A toothed tooling mounts to the top die plate above an anvil on the centre die plate both of which ride on posts held by the lower die plate. The toothed tooling comprises multiple blades each with multiple replaceable toothed inserts are held in a cartridge arrangement. The anvil receives brake plates from a separately supported plate feed mechanism with greatly reduced reciprocating mass. The complete die set can be set up on the bench and inserted ready to use in any style of press where the press ram contacts the upper die plate. ## Claims ### Claim 1 An apparatus for texturing the surface of a brake plate, comprising: an independent and free-standing die set for use within a press, the die set having: a base die plate attachable to the press, the base die plate having a series of fixed posts extending upward therefrom; a centre die plate mounted above the base die plate on the posts and movable thereon, the centre die plate having an anvil portion for receiving a brake plate to be textured; an upper die plate mounted above the centre die plate on the posts and movable thereon, the upper die plate having a tooling assembly with a plurality of oppositely acting blades located above the anvil portion; and opposing cam blocks mounted below the upper die plate adjacent the oppositely acting blades; all of the plates being arranged in series such that downward force from the press urges the upper die plate into contact with the centre die plate, and the centre die plate downward toward the base die plate, and thereby actuates the cam blocks to drive teeth of the oppositely acting blades across and into the surface of the brake plate on the anvil, thus texturing the surface of the brake plate; wherein the base die plate is the only portion of the die set that attaches to the press. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the plates are spring-biased apart. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the upper die plate has at least one elastomeric shock absorber disposed on an upper surface thereof. ### Claim 4 (depends on 1) The apparatus of claim 1, further comprising a plate feed mechanism engageable with the centre plate, the plate feed mechanism having: a magazine for holding brake plates to be textured; and a reciprocating slide mechanism for pushing brake plates onto the anvil one by one as they descend from the magazine. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein the load of the magazine is supported independently of the die set. ### Claim 6 (depends on 4) The apparatus of claim 4, wherein the plate feed mechanism is detachable from the die set. ### Claim 7 (depends on 4) The apparatus of claim 4, further comprising a pawl for preventing rearward motion of the brake plate. ### Claim 8 (depends on 4) The apparatus of claim 4, wherein the reciprocating slide mechanism has a variable delivery angle. ### Claim 9 (depends on 4) The apparatus of claim 4, wherein the blades are opposingly arranged in the tooling assembly, such that adjacent blades have teeth oriented in opposed directions. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein each blade has at least one cut-out for receiving at least one insert, the insert having: a first end on which is disposed a plurality of cutting teeth; and a second end having a bulbous projection shaped to loosely engage a correspondingly shaped recess in the at least one cut-out. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein the insert when inserted into the cut-out leaves a gap below the bulbous portion. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein the insert is shaped to wedgingly engage the recess to narrow the gap under force of operation in the press. ### Claim 13 (depends on 1) The apparatus of claim 1, wherein the base die plate further comprises opposing riser blocks, and the centre plate further comprises opposing openings directly above the riser blocks, the riser blocks extendable through the openings to contact portions of the cam blocks to actuate the cam blocks as the upper and centre die plates descend. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein each cam block has a vertical motion member and a horizontal blade moving member, the vertical motion member receiving counterforce from the riser blocks, and engaging into motion the horizontal blade moving member. ### Claim 15 (depends on 1) The apparatus of claim 1, wherein the blades are spring-loaded such that each tooth makes a relatively short gouged inscription and a retention hook on the brake plate before retracting and disengaging from the brake plate. ### Claim 16 (depends on 1) The apparatus of claim 1, wherein the die set is mountable in a mechanical, hydraulic or servo type press. ### Claim 17 (depends on 1) The apparatus of claim 1, wherein the upper die plate is spaced away from the centre die plate for permitting removal and re-insertion of the tooling assembly. ### Claim 18 (depends on 1) The apparatus of claim 1, wherein the tooling assembly is mounted to the upper die plate on rails for permitting removal and re-insertion of the tooling assembly. ### Claim 19 (depends on 1) The apparatus of claim 1, further comprising a sensor proximate to the anvil for monitoring the texturing operation of the tooling assembly. ### Claim 20 (depends on 15) The apparatus of claim 15, further comprising a sensor proximate to the anvil for monitoring hook formation.
