An apparatus for applying a binding material to the edge of a leg opening in a pair of unfinished men's briefs during the manufacturing thereof. The apparatus includes a holding fixture for receiving and holding the pair of men's briefs before the crotch is sewn such that the edge of the leg opening is stretched longitudinally. A conveyor conveys the holding fixture to a staging mechanism for engaging and positioning the edge of the leg opening while the brief is conveyed in the holding fixture. A sewing apparatus disposed adjacent the staging mechanism sews the binding material to the edges of the leg openings as the holding fixture is conveyed through the sewing apparatus. A trimmer disposed adjacent the output side of the staging mechanism trims the binding material after it is applied to the leg opening.

11247012

An apparatus for sewing two fabric panels together along the edges thereof. The apparatus includes a combining fixture for holding the panels such that the edges to be joined hang freely in the combining fixture. A staging mechanism engages the edges of the panels to be joined and disposes the edges in overlapping relationship with one another. A sewing apparatus is insertable into the combining fixture for sewing the edges of the panels together while the panels are held in the combining fixture. Finally, the apparatus includes means for movably mounting the sewing apparatus for reciprocal movement between a retracted position and an extended position with respect to the combining fixture.

11247503

An apparatus for forming the crotch in a garment having a front panel and a back panel which are joined at respective ends thereof to form the crotch. A holding fixture engages the front and back panels adjacent to the ends to be joined. A first positioning apparatus positions the ends of the front and back panel in their respective grippers. A second positioning apparatus aligns the edges of the front and back panels with respect to one another. After positioning the front and back panels in their respective grippers, the holding fixture positions the ends of the panels in override flapping relationship. A sewing apparatus is insertable into the holding fixture for sewing the ends of the panel together while the panels are held in the holding fixture.

11247005

A combining and binding conveyor system which combines a first fabric piece and a second fabric piece to form a combined fabric piece, such as a men's brief and applies binding to the fabric piece. The apparatus includes an unique combining fixture for receiving and securing the first fabric piece, the second fabric piece, and the combined fabric piece. A conveyor transports the combining fixture to at least one sewing machine work station having means for operating on the first and second fabric pieces. A transfer station removes the combining fixture from the conveyor when the operations are completed and places the fabric piece on an unique binding fixture for engaging, positioning and securing the fabric piece. The conveyor transports the binding fixture to at least one sewing machine work station for operating on the fabric piece while the same is being held by the binding fixture.
