<p>A sitter and readily removable head (14, 15, 16) includes a drive housing (12) and an idle housing (14) projecting from a base (10) with the arbors (15, 16) for the slitting knives extending between the housings (12, 13). The lower arbor (16) is journaled in vertically movable blocks (38, 57) with a jack system (88, 89, 90) in the base (10) thus moving the lower arbor (16). The idle housing (14) and arbors (15, 16) are movable on the base (10) as a unit away from the drive housing (12) so that the idle housing (14) and arbors (15, 16) may readily be removed and replaced. The lower arbor journal block (57) of the idle housing (14) includes a T-slot socket (79) engageable with one or more jacks (88, 89, 90) at a certain horizontal position so that arbors of different length may be employed. The idle housing (14) and arbors (15, 16) forming the removable head contain no gearing, jacks, jack drive connections or fluid or electrical lines requiring connection or disconnection. A turntable (126) may be employed to move the disconnected head (14, 15, 16) to a storage or retooling location. An overhead crane may also be employed to remove or replace the head (14, 15, 16) from or to the storage or tooling location. The slitter includes a horizontally movable actuator (105 with locating pins (109, 110) for quick assembly.</p> |
