  • Patent number: 4343421
    Abstract: An apparatus for feeding fabric in a tensionless and distortion free manner to a fabric treating device. The fabric feeding apparatus comprises a loop forming station, a feeding station and an operator-collector station. The loop forming station continuously forms a tensionless loop of fabric by a pair of driven puller rolls, caused to activate by a signal from a photoelectric combination. The loop of fabric is sequentially fed to a feeding station by the controlled movement of a pin clamping assembly. The movement of the pin clamping assembly causes the photoelectric combination to send a signal activating the puller rolls to reform a tensionless loop. This sequence of pin clamping assembly movement and loop formation causes fabric to be continuously fed in a tensionless and distortion free manner to a fabric treating device.
