<p>A sheet carrying apparatus for use in a sheet processing machine characterized by a continuously moving belt for transporting a sheet from a sheet receiving station, a pressing member coacting with the belt to ensure nipping of a leading edge of a sheet between the pressing member and belt as the sheet is received at the sheet receiving station, and a device for shifting the pressure member between an advanced position engaging the leading edge of the sheet in the sheet receiving station and a retracted position which is clear of the leading edge of the sheet as it is received on the belt. Preferably, the pressure member is a roller mounted on an end of a lever which pivots on an axle and the axle is provided with pinion gears at each end which are engaged on spaced rack gears with the shifting device including an actuator such as a pneumatic cylinder engaging one end of the axle and a guide for each end of the axle so that the axle moves in a linear path.</p> |
