Abstract
The present invention aims to provide a technique that prints characters and patterns clearly onto a tire surface without complicated operations. A tire printing device of the present invention includes a printer head that ejects and applies a coating material onto a tire surface, a widthwise moving unit that moves the printer head along the width direction of the tire, a radial moving unit that moves the printer head along the radical direction of the tire, and a swinging unit that swings the printer head around the axis along the circumferential direction of the tire.
Claims2
A method for printing onto a tire surface by ejecting and applying a coating material from a printer head to the rotating tire surface, wherein
- during the printing, the printer head is swung around an axis along a circumferential direction of the tire while the printer head is moved along a width direction and the radial direction of the tire so as to maintain a constant distance and posture of the printer head with respect to the tire surface,
- wherein the printing onto the tire surface by the printer head is performed under a state that the tire is mounted on a rim and an internal pressure is applied to the tire mounted on the rim.
