ABSTRACT:
Successive stacks of flexible paper sheets are supplied by the conveyors of a feeding unit in a first direction and along a first horizontal path onto a succession of vertically movable sections of a horizontal table while the sections dwell in their upper positions. The sections are thereupon lowered simultaneously to the level of a second horizontal path wherein a pusher advances the lowered stack in a second direction at right angles to the first direction and along the second horizontal path into the range of two belt conveyors forming part of a removing unit. The sections of the table are disposed one behind the other, as considered in the second direction, and are raised individually back to their upper positions as soon as the pusher advances an article therebeyond. A supporting member assists the sections in supporting an oncoming article in the first path during advancement of such article to a position above the sections of the table.
