EP3604656B1 - Method and device for forming a loop - Google Patents

Description

The invention relates to a method and a device for forming a loop from flexible strip material and for fixing the loop to a piece of textile, in particular to the edge of a piece of textile.

Such devices and methods are widely known in the prior art. From the EP 0 607 196 B1 a device and a method for its operation are known with which labels, including loop labels, are produced from ribbon material. For this purpose, a strip material introduced into a feed device is transported by means of the feed device in the direction of clamping tongs. The clamping tongs take over the strip material, namely one end of the strip material, while the feed device is moved back to its starting position. Then a folding plate is set in motion, the direction of movement of which is aligned perpendicularly to the surface of the strip material that is stretched out. The folding plate is moved in the direction of the strip material and shortens it, leaving a simple loop arises. The folding plate is fed with the band into a positioning tongs, which closes at the same time with scissors, which separates the band material into a small band, with the positioning tongs taking over the finished folded loop, while the folding plate is returned to its original position. The ends of the strap are then welded and the loop is transported to a sewing station, where it is fixed to the hem of a textile in the form of a label.

Alternatively, a flag label can also be produced with the device. The folding plate is then pushed back after the scissors have separated the strap, whereby the loop previously folded in the positioning tongs is straightened. Only after straightening does the positioning tongs close and the flag can be fixed as a flag label on a piece of textile. It is also possible to make U-shaped loops. However, the device has to be expanded for this purpose. In this embodiment, a carriage with an adjustment option for the width of the tape and a guide is arranged on the machine frame. In addition, a shaped plate and a U-shaped folding plate are arranged one above the other in the device, with the tape resting on the shaped plate. The folding plate is lowered from a position above the belt section and moved relative to the forming plate so that it lies below the plane of the belt. By moving the folding plate relative to the shaped plate, the Fold the shank of the ribbon over and create a U-shaped loop. The shaped sheet then pushes the loop into the positioning pliers in the manner described.

Another device is from WO 01/92626 A1 known.

The disadvantage of the solutions known from the prior art is that different devices are required to produce different label formats, so that if there is a change in production, for example from a simple loop label to a U-shaped label, complex conversion measures have to be taken in one device. for example, replacing a device for making a simple loop label with another device for making a U-shaped label. Although is from the EP 0 607 196 B1 a device is known by means of which different types of labels can be produced, but here too additional elements have to be introduced into the device in order, for example, to be able to produce a U-shaped label. A v-shaped label cannot be produced with this device.

Proceeding from this state of the art, the object of the invention is to provide a device and a method by means of which it is particularly cost-effective and simple Way a variety of label formats can be produced.

To solve this problem, the invention proposes a method according to claim 1.

The strap material that is formed into a loop can be flat strap material, cord, or any other strip material. Any flexible material can be used as the band material.

The end of the strip that is at the front in the conveying direction is clamped when it reaches a certain position. After the first clamping point has been clamped, further strip material is conveyed out of the supply of strip material or is conveyed away from a supply reel of strip material until the strip has a length sufficient for loop formation.

For this purpose, the strip material can, for example, be conveyed further by a conveyor device and, as it were, pushed past the clamping point and transported, with the following strip material turning over and forming a loop. The strip material is fed until the strip has formed a simple loop of sufficient length.

Alternatively, the strip material can also be conveyed out of the supply of strip material by a clamping element that holds the strip at the first clamping point, for example by moving the element in the conveying direction and applying a tensile force to the strip material until the strip has sufficient force to form a loop has length. In this case initially there is no loop, but the strip forms a straight strip of tape.

The strip, after being in the form of a simple loop or straight strip of tape of sufficient length, is clamped at a second nip spaced from the first nip and which holds a second end of the strip.

In the event that a simple loop has already been formed and the strip is clamped at the first and a second clamping point, the clamping points lie one above the other. The band material is severed in the direction of the band material following the second clamping point and the single loop can be fixed to the edge of the piece of textile.

Alternatively, the simple loop can be further processed by adjusting the first end or the second end relative to the other end in the plane defined by the strip, transverse to the direction of movement of the strip material, so that the ends are juxtaposed and out of the simple loop a v-shaped loop is formed. Both ends can also be adjusted relative to one another in the plane spanned by the strip, transversely to the direction of movement of the strip material, so that the ends are arranged next to one another and a v-shaped loop is formed.

