Abstract
A method and apparatus for finishing the surface of rubber or synthetic covered rollers (10) is disclosed. As seen in FIG. 3, a rotating hub (16) having a circumferential abrasion band (47) and an adjacent set of rasp blades (20) arranged end-to-end and extending circumferentially about the hub is used to progressively and sequentially removebands of surface material by cutting and then abrading as the hub and roller are rotated and one is moved axially relative to the other.
Claims11
A hub for use in finishing the surface of a roller having a cover comprising:
- a band of gritted surface material extending circumferentially about an axis of revolution of said hub;
- a set of rasp blades extending circumferentially about said axis of revolution, each rasp blade having a plurality of cutting edges;
- and wherein
- said set of rasp blades is located adjacent one side of said band of gritted material whereby when said roller and hub are rotated and one of said rollers and hub is displaced axially of the other, the rasp blades cut and remove surface material of said roller, and said gritted surface thereafter removes material from the surface of said roller in abrading action.
A method of finishing the surface of a roller having a rubber or synthetic cover comprising:
- rotating the roller about its axis;
- engaging the outer surface of the cover of the roller with a hub rotating about its own axis which is parallel to the axis of the roller, wherein the hub includes a circumferential band of abrading material and a set of rasp blades extending end-to-end circumferentially about said hub adjacent said band;
- and
- translating one of said hub and roller longitudinally of its axis to remove a first circumferential band of said surface material from said roller by cutting action of said rasp blades, and immediately thereafter removing a second circumferential band of material from said roller.
