Abstract
An apparatus for processing hook and eye fasteners includes a tape feeding mechanism for advancing cloth tape, having hooks or eyes sewn thereon, a predetermined distance through the apparatus. An ultrasonic heat sealing assembly forms a double row of aligned heat sealed stitches on the tape leaving a short section unstitched to form a flap, and a cutting mechanism cuts the tape between the double row of heat sealed stitches, thereby forming individual cloth tape fastener sections having heat sealed edges with an opened unsealed section for insertion of the garment.
Claims10
An apparatus for processing hook and eye fastener tapes, comprising a base, motor means mounted on said base, tape feeding means for incrementally advancing said tape on said base to a sealing station and then to a cutting station, ultrasonic heat sealing means mounted on said base at said sealing station for forming a double row of heat sealed stitches on said tape, each of said rows comprising a line of spaced heat sealed stitches, cutting means mounted on said base at said cutting station for cutting said tape into individual sections, with said cutting means disposed to cut said tape between said double row of heat sealed stitches, thereby forming individual tape sections having edges closed by respective lines of spaced heat sealed stitches, control means for controlling said tape feeding means, said ultrasonic heat sealing means and said cutting means for operation in a timed relationship, and driving connection means connecting said motor means and said control means.
A process for providing hook and eye fastener tapes comprising the steps of incrementally advancing a cloth tape having hook or eye fasteners attached thereon along a base to a sealing station and then to a cutting station, forming at said sealing station a spaced double row of heat sealed stitches on said tape between said hookes or eyes, with each row comprising a line of spaced heat sealed stitches, and cutting said cloth tapes between said double row of heat sealed stitches at said cutting station, thereby providing cloth tape sections having edges sealed by respective lines of spaced heat sealed stitches.
