Abstract

In monitoring the machine space of a processing machine during the throughput of workpieces in order to detect workpieces that got stuck, the rear end of a workpiece with reference to the transport direction generates a start signal in the inlet region of the machine space, as well as an end signal in the outlet region thereof by sensors that are connected to a control unit. Beginning with the start signal, the control unit detects a feature that characterizes a theoretical feed travel and generates a release signal if the value of the detected characteristic feature has reached at the time, at which the end signal is generated, a predefined limiting value and not yet exceeded a predefined upper limiting value or if the end signal is generated at a time, at which the value of the detected characteristic feature has reached the predefined limiting value and not yet exceeded the upper limiting value.
