Abstract
A thread-cutting mechanism for a sewing machine (2), especially an eyelet-buttonhole sewing machine with a moving blade (12 or 12') and a stationary blade (16). The moving blade travels back and forth in a groove (19) in a plate (1) with an aperture for the needle to pass through while it is producing a stitch. The needle-aperture plate comprises at least a top (11 or 11') and a bottom (10 or 10'). The moving blade is entirely accommodated between the top and the bottom of the plate. The stationary blade is part of the top.
