ABSTRACT:
A process and apparatus forms and removes piles of sheets transported along a horizontal transport path to a lower-lying transverse removal path in which a pair of removal conveyors engage the end faces of the pile. The removal conveyors are spaced to substantially correspond to the length of the pile, for engaging the edges of the pile during removal transverse to the transport path. A gripper is mounted to move along the higher-lying feed transport path and to engage the leading edge of the pile. The gripper moves along the transport path until the trailing edge of the pile falls onto the removal path, whereupon the pile becomes shortened in the transport direction, i.e., between the removal conveyors in the direction transverse to the removal path, due to curvature of the pile. The gripper is than opened to let the leading edge of the pile fall onto the removal path as well, whereupon the pile assumes its full length, the edges of the pile being substantially in surface engagement with the removal conveyors.
