VORRICHTUNG ZUM ANTRIEB EINES SCHWINGENDEN VORGREIFERS EINER DRUCKMASCHINE.

摘要

The invention concerns a swinging gripper arm of a printing machine which delivers the sheets to the printing cylinder. The swinging arm is driven by a shaft (16) which carries a gear wheel (17) which meshes with an internal toothed gear (14) which meshes with a pinion (13). This pinion is fitted with an eccentric pin (19) attached to a link (12). The other end of the link is pivoted to an oscillating lever (9) which swings about an axis (21). This oscillating lever carries two rollers (10,11) which co-operate with two driving cams (7,8).
