Abstract
The present invention relates to a tire segmenting device capable of cutting tires into two or more segments, the device including: a cutter for dividing the tire into two or more segments; a positioning device on which the tire is mounted, the positioning device positioning a tire mounted thereon in alignment with the cutter; and a moving device operatively connected to the positioning device; wherein in use, the moving device moves the positioning device between a loading position in which a tire can be loaded and unloaded from the positioning device and a cutting position where the cutter engages the tire and divides the tire into the two or more segments.
Claims20
A tire segmenting device comprising:
- at least one cutter for dividing a tire into two or more segments, said cutter comprising:
- at least one first circumferential blade for separating a crown of said tire from sidewalls of said tire;
- at least one second circumferential blade concentric of said first circumferential blade for separating a bead of said tire from said sidewalls of said tire;
- and at least one radial blade for radially dividing said tire, said first and second circumferential blades and said radial blade each extending from a base plate;
- a positioning device on which said tire is mounted, said positioning device positioning said tire mounted thereon in alignment with said cutter, said positioning device comprising a mounting plate which supports said tire, and an alignment hub extendable through a central hole of said tire mounted on said positioning device in order to position said tire in alignment with said cutter;
- and
- a moving device operatively connected to said positioning device which moves said alignment hub between a retracted position and an extended position, said retracted position being where said alignment hub is located below said mounting plate, said extended position being where at least a portion of said alignment hub extends above said mounting plate;
- wherein said moving device being adapted to move said positioning device between a loading position in which said tire can be loaded and unloaded from said positioning device and a cutting position where said cutter engages said tire and divides said tire into the two or more segments.

A method of segmenting a tire using a tire segmenting device, said method comprising the steps of:
- a) providing a tire segmenting device comprising:
- at least one cutter having at least one first circumferential blade, at least one second circumferential blade concentric of said first circumferential blade, and at least one radial blade;
- a positioning device having a mounting plate, and an alignment hub which;
- and
- a moving device operatively connected to said positioning device;
- b) mounting a tire on said mounting plate of said positioning device which positions said tire mounted thereon in alignment with said cutter;
- c) extending said alignment hub through a central hole of said tire mounted on said mounting plate in order to position said tire in alignment with said cutter;
- d) moving said positioning device and tire mounted thereon into a cutting position where said tire is in engagement with said cutter using said moving device which is operatively connected to said positioning device;
- and
- e) cutting a crown of said tire from sidewalls of said tire using said first circumferential blade, cutting a bead of said tire from said sidewalls of said tire using said second circumferential blade, and dividing said tire into radial segments using said radial blade.

A tire segmenting device comprising:
- at least one cutter for dividing a tire into two or more segments, said cutter comprising:
- at least one first circumferential blade for separating a crown of said tire from sidewalls of said tire;
- at least one second circumferential blade concentric of said first circumferential blade for separating a bead of said tire from said sidewalls of said tire;
- and at least one radial blade for radially dividing said tire;
- a positioning device on which said tire is mounted, said positioning device being configured to position said tire mounted thereon in alignment with said cutter, said position device comprising a mounting plate which supports said tire, and an alignment hub extendable through a central hole of said tire mounted on said positioning device in order to position said tire in alignment with said cutter;
- and
- a moving device operatively connected to said positioning device which moves said alignment hub between a retracted position and an extended position, said retracted position being where said alignment hub is located below said mounting plate, said extended position being where at least a portion of said alignment hub extends above said mounting plate and through at least one hub aperture defined through said mounting plate;
- wherein said moving device being adapted to move said positioning device between a loading position in which said tire can be loaded and unloaded from said positioning device and a cutting position where said cutter engages said tire and divides said tire into the two or more segments;
- wherein said alignment hub is formed from three or more circumferentially spaced apart arms which extend from a base support to form a substantially frustoconical shaped structure.
