Definitions

  • the present invention relates to an apparatus for cutting tires.
  • the present invention consists of an apparatus for cutting tires of the type comprising a tread, sidewalls and heels so as to cut the sidewalls and cut the tread in order to reduce the size of a used tire and to facilitate the subsequent recovery of its components, but also storage and transport.
  • Equipment includes a rotating tire holder which can be operated to detachably hold a tire, a motor arrangement which can be operated to rotate the tire holder, a first cutting arrangement which can be made operating, in use, to separate the sidewall portions of a tire from the tread portion and a second cutting arrangement which can be operated to cut the tread portion of the tire to form a strip.
  • the disadvantage of this embodiment is that the tire is held by its sidewalls and that the cutting of the sidewalls which is carried out on either side of the tread is not always uniform and of good quality.
  • the state of the art describes many devices in which the cutting is ensured by knives penetrating the tire either from the inside and radially, as in the document AU6884371 , either from the outside and transversely on each side as in the documents - DE4200949 -and WO98 / 24607 .
  • These devices include means for holding and positioning of the tire in space and of the means ensuring its rotational drive to obtain the cutting movement.
  • the device WO2015 / 162443 further comprises means which, capable of emitting a laser beam parallel to the axis X'X of rotation of the plate and disposed above the knives, are associated with detector means intervening when the arm is brought together in the direction of the strip tire tread, to signal to the control means that the laser beam is broken by this tread, while the control means comprise timing means delaying the supply of the actuating means acting on the bringing together of the sliders so that the knives only enter the sidewalls of the tire when they are below its tread.
  • the object of the invention is to remedy the aforementioned drawback by proposing an apparatus which cuts the sides in a uniform manner.
  • the device for cutting the tread of a tire to be cut when said tread is separated from its sidewalls, comprises an upper arm and a lower arm, the upper or lower arm carrying one of its ends, a pair of coaxial discs spaced from each other.
