ABSTRACT:
An arbor slitter for use in a slitting line, the arbor slitter having at least two pairs of cooperating, blade-carrying arbors. The inboard ends of the arbors of each arbor pair are supported by an inboard bearing housing. The inboard bearing housings of the arbor pairs are mounted on a common base having caster means resting upon a smooth upper surface of a portion of the slitter frame. The base by virtue of its caster means is both shiftable and positionable along this upper surface of the slitter frame so that each arbor pair can be shifted between a working position and a set-up position. The slitter frame has an outboard bearing housing movable thereon into and out of engagement with the outboard ends of the arbors of each arbor pair when in the working position.
