Abstract
A tire removing machine that comprises a lateral bead extractor formed by an arm that oscillates about a fixed vertical pivot or supports a bead extractor flap and by means for the actuation of the oscillating arm. The actuation means comprise an L-shaped lever that is pivoted about the fixed vertical pivot and has one arm that abuts against a stroke limiter on the oscillating arm and another arm that is provided with a cam follower roller, and an eccentric cam that slidingly engages the other arm of the L-shaped lever and is kinematically connected to a source of rotary motion, so that the rotation of the eccentric cam imparts, by means of the L-shaped lever, a controlled oscillating motion to the L-shaped lever.
