ABSTRACT:
An overlock sewing machine wherein a thread which breaks between the shuttle and the looping discs is allowed to bypass the loop stripping device and is advanced by the discs toward and against the cutting edge of a knife provided on one leg of the U-shaped thread guide which confines the looping discs. This prevents the discs from convoluting the broken thread onto the shaft which drives the discs.