Alternatively, the simple loop can also be further processed in such a way that one of the ends is pivoted about a pivot axis relative to the respective other end, so that a U-shaped loop is formed. Preferably, one of the ends is then adjusted relative to the respective other end and away from this end in the plane spanned by the strip, so that the U-shaped loop is taut. Both ends can also be moved away from each other in this plane in order to tighten the loop.

In the event that the strip material is just being conveyed out of the strip material supply and no loops have yet been formed, the first end or the second end can be pivoted about at least one pivot axis, so that the ends are arranged one above the other or at least partially overlapping or next to one another and the strip forms a plain loop, a V-shaped loop or a U-shaped loop. If the ends are arranged one above the other after pivoting and the strip is formed into a simple loop, at least one of the ends can then be adjusted relative to the other end in the plane spanned by the strip and away from it, so that the ends are arranged next to each other and a v-shaped loop is formed instead of the simple loop. Adjusting one end away from that other end or both ends away from each other can also be done when the ends are placed side by side and the strip forms a U-shaped loop to convert the loop into a To stretch U-shape with spaced legs.

Alternatively, in the event that the strip material is just being conveyed out of the supply of strip material and no loop has yet been formed, one of the ends can be relative to the other end or both ends can be relative to one another in the plane spanned by the strip or parallel to it level to be adjusted. As a result, a simple loop shape can be produced, namely if the first end or the second end is moved towards the other end or both ends are moved towards one another so that the ends are arranged one above the other, or a v-shaped loop if namely both ends or the first end or the second end is moved obliquely in the direction of the respective other end, so that the ends are arranged next to one another or at least partially overlapping.

During the process, the strip material is severed in the direction of the strip material following the second clamping point. The separation can take place after clamping at the second clamping point and possibly before pivoting or adjusting the ends, with the advantage that both ends can be moved freely when pivoting or adjusting. However, the separation can also only take place after the pivoting or adjustment, which results in the advantage that time can be saved.

Depending on the orientation of the loop, the first end and the second end must then be aligned in a position transverse to the piece of fabric in order to position the ends on the edge of the piece of fabric and to fasten the ends to the piece of fabric. This is necessary, for example, when the conveying direction of the strip material runs parallel to the edge of the piece of textile. In this case, the ends of the finished loop are positioned away from the edge of the piece of fabric and must be aligned towards the edge in order to be able to attach them to the piece of fabric. The alignment can be done by adjusting or pivoting the ends or in any other way. If the loop is already correct when it is created, i.e. aligned across the edge of the textile piece, the ends do not need to be aligned. This correct alignment is achieved when the conveying direction of the strip material extends approximately transversely to the edge area of the piece of textile.

The formed loop can then be fixed to the piece of textile in any desired manner.

The process steps can be implemented particularly simply, variably and inexpensively and can be carried out as desired in a compact, simply constructed device. This eliminates the need for time-consuming changes or conversion measures that had to be carried out with conventional methods when production is changed from one label format to another label format should be switched. With the present method, it is sufficient to program the device executing the method according to the desired loop formation and to adjust the sequence or the implementation of the method steps accordingly.

It is preferably provided that the conveying direction does not run parallel, but preferably essentially transversely to the edge of the piece of textile.

A strip of the band material is preferably brought up to the textile approximately transversely to the edge of the textile piece. This alignment approximately transversely to the edge area results in the advantage that all label formats can be fixed to the edge of the textile piece without subsequent turning of the loop.

The term transverse to the conveying direction is not to be understood in such a way that it necessarily has to be a vertical alignment; it also includes oblique-angled alignments, for example.

Provision is preferably made for the pivot axis to run essentially perpendicularly or parallel to the plane spanned by the strip of band material.

In the event that after the strip material has been conveyed out, a simple loop has already been formed and the strip on a first and a second clamping point is held clamped, the ends or the clamping points are arranged one above the other. One of the ends is then pivoted about a pivot axis that runs parallel to the plane spanned by the strip, relative to the respective other end, so that the simple loop is transformed into a U-shaped loop. Pivoting about the parallel pivot axis is particularly advantageous because it does not interfere with the area in front of the tape strip, for example the conveying area of the piece of textile, but rather moves next to the piece of textile or its edge area.

