Electrostatic pinning makes a clean cut.A new blown film winder from Addex Inc., Stoughton Stoughton (stō`tən), town (1990 pop. 26,777), Norfolk co., E Mass.; founded 1637, inc. 1726. A largely residential town, it was the site of shoe and textile industries in the 1800s. , Mass., uses a cutover (communications, networking) cutover - /cut-ov*/ Switching from an old (hardware and/or software) system to a replacement system, covering the overlap from when the new system is live until the old system has been shut down. with a serrated serrated /ser·rat·ed/ (ser´at-ed) having a sawlike edge. serrated (ser´āted), adj having a jagged or notched edge; saw-toothed. knife that comes up out of a long slot in the lay-on drum and shoots sideways, making a clean cut. The patented drum creates electrostatic charge Noun 1. electrostatic charge - the electric charge at rest on the surface of an insulated body (which establishes and adjacent electrostatic field) electric charge, charge - the quantity of unbalanced electricity in a body (either positive or negative) and for just a few seconds to hold the film firmly in place while it's being cut. The static charge and straight cut "eliminates any possible fold-over of the film at the beginning of the roll," Addex notes. Another advantage of cutting and pinning on the lay-on drum is to allow reverse winding simply by rethreading the web the other way around the roll. Addex built the first winder with the new cutover last year and is building the second now. Tel: (781) 344-5766 * PTDirect: 274WX |
