ABSTRACT:
An improved method of serging a trouser-fly piece on a serging machine having a trimming cutter is disclosed wherein a continuous trouser-fly blank assembly is fed intermittently into a first feed path extending toward the serging unit at a predetermined angle relative to a path of movement of the trouser-fly piece being advanced by the serging unit. Then the continuous trouser-fly blank assembly is cut into a succession of elongate rectangular trouser-fly pieces each of which is subsequently advanced toward the serging unit along the first feed path. Thereafter, at least a corner of a leading end of the trouser-fly piece is trimmed by the trimming cutter and, substantially at the same time, one curved longitudinal edge of the trouser-fly piece including the trimmed corner is serged with a serge stitching. In this instance, the trouser-fly piece is caused to turn in one direction to move from the first feed path to a second feed path extending parallel to and aligned with the path of movement of the trouser-fly piece being advanced by the serge unit. With this rotational movement of the trouser-fly piece, the trimming cutter accurately traces a substantially arcuate trimming line passing across the corner. The serged trouser-fly piece is automatically discharged from the serging unit.
