Abstract

Apparatus for converting a continuous stream of partially overlapping sheets of paper or the like into a succession of stacks has a table which is movable between a first position adjacent the discharge end of a conveyor for the stream of sheets and a second position adjacent a stack removing unit. When in first position, the table is lowered gradually at the rate at which the height of the growing stack on its top increases, and such table is mounted on a reciprocable carriage which further supports a platform adjacent to the table so that the platform can enter the gathering station and take over a growing stack while the fully grown stack on the table is advanced to the removing unit. The table and the platform are provided with conveyors so that a fully grown stack can be transferred from the table onto the removing unit and the conveyor on the platform can transfer a growing stack onto the table when the transfer of the fully grown stack onto the stack removing unit is completed.
