Definitions

  • 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.
  • 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.
  • 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.
  • U-shaped loops it is also possible to make U-shaped loops.
  • the device has to be expanded for this purpose.
  • a carriage with an adjustment option for the width of the tape and a guide is arranged on the machine frame.
  • 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.

  • Another device is from WO 01/92626 A1 known.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the separation can also only take place after the pivoting or adjustment, which results in the advantage that time can be saved.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • one of the ends can 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.
  • 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.
  • 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.
  • 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.
  • the band is severed from the band material after the pivoting and/or the adjustment of the first or second end.
  • 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 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.
  • 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'.
  • 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.
  • 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'.
  • 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'.
  • 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.
  • 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.
