Vorrichtung und Verfahren zum Schneiden von Wellenpappenkartons

摘要

An apparatus and method for slitting a stack (15) of folded corrugated paperboard boxes utilizes a thin slitting blade (46) mounted for continuous movement through a slitting station and defining a vertical slitting plane. A stack supporting table (26) straddles the slitting blade (46) to support a stack (15) of boxes in a stand-by position above the blade (46). Adjustable upstream and downstream squaring devices (34, 35) are operative to square and center the stack (15) in the cutting plane and a vertically reciprocable ram (66) operates to move the stack (15) and the supporting table (26) downwardly past the blade (46) against a table biasing force to slit the stack (15) into two half-size stacks (47). The squaring devices (34, 35) are operable to re-square the slit half-size (47) prior to conveyance out of the slitting station. The slitting run of the continuous blade (46) operates in a rigid blade holder (66) which is adjustable to compensate for blade wear and to maintain the cutting edge of the blade (46) in a fixed plane.
