ABSTRACT:
A plurality of individual openings provided in a sheet strip material by a stamping device are passed in succession through a monitoring station positioned adjacent the outlet of the stamping device. As each individual opening is passed through the monitoring station, the monitoring station produces a plurality of voltage signals which identify the progress of each opening through the monitoring station and the progress of the sheet strip material through the stamping device. A controller is provided having an input for receiving the plurality of voltage signals produced as each opening is passed through the monitoring station and an output connected to the stamping device. Within the controller, the plurality of voltage signals identifying the progress of an individual opening through the monitoring station are compared to the plurality of voltage signals identifying the progress of a following opening through the monitoring station. A deviation between the plurality of voltage signal sets identifies a sheet strip material misfeed condition within the stamping device. As soon as a sheet strip material misfeed condition is detected, the controller provides a signal to the stamping device to initiate stoppage of the stamping device.
