Zig-Zag Servo Feed Saving Material at InSInkErator

Friday, February 24, 2012
 
The press shop at the Racine, WI manufacturing facility of InSinkErator has added a zig-zag press-feeding system supplied by CWP and Formtek Maine, Clinton, ME. The servo-feed system, rated for stock 18 in. wide by 0.030 in. thick, features a stock reel, straightener and threading tables. A variable-tension brake automatically adjusts brake tension as the coil depletes. Matte-chrome pinch rolls and smooth-chrome straightening rolls on the stock straightener help to shed particles and process critical-finish material used to manufacture parts for the firm’s waste-disposal units. Zig-zag feeds, when used for stamping circular blanks, can result in a 22-percent scrap reduction compared to conventional feeds, say CWP officials; www.cwpcoil.com/. Here’s a short 1-min. video of the system at work.
