Abstract
Sensor including a non-contact proximity sensor, proportional change detector system and a sample gate. The machine logic program of the Automatic Sewing System generates a signal which enables the sample gate, at given times during the work cycle. The sample gate also receives a signal indicating fabric discontinuities which is generated by the sensor element. When such input signals are present, at the sample gate, an output is generated thereby to overcome the fabric discontinuities problem.
