Abstract
Sheet-feeding apparatus comprises gripper bars carried on chains driven by sprockets wherein the sprockets are caused to perform predetermined angular displacements, alternating with periods of immobility, an additional angular feed movement being imparted at the start of each period of immobility in order to bring the sheets up against e.g. registering stops. This is especially applicable to a platen press such as that described in Specification 972,416 wherein sheets are picked up at one station, and processed at another, movable stops being provided at each station for registration of the sheets, and the additional feed movement bringing the sheets against the stops (Fig. 1, not shown). The details of the mechanism are illustrated in Fig. 2 wherein a conveyer chain 28 is driven by sprockets 27 mounted on a shaft 26 which is in turn driven in one direction only by a toothed quadrant (not shown). A cam 29 is fixed to the shaft 26 and a locking roller 30 carried on a rocker 31 is periodically forced into a notch 32 on the cam 29, this function being controlled by a cam 33 via cam roller 38, lever 34, link 36 and pin 52 the link 36 is acted on by a spring 37 which ensures that roller 38 presses against cam 33 the rocker 31 is pivoted at 39 on a lever 40 which is concentric of shaft 26 and normally bears against an adjustable stop 41. In action, the cam 37 rotates continuously when the cam roller 38 bears on the smallest radius 44 of cam 33, the linkage keeps locking roller 30 out of cam 29, allowing shaft 26 to rotate freely (Fig. 7, not shown)-this corresponds to movement of a sheet from pick-up to processing stations. Ramp 45 on the cam 33 then causes the roller 30 to drop into the notch in cam 29 immobilizing the shaft 26, Fig. 6 a further gentle rise in the cam from point 48 then causes link 36 to further act on rocker 31, but since this rocker is now fixed with respect to the cam 29 the entire rocker 31 and lever 40 assembly rotates slightly against action of spring 43 and causes shaft 26 fixed to lever 40 to have a correspondingly slight feed movement (Fig. 8, not shown). Rise portion 47 of cam 33 then locks the apparatus during the processing step, before the cycle recommences.
