Abstract: The present invention provides a tire assembling/disassembling machine, particularly for industrial vehicle wheels, having a support frame (2) delimiting a foreheadt, a back and two sides, a rigid support framework (13) articulated at the back of the support frame (2) according to an articulation axis (12), driving means (15) for angularly lifting/lowering said rigid support framework (13) with respect to said support frame, a self-centering assembly (14) overhangingly carried by said rigid support framework (13) at the foreheadof said support frame (2), whereby its axis of rotation is substantially normal to said articulation axis (12), and bead-releasing means carried by said rigid support framework.

Abstract: A tire assembling-disassembling machine includes a supporting, locking and rotating device for a wheel-rim for a vehicle tired-wheel about the axis of rotation of the wheel, at least one bead releasing assembly provided with a fixed support structure and a pair of supports extendible-retractable in a substantially radial direction with respect to the axis of rotation starting from the fixed support structure and slidingly mounted along guide structure, at least one bead releasing roller carried at one end of a respective extendible-retractable support, driving structure for moving the arms towards and away from each other, a tool for fitting a tire onto the wheel-rim, a controller for radially extending-retracting each support and controllable locking-releasing structure for each support in an extended position thereof, and additional controllable driving structure to effect an additional extension of its respective support when locked in its extended working position by the locking-releasing structure.

Abstract: A rapid tire inflation plant comprising a low pressure high flow inflating gas source, an inflation device, a motor, a compressor driven by said motor and a control circuit arranged to control feed of low pressure inflating gas from said inflating gas source to said compressor and the feed of inflating gas at a relatively high flow and pressure to said inflation device.

Abstract: Method of, and apparatus for, fitting a resilient ring substantially circular in shape into a tire, and removing it therefrom, the method comprising the following steps in sequence: initial deforming of the resilient ring by slightly stretching it along one diameter thereof so as to cause it to change from a circular to an elliptical shape; fitting of the thus deformed ring lengthwise into the light of a tire in which the ring is to be assembled; first releasing of the ring whereby it tends to regain its initial circular shape while remaining engaged in the tire light; final deforming of the resilient ring by stretching it in a radial direction within the tire, and final releasing of the deformable ring whereby it regains its initial circular shape within the tire.

Abstract: Bead releasing and removing head for a tire fitting machine comprising a support frame (2) anchored to the tire fitting machine and supporting at its top at least a bead releasing disk (3) and a bead removing tool (4), having a working tip (7), wherein the removing tool (4) is slidably supported by said head and comprises driving means (5) suitable for displacing it, upon control, so that the working tip (7) is movable between an advanced working position and a withdrawn rest position.

Abstract: A rapid tyre inflation plant comprising a low pressure high flow inflating gas source, an inflation device, a motor, a compressor driven by said motor and a control circuit arranged to control feed of low pressure inflating gas from said inflating gas source to said compressor and the feed of inflating gas at a relatively high flow and pressure to said inflation device.

Abstract: A group for assembling, disassembling and bead releasing of a tire (2) onto and from a wheel-rim (3) supported mounted for rotation about an axis and having at least a carriage or slid (4) displaceably mounted on guides (5) extending parallel to the axis of rotation of the wheel-rim (3), an arm or upright (6) extending in a transverse direction with respect to the said axis of rotation and having one end thereof supported by the slide or carriage (4) and its other end provided with a bead releasing tool (7, 8) that can be arranged so as to have its working front or edge (107, 108) facing towards the same side.
