  • Patent number: 4339118
    Abstract: A cloth spreading apparatus for use with an automatic cloth cutting machine. The apparatus is used in conjunction with a movable cutting surface which conveys cloth to a cutting station. The apparatus includes a spreader frame which moves on rollers along track surfaces adjacent the cloth laying surface to deposit cloth on the stationary surface. To provide this movement the spreader includes a direct current motor with an output coupled to the rollers. The motor speed of rotation is monitored by control circuitry including a tachometer.Mounted to the spreader is a cloth feed carriage which includes a cloth feed motor. The relative speed of the drive motor and cloth feed motor are controlled by feedback circuitry coupled to a drive and feed tachometer. The angle of cloth deposition onto the cutting surface is monitored by a feeler gauge. Whenever this angle deviates from an optimum value the speed of the cloth feed motor is automatically adjusted by circuitry coupled to the cloth roll motor.
