A machine for tapering the ends of lengths of glass fibre composite pipe is disclosed. The machine includes an enclosing cabinet, the cabinet comprising a bulkhead, the bulkhead having a rearward surface and a forward surface, the bulkhead also being provided with an opening therethrough. A first motor is mounted for rotation of a shaft within the cabinet, the shaft extending through the bulkhead opening. Grinder means are rotated by the first motor shaft within the cabinet, the grinder means being positioned forwardly of the bulkhead forward surface to taper an end of a length of glass fibre composite pipe. Stationary mandrel means are mounted in spaced relationship to the grinder means upon the forward surface of the bulkhead, the mandrel means being at least partially within the cabinet to guide the end of the glass fibre composite pipe toward the grinder means. The grinder means and the mandrel means each have a longitudinal axis, the axis of the mandrel means being angularly offset from the axis of the grinder means. Vacuum system means are associated with the cabinet to prevent escape of glass fibre composite dust resulting from the tapering operations. The vacuum system means comprises an inlet positioned near the grinding means to attract glass fibre composite particles and dust resulting from glass fibre composite pipe end tapering operations. |
