Abstract
An automatic bead release device for tire removal machines, comprising, for supporting the wheel rim complete with tire, rotary means associated with a frame which supports a bead release disc in contact with the tire just external to the flange of the wheel rim, a shaft parallel to its axis of rotation, on which said frame slides to approach and withdraw from the wheel rim, means for moving said frame along said shaft, and means for lightly inserting said disc below the flange of the wheel rim after it has come into contact with it.
Claims17
An automatic bead release device for tire removal machines, characterised by comprising, for supporting the wheel rim complete with tire, rotary means associated with a frame which supports a bead release disc in contact with the tire just external to the flange of the wheel rim, a shaft parallel to its axis of rotation, on which said frame slides to approach and withdraw from the wheel rim, means for moving said frame along said shaft, and means for lightly inserting said disc below the flange of the wheel rim after it has come into contact with it.
A device as claimed in the preceding claims, characterised by comprising two frames symmetrically disposed on the same shaft, in symmetrically facing positions.
A tire removal machine comprising a base from which there upwardly project rotary means for supporting the wheel rim, and a column carrying at least one tool arranged to interact with the tire bead, characterised in that said tool undergoes movements parallel to the axis of rotation of the wheel rim, and the rotary means supporting the wheel rim undergo translating movements arranged to position the flange of the wheel rim in a fixed zero position relative to the direction of movement of said tool.
