Disclosed herein, a tire tread cutting apparatus for cutting a length of a tire tread is described. The tire tread cutting apparatus includes a track having a first track end and a second track end downstream of the first track end. The track includes a plurality of rollers positioned between the first track end and the second track end. The plurality of rollers is configured to facilitate the tire tread along the track. A tire hub is positioned downstream of and adjacent to the second track end. The tire hub is configured to receive a tire casing. The tire casing defines a tire casing circumference along an outer surface of the tire casing. A tread dispenser is positioned upstream of the track and configured to dispense tire tread. The tread dispenser includes a drive roller configured to drive tire tread downstream toward the second track end.

Disruptor device consisting in a frame said frame (F) having a Water Jet system to disaggregate one portion a tread or a sidewall of a tire, an hydraulic power unit, a control cabinet with PLC and control panel, a lower assembly, an upper assembly, an hopper for collection of fragmented materials and a vibrating screen, a group for the forced ventilation system and the air/water separation wherein the upper assembly consists on a frame divided in two identical first half-frame and second half-frame (20b); the upper assembly is supported to the frame (F) by two arms (la, lb); the upper assembly (9) presents a series of rollers (14) and a movable plate (24) positioned on each half-frame (20a, 20b) between two of these rollers (14) and supporting an upper nozzles head (18) supplied by high pressure water through a piping system; the lower assembly (2) presents a set of rollers (15) mounted on a fixed frame (22); in the space between two of rollers (15) scrolls a slide (24) for nozzle-head (21) that supports one or more, left and right, lower nozzles (23) supplied by high pressure water through a piping system.

A water jet splitting machine for waste tires includes a feeding device, a water jet splitting chamber, a waste tire controlling device, a water jet device, and a discharging device. The water jet splitting chamber is disposed beside the feeding device. The waste tire controlling device is disposed on a top of the water jet splitting chamber and has a central line and a claw assembly. The claw assembly is disposed in the water jet splitting chamber and has at least three claw mechanisms. Each one of the at least three claw mechanisms has a claw capable of moving away from the central line along a radial direction. The water jet device is disposed beside the claw assembly of the waste tire controlling device and has a water jet seat having at least one water jet head. The discharging device is disposed beside the water jet splitting chamber.

Systems and methods for downsizing tires are disclosed. An automated downsizing apparatus comprises a cradle, mandrel table, cutting apparatus, and a control unit. A tire mounted on the cradle may be received by the movable and rotatable mandrel table, and positioned for engagement with the cutting apparatus. A user may customize a cutting configuration to be executed by the control unit. The control unit positions the mandrel table and cutting apparatus to remove portions from the tire, according to the cutting configuration. During operation, one or more system parameters may be monitored to determine compliance with the selected configuration, and the automated execution may be manually overridden.

Disclosed are a round knife, a cutting assembly, and a method for cutting tire components wherein the round knife includes a carrier that is rotatable about a rotation axis (X) and a plurality of first edge segments which are arranged to be mounted side-by-side in a circumferential direction (G) about the rotation axis (X) to the carrier to form a circular cutting edge (E) extending concentrically about the rotation axis (X), wherein the segment body is arranged to be spaced apart from the carrier in the radial direction (R) at the center between the first lateral side and the second lateral side.

An apparatus for cutting a whole tire into strips may include a cutting device having a first rotary blade and a second rotary blade. The tire is positioned between the first rotary blade and the second rotary blade, which cut the tire into one or more strips. The apparatus may further include a positioning system operable to orient the tire between a plurality of vertical, horizontal, and intermediate positions, relative to the cutting device. The apparatus may include one or more support rollers. The apparatus may further include a control system that controls the operation of the cutting device and tire positioning system as the tire is cut into strips by the cutting device. The apparatus may include a chipper to cut the tire strips into chips. The apparatus may include a bead peeler to remove the exterior rubber sheath from the wire bead.
