ABSTRACT:
An edge guiding device is provided for sewing work with several edges extending at angles to each other, and on which parallel seams are to be formed, e.g., collars. The device has an edge ruler which is formed by a central section and two sections controllable independently of the central section, each with a guide face. During the formation of seams which begin or end at inside corners of the collar or work, the edge ruler is moved synchronously with the work displacement. Thereby, e.g., one-piece collars plus collarbands can be securely guided from the start during the formation of the seam sections beginning or ending at the inside corners of the collars. For guiding at a long side of the collar, which is usually curved, the outer sections of the edge ruler are pulled back and only the central section with its arched guide face is used for guiding the work.
