Black Clawson Converting Machinery LLC, 315/598-7121, fax: 315/593-0396, www.blkclawson.com
This new Core Waste Reduction System is said to reduce core waste at the unwind/splicer by minimizing the amount of material left on the expiring roll's core. Material remains on the expiring core after the splicing operation is complete, but a minimal amount of material is left.

The winder marking applicator places a tape on the moving web at full speed. The marking detector identifies the marking tape and automatically starts the splice to ensure only a small amount of waste remains on the core.
