  • Seam detection and control system
    Patent number: 4323786
    Abstract: The invention pertains to apparatus for sensing the presence of a seam in a moving strip of fabric being proccesed, the detection of a seam actuating a control circuit which modifies the fabric processing to accomodate the seam. An optical seam detector determines the rate of movement of the fabric, initiates a electronic counter producing a voltage inversely proportional to the rate of fabric movement. An electronic timer, also initiated by the sensing of the seam, receives and evaluates the velocity determined voltage and produces a timed actuation of the fabric processing apparatus corresponding to the seam arriving at the processing station. The disclosed circuit is capable of actuating two fabric processing stations sequentially arranged in the direction of fabric movement, and the circuitry resets itself upon initial seam detection.
