One of the fi rst commercial continuous sheet splicers has been developed for polystyrene foam thermoforming lines. The supplier, Irwin Research & Development Inc., Yakima, Wash., claims the splicer reduces changeover time and improves productivity. The automatic system has a rotary unwind system (from either Irwin or the customer) that picks up the roll and rotates it into the feeding nip. The next roll is also picked up and spliced automatically to the fi rst roll with no stoppage of the forming line. Both the expiring roll and the new roll are cut and joined with PS-based tape. Irwin is working with a major thermoformer to test and commercialize the technology. Tel: (509) 248-0194 . www.irwinresearch.com
