Abstract
A coil slitting tool in the form of a rotary serrator knife for use on coil slitting machines includes a plurality of serration undulations disposed on one or more faces about the outer periphery. The rotary serrator knife tool may incorporate a concentrically located bore about an inner diameter for mounting on an arbor and may further incorporate a keyway. The rotary serrator knife may be formed from an assembly having, a central rotary disk about which mount one or more removable inserts including the serration undulation portion. The one or more removable inserts may include serration undulations on one side or two sides and mount substantially to the perimeter of a mounting disk by use of fasteners.
Claims17
A rotary slitting system comprising:
- two or more correspondingly opposed rotary serrator knives, each having
- a disk comprising a substantially flat first surface, and
- a substantially flat opposing second surface joined by
- an outer perimeter surface defined by an outer diameter, and
- one or more replaceable inserts comprising
- a first insert face substantially parallel to the first surface, an insert seat, an outer insert perimeter surface that is smooth,
- a second insert face opposite of and joined to said first insert face by the outer insert perimeter surface, and
- circumferentially spaced serration undulations disposed upon said first insert face forming, in conjunction with said outer insert perimeter surface, a shearing edge of serration profile, the one or more inserts mounted to the outer perimeter surface of the disk,
- wherein the serration undulations of each correspondingly opposed rotary serrator knife are synchronized and opposingly meshed thereto to impart a serrated edge upon material drawn between and in the direction of rotation of the two or more correspondingly opposed rotary serrator knives.
