Abstract:

An apparatus and method for forming simulated wear patterns and designs in denim pants using laser rays. The apparatus includes an indexable carousel having a plurality of circumferentially spaced pant-supporting mandrels that are sequentially indexable to a plurality of stations located about the carousel, including a loading station, a laser station, and an unloading station. The mandrels each comprise articulated linkage that is selectively actuatable between a retractable condition that permits positioning of a pair of pants onto the mandrel at the loading station and an expanded condition that tautly supports the pants in predetermined position at the laser station such that a laser generated pattern can be formed at predetermined locations on the pants.
