Definitions

  • the standing shaft (38) carries a pinion (44) of a spiroid gear (45), the ring gear (46) of which is firmly connected to a sliding wheel (47), which is ball-bearing-mounted in a known manner, and an inner part with an axle stub (48).
  • This is received by a bore in an arm (30a) of the carrier (30) and can be clamped in place in the axial direction by a screw (49).
  • the carrier (30) is firmly clamped to it by a screw (51) screwed into its upper part, which projects through a slot (52) in the column (2).
  • the lateral position of the pusher wheel (47) can be aligned with the slot (50a) in the throat plate (50).
  • FIG. 6 shows schematically the distances traveled by the needle (13) during stitch formation and the movement of the sewing material caused by the pusher wheel (46) and the roller foot (80) for a predetermined stitch length (S).
  • the needle When the needle is advanced, the needle (13) sticks into the sewing material at a puncture point (Pl), moves with it over its center line (M) according to the distances (nl and n2) to the sewing point P2 out of the sewing material.
  • the pusher wheel (46) and roller foot (80) also shift the sewing material by the same amount (distances r1 and r2).
  • the needle (13) After the needle (13) has left the material to be sewn in point (P2), it moves back outside the material to be sewn (n3 and n4) to its point of penetration (Pl).
  • the slide wheel (46) and roller foot (80) move the sewing material by two distances (r3 and r4).
  • step impulses acting on the stepper motors (23, 42 and 96) drive the oscillation (17), the slide wheel (47) and the roller foot (80) for the joint transport effect on the workpiece.
