Abstract
One or more workpieces are positioned on the outer surface of a mandril which has a first longitudinal slot oriented in a longitudinal direction. A lift finger is disposed in the first longitudinal slot in a rest position and configured to be lifted out of the first longitudinal slot in a lift position to lift a portion of the workpieces outwardly relative to the outer surface of the mandril. A pinching device is used to pinch the lifted portion of the workpieces, which may be stitched with a stitching device. The mandril is movable in the longitudinal direction to feed the workpieces. The mandril includes a second longitudinal slot for housing a feed roller shaft, which protrudes from the second longitudinal slot to contact the workpieces. The feed roller shaft is rotatable to rotate the workpieces relative to the outer surface of the mandril. An alignment device is provided for alignment the workpieces and stabilizing the workpieces for precise processing.
