Abstract
An abrading wheel such as a rasp hub for use in tire retreading machines includes two generally circular end, or side, plates with plural spaced mounting pins extending between and coupled to the two spaced plates. Rasp blades arranged in stacks which are arranged end-to-end about the wheel's circular circumference. Disposed between and engaging each pair of adjacent blades is a spacer, which is also attached to the mounting pins. Each spacer is curved lengthwise to match the curvature of the blades and includes plural spaced upper and lower recesses disposed immediately adjacent to its pair of adjacent blades to allow air to freely pass over the entire length of each blade as the hub is rotated at high speed to dissipate heat from the blades during operation for increased blade reliability and longevity.
