Abstract: PROBLEM TO BE SOLVED: To stick a rubber material with a gauge exceeding a gap to a rotary support at high precision and high efficiency by driving to rotate a pair of rollers located near the surface of the rotary support in an opposite direction to each other and supplying the rubber material using the gap formed between the rollers as a roller die. SOLUTION: A pair of rollers 11, 12 are provided near the surface of the toroid-like part 1a of a rotary support 1. These rollers 11, 12 rotate in the opposite direction to each other. In addition, a gap is formed on a segment which is orthogonal with each other rotary center axial lines 11c, 12c and is used as a roller die Dr. Further a kneaded rubber material is supplied to a geared pump 25 and then is extruded from a die 27 as a ribbonlike rubber material with a comparatively thick wall through a flow path 30 and further, this rubber material is supplied to the roller die Dr. In this case, the ribbonlike rubber material is of such a gauge as exceeding the gap of the roller die Dr. The rubber material is stretched to the specified sectional shape using the roller die Dr, and then is stuck to the surface of the toroid-like part 1a which rotates the ribbonlike rubber material with a comparatively thin wall.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for molding a tire member having a predetermined shape by densely pasting up a ribbon-like strip on a rotary body in a state that the involution of air is reduced, and a molding method using it.
SOLUTION: This molding apparatus 1 of the tire member is equipped with the rotary body 2, a supply means 3 of the ribbon-like strip 5, a pair of rolls 4a and 4b and a position control means. The position control means is constituted so as to calculate the data of pasting angles θa-θh representative with respect to the outer surface of the rotary body 2 of respective wound strips 5a-5h, to calculate a linear equation from the relation between the winding number of times and the representative pasting angles θa-θh of the wound strips 5a-5h within a range of the predetermined winding number of times using those data and to continuously control the relative positional relation of the rotary body 2 and the roll 4a so that an average pasting angle θave. satisfying the calculated linear equation coincides with the extending angle of the roll 4a to the outer surface of the rotary body 2.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and the like for molding a tire component for suppressing occurrence of inconvenience such as breaking of a strip, discharge of excess rubber and the like in a non-stationary state wherein a rolling speed of a rotator, a strip supply speed of a strip supply means and a rolling speed of a roll are difficult to be stabilized.
SOLUTION: The apparatus comprises a rotator 2, a strip supply means 3, a pair of rolls 4a, 4b and a speed controlling means 5. The speed control means 5 calculates changes of respective speeds V1-V3 with time when the strip 6 is appropriately stuck in a time of sticking the strip wherein the rolling speed V1 of the rotator 2, a strip supply speed V2 of the strip supply means 3 and the rolling speed V3 of the rolls 4a, 4b are in a non-stationary state. While the strip 6 is stuck under the non-stationary state, the rolling speed V1 of the rotator 2, the strip supply speed V2 of the strip supply means 3 and the rolling speed V3 of the rolls 4a, 4b are controlled based on the calculated results.

Abstract: PROBLEM TO BE SOLVED: To easily mold a bead filler almost uniform in wall thickness in its peripheral direction and stable in shape. SOLUTION: The linear rubber element 34 ejected from an injection molding machine 30 is laminated on a molding disc 14 rotated around its axis while spirally bonded to the disc 14 so as to form a plurality of layers to mold a bead filler 35 and, therefore, a thickned bonded part is not present on the periphery of the bead filler 35 at any place and, even if there is a slight change in the thickness or the like of the linear rubber element 34, the change is dispersed in the peripheral direction of the bead filler to be averaged by winding the rubber element many times.
