ABSTRACT:
A guide for slotting, scoring, trimming, or like heads mounted in mating relationship in a slotter for scoring a cardboard blank on the fold lines and slotting, timming or the like of the blank between the various flaps so that it may be folded into a box, carton or the like. The guide includes a plate with an arcuate bearing surface which is adapted to ride along the bottom of a peripheral groove having a bottom and sidewalls provided therefor in the heads. The plate portion of the guide is thinner than the groove is wide and has a plurality of recesses in its opposite side faces into which rollers are mounted for rotation off the side centerline thereof. the rollers exert a balanced radial thrust on the sidewalls of the groove aligning the head. At least some of the rollers are preferably eccentrically adjustable about their axis of rotation such that contact can be established and maintained between the rollers and the sidewalls of the groove and the heads are thereby laterally fixed on their respective shafts.
