Pressure bonding products in the manufacture of tires

A tire production device is provided for pressure bonding products that are presented in a product profile (120) on a forming drum surface. The device includes a multidisc roller system (100) having a frame (102) relative to which a plurality of disc assemblies (104, 104) are disposed along a common axis. Each disc assembly includes an actuatable arm 106 that is linearly displaceable relative to the frame, a pair of removably attached demi-discs (110, 110) and a bearing (112) that accommodates rotation of the demi-discs (110). An actuator is associated with each disc assembly (104, 104) for bringing the disc assemblies (104, 104) into and out of contact with the product profile (120). A method is also provided for assembling tire components for the manufacture of tires.

PROCESS AND APPARATUS FOR BUILDING TYRES FOR VEHICLE WHEELS
20200368983 · 2020-11-26 ·

A process for building tyres for vehicle wheels includes: forming a tyre in process, the tyre including a belt structure and depositing a tread band in a position radially external to the belt structure by winding a continuous elongated element made of elastomeric material according to axially adjacent or partially overlapped coils. During the deposition of the tread band and on at least one of the coils already wound, a conductive liquid elastomeric compound is applied, the compound continuously extended between a radially outer surface of the tread band and a radially outer surface of the belt structure to generate electrically conductive paths and free zones.

TRANSFER AND POSING OF A SEMI-FINISHED PRODUCT DESTINED FOR USE IN TIRE PRODUCTION

The invention is directed to a posing assembly (30) that effects transfer and posing of a semifinished product (100) that is destined for inclusion in a tire. The invention is also directed to a tire production system (10) for transferring and posing a semi-finished product (100) that is destined for inclusion in a tire, which system includes the disclosed posing assembly. A method is provided for transferring and posing a semi-finished product (100) upon a rotating foaming drum (40) having a circumferential forming surface (40a) during a product posing cycle, which method includes a step of providing a tire production system as disclosed.

Method of building tire and tire building machine

The present technology provides a method of building a tire and a tire building machine. When bonding together longitudinal direction end portions of an outer circumferential side strip-shaped rubber member wrapped around a building drum to form a cylindrical shape, inner circumferential surfaces of projecting parts of the longitudinal direction end portions that project in a drum width direction relative to an inner circumferential side strip-shaped rubber member are supported by a support section, and the inner circumferential surfaces are positioned at a level of an outer circumferential surface of the inner circumferential side strip-shaped rubber member. In this state, the projecting parts are pressed in the drum width direction by a pressing section, and the longitudinal direction end portions are bonded together.
