    摘要: Disclosed is a dual tire component servicer and a method for supplying a first tire component and a second tire component to a tire building drum, wherein the dual tire component servicer includes a first conveyor and a second conveyor for conveying the first tire component and the second tire component, respectively, in a supply direction towards the tire building drum. The dual tire component servicer further includes a first pick-and-place unit and a second pick-and-place unit for transferring the first tire component and the second tire component, respectively, from their respective conveyors to the tire building drum. The first pick-and-place unit and the second pick-and-place unit are automatically and independently movable relative to each other in a lateral direction perpendicular to the supply direction.

    摘要: A method for building green tyres includes: feeding an elementary semifinished product with a feeding apparatus; associating an anthropomorphic robotized arm with a forming drum; sending movement commands to the arm to move the forming drum in a working zone, the forming drum being moved while the feeding apparatus is feeding an elementary semifinished product, so that it is laid on the forming drum. Movement commands are sent to the arm, including: determining target coordinates for the arm in order to move the forming drum in the working zone; modifying the target coordinates by a correction function associated with the arm and the working zone, and using the modified coordinates for such movement commands.

    摘要: In a pneumatic tire, a partial tie rubber layer is disposed between a carcass layer and an innerliner layer in a limited manner across an entire region excluding end portions near a pair of bead portions; end surfaces on both sides in a tire lateral direction of the partial tie rubber layer are inclined surfaces that form an acute angle with respect to a surface of the partial tie rubber layer on the carcass layer side; and an inclination angle of the inclined surfaces with respect to the surface of the partial tie rubber layer on the carcass layer side is from 20° to 60°.

    摘要: An automatic splicing apparatus is provided herein for splicing together two ends of a sheet of tire material on a tire building drum. The apparatus comprises a splicer foot including a splicer foot frame, a first continuous unitary V-shaped axle, and two non-powered lower rollers. The splicer foot frame has an opening defined therein having opposing sides. The first continuous unitary V-shape axle has two arms attached to the opposing sides of the opening. The two non-powered lower rollers are mounted on the two arms of the first continuous unitary V-shaped axle so that the two non-powered lower rollers are arranged in a V-shape pattern. The apparatus further comprises a plurality of powered upper rollers configured to operate in coordination with the lower rollers to engage the two ends of the sheet of tire material.

    摘要: A manufacturing device for an unvulcanized band-shaped rubber member is provided. A position sensor detects, across a width direction of the band-shaped rubber member, leading and trailing ends of the band-shaped rubber member placed in a flat state on a conveyor, holding portions arranged side by side in the width direction hold at least one of the leading or trailing ends, with movement portions allowing the holding portions to move individually in a front-rear direction, the leading and the trailing ends are held by the leading and trailing end holding mechanisms, respectively, and a control unit controls a displacement of the movement portions in the front-rear direction based on data from the position sensor and a target length to adjust elongation in the front-rear direction at or near a held portion held by each of the holding portions to achieve the target length of the band-shaped rubber member.
