The present invention regards a device for assembling and/or disassembling a support ring (SR) within or from a tyre (T), such device including a base, a column or pillar rising from said base and a grip and release group and/or an extraction group.
Claims19
A device for assembling a support ring within a tire comprising:
- a base;
- a column rising from said base;
- a support arm mounted on said column;
- a group for gripping and releasing a support ring, wherein said group for gripping and releasing is articulated to said support arm in order to be angularly movable with respect thereto, wherein said group for gripping and releasing comprises:
- two engagement ends for engaging respective portions within a central hole of said support ring;
- and
- an actuator for approaching and moving apart said engagement ends along a direction of elongation-shortening between a first engagement position, wherein said group is able to stretch the support ring along said direction so as to impart to said support ring a substantially elongated configuration, and a second release position for the support ring,
- wherein the device further comprises a tensioning apparatus configured to enlarge a central hole delimited by the tire in order to facilitate an insertion of the support ring, wherein said tensioning apparatus comprises at least one rope, at least one constrain component supported at a respective end of the rope, and a traction component of the rope.

A device for disassembling a support ring from a tire comprising:
- a base;
- a column rising from said base;
- a group of extraction for extracting the support ring from the tire, said group of extraction comprising:
- an actuator articulated to said column so as to be angularly movable with respect to said column, wherein said actuator comprises a constrain end;
- and at least one belt component supported at the constrain end of said actuator and configured to be wrapped around or to enclose a portion of the support ring, so as to be able to drag the support ring out of an inner channel of the tire,
- wherein said actuator comprises a stem, said stem being movable relative to a respective cylinder, said cylinder being articulated to said column and wherein said constrain end comprises a free end of said stem.
