DEFINITION

Classification: 271/158

(under subclass 157) Device provided with at least two supports alternately or alternatively usable for urging a stack toward the sheet-removal position whereby the sheet removing means may function without stopping for replenishment of the stack.

(1) Note. In some devices plural platforms are mounted on continuously-moving chains so that sheets are fed from the topmost stack while a new stack is loaded on the bottom most platform. In other devices, one platform is held temporarily at the sheet-removal zone while another platform is retracted for reloading of a new stack.
