Abstract

The metal strip dispensing machine has a continuous thickness measuring gauge which delivers thickness data signals to a processing device which controls the delivery of the strip. The system also operates the mechanism which rejects the sub standard parts of the strip, partic. parts which are too thick or too thin. When these portions are indicated by the thickness monitoring devices, the drive for unwinding the strip is stopped. This stopping time is controlled so that the strip is stopped in the correct position in relation to the strip cutter.
