In order to design a sheet feeder with a nonstop-device with stringers suspended at lifting chains and cross bars carried by the stringers for supporting bars that serve as base for a remaining pile, in such a way that the remaining pile, which is on the bars of the nonstop-device, is laterally adjustable, the stringers are seated in longitudinal guideways, extending in direction of lifting, and the cross bars are supported slidable on the stringers transversely to the direction of transport of the sheets and are traversed by means of a motor that is supported transversely to the direction of transport of the sheets, which motor can be actuated in the one or the other direction according to the situation of the side edge of the pile by means of a sensing device that senses at least one upper side edge of the pile. The sensing device may preferably at the same time be co-ordinated to a second motor for straightening the main pile. |
