Abstract: The machine for breaking a part of a tire down into pieces includes a frame and a tire support which is adapted to support a part of the tire. The machine also has a supplying device which is configured to feed the part of the tire to a cutting station which includes a cutting device. The cutting device has a first blade and a second blade that are pivotable with respect to one another at a fulcrum. At least one of the first and second blades has a concave shape and cooperates with the other blade to keep the part of the tire inside of the blades. The supplying device includes a movable unit which can pivot about a vertical axis between first and second positions.

Abstract: Machine for extracting a cord made of metal material from a sidewall of a tire, being part of the sidewall and defining a support structure of said tire, including: a frame; support means for the tire configured to support said tire resting on one sidewall in a loading zone; a hook for extracting said cord from the sidewall of the tire; means for manipulating said hook, configured to manipulate the hook with respect to the frame in an extraction direction between a position for engagement with said tire in the loading zone and a position for disengagement from said tire and extraction of said cord; a command and control unit to command said means for manipulating the hook,: an element able to move with respect to the frame to detach the cord from the hook when the hook is in position for disengagement; and means for manipulating the movable element, to manipulate the movable element from a first position to a second position to carry out releasing of the cord from the hook.

Abstract: Machine for cutting off the sidewalls of a tire, which comprises, in combination: a frame; connecting means configured to connect the tire in a pre-established position with respect to the frame, in a zone for loading said tire; at least one head equipped with at least one cutting blade for cutting off a sidewall of the tire; manipulation means that act in operation on said tire or on said cutting head in order to allow said cutting blade to be set into relative movement with respect to the tire; means for adjusting the relative position of the blade with respect to the connecting means, which act in operation on said blade or on the connecting means for the tire in order to allow the blade to be positioned such that, during said relative movement, the blade cuts off the sidewall of the tire along its circumference.
