Abstract

Improved device for supporting a tire assembly in the reconstruction phase of the tread of the same tire by means of a preformed tread strip, comprising a rim that circumferentially supports said tire assembly whose outer peripheral surface, appropriately prepared, it is completely surrounded by the preformed tread strip, after the interposition of a suitable joining means between said tread strip and the facing surface of the tire, and by a protective envelope that surrounds externally and is adhered to the aforementioned one. The tread strip and the sides of the tire and extends up to near the heels of the expressed pneumatic assembly, characterized in that said rim is constituted by two coaxial tubular elements, of which a first element is axially inserted in the second element, whose first and second each element has circumferentially coupling, freely coupled and complementary to each other in the introduction of the first element in the second element, provided with a plurality of grooves aligned in groups according to planes perpendicular to the axis of said first and second element, whose first and second second element are retainable and unlockable to each other by a partial rotation in one direction or another of a disk that is housed in one of the said groups of grooves and further characterized by the fact that said first and second element present externally and circumferentially two crowns that develop symmetrically with respect to a plane perpendicular to the axis of the rim, whose crown has the surfaces turned inwardly of said rim configured so as to cover the outside of the tire beads and partially the sides thereof when they are retained between yes those elements, whose surfaces present so two seats, one for each crown, which run parallel to the aforementioned plane of symmetry, in whose seats are accommodated jointly several other compression rings for the retention with adhesion and hermetically of the aforementioned protective envelope against the sides of the tire.
