Abstract
Slide fastener coupling elements are continuously manufactured from a molded strip of coupling element blanks at a speed which is substantially the same as the speed at which the molded strip is produced on a die wheel. The strip of coupling element blanks, as it is withdrawn from the die wheel, is folded about its longitudinal axis into a U-shape while the strip is being heated, and then is heated by hot air before it is shaped into slide fastener coupling elements of a finalized shape as they are heat-set. Then, the coupling elements thus formed are cooled and discharged at a speed equal to the peripheral speed of the die wheel.
