The present invention relates particularly to a tire processing apparatus comprising a head that is operable to move about two or more axes at a first end of a swing arm, the head further having a rasp operable to strip rubber particles from a stationary tire for use of the particles as a landscaping mulch. In various embodiments, the apparatus also comprises a head with a circular saw operable to cut a portion of the tire into a livestock trough. The invention also includes a method using the above. The system and method in its various embodiments are particularly adept at processing used tires from mining industry applications.

An apparatus for cutting tires comprises a frame (1), an accommodation zone (2) intended to receive a tire (31) to be cut, lateral holding means (5, 6) for a tire, a detector (4) capable of detecting a central zone of a tire (31), blades (7) mounted to slide between a separated position of disengagement of the tread and a working position in which they penetrate into the sidewall (32) of a tire, and a control (9) ensuring that the blades (7) penetrate into the side walls (32) of the tire (31) only when they are above its tread (33). The lateral holding means (5, 6) comprise a vertically sliding jaw (6) capable of pressing against the bead (34) of a tire (31) and a part (5) with two branches (37) each bearing a wheel (38) capable of coming into contact with an inner surface (35) of the tread (33) of a tire, the jaw (6) and the part (5) being diametrically opposed relative to the inner circumference of a tire. The blades (7), when they are in working position, penetrate into the side walls (32) of a tire (31) received between the two branches (37) so as to stabilize the cutting zone.

A multi-part long knife (10) is provided for cutting rubberized and non-rubberized steel cord, rubber sheets with or without fiber reinforcement, industrial textiles, steel sheets and non-ferrous metals. The multi-part long knife (10) includes an elongated knife carrier (12), on which at least one elongated blade (16), having a cutting edge (18), is held. The knife carrier (12) has a clamping strip (14), which is guided in a recess (22) of the knife carrier (12) in a clamping direction (K). A receptacle (46) for the blade (16) is formed between the knife carrier (12) and the clamping strip (14), which clamping strip (14) is guided in the recess (22). A first clamping surface (50) is formed on the knife carrier (12) and a second clamping surface (52), opposite the first clamping surface (50), is formed on the clamping strip (14), between which the blade (16) can be clamped.

Disclosed is a cutting device and a method for cutting a continuous strip into tire components. The cutting device includes a knife for cutting the continuous strip along a cutting line in a working plane and a feeding assembly with a feeding member for feeding the continuous strip in the working plane to the knife in a feeding direction that intersects with the cutting line at a cutting angle. The feeding member and the knife are rotatable with respect to each other about a rotation axis perpendicular to the working plane for adjusting the cutting angle. The feeding assembly further includes an input member for receiving the continuous strip in an input direction into the cutting device and one or more guide members for guiding the continuous strip from the input member to the feeding member, wherein the input member is placed in line with or substantially in line with the rotation axis.

A block of construction material is fabricated by harvesting a plurality of tread strips from a plurality of tires by, for each tire, removing a tread texture of a tread cap from each tire using a tread removal device while leaving a remaining portion of the tread cap intact with one or more sidewalls and shoulders of each tire, removing the side walls and the entire shoulders from each tire by cutting through the remaining portion of each tread cap, and slicing the remaining portion of each tread cap to produce tread strips. Each strip is preheated, and while maintaining the temperature, stacked onto the gummed previous strips, until a block of desirable size is yielded. Use of fasteners, plates and membranes to maintain the stacked tread strips into a block arrangement is eliminated.

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.

The machine for breaking a part of a tire down into pieces includes a frame and a tire support which is adapted to support a part of the tire. The machine also has a supplying device which is configured to feed the part of the tire to a cutting station which includes a cutting device.
