| Zusammenfassung: | The roller (10) has a reference sensor (32) arranged on a side, where the roller is turned to a conveying side. An evaluation unit (30) is formed such that a switching signal is provided from a difference signal between capacitive sensor and reference sensor signals when an object (28) is conveyed by the roller. The reference sensor is arranged fixedly at an axis and close to an inner side of a circulating external cylinder of the roller. Capacitive sensors (36, 38) are arranged one behind the other along a longitudinal direction of the roller. |
