A rasp hub assembly.

摘要

A rasp hub assembly for use in a tire buffing machine is disclosed. The hub assembly includes two end plates (30), and a set of tire rasp blades (20) and spacers (10) arranged in alternating circumferential rows. The blades and spacers have conforming nonplanar elongated bodies, with the blades nested with adjacent spacers. The resulting rasp hub assembly allows the use of an even or odd number of rasp blades in each row, and provides various benefits further described in the specification.
