摘要:
A tire assembly method and apparatus are disclosed which utilize at least two rotatable turrets (16, 18) that each have two drums (26, 28, 58, 60) and at least one transfer unit (156) for transferring tire components from one turret to another. The preferred embodiment of the invention features three turrets (16, 18, 20) and two transfer units (156, 170), wherein a carcass band is assembled on the drums of a first turret (16) the tread package is assembled on a third turret (20), and the complete tire carcass is assembled on a second turret (18), in between the first and third turrets. Simultaneous, continuous and sequential building and assembly of tire carcass bands and tread packages for a plurality of tires is provided by the method and apparatus of this invention.

The present invention proposes a machine for the manufacture of tires on a core 1 which is used for the manufacture of sa8d tires from the start of the assembling until the vulcanizing. The machine comprises, arranged adjacent to each other on a frame 5, a tire assembly station 2 comprising means for forming the raw tire by depositing the different compounds on the core 1 in the order and place required by the architecture of the tire, a vulcanization station 3, and a support handling station 4, as well as a crane 7 for transporting the core 1 between the different stations.
摘要:
A method and an apparatus for producing tread/reinforcement belt units for pneumatic vehicle tires in which a rotatable winding drum. a belt feeding device for a first and a second reinforcement belt layer, an overlay feeding device, a tread feeding device and a transfer device are provided. On a winding drum having double width and being axially movable, two tread/reinforcement belt units are simultaneously produced whereby in the first method steps the individual reinforcement belt layers are produced, subsequently two wound overlays are produced, and then two treads are applied one after another or simultaneously.

Tire building apparatus for building complete uncured tires includes a triad of orthogonally oriented tire building drums mounted on a turret rotatable about an axis inclined at an angle of between 35 and 36 degrees with respect to a horizontal plane. Each of the drums occupies successively two tire fabricating stations wherein the respective drums are oriented horizontally and a third station wherein the building drums successively occupying such third station are oriented vertically and from which completed tires fabricated in the apparatus can be removed vertically and at an elevation above the two fabricating stations so as to eliminate completely interference between the movements of tire building material coming to the machine and of the completed tires removed from the machine. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
摘要:
Apparatus for applying tread rubber to bases of circular cross section, which comprises a central shaft, means for mounting a plurality of bases on the central shaft, means for rotating said shaft to advance the bases through a succession of stations, means mounted adjacent one of said stations for applying rubber to a base advanced to said stations, means mounted adjacent another of said stations for applying rubber to the base having the rubber thereon applied thereto at said one of said stations, the rubber applied at the two stations taken together forming the tread and sidewall rubber portions of a tire, and means mounted on said central shaft for stitching the rubber applied to the base at said one of said stations firmly to the base. Further means for applying extruded rubber to the base by advance of a roller, individually braked for severing the rubber, and means responsive to the movement of the roller to the base for actuating base rotation and extruder feed.
