PCT No. PCT/GB94/02416 Sec. 371 Date May 3, 1996 Sec. 102(e) Date May 3, 1996 PCT Filed Nov. 3, 1994 PCT Pub. No. WO95/12561 PCT Pub. Date May 11, 1995A sheet counter has a blade (13) for insertion between adjacent sheets of a stack thereof, and a pin (15) which orbits around the blade to transfer sheets from one side of the blade to the other. A carrier (37) defines three axes disposed in a generally triangular arrangement, the pin (15) being mounted on one of the axes, and the carrier being coupled to a crank (36) about another axis. A link (42) is pivoted at one end to the carrier (37) and at its other end to a fixed part of the counter. As the pin (15) orbits around the blade (13) on rotation of crank (36), the blade is oscillated about an axis adjacent the edge inserted furthest into the sheet stack by a crank (30) and connecting rod (31), driven synchronously with crank (36). Suction is applied in a timed manner to a hole (45) in the blade (13), to assist the separation of the sheets one at a time, before the transfer thereof to the other side of the blade by pin (15).
