ABSTRACT:
A system for manufacturing curved shirt plackets with buttonholes includes the steps of moving curved placket blanks in sequence from the top of a bundle to a positioning station, positioning the plackets for feeding to a buttonhole sewing machine, intermittently feeding the plackets to a buttonhole sewing machine and turning the plackets as necessary to align the lengths of the buttonholes across the length of the curved placket blanks, and transferring the plackets to a cutting station where they are cut in half and stacked in bundles of buttonhole halves and button halves.
