IPC: B26D5/16
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To accurately adjust blade pressure by finely adjusting the blade pressure by using rotation of an eccentric cam. SOLUTION: A blade pressure adjusting member 8 is adjacently arranged to an upper blade installing unit 6, and this is composed of a main body 8a fixed to a support stand 1 by a pair of fixing screws 8b, 8b.
