Definitions

  • the invention relates to a method for producing a shoe, in which at least one upper part is connected to a sole or midsole via a handmade edge seam, for which matching holes are provided in the parts to be connected for pulling through the thread and in which the thread passes through each hole and along the one outside of the seam each twice, but only on the other outside of the seam.
  • Shoes manufactured by such a method are mostly relatively light and simple footwear.
  • the edge of the upper part is preferably bent outwards so that it overlaps in the edge region on the sole or midsole.
  • the holes in the upper part and sole needed for the production of the seam are usually already made before the seam is formed when the sole is being formed or the upper part is punched or cut. It is customary for a shoe of the type mentioned at the outset to pass the thread or the other suture material through the holes to form a so-called backstitch seam.
  • the thread is guided on one seam side with stitches reaching over two holes (pre-stitches) and on the other seam side in the backstitch to the hole skipped during the pre-stitch and pulled back to the other seam side, so that there are two stitches offset by the distance between the holes run.
  • the required thread length must be determined before the sewing work begins and that this entire thread length must be pulled through the holes to form the stitches mentioned, at the start of the seam, so that the free thread length decreases with increasing seam length. It is usually worked with excess lengths when twisting to avoid denominations in the course of the seam. The remaining twine after the seam is finished is lost.
  • GB 1 497 946 A has proposed a device for making a seam in prefabricated holes in the sole and upper part of a shoe, in which each stitch of the sewing needle must be triggered by a foot switch after the parts are aligned with their holes on the needle were.
  • the object of the invention is to eliminate the disadvantages mentioned with simple means and to provide a method for producing a shoe in which the threading of larger lengths of thread through the holes is avoided in the production of the seam, for the seam only the thread length actually required is consumed and in which a faster and more uniform production is possible than with the backstitch seam.
  • the invention consists in that the seam is designed as a crochet seam, in which stitch loops are formed on one seam side from each hole to the next hole, the twine is simply brought up from the previous hole and into the other seam side the hole is inserted, is led back through the same hole from the stitch loop back to the next hole and in which the two thread pieces forming the stitch are passed through the stitch loop brought up from the previous hole.
  • a crochet-like tool can be used for the production of the seam, in which only the needle part with the hook has to be passed through the holes and pulled out again after the same side of the hole, so that there is the possibility of one Ergonomically favorable handle to attach.
  • the thread runs from hole to hole on each seam side. The end result is a seam similar to a quilted seam.
  • the thread After each stitch, the thread can be tightened evenly and firmly, and the thread, which has an even tension, cannot slip back. It is sewn directly from the bobbin, so that the previously necessary cutting of the thread can be omitted in advance.
  • a seam can be produced at least half faster than with the previous technology, whereby since there is no need to pull through, the danger of discolouration of the thread is avoided with dyed leather and a beautiful, uniform seam is obtained. Working with the new tool is easier than before.
  • the seam can be made from top to bottom-outside as well as from outside to inside as required.
  • Sole 1 and upper leather 2 of a shoe 3 are connected by a handmade edge seam 4.
  • the upper leather 2 is bent outwards in the contact area, which is by no means the only embodiment, and, like the sole 1, has through-holes 5 which correspond to the sole and the upper leather.
  • a thread 6 or other suture material is used to produce the seam.
  • a backstitch is carried out with a needle over two successive holes in order to fix the thread end.
  • a stitch 7 reaching to the next hole is formed on the one outside of the seam.
  • a crochet-like tool 8 with barb 9 and ergonomically favorable handle, not shown, is inserted in the manner shown in Fig.
