Reinforced metal slitter body having insert pockets

A metal slitter body comprising:

• a cylindrical body portion having a rotation axis (AR) extending through a center thereof and defining a direction of rotation (DR) thereabout;
• a plurality of cutting body portions extending outwardly from the cylindrical body portion;
• opposing first and second body side surfaces;
• and
• a body peripheral surface extending therebetween;
• the slitter body having a unitary one-piece construction and being devoid of screw holes;
• a width direction is defined parallel with the rotation axis (AR);
• an outward radial direction is defined from the rotation axis (AR) towards the body peripheral surface;
• an inward radial direction is defined opposite to the outward radial direction;
• a tangential direction extends perpendicular to the inward and outward radial directions;
• an imaginary bisecting plane (P) is defined as extending perpendicular to the rotation axis (AR) and through the center of the plurality of cutting body portions;
• each of the plurality of cutting body portions comprising:
• a cutting body portion width CBW which is measurable along the width direction and from the first body side surface to the second body side surface;
• and
• an insert pocket configured for resilient clamping;
• each insert pocket comprising:
• an insert receiving slot;
• a first clamping jaw located on one side of the insert receiving slot;
• a second clamping jaw being smaller than the first clamping jaw and located on an opposite side of the insert receiving slot to the first clamping jaw;
• and
• a slot end connecting the first and second clamping jaws;
• the slitter body further comprises a reinforcement portion adjoining the cylindrical body;
• the slitter body, along the reinforcement portion, having a reinforcement portion width RW;
• the reinforcement portion width is greater than the cutting body portion width CBW;
• characterized in that:
• in a side view of the slitter body, the reinforcement portion defines a circular contour;
• and
• in each of the plurality of cutting body portions, the reinforcement portion extends in the outward radial direction (DO) past the inward-most point of the slot end, adjacent to the second clamping jaw.
