  • the automatic feeding is preferably carried out with the aid of suitable suction or Blow nozzles that draw in the feed device toward the stop end 131 can generate, so that an inserted workpiece quickly in the correct position is brought to the feeder 113.
  • the sewing material 21 then lies with a corresponding curvature 157 over the folding blade 125, as can be seen in particular from FIG. 31.
  • the folding device is from above 135 with the clamp bar 139 open by means of the vertical movement device 155 lowered to a position shown in FIG. 33. In this position it can be seen that the sewing material 21 is already in the area of the folding device 135 is folded.
  • the sewing material 21 is gripped in two stages by means of clamp bars 139 and folded.
  • clamp bars 139 it is easy Clamps already generated in that in the pneumatic cylinder 145 to both Chambers the same pressure is applied. Due to the smaller printing area in In the chamber in which the connecting rod 147 is located, the piston becomes together moved out of the pneumatic cylinder 145 with the connecting rod 147 and the articulated lever 150 pivots clockwise.
  • the folding device 135 is then turned over the axis 154 pivoted by substantially 90 °, so that the material 21 in the Position is shifted, as shown in Figure 34, so in an essentially horizontal position, which also corresponds to the sewing position. In this position the sewing material part by means of the arm 17 of the insertion device 9 around the center point 27 Clamping device 23 pivoted.
  • the device according to the invention is controlled such that the insertion device 9 a signal from the corresponding clamp device 23 in good time is transmitted that it is ready to receive another workpiece.
  • the device 1 and essentially constant sewing performance of the sewing devices 3 will always be one constant order of assembly of the clamping devices 23 of the preferably result in seven sewing devices 3.
  • the clamp device 23 closes the Clamp elements and conveys the material 21 together with the clamp elements 49 and 50 in the sewing position, such as in Figures 11 and 12 shown.
  • the buttonhole sewing machine starts the buttonhole on its lower one Sewing end d. H.
  • the sewing machine carriage 92 moves from the sewing device 3 way perpendicular to the slide rail 35.
  • the separate slide rail section 35 ' is thus also moved and the pin 79 moves along the Recess 83 to the outside.
  • the sewing device 3 sews the eyelet of the buttonhole 22, one executes corresponding pivoting movement, which is synchronized by the slide rail 35 ' is involved. Due to the pivoting movement, the pin 79 is both pivoted in one direction as well as in the other, which is caused by the expanded Section 85 in the connecting element 81 is made possible. After that the sewing machine carriage 92 moves back and the pin 79 moves back into the recess 83.
  • the actuators 74 within the U-shaped rail 45 are located. This moves to its lower position, as shown in Figure 9, and the upper movable clamp pliers 71 and 72 respectively raised at the same time and the clamp elements 49 and 50 opened. Because of of the dead weight, the sewing material 21 falls down onto the depositing device 15. This turns and conveys the sewing material to a slide or a stop device, For example, a bar that surrounds the material 21 on the circumference directs outwards and the sewing material in the area of the feed station 109, for example falls down in a container attached there. After filling the container can this is gripped by the operator and to the next processing station to be brought.
