Device for detecting the position of an object in a printing machine includes detectors responding to temperature variations

摘要

The device comprises detectors (1,9) responding to temperature variations. The disposition of an object (2) is determined by a contact detector responding to temperature conditions. A signal is produced by heat exchange between the object and the detector. The object is in touching connection with one detector (1) and not touching the other detector (9). The detectors are connected to the same control mechanism (13).
