Abstract
A removal tool (10) for a tire removing machine (1), for taking off a tire (7) from a respective wheel rim (6), comprises an elongate body (12) having a first end (12a) which is connectable to a supporting arm (3) and a second, hook-shaped end (12b) for grasping a bead (14) of the tire (7); the second end (12b) of the tool (10) has a fingernail shaped member (13) which is movable from a first operating configuration, where it projects in cantilever fashion from the body (12) to define the hooked shape, to a second operating configuration, where it is tucked in a lateral zone of the body (12), to give the tool (10) a hookless shape, and vice versa.

A removal tool (10) for a tyre removing machine (1), for taking off a tyre (7) from a respective wheel rim (6), comprising an elongate body (12) and having a first end (10a) which is connectable to a supporting arm (3) and a second, hook-shaped end (10b) for grasping a bead (14) of the tyre (7),
- wherein the second end (10b) of the tool (10) has a fingernail (13) which is movable between a first operating configuration, where it projects in cantilever fashion from the tool body (12) to define the hooked shape, and a second operating configuration, where it is tucked in a lateral zone of the tool body (12), to give the tool (10) a hookless shape.
A method for removing a tyre (7) from a corresponding rim (6) of a wheel (5), using a tyre removing machine (1) equipped with a rotary support (4) for the wheel (5), an arm (3) having a first end (3a) which is movably connected to a frame (2), and a removal tool (10) having a first end (10a) which is connected to a second end (3b) of the arm (3), the method comprising the following steps:
- inserting at least a second end (10b) of the tool (10) between an edge (6a) of the rim (6) and a bead (14) of the tyre (7);
- extracting the bead (14) of the tyre (7) from the rim (6);
- rotating the rim (6) about its axis (X) while keeping the arm (3) in a position where the bead (14) of the tyre (7) is extracted from the rim (6), wherein between the step of insertion and the step of extraction, the second end (10b) of the tool (10) is deformed from a second operating configuration, where it is tapered, to a first operating configuration, where it is hook shaped.
