  • This lever 28 is guided in a guide 29 which is rotatably mounted at a nut 30 provided with an internal threading.
  • Nut 30 is threaded upon a spindle 31 and is secured against rotation at the housing 25.
  • a bolt 32 is mounted at the free end of the block 33 sliding between the legs 34a of the lever 34 which define a slide track, so that the shaft 35 is driven in oscillating fashion.
  • the drive shaft 14 carries a gear 36 at its end, this gear 36 meshing with a drive gear 37 driven by any suitable and therefore not particularly illustrated main drive.
  • a disk 38 is rotatably guided in the gear 36, this gear 36 however being arranged eccentrically.
  • the disk 38 carries at one side or face an eccentrically arranged bolt 39 which corresponds to the pin designated by reference character 27 in FIGS. and 6, and at its other side or face a gear 40 arranged coaxially with respect to the disk 38.

  • the point of rotation of the lever pair 8 can be elevationally adjusted by adjusting the adjustment nut 13.
  • the feed length can be changed by altering the amplitude of the oscillatory movement of the feed rollers, that is to say, as mentioned by displacing the nut 30 along the spindle 31.
  • the balance or rocker 4 at its end secured to the rod 7 is raised by the latter by lifting or raising the piston 10.
  • the feed roll 3 is raised.

  • the balance or rocker 4 at the bolt 1% Upon contact of the balance or rocker 4 at the bolt 1% the latter is pushed downwardly against the angle lever 19. If the compartments 22a and 23a are pressurized, then the pistons 22 and 23 assume the position depicted in FIG. 2.
  • FIGS. 3 and 4 corresponds to that of FIGS. 1 and 2 with exception that the control disk is not seated directly at the drive shaft 14 rather upon a hollow shaft 49 guided thereby and driven through the agency of a speed reduction drive or transmission 48. It is further to be understood that the corresponding components of FIGS. 3 and 4 have been designated with the same reference numerals as have been employed in FIGS. 1 and 2.
  • control disk 15 is not subdivided as wasthe case for the embodiment of FIGS. 1 and 2 into two sections 115a and 15b which each extend through the region of 180, rather the section 15a during its action upon the roller 9, as described, when there is carried out the feed of the workpiece, extends only over a region of 90, whereas the section 15b extends through a region of 270.
