Abstract
A tire repairing apparatus includes: a tire support portion rotatably supporting a pneumatic tire; and an application mechanism configured to apply an additive that has a softening effect, to a tread portion of the pneumatic tire supported by the tire support portion, thereby causing the additive to permeate into the tread portion.
Claims13
A tire processing apparatus comprising:
- a support supporting a tire;
- and
- an applicator configured to soften a rubber component of a tread portion of the tire by applying a softening agent having a softening effect that softens the tread portion and causing the softening agent to permeate into the tread portion, wherein
- the support supports the tire in such a manner that the tire can rotate in a circumferential direction of the tire,
- the tire processing apparatus further comprises a motor that rotates the tire in the circumferential direction,
- the applicator includes a contact member that applies the softening agent by coming in contact with a part of an outer peripheral surface of the tread portion when the tire is rotated in the circumferential direction by the motor, and
- wherein the applicator includes a presser configured to press a contact surface of the contact member against the tread portion.

A tire repairing apparatus comprising:
- an idle rotator configured to idle-rotate a tire mounted on a vehicle;
- and
- an applicator configured to soften a rubber component of a tread portion of the tire by applying a softening agent having a softening effect that softens the tread portion to the tread portion of the tire rotated by the idle rotator and causing the softening agent to permeate into the tread portion, wherein
- the support supports the tire in such a manner that the tire can rotate in a circumferential direction of the tire,
- the tire processing apparatus further comprises a motor that rotates the tire in the circumferential direction,
- the applicator includes a contact member that applies the softening agent by coming in contact with a part of an outer peripheral surface of the tread portion when the tire is rotated in the circumferential direction by the motor, and
- wherein the applicator includes a presser configured to press a contact surface of the contact member against the tread portion.
4 more elements
A tire repairing method to restore a hardened tread portion of a tire, the tire repairing method comprising:
- using a support to support the tire in such a manner that the tire can rotate in a circumferential direction of the tire;
- imparting a rotational driving force to the tire, thereby rotating the tire in the circumferential direction of the tire;
- and
- softening a rubber component of a tread portion of a tire after vulcanizing molding by applying a softening agent having a softening effect to the tread portion and causing the softening agent to permeate the tread portion,
- wherein the softening agent is applied with an applicator to an entire region of an outer peripheral surface of the tread portion by causing a contact member holding the softening agent to come in contact with a part of the outer peripheral surface of the tread portion of the tire that is rotated, and
- wherein the applicator includes a presser configured to press a contact surface of the contact member against the tread portion.
3 more elements
A tire manufacturing method comprising:
- using a support to support the tire in such a manner that the tire can rotate in a circumferential direction of the tire;
- imparting a rotational driving force to the tire, thereby rotating the tire in the circumferential direction of the tire;
- and
- softening a rubber component of a tread portion of a tire after vulcanizing molding by applying a softening agent having a softening effect to the tread portion and causing the softening agent to permeate the tread portion,
- wherein the softening agent is applied with an applicator to an entire region of an outer peripheral surface of the tread portion by causing a contact member holding the softening agent to come in contact with a part of the outer peripheral surface of the tread portion of the tire that is rotated, and
- wherein the applicator includes a presser configured to press a contact surface of the contact member against the tread portion.
