Abstract
The device according to the invention comprises a passive guiding assembly and a correction device, acting in combination to offer a regular fold before the stitching station. The passive assembly comprises two elements of which one is placed inside the other in the form of a U during formation of the fold. The upper and lower faces of the inner element are plane and horizontal, the lower face being in the working plane of the stitching station. The recess between the two elements allows passage of the fabric. The correction device comprises a device for detecting the presence of the fabric placed under the inner element and an active guiding assembly. The active guiding assembly abuts on the fabric and ensures transverse displacement thereof as a function of the instructions given by the detection device.
