Abstract
A placket sewing machine attaches a placket patch to a fabric part of a garment in overlying relation to form a multiple layer placket assembly. The placket sewing machine includes a base defining a working surface of the sewing machine. A reciprocating needle chuck has first and second needle openings formed in a staggered forward and rearward arrangement. First and second sewing needles are positioned within respective needle openings of the chuck. The sewing needles are adapted for carrying respective ends of thread into and through the overlaid placket patch and fabric part to form first and second parallel lines of stitches in the placket assembly. The first line of stitches extends a greater distance along the length of the overlaid placket patch and fabric part than the second line of stitches. A sewing motor is operatively connected to the needle chuck for actuating the chuck during operation of the sewing machine. A fabric cutter is located downstream of and centrally disposed between the first and second sewing needles for cutting the overlaid placket patch and fabric part after sewing.
