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.

Grating is formed from longitudinal members and transverse members that are operatively coupled together. The longitudinal members may be described as bearing members and the transverse members may be described as cross members that extend between the bearing members. The separation system and process of the present disclosure separates an initial grating having an initial grating width into multiple gratings have gratings widths less than the initial grating width. The separation system includes a driven die assembly having opposing dies, each opposing die having knives and spacers which interact to separate the cross members of the grating to create multiple gratings as the same time. The knives may be set up in different configurations in order to create any number of gratings having flush cross members (e.g., flush with the bearing members) and/or overhanging cross members (e.g., hang over the bearing members).

A slitting machine for removing a strip from a sheet of material. The slitting machine has a blade assembly with first and second cutting blades, and a perforating blade arranged between the first and second cutting blades. The first and second cutting blades are arranged to cut the sheet of material to define the strip and the perforating blade is arranged to perforate the sheet of material to define an end of the strip.
