Abstract
A sewing machine has a movable feed member for feeding articles to a stitch-applying station, and a trimmer for cutting chains of stitches which dangle from articles on the outfeed side of the stitch-applying station. The feed member and trimmer are driven from the same drive shaft. The trimmer drive includes a swinging crank which is connected to a rotary cam by a one-way clutch, one-way clutches which support the rotary cam and permit it to rotate only in the direction it is driven by the crank, and a rocker arm which has one end driven by the cam and another end drivingly connected to the trimmer.
