Abstract
A device for folding an edge of a fabric for making a single or a double hem. The device includes a pair of cooperating endless, driven bands for conveying the fabric edge through the device. One of the bands cooperates with a fixed rule and is twisted to correspond to the gradual folding of the fabric edge. The speed of one of the bands can be temporarily varied relative to the other so that the trailing edge of the hem is located somewhat inside of an edge of the fabric which extends transversely to the hem.
