Abstract: A device for folding at least one edge of a fabric for making a single or a double hem, said fabric edge being passed through shaping means contained in the device. The object of the invention is to provide a folding device, which within a relatively large area with respect to the most common fabrics, is insensitive to variations in thickness of the fabric, whether several fabric edges are to be folded simultaneously or whether transverse seem with considerable thickness occur. This object has been solved by the fact that the shaping means comprises portions of at least one endless, driven band, which is twisted in correspondance with the gradual folding of the fabric edge during the transport thereof through the device and said band being arranged to cooperate with at least one fixed rule arranged in direct connection with at least a part of the band portions.

Abstract: A hemmer intended for making double-folded hems by feeding a fabric edge through the device comprising at least a folding edge, a main bar and a folding rule arranged at a distance above the main bar. The main bar front end being bevelled and designed to fold the fabric edge around the folding rule with the hem edge located between the main bar and the folding bar and in its second, rear part the main bar being designed with an upfolded, longitudinal edge section which partly is arranged to extend along and over the rear longitudinal edge of the folding bar and partly is bevelled at its front section. The hemmer in one embodiment may be adjusted to fold hems of different widths and hems which already have transverse hems.
