Definitions

  • the invention relieves the operator of the described, time-consuming handling activity. There is an increase in productivity.
  • the sewing machine is technically very simple.
  • the piece of sewn fabric that is sewn in each case is transported on without the operator's intervention and without the use of any additional conveying devices, and the thread chain between successive pieces of sewing material is cut automatically. Even when the rear edge of each piece of sewing material has passed through about a third of the length of the fabric pusher and the pressure plate from its rear end, the operator can devote himself to preparing the next piece of sewing material. The completion of the sewing process on the previous piece of sewing material and the transfer of the sewn sewing material piece are carried out automatically without the operator having to monitor this in particular and to intervene in order to transport the sewn sewing material piece onward. Further transport of the piece of sewing material after the thread chain has been severed to other processing stations is also possible automatically.
  • the fabric slide extended on one side and the pressure plate elongated on one side cause a tendency of the respective piece of sewing material to move obliquely forward sideways to the cutting device, the thread chain between this sewing material piece and the subsequent sewing material piece being relaxed. As a result, the suction of the thread chain to the cutting device is facilitated.
  • a needle plate 2 is embedded in its working surface 1. This takes on a fabric pusher 3. Furthermore, as seen in the direction V of the material feed, a wedge-shaped projection 2.1 pointing in the same direction is formed on the right long side of the needle plate 2.
  • the free-running section of the attachment 2.1 is separated from the actual needle plate 2 by a slot 4 located in the sewing axis A, into which the sewing needle 5 of the sewing machine engages to form the thread structure or the thread chain F.
  • a pressure plate 6 of a presser foot 7 of the sewing machine which can be raised and lowered, cooperates with the fabric slide 3.
  • a cutting device 8 with an integrated suction device, aligned parallel to the sewing axis A, is arranged along the right long side of the work surface 1.
  • the suction opening 10 of the suction device is aligned at right angles to the feed direction V.
  • the fabric slide 3 and the pressure plate 6 each have an extension 12 or 14 on their side facing away from the cutting device 8 in the direction V of the material feed, so that they extend from the operating side of the sewing machine (below viewed in FIG. 2), extend to the level of the cutting edge 8.1 of the cutting device 8.
  • the plane of the cutting edge 8.1 is at right angles to the feed direction V.
  • the extension 12 or 14 is approximately 20% of the length l u of the fabric slide 3 or the pressure plate 6 which has been customary hitherto.
  • FIGS. 1 and 2 show a finished, sewn piece of sewing material N immediately after the thread structure F has been separated by the cutting edge 8.1 of the cutting device 8.
  • the dash-dotted outline of the rear part of a sewing material piece N also represents that position of the sewing material piece N in the course of the sewing process, from which no more monitoring by the operator is necessary and the operator can concentrate on the preparation of the next piece of sewing material N.
