Abstract

Two bars (5, 6) against the drum grip the opposite edges of the sheet. The first bar (5) is released while the second allows reception of a sheet edge when the drum (1) is stopped in a definite angular position. The release mechanism incorporates two arms (22) bearing against the drum end faces and moving the first bar clear of the drum. A manual control (14) then turns the drum to the desired angular position, without moving the first bar. The latter can be held in place by springs (20, 21) bearing against the drum shaft (2) via a component (17) rotating freely in relation to the latter. The arms can be coupled to the manual control, so that after moving the bar clear further movement of the control rotates the drum by the desired amount.
