Abstract
A fin mill machine for forming electrically conductive strip stock into corrugated fin material includes a form roller for forming corrugations in the strip stock, which is at an electrical common. A detector detects when the strip stock wraps up around the form roller. The detector includes an electrical circuit having a source connected to a load by a probe. The probe is positioned adjacent the form roller to contact the strip stock when the strip stock wraps up around the form roller such that the electrical circuit has an effective load different than the load. A controller is operable with the detector to monitor the effective load of the electrical circuit. The controller disables the form roller when the effective load of the electrical circuit is indicative of the probe contacting the strip stock.
