ABSTRACT:
A slitter slits a wide web into narrow strips by at least one slitting blade mounted on a shaft member which extends in the transverse direction of the wide web while the wide web is fed in the longitudinal direction thereof. The slitter is provided with a slitting width changing system which has a slitting blade holder which holds the slitting blade and is fitted on the shaft member to be rotatable about the shaft member between a released position in which it can be slid along the shaft member in the longitudinal direction of the shaft member and a locked position in which it is fixed to the shaft member not to slide along the shaft member. A slitting blade shift mechanism rotates the slitting blade holder to the released position, slides it along the shaft member to a position determined according to a desired slitting width, and rotates it to the locked position.
