Abstract

A slitter and readily removable head includes a drive housing and an idle housing projecting from a base with the arbors for the slitting knives extending between the housings. The lower arbor is journaled in vertically movable blocks with a jack system in the base thus moving the lower arbor. The idle housing and arbors are movable on the base as a unit away from the drive housing so that the idle housing and arbors may readily be removed and replaced. The lower arbor journal block of the idle housing includes a T-slot socket engageable with one or more jacks at a certain horizontal position so that arbors of different length may be employed. The idle housing and arbors forming the removable head contain no gearing, jacks, jack drive connections or fluid or electrical lines requiring connection or disconnection. A turntable may be employed to move the disconnected head to a storage or retooling location. An overhead crane may also be employed to remove or replace the head from or to the storage or tooling location. The slitter includes a horizontally movable actuator with locating pins for quick assembly.
