ABSTRACT:
The device herein described comprises a feed roller 12 rotated by a motor 16 and disposed before the presser foot 9 at right angles to the feed advance direction of the workpiece. Individually and selectively acting against the feed roller 12 are two pressure backing rollers 19, 20 each of which engages a respective piece of ribbon-like trimmings to push it against the feed roller which carries out the pulling thereof. The pressure backing rollers 19, 20 are supported by a swinging plate which is caused to oscillate upon the action of a fluid-operated cylinder 30 in order to make the backing rollers selectively engage with the feed roller 12 and therefore selectively feed said ribbon-like trimmings under the pressure foot 9.