In the event that the strip material is just being conveyed out of the supply of strip material and no loop has yet been formed, the first end or the second end is pivoted about at least one axis. If one of the ends is pivoted about a pivot axis which is aligned essentially perpendicular to the plane spanned by the strip, a U-shaped loop is formed. On the other hand, if in this case one of the ends is pivoted about a pivot axis which is aligned essentially parallel to the plane spanned by the strip, then a simple loop or a V-shaped loop is formed.

If, in the event that the band material is just being conveyed out of the band material supply and no loop formation has taken place, one of the ends first about a pivot axis in the Oriented essentially parallel to the plane spanned by the strip, a simple loop is formed. This end can then be pivoted about a further pivot axis, which is aligned essentially perpendicular to the plane spanned by the strip, so that a U-shaped loop is formed.

The first or second end can thus be pivoted about a pivot axis which runs parallel or perpendicular to the plane spanned by the strip of band material.

However, it is also possible for one of the ends to be pivoted about a plurality of pivot axes, for example a pivot axis which runs essentially perpendicularly and a pivot axis which runs essentially parallel to the plane spanned by the strip of strip material.

Provision is preferably made for the first clamping point to be moved in the conveying direction or parallel to the conveying direction of the strip material, taking along the first end, until the strip has a length sufficient to form a loop.

As a result, the strip material is pulled through the first clamping point in the conveying direction and a tensile force acts on the strip material so that it is conveyed out of the supply of strip material or removed from the supply reel of strip material until the strip has a length sufficient for loop formation. The band material strip is then as a straight strip of tape and can be formed into any loop.

Provision is preferably made for the first end to be moved and positioned in a position outside of the conveying path, below or above the conveying path, with the strip material being conveyed further in the conveying direction via the positioning point until the desired length is reached.

Positioning the first clamping point outside of the conveying path results in the advantage that the strip material, after clamping at the first clamping point, turns over due to the further conveying of the strip material beyond the clamping point and forms a loop in the desired direction. It is ensured that the strip material does not jam while it is being conveyed and that the formation of the loop is blocked.

Provision is preferably made for the band to be severed from the band material before the first or second end is pivoted and/or adjusted.

During the process, the strip material is severed in the direction of the strip material following the second clamping point. The separation preferably takes place after the clamping of the second clamping point, since the strip is then fixed in its desired length, but possibly before pivoting or adjusting, with the advantage shows that both ends are freely movable when panning or adjusting.

Alternatively, it can preferably be provided that the band is severed from the band material after the pivoting and/or the adjustment of the first or second end.

This has the advantage that time can be saved during the process.

It is preferably provided that the strip is conveyed by a shaping pusher, which is advanced from an initial position, taking strip material with it, until a desired end position is reached and forms the strip material into a simple loop as it is advanced, with the first end being clamped before the shaping slide reaches the desired end position, with the shaping slide being pushed back into its starting position after the end position has been reached and the first end being held in a clamped manner for the duration of the entire displacement process, with the second end of the strip being clamped preferably while the shaping slide is being pushed back into the Starting position or after reaching the starting position of the mold slide.

The form slide moves in the direction of the first clamping point, it being possible for the first end to be held in a clamped manner before the form slide is advanced. Alternatively, the first end can only be clamped after the the shaping slide has already been advanced a little. In any case, the clamping takes place before the shaping slide reaches the desired end position, namely the front end position, so that the band material is held clamped at the first end during displacement into the front end position and is thereby fixed. This makes it possible for the shaping slide to shape the strip material into a loop by moving it into the front end position. For this purpose, the forming pusher transports or pushes the strip material past the first clamping point above or below it until the strip forms a simple loop of the desired length.

After the shaping slide has reached the desired end position and the loop has formed, the slide is moved back to its initial position and the second end of the strap is held in a clamped manner. Meanwhile, the first end is held in a clamped manner, namely at least for the entire duration of the entire displacement process. The shifting process of the form slide is only completed when the form slide has reached its starting position again.

