Combined primary and secondary tire shears

摘要

A tire-shearing machine capable of varying the size of tire chunks segmented. A primary shear segments a tire, along a longitudinal axis, into a plurality of longitudinal strips and feeds the strips into a secondary shear. The secondary shear segments, along an axis perpendicular to the longitudinal axis, each of the longitudinal strips into a plurality of chunks. The speed of each of the shears is controlled independently of the other, and on-the-fly, to allow producing tire chunks to a desired size.
