Definitions

  • the aforesaid object is achieved by providing an oscillating lever as part of the carrier of the travelling feed grippers which oscillating lever is linked via a connecting rod to a crank wheel.
  • the fulcrum of the oscillating lever is moved in synchronism with the operating cycle of the machine in relationship to the lowering stroke of the travelling feed grippers by means of a control device.
  • the apparatus of the present invention requires very few drive elements compared to known devices. Accordingly, applicants invention provides for simple and inexpensive production and assembly of the sheet feeding means. Furthermore, most of the few moving parts are easily controlled so that an increase in the number of prints per hour can be obtained.
  • crank pin 61 of the connecting rod 41 is located on that part of the crank wheel 42 which faces the oscillating lever 22, that is, on the line connecting the axis of rotation 43 of crank wheel 42 and the attachment point 41' where'the rod 41 is attached to the lever 22.
  • the crank wheel 42 pivots the oscillating lever 22 via the connecting rod'4l about the axis 23 counterclockwise as shown in FIG. 6.
  • the travelling feed grippers 3 move along a path of travel represented by thearc-shaped line 62 having a radius 63.
  • the feed table plate 10 has an arcuate configuration which is matched to this curvature.
