Line tension roll

A guide to fabric slitting line tension rolls

April 10, 2007 | By Jim Rusczyk, Douglas Goetz

Coil processors have several choices in the rolls they use to put tension on the coil. One of these choices is a pair of nonwoven rolls. They act like sponges in that they remove lubricants, dirt, and metal fines from the metal. Understanding how nonwoven rolls are constructed and how they work can help coil processors extend their service life.

Coated stamping dies

Tooling coating extends die life, reduces die rework

April 10, 2007

Glacier Vandervell's Bearing Group, a division of Dana, manufactures bearing components—bushings and thrust washers—for the automotive industry. It uses about 40 alloys and encounters many abrasion problems in its stamping operations, especially those involving aluminum. Its die coatings were not satisfactory because the heat used to apply the coatings would cause many of its dies to warp. It switched to FortiPhy™, a coating provided by Phygen Inc., and the tools now warp less and last longer.
