Title: Belt for calendering
Inventor: SAKUMA NORIO
IPC: D21F3/02
Filed: 2002-04-29
Granted: 2004-11-11
Abstract: The present invention provides a relatively low-cost calendering belt having excellent heat resistance and durability. The calendering belt (10) comprises left and right side portions (20, 20) located at opposites ends in a width direction and a main body portion (30) located at center.