The second end is preferably clamped while the mold slide is being pushed back into its initial position. However, the second end can also be clamped only after the starting position has been reached.

The clamped ends can then be adjusted or pivoted for further processing of the simple loop.

The shaping slide can ensure, for example, that the loop is always formed correctly. The feed path can be set to a desired path length, which also sets the length dimension of the loop.

Provision is preferably made for the strip material to be conveyed intermittently.

In this way, a loop can first be completed before further strip material is conveyed.

The invention proposes a device according to claim 13 in order to achieve the object mentioned at the outset.

The strap material that is formed into a loop can be flat strap material, cord, or any other flexible strip material.

A strip of the band material is fed to the piece of textile by means of the conveying device. The strip material is conveyed until the strip is long enough to form a loop.

The strip is clamped at a first clamping point by a first clamping element and at a second clamping point by a second clamping element, with the band material strip provided for loop formation being formed between the clamping points.

The tape material can already be in the form of a simple loop or can be arranged as a straight strip of tape between the clamping elements.

A separating device separates the strip material in the direction of the strip material following the second clamping point, so that the strip is separated and the clamping elements can move freely without being connected to the supply of strip material or being hindered in their movement by the connection.

If the strip is already formed into a simple loop, this can be positioned and fixed directly on the edge of the piece of textile, for example by sewing the loop ends onto the edge. In this case, the clamping elements with the clamping points and the ends lie approximately one above the other.

However, the simple loop can also be processed further, so that a v-shaped or a u-shaped loop is formed by pivoting and/or adjusting the clamping elements or the clamping points.

By pivoting a clamping element to the other clamping element is the simple Loop formed into a U-shaped loop, then preferably one of the clamping points relative to the other clamping point away from this or both clamping points away from each other, in the plane that is spanned by the strip or parallel to this plane, so that the strip is stretched between the clamping elements.

Alternatively, a V-shaped loop is formed from the simple loop in that, after the simple loop has been formed, one of the clamping points is or are adjusted relative to the other clamping point or both clamping points are adjusted relative to one another, in the plane spanned by the strip or parallel to this plane so that the ends of the strips are juxtaposed and the strip forms a v-shape.

If the strip is a straight strip of tape between the clamping elements and no loop has yet been formed, it is brought into a simple loop shape, a V-shaped or a U-shaped loop shape by pivoting or adjusting the clamping elements or the clamping points. When the strip is straight, the clamping elements are initially arranged approximately opposite one another in the conveying direction. To form a simple loop, one of the clamping elements is pivoted about a pivot axis relative to the respective other clamping element, so that the clamping elements, together with the clamping points and the ends, are arranged approximately one above the other. The one between the Clamping elements arranged strip is formed into a simple loop. The simple loop can then be processed further by one of the clamping points being adjusted relative to the other clamping point or both clamping points being adjusted relative to one another, in the plane spanned by the strip or parallel to this plane, so that the ends of the strips are arranged next to each other and the strip forms a v-shape. Alternatively, pivoting can also take place in such a way that the clamping elements, together with the clamping points and the ends, are arranged next to one another or partially overlapping after pivoting, so that a V-shaped loop is formed.

Alternatively, to form a simple loop, the clamping elements are not pivoted, but rather the clamping points are adjusted relative to one another. One of the approximately opposite clamping points in the conveying direction is adjusted relative to the other clamping point in the plane spanned by the strip or parallel to this plane, so that the clamping points together with the ends of the strips are next to each other or at least partially overlapping or one above the other are arranged and the strip forms a V-shape or a simple loop. Both clamping points can also be moved relative to one another.

For pivoting and / or adjusting the clamping elements or the terminal points has the Device on a pivoting device and / or an adjusting device. If one of the clamping elements is pivoted about a pivot axis relative to the other clamping element, so that a U-shaped loop is formed from the simple loop or from the strip of tape that has just been arranged, then the first clamping point or the second clamping point is preferably relative to the other one Terminal point or both terminal points adjusted relative to each other in the plane that is spanned by the strip, so that the U-shaped loop is stretched between the clamping elements.

The formed loop can then be fixed in any way on the edge of the piece of textile.

