Abstract
An auxiliary-pile carrier in a pile lift of a sheet-processing machine is disclosed. The pile lift has a main-pile lifting unit and an auxiliary-pile lifting unit. The auxiliary pile is supported on a pile board having grooves formed in an upper surface thereof. The auxiliary pile carrier comprises auxiliary-pile carrier elements for carrying an auxiliary pile, the carrier elements each having a free end; forward cross-members for supporting the free end of each of the carrier elements; rear cross-members for supporting the carrier elements; the carrier elements are configured so as to allow a rod-like insertion thereof in the grooves formed in the upper surface of the pile board carrying the auxiliary pile, such that the carrier elements are aligned parallel to the grooves; the carrier elements are in the form of chains each having a plurality of links; the links are configured such that the chains are non-flexible in one direction beyond a substantially straight alignment of the links; the rear cross-member is a rotatable shaft with chain wheels rigidly disposed thereon; the chain wheels mesh with the chains and drive the chains.
