摘要： In web-fed rotary printing machines having a plurality of operating units arranged one after another, each unit having synchronously driven elements that interact directly or indirectly with the printing-material web, high reliability and short response times are achieved by a torque monitoring device having inputs for signals corresponding to the torque on at least one element of each operating unit. Upon the occurrence of an abrupt torque change on at least one monitored element, the monitoring device generates an output signal associated with a web break.
