The bag closing machine head is equipped with continuous (roll) feeder and sewing needle for the feeding system. The high-speed operation is most suitable for over-tape closure in an automatic bagging line or over-tape (crepe tape) closure on model heat sealers.

Bags are held firmly by feeding chains between bag inserting position and thread-cutting (or over-tape cutting) position, until they are finally closed. Double thread chain stitch with one each needle and looper. Double thread chain stitch, makes tight closures.
