Abstract: Tire-buffing system constituted by a robotic arm (1) with angular interpolation movements with the aim of providing a modular machine capable of allowing greater amplitude of movements. The range of the movement is particularly optimized on the part of the scraping tool (5) which is installed at the end of a robotized arm (1). The buffing system is controlled via a control panel including a controller and the robotic arm is provided with at least three articulations (2) (3) (4) and two arms (12) (13) to approach automatically towards a tire to be buffed. Said tire (7) (8) (9) is supported by a rotary mandrel (6) (10) fixed independently of the robotic arm.

Abstract: Tyre-retreading system constituted by a robotized arm with angular interpolation movements with the aim of providing a modular machine capable of allowing greater amplitude of movements on the part of the scraping tool (5) and/or rubber-applying tool (11), which is installed at the end of a robotized arm (1) controlled via a control panel and provided with at least three articulations (2, 3, 4); the tools (5, 11) act on a tyre (7) supported by a mandrel system (6, 10).

Abstract: The present disclosure relates to an arrangement in a tire retreading rolling machine including a structure composed of a lower frame (Q) provided with adjustable feet (P) and one column (C) on one of its vertices. Column (C) has on its outer side a motoreducer set (MR) which rotates a hub (CB) positioned on the column inner side. A bearing (M) held to column (C) supports the hub (CB) shaft, on which the tire to be processed is mounted. The rolling device mounted on the frame (Q) comprises arms (1) with end rolls (2), on which the tire is rested on the wheeling position. The rolls (2) press the new tread against the tire carcass, expelling the air that may have been trapped. The arms (1) are centrally pivoting in transversal gears (3), by the action of cylinders (4), allowing to get rolls (2) closer or farther to/from the new tread applied to the tire carcass.
