Abstract: Apparatus for cutting a tire into a number of segmented pieces utilizes a plurality of pairs of shear-cutting blades actuated by a hydraulic cylinder ram. One blade of each pair is affixed to a carriage movable on a track secured to a frame. The other blade of each pair is affixed to the frame. The hydraulic cylinder ram moves the carriage on the track so as to effect a cutting action of the blades, and result in a tire placed within a tire-cutting area defined by the frame being cut into segmented pieces.

Abstract: Apparatus for cutting a tire into segmented pieces utilizes an even multiple of pairs of shear-cutting blades actuated by a hydraulic cylinder ram. The pairs of blades are arranged in radial symmetry, and each pair of blades comprises an upper blade and a lower blade, both of which have a cutting edge defined thereon, such that each pair of blades operates by action of opposed cutting edges. The lower blade of each pair is affixed to a frame, which may be trailer-mounted for mobility. The upper blade of each pair is affixed to a carriage movable on a track secured to the frame, and oriented with the cutting edge disposed at an acute angle relative to the cutting edge of the lower blade. Diametrically opposing upper blades are disposed at corresponding angles, and adjacent upper blades are disposed at different angles from one to the other.