A positioning device is provided which positions the ends of the strip at the edge of the piece of textile so that they can be fixed exactly to the piece of textile. The positioning device can be, for example, a second pivoting device or adjusting device. Depending on the alignment of the ends of the loop, the first end and the second end can be aligned together transversely to the piece of textile with this positioning device, so that the ends are positioned exactly on the edge of the piece of textile and can be attached thereto. This is necessary, for example, if the ends of the finished loop are arranged away from the edge of the textile piece and are therefore in must be aligned and positioned towards the edge.

A transport device is also provided, which transports the piece of textile with the positioned ends of the strip to a fastening device and the fastening device fastens the ends of the strip to the piece of textile in the correct position. This device can be implemented in a particularly simple and cost-effective manner and can be combined in a compact design. The device makes it possible to form different label formats without having to undertake complex conversion or modification measures. Provision is preferably made for the conveying direction not to be parallel, but preferably directed essentially transversely to the edge of the piece of textile.

The advantage here is that all label formats can be formed from this position and the loops can be fixed to the edge of the textile piece without subsequent turning or pivoting. The term transverse to the conveying direction does not necessarily mean an orientation perpendicular to the edge of the section. It is also to be understood, for example, as oblique-angled orientations.

It is preferably provided that the pivot axis is substantially perpendicular or parallel to that of is aligned by the band material strip spanned plane.

In the event that a simple loop has already been formed and the strip is clamped by the first and the second clamping element at the first and the second clamping point, the ends or the clamping points are arranged approximately one above the other. One of the clamping elements can then be pivoted or pivoted about a pivot axis, which runs essentially parallel to the plane spanned by the strip, relative to the respective other clamping element, so that a U-shaped loop is formed from the simple loop. Pivoting about the parallel pivot axis is particularly advantageous because the clamping elements do not engage in the area in front of the device, for example the transport area of the pieces of textile.

If the strip of band material is arranged straight between the clamping elements and the loop has not yet been formed, the first clamping element or the second clamping element can be swiveled or pivoted about at least one axis and the straight strip is formed into a simple loop. When the strip is straight, the clamping elements are initially arranged approximately opposite one another in the conveying direction.

If one of the clamping elements is pivoted about a pivot axis which is aligned essentially perpendicularly to the plane spanned by the strip, then the clamping elements are next to one another arranged and the strip is formed into a U-shaped loop.

If one of the clamping elements is pivoted about a pivot axis which is aligned essentially parallel to the plane spanned by the strip, the clamping elements are arranged one above the other and the strip is formed into a simple loop.

If, in the event that the band material has just been conveyed out of the band material supply and no loop has yet been formed, one of the clamping elements is first pivoted about a pivot axis which is aligned essentially parallel to the plane spanned by the strip, then a simple loop is formed educated. This clamping element can then be pivoted about a further pivot axis, which is directed essentially perpendicularly to the plane spanned by the strip, so that a U-shaped loop is formed.

The first or second clamping element can be pivoted about a pivot axis which runs parallel or perpendicular to the plane spanned by the strip of band material.

However, it is also possible for one of the clamping elements to be pivoted about a number of pivot axes, for example about a pivot axis which runs essentially perpendicularly and about a pivot axis which runs essentially parallel to the plane spanned by the strip of strip material. Provision is preferably made for the conveying device to be a belt drive with a transport base and for the strip material to be conveyed between the belt of the belt drive and the transport base.

It is preferably provided that the transport base is designed as a shaping slide or that a shaping slide is additionally arranged in the device, with the belt drive and/or the shaping slide being movable from an initial position in the conveying direction of the strip into a working position in which the strip material moves to a simple loop is formed and is movable back into the starting position.

The shaping slide can be moved above or below the first clamping point from a starting position into a working position in which the shaping slide is in a front end position and pushes the strip material past the first clamping point in the conveying direction as it is being advanced from the starting position into the working position until the strip forms a U-shaped loop of the desired length. The belt drive is preferably also moved at least partially in the conveying direction.

Then the mold slide and, if necessary, the belt drive are moved back to their original position. The shaping slide can ensure, for example, that the loop is always formed correctly becomes. The feed path can be set to a desired path length, which also sets the length dimension of the loop.

