Abstract
Embodiments provide an inner surface coating apparatus capable of uniformly applying a mold release agent to an inner surface of a green tire with a simple configuration. The apparatus includes: a placement table; a spray gun; and a rotation mechanism that rotates the green tire. An injection axis of the spray gun is oriented toward the inner surface so as to be substantially orthogonal to a central portion of the inner surface in a tire axial direction. A first spray pattern has a longitudinal direction, and includes a central portion and end portions. A width of each end portion is smaller than a width of the central portion. The first spray pattern has the longitudinal direction inclined with respect to the tire axial direction.
Claims9
A green tire inner surface coating apparatus, comprising:
- a support mechanism configured to support a green tire;
- a spray gun configured to spray and apply a mold release agent to an inner surface of the green tire;
- and
- a rotation mechanism configured to rotate the green tire relative to the spray gun about a rotation axis of the green tire,
- wherein an injection axis of the spray gun is oriented toward the inner surface of the green tire so as to be substantially orthogonal to a central portion of the inner surface in a tire axial direction,
- a spray pattern of the spray gun has a longitudinal direction that is longer in the tire axial direction than in a tire circumferential direction, and includes a central portion at a center of the longitudinal direction and end portions at both ends of the longitudinal direction,
- a width of each of the end portions is smaller than a width of the central portion, and
- the spray pattern has the longitudinal direction inclined with respect to the tire axial direction.
