 due to the different tensioning directions 38, 40 on the filament 10 (see Figure 5 、 Figure 15 and Figure 22 The tearing of the filaments 10 can optionally be supported by partial cutting, severing or guiding through the tearing edges 78, 80. During the filament transfer step 12 and also during the filament separation step 36, the two winding bobbin units 14, 24 rotate in the same and constant rotation direction 50, 52.

[0064] In at least one further method step 100, the finished wound and separated filament winding package 70 is removed from the winding tube unit 14. In the case shown in the figure, each winding tube unit 14, 24 is configured to receive two winding sleeves 32 and to produce two filament winding packages 70 simultaneously. However, it is also conceivable that each winding tube unit 14, 24 has more or fewer filament winding packages 70. In at least one further method step 102, a new, empty winding sleeve 32 is applied to the winding tube unit 14. Thereafter, another filament transfer step 12' begins, in which the filament 10 is transferred from the other winding tube unit 24 to the winding tube unit 14.
