A machine for continuously manufacturing tape strips having at least at one end a portion folded through an aperture of a workpiece is provided. A tape supply section supplies tape to a tape feed unit which is adapted intermittently supply a first predetermined length of tape through an aperture of a workpiece and a second predetermined length of tape not through an aperture. Work pieces are supplied to and received by a workpiece receiving device adapted to hold the workpiece and position the aperture of the workpiece in the tape traveling path. Tape folders operate to fold a tape towards a fusing member positioned above the workpiece. Tape gripping arms further fold a tape into a fusing member. A tape cutter cuts the tape after a second predetermined length of tape is fed from a tape supply section. Tape gripping arms then operate to eject the finished strap from the machine.

Complementary fastener product

A fastener assembly is disclosed which includes a first fastener strip having on at least one side a first fastening surface. Also provided is a second fastener strip having on at least one side a second fastening surface that is complementary to the first fastening surface. The first fastener strip overlies the second fastening surface of the second fastener strip with the first fastening surface not facing the second fastening surface. The first and second fastener strips are releasably connected.

As tape drawer rollers are driven for intermittent rotation, a continuous tape is intermittently fed along a tape traveling path with a leading end portion of the tape inserted through a ring at a tape folding section. When the continuous tape has been fed by a predetermined length, the feeding of the tape is stopped and then the lower end portion of the tape inserted through the ring is bent about the ring by a first bending member. Then a cutting device severs a predetermined length of tape strip off the continuous tape, whereupon the an upper half of the severed tape strip is bent about the ring by a second bending member, thus providing a folded tape strip having a laminate portion. Finally the folded tape strip is discharged out of a machine after part of its laminate portion is fused by a fusing device.

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.