It is preferably provided that the belt drive is set in a conveying position in which the strip material is pressed by the belt of the belt drive onto the transport base and is conveyed over the transport base, the belt drive preferably being adjustable from the conveying position to a rest position, in which the belt drive releases the belt material.

When the belt drive is in the conveying position, the strip material is pressed against the transport base by the belt of the belt drive and conveyed over this in the conveying direction. Meanwhile, the transport base or a shaping slide serving as a transport base can be moved along with the strip material in the conveying direction, for example in order to form the strip material into a loop. The belt drive can preferably also be adjusted to a rest position in which the belt drive does not touch the strip material. This makes it possible for the strip material to be moved freely in the conveying direction in a simple manner together with the transport base or the shaping slide. This is also advantageous when the strip material is conveyed out of the supply of strip material by the first clamping element or is conveyed away from the coil of strip material, since the strip material can be conveyed without resistance.

Provision is preferably made for the first clamping element to be movable in the conveying direction or parallel to the conveying direction of the strip material, taking along the first end.

As a result, the first clamping element exerts a tensile force on the strip material and conveys it out of the supply of strip material or off the reel of strip material.

It is preferably provided that the first and/or the second clamping element has or is a transport device with which the first end and/or the second end can be moved away from the respective other end.

If the strip is already present in a U-shaped loop, the clamping points and thus the ends can be adjusted and the strip can be stretched between the clamping elements.

Alternatively, if the clamping points are on top of one another and the strip forms a simple loop, a v-shaped loop can be formed by moving them apart.

It is preferably provided that the first and/or the second clamping element is a pair of pliers.

It is preferably provided that the first and / or the second clamping element is a belt drive with a belt drive opposite support element, wherein the strip with its first and / or second clamping point between the belt or the feed roller of the belt drive and the support element is arranged.

The first and/or second clamping element can thus serve as a clamp for clamping the first and/or second clamping point and as an adjusting device for adjusting the clamping points relative to one another. The combination of the two functions in one element is particularly space-saving.

For the same reason it can be provided that the first and/or the second clamping element is an adjustable clamp, the strip being clamped with its first and/or second clamping point between components of the clamp and being adjustable with the clamp.

It is preferably provided that the ends protrude beyond the clamping points and can be fixed to the piece of textile with the protruding area.

The protruding portion of the first and second ends can be fixed to the edge of the textile piece in a simple manner.

The device itself remains unchanged, so that no time-consuming and costly conversion measures are required, but only simple programming of the adjustable computer control must be carried out.

• a conveyor device 3 for the band material 2, with which the band material 2 in the form of a strip 4 in a conveying direction 5 extending parallel to the strip 4, which is not parallel, but is preferably directed essentially transversely to the edge of the piece of textile, in one to one loop formation of sufficient length is conveyed out of a supply of strip material or is conveyed away from a supply reel of strip material,
• a first clamping element 6, with a first end 7 of the strip 4 lying at the front in the conveying direction 5 being clamped at a first clamping point 8 of the strip 4 by the first clamping element 6,
• a second clamping element 9, wherein a second clamping point 10 of the strip 4, which is at a distance from the first clamping point 8, is held in a clamping manner by the second clamping element 9 and the band material strip 4 is formed between the clamping points 8, 10 to form loops,
• a separating device 11 for separating the strip material 2 into a strip, the strip 4 having a second end 12 after the separation and the second clamping point 10 in is arranged in a region of the second end 12,
• The device preferably has a pivoting device, by means of which the first clamping element 6 for loop formation can be pivoted about at least one pivoting axis 21, which is aligned essentially parallel to the plane spanned by the strip 4, relative to the second clamping element 9, and preferably an adjusting device , By means of which the second clamping point 10 relative to the first clamping point 8 in the plane that is spanned by the strip 4 or parallel to this plane is adjustable or adjusted, so that the strip 4 forms a U-shaped loop 1 ', in which the Ends 7.12 are arranged side by side and are positioned and fixable on the textile edge,
• a positioning device that positions the ends 7,12 at the edge of the piece of textile and a transport device that transports the piece of textile with the positioned ends 7,12 of the band to a fastening device and the fastening device fastens the ends 7,12 of the band to the piece of textile in the correct position.

