Abstract
An apparatus for checking tyres has a support, deformation systems, positioning actuators and a moving member. The deformation systems apply, in operation, compression forces on respective surfaces of a free wall of the tyre to form deformed portions of the free wall. The positioning actuators move the deformation systems towards and away from the surfaces. The moving member sets the tyre in relative rotation with respect to the deformation systems.
Claims21
An apparatus for checking tyres, the apparatus comprising:
- a support on which a tyre is adapted to be rested, a resting wall and a free wall being defined in said tyre, said free wall being arranged at a certain height with respect to said support;
- a first deformation system configured to apply, through physical contact, a compression force on a surface of a first portion of said free wall, to elastically deform said free wall to form a first deformed portion of free wall;
- a first positioning actuator operatively associated with said first deformation system and configured to cause movement of said first deformation system towards and away from said surface of said first portion of free wall of said tyre, said movement having at least one component along a first axis parallel to a rotation axis of said tyre;
- a second deformation system configured to apply, through physical contact, a compression force on a surface of a second portion of said free wall, in order to elastically deform it so as to form a second deformed portion of free wall;
- a second positioning actuator operatively associated with said second deformation system and configured to cause movement of said second deformation system towards and away from said surface of said second portion of free wall of said tyre, said movement having at least one component along a second axis parallel to said rotation axis of said tyre;
- and
- a moving member to set said tyre in relative rotation about said rotation axis with respect to said first deformation system and said second deformation system,
- wherein a first plane passing through said rotation axis of said tyre and said first axis and a second plane passing through said rotation axis of said tyre and said second axis form an angle of 90° to 180°.
