Bra slider automat

Welding of a tape loop onto a bra slider using ultrasonic technology. To ensure the bra slider is always optimally centred on the bra strap and to prevent sideways movement, a small loop of tape is fixed on the slider, which in a subsequent operation is attached to the strap by sewing.

The complete manufacturing cycle is fully automatic:

The slider is fed from a container and positioned. A piece of tape is cut from a roll and inserted between the centre and outer slider bars then the tape is formed into a loop around the outer bar. Next the welding takes place on the top and bottom of the outer bar and the slider with the attached loop is ejected into a box.
