Abstract
This invention uses a unique tubular cutting tool in a method for separating individual cables from the elastomeric body of a cable-type conveyor belt. The tool bores a cylindrical path through the elastomeric body coaxial with the individual longitudinal reinforcement cables. A transverse cut is then made across the belt width which just intersects the cylindrical paths which have been made around the cables. The elastomeric material can then be removed leaving only the cables exposed. The prepared belt end is then ready for application of a mechanical or vulcanized splice. The tubular cutting tool features both circular and axial cutting edges. The tool can be utilized in a hand drill to allow on-site splice preparation of the conveyor belt.
Claims4
A tool for cutting cylindrical cores in rubber comprising:
- a tubular body having an axis of rotation;
- a first annular section of said tubular body with a first co-axial bore therethrough and a sharp circular cutting edge forming one end of said first annular section;
- said first annular section being integrally connected to a second annular section of said tubular body at the end distal said cutting edge, said second annular section having a second bore coaxial with said first bore and separated therefrom by a first tapered shoulder, and a cutting slot extending axially from proximate said first shoulder and including a minority of the periphery of said second annular section, said cutting slot having a cutting edge extending axially along one edge of said cutting slot, a third section of said tubular body integral with said second annular section forming a shaft adaptable for gripping said tool.
