ABSTRACT:
A device for applying pressure to a stack of flat items such as sheets, cards, plates or the like, which device is primarily intended for use in an apparatus which feeds items from the stack for further processing. The device provides a constant pressure on the stack, regardless of whether the stack is in full or depleted condition, and, in this way, the device substantially reduces the possibility of malfunctioning by way of two items being fed at once. The device includes a slide member which is linearly movable in a housing, a main weight movable with respect to the slide member, and a roller. The slide member, main weight and roller are operatively coupled together so that the slide member will be urged in the feeding direction under constant force.