The band material 2, which is formed into a loop 1,1', can be a flat band material, a cord or any other band material.

In figure 1 shows the initial situation in which the strip material 2 is conveyed out of a strip material supply on the right or is conveyed away from a strip supply reel. The strip material 2 is preferably conveyed intermittently. In this way, a loop 1, 1' can always be completed before further strip material 2 is conveyed.

The strip material 2 is conveyed out of the strip material supply in the form of a strip 4 in a conveying direction 5 that extends parallel to the strip 4 and that does not run parallel, preferably essentially transversely, to the edge of the textile piece, in a length sufficient to form a loop or is conveyed away from the strip supply spool . This orientation approximately transverse to the edge region of the piece of textile has the advantage that all label formats can be fixed to the edge of the piece of textile without subsequent turning or swiveling of the loop 1,1'.

figure 1 shows the first clamping element 6, which is designed here as a pair of tongs, the tongs being initially closed and intended to hold the strip material 2 in a clamping manner at the first clamping point 8 at a later point in time.

The conveyor device 3 is, for example, a belt drive 13 with a transport base 14, the transport base 14 being designed as a shaping slide and the strip material 2 is arranged and promoted between the belt of the belt drive 13 and the transport base 14. The direction of rotation of the belt drive is in figure 2 indicated with a movement arrow.

The shape pusher is in accordance with the starting position figure 1 With entrainment of the strip material 2 in the conveying direction 5 of the strip 4 in front (to the left), movable into a working position in figure 3 is shown and in which the forming pusher is in the front desired end position in which the strip material 2 is formed into a simple loop 1 and can be moved back into the starting position (see figure 4 and figure 5 ). The belt drive 13 can also be adjusted at least over part of the feed path together with the shaping slide in the conveying direction 5 in order to bring the strip material 2 to the tongs.

The belt drive 13 can be moved from a conveying position, in which the belt material 2 is pressed against the transport base 14 by the belt of the belt drive 13 and is conveyed over the transport base 14, into a rest position so that the shaping slide can take the strip material 2 with it in the conveying direction 5. in which the belt drive 13 releases the band material 2. The funding position is, for example, in the Figures 1, 2 and 4 shown. figure 3 shows the rest position of the belt drive 13, in which the belt drive 13 does not touch the strip material 2. In this position, the strip material 2 can be moved in the conveying direction 5 together with the shaping slide in a simple manner.

figure 2 shows the device with the tongs open. The pliers are opened before the strip material 2 or the first end 7 reaches the pliers, so that the strip material 2 can be passed through the opening formed by the opened clamping legs 15, 16 of the pliers. Taking the strip material 2 with it, the shaping slide pushes the end 7 of the strip 4 which is at the front in the conveying direction 5 in the direction of the open tongs until the end 7 has been passed through the open tongs to the desired length. Then the pliers close so that the first end 7 of the strip 4 is clamped at the first clamping point 8 by the clamping legs 15, 16 of the pliers (see for example Fig Figure 3 and Figure 4 ).

As Figure 3 and 4 show, the first end 7 is moved and positioned in a position outside the conveying path of the band material, below the conveying path, the band material 2 being conveyed further in the conveying direction 5 via the positioning point until the desired length of the loop 1 is reached. The positioning of the first clamping point 8 outside of the conveying path results in the advantage that the shaping slide can be pushed past the first clamping point 8 together with the strip material 2 .

The shape shifter will, like figure 3 shows, above the first clamping point 8 from the starting position into a working position (the desired end position) and the strip material 2 when being advanced from the starting position into the working position in the conveying direction 5 at the first Terminal point 8 or the first clamping element 6 passed until the strip 4 forms a simple loop 1 of the desired length. The length depends on the feed path of the form slide. Then the mold slide, as in figure 4 shown, moving back until it reaches its starting position ( figure 5 ) has reached. The shaping slide can ensure, for example, that the loop 1 is always formed correctly. The feed path can be set to a desired path length, whereby the length dimension of the loop 1 is also set.

