Abstract

Abstract A pleating apparatus for automatically producing successive pleats along a length of drapery or curtain material at regular predetermined spacings, including a pleat forming device positioned at a first station for folding a plurality of juxtaposed pleats in the material with a minimum stressing thereof, and a pleat securing device such as a sewing machine positioned at a second station to secure the formed pleats together into a permanent pinch pleat, and including an advancing mechanism to automatically move the formed pleats from the first station or forming area a predetermined distance to the second station or sewing area and thereby regularly space successively formed pinch pleats along the material. The pleat forming device gathers the material ahead of the device to form the pleat so that the material in and beyond the device is not stressed and the spacing between pleats can be adjusted by varying the space between the first and second stations.
