Abstract

A separating apparatus, in which the sheet material is conveyed in stacks via a stack transporting system to the stack holder, comprises first apparatus for effecting selective mechanical manipulation of the stack going through the separation process in case sensors, which check the separation sequence, detect a deviation from the proper separation process. Further sensors may be provided in addition for testing the stack before and during separation as to its shape and/or state of conservation. Taking this information into account, an irregularity occurring during separation can then be combatted by triggering that measure which appears best suitable for automatically eliminating the disturbance of the separation process.