Then the strip 4 is clamped at a second clamping point 10 by the second clamping element 9, such as in FIG figure 4 shown which is spaced from the first nip 8, for example in the vertical direction, and which holds the second end 12 of the strip 4. The ends 7.12 and the terminal points 8.10 are arranged one above the other. The strip material 2 is severed in the direction of the strip material 2 following the second clamping point 10 by means of the severing device 11 and severed from the stored strip material 2 and separated into a strip 4 which is long enough to form the loop 1 (see Fig figure 5 ).

The strip material 2 is preferably separated after clamping at the second clamping point 10 and possibly before the ends 7,12 are pivoted or adjusted, with the advantage that both ends 7,12 are freely movable for pivoting or adjustment. The Separation However, it can also only take place after the pivoting or adjustment. The separating device 11 is symbolically represented in the figures by a pair of scissors.

The strip 4, which has already been formed into a simple loop 1, extends between the first clamping point 8 and the second clamping point 10, as shown in FIG figure 4 shown.

The simple loop 1 can either be fixed to the edge of the piece of textile or further processed into another loop shape, such as the V-shaped loop or U-shaped loop 1'.

If the simple loop 1 is to be processed further into a v-shaped loop, one of the clamping elements 6 or 9 must be adjusted relative to the other clamping element 6 or 9 in the plane spanned by the strip 4 . For this purpose, for example, a clamping element 6 or 9 is designed as a belt drive with a support element opposite the belt drive, the strip 4 being arranged with its clamping point 8 or 10 between the belt of the belt drive and the support element. The clamping element 6 or 9 can thus serve as a clamp for clamping the first or second clamping point 8 or 10 and as an adjusting device for adjusting the clamping point 8 or 10 . From the simple loop 1 with ends 7,12 arranged one above the other, a v-shaped loop is formed in this way juxtaposed ends 7,12 formed. the loop can then be fixed to the piece of textile. This method is not shown in the figures.

If a U-shaped loop 1 'is to be formed from the simple loop 1, the first end 7, as in the Figures 7 to 9 shown, by a pivoting device, not shown, with the first clamping element 6 pivoted about a pivot axis 21, which runs essentially parallel to the plane spanned by the strip of strip material 4, relative to the second end 12 or the second clamping element 9, pivoted about the U-shaped to form loop 1'. Subsequently or at the same time, the second clamping element 9 is adjusted relative to the first clamping element 6 in the plane spanned by the strip 4, so that the U-shaped loop 1' is stretched between the clamping points 8,10. The adjustment is in particular in figure 11 with the end before the adjustment being indicated at 19 indicated in dashed line. The adjustment takes place in the direction of the arrow 20, 20'.

For this purpose, the second clamping element 9 is designed, for example, as a belt drive 17 with a support element 18 opposite the belt drive 17 , the strip 4 being arranged with its second clamping point 10 between the belt of the belt drive 17 and the support element 18 .

The clamping element 9 can thus be used as a clamp for clamping the second clamping point 10 and as an adjusting device for adjusting the clamping points 8:10 serve apart. The combination of the two functions in one element is particularly space-saving. The belt drive 17 serves as a transport device with which the second clamping point 10 can be moved away from the first clamping point 8 parallel to the edge of the piece of textile. As soon as the strip 4 is in the form of a U-shaped loop 1′, the clamping points 8, 10 can be adjusted relative to one another and the loop 1′ can be stretched between the clamping elements 6, 9, as shown in FIG figure 12 is shown.

The ends 7,12 are positioned next to each other and the loop 1' can then be fixed to the piece of textile with the ends 7,12 in any desired manner.

The adjacent ends 7.12 protrude beyond the clamping points 8.10 and can easily be fixed to the piece of textile.

A positioning device that positions the ends 7,12 at the edge of the piece of textile and a transport device that transports the piece of textile with the positioned ends 7,12 of the band to a fastening device and the fastening device that fastens the ends 7,12 of the band to the piece of textile in the correct position not shown in the figures.

The method and the device can be implemented in a particularly simple and cost-effective manner and can be combined and carried out in a compact device. This eliminates the need for costly modifications or conversions conventional methods and devices have to be carried out if a changeover is to be made from one label format to another label format during production. With the present method and the device, it is sufficient to program the provided adjustable computer control for the functional and movement sequences accordingly, so that the desired method steps that are required for the respective label format are carried out.
