Device for feeding single paper sheets from a pile |
摘要 |
Feeding device for feeding paper sheets from a pile, particularly in offset printing machines. The device has a driving mechanism, the operation of which is controlled by three sets of two cams in precise intervals according to the program of operation of the printing machine. All control mechanisms have their operation motions designed separately in such manner, that each mechanism is controlled by one set of two cams. The advantage of the said feeding device consists in that the control mechanism perform precise operations in accordance with the program of operation even at high printing speeds, because they are controlled bilaterally by the set of two cams and double rollers without employing spring elements to cause cam followers to remain in contact with cam surfaces.
