  • Roll supporting slide cutter assembly incorporating a traversable cutter tab and in particular capable of being supported within a carton enclosure associated with a wrap material roll
    Patent number: 7000520
    Abstract: A slide cutter assembly for use in sectioning lengths of a packaging material drawn from a roll. The device includes an elongated and shaped body. A first roll supporting portion is located at a first end of said body and a second roll supporting portion is likewise located at a second end of the body. A cutter assembly extends from a selected lengthwise extending edge of the body and upon which an unwound length of the packaging material comes into contact. The cutter assembly incorporates a traversable blade for sectioning from the roll the length of packaging material. The roll of packaging typically comes in a generally elongated and three-dimensional shaped packaging, the cutter device being constructed so that it may be supported within an interior defined by the packaging and upon first mounting the roll between the first and second roll supporting portions.
