ABSTRACT:
In handling machines, in particular punching machines, operating in discrete steps, for sheets of paper or similar objects, a warping, waving or wrinkling of the sheets occurs during the deceleration movements of the sheets ahead of the delivery station. These deformations are smoothed by the hold-down device according to the invention, which consists of a circulating perforated endless belt, to which an underpressure is applied from below. There is also synchronization between the feed movement of the sheets and the movement of the endless belt.
