Definitions

  • the innovation relates to a work piece guide device, in particular a folding device for the appropriate folding of a piping strip for producing a pocket opening without flap with means for determining the length of the seam to be sewn on a downstream sewing machine.
  • two-needle sewing machines are used to produce piped pocket interventions, which are equipped with knives for slitting the pocket opening and for making the V-shaped incisions at the ends thereof.
  • Such a sewing machine is preceded by a folding device for the appropriate preparation of the piping strip.
  • the length of the seam to be sewn is determined in simple manufacture by marking the beginning and end of the seam on the fabric. The seamstress can thus sew up the folded piping strip exactly in a known manner, whereby she must slow down the sewing speed towards the end of the seam so that she can pay particular attention to the correct reaching of the seam end marking.
  • a partially automated sewing system with an upstream folding device is also known, by means of which seams are sewn to piped pocket interventions with a flap at the optimum sewing speed without human intervention on the sewing process can be.
  • the passage of the rear edge of the flap between the folding device and the sewing point is detected by means of a reflex light barrier and then a preset stitch counter is activated, which counts the relatively small number of stitches to be sewn to the end of the seam and then automatically stops the sewing machine causes.
  • the invention is based on the technical problem of designing a generic work piece guiding device in such a way that, in cooperation with a stitch counter, the exact seam length determination - in particular the exact length of the last seam section - is also possible when no scannable edge on the work piece, e.g. B. a flap on a pocket opening is available.
  • the reference number 1 denotes a known folding device for piping strips, in which the piping strips are appropriately shaped as they pass along appropriately shaped sheets, e.g. B. U-shaped, is folded.
  • the folding device with the appropriately labeled inlet and outlet ends is followed by a commercially available two-needle sewing machine, which is equipped with a knife that reciprocates between the needles in the vertical direction and with knives for the V-shaped incisions at the seam ends Pocket openings to be able to manufacture.
  • the folding device is either attached to the machine base plate or pivotally attached to the head of the sewing machine.
  • the grommet 2 of the folding device is surmounted in the area of its outlet by a holding plate 3, to which the transmitter 4 and receiver 5 of a transmitted light barrier are attached.
  • the guide tubes 8 and 8 ' are fixedly attached laterally along the spout 2.
  • a beam emitted by the transmitter 4 can strike the receiver 5 through holes in the walls of the spout 2 (FIG 2), provided there is no longer a piping strip in the outlet area of the spout 2.
  • the conventional folding tongue 6 located there does not hinder the proper functioning of the light barrier 4, 5, which can be achieved with known means by appropriate beam bundling the feed elements of the sewing machine are pulled through the grommet 2 of the folding device and the light beam from the light barrier 4, 5 is first interrupted, however, as soon as the rear end of the piping strip has passed the light barrier, the beam from the transmitter 4 can hit the receiver 5 unhindered in the usual way by means of an electrical signal, a not shown, adjustable elect Ronic stitch counter of known design activated. The same is set to the number of stitches that experience has shown that need to be sewn to the end of the seam. The end of the seam can therefore be controlled automatically at the optimum sewing speed, whereupon the sewing machine - again using known means - is switched off without human intervention.
  • the grommet 2 has a cutout in its central area, through which (FIG. 4) a contact scale 7 is visible, which is provided with a graduation in millimeters.
  • the seamstress pushes the piping strip into the folding device until the rear edge of it lies against a predetermined number of millimeters. As a result, the length of the pocket opening to be sewn is precisely predetermined.
  • markings of any design can be provided so that the seamstress has easily reproducible values as a basis for work.
  • pocket interventions without flap can be produced very precisely with reasonable effort, since the disturbing influences that occur with the folding device according to the innovation with means for determining the seam length can only have a minor effect and are kept within acceptable tolerance limits.
  • the reason for this lies in the fact that the number of stitches to be counted by the stitch counter is relatively small. It only corresponds to the short sewing distance between the light barrier at the outlet of the folding device and the needles of the sewing machine minus the amount by which the piping strips protrude beyond the seam end. On such a short sewing distance, interference such as B. different transport speed of the sewing material, etc., no longer have a detrimental effect. ;
  • the innovation is not limited to the described embodiment of a folding device. Rather, it is also possible to equip other work piece guiding devices according to the innovation, for. B. zipper feeds or other devices upstream of a sewing machine for guiding and / or shaping preferably strip-shaped material.
