Abstract

In some examples, a sheet processing machine includes an at least one pile formation device. The at least one pile formation device is arranged so as to be displaceable at least in an inward-moving direction. The at least one pile formation device includes a plane. The at least one pile formation device is displaceable at least in a vertical direction relative to at least one lower multiple-up separating tool by means of a lifting device. In a temporary storage position, at least the plane is arranged in a vertical direction beneath a plane of the at least one lower multiple-up separating tool.
