ある。 As shown in FIGS. 3 and 4, the tread winding thickness sensor 7 is mounted on a base 8 supported by the automatic winding device 2, and has two sensors extending in the tire width direction (up and down direction in FIG. 4). slide rail 9a,
9b has been installed. This slide rail 9
A cylinder 10 with a sensor 7a mounted thereon is slidably mounted on the support plate 11, and the support plate 11 is connected to the sensor 7a by a slide drive device 12 (air cylinder) placed on the base 8. It is configured such that the lateral position of 7a can be changed arbitrarily. . That is, the belt-shaped tread W supplied from the extruder is measured by the tread winding thickness sensor 7 and the tread W and the sensor 7a.
The device always maintains the relative position with respect to the winding direction at a position set according to the winding direction, and detects the tread thickness.
次にタイヤTの外周面に、帯状のトレツドWを

に向つて移動する。 In this state, one end of the band-shaped tread W supplied from the extruder is pressed onto the outer circumferential surface of the tire T via the stitching roller 6, and the tire T supported by the tire support device 1 is held constant. rotate at a speed of In this way, as the tread W is being wound, the thickness of the tread W is measured by the tread winding thickness sensor 7, and when a certain set thickness is reached, the forward/reverse drive motor 5 starts rotating in the forward direction. Start. As a result, the automatic winding device 2
As the screw shaft 5a rotates, the guide rail 4
The band-shaped tread W, which moves from one side of the tire width to the other along the widths a and 4b, and at the same time has one end crimped onto the outer peripheral surface of the tire T, is sequentially wrapped in a constant inclination direction and wraps around the tire. Move towards the other side of the width.

出来る効果がある。 There is no need for a worker to stop the winding position each time or return it to the starting position, and therefore,
The winding work can be done efficiently, and there is no need for templates as the winding is done while constantly detecting the winding thickness of the tread.Furthermore, since the winding is done by back-and-forth winding with overlapping layers following the set shape, the number of back-and-forth trips is reduced. At the same time, it is possible to effectively prevent tread separation signals, thereby significantly extending the life of the tire.
