<p>A machine for forming shoulder straps for ladies garments, of the type having a first tape with a buckle secured to one end and a second (elastic) tape having a ring secured to its end, the two tapes being united by passing the free end of the first tape through the ring and then back through the two slots of the buckle. The machine described is supplied with spools of tape, and with buckles and rings, and performs all the operations needed to produce the strap including sewing of the buckles and rings in place, and the threading and buckling operations, as well as cutting off suitable lengths of the tapes. The means for uniting the first and second tapes comprises a first clamping device for holding the buckle end of the first tape with the buckle disposed substantially perpendicular to the tape, and a second clamping device having a narrow projecting end for holding the free end of the first tape and being suitably dimensioned for inserting this free end through the ring of the second tape, and subsequently into a slot of the buckle. These clamping devices are moved between an initial position in which the free end of the first tape is held horizontally for receiving the ring, and a final position in which the free end has been rotated through 180.degree. and can then be inserted into a slot of the buckle. Bucking means are provided for completing the buckling of the first tape through the second slot of the buckle.</p> |
