SECTIONAL TOROIDAL SUPPORT FOR TIRES PRODUCTION Russian patent published in 2005 - IPC

FIELD: tire industry.

SUBSTANCE: the invention is pertaining to the field of tire industry and may be used for making tires. The sectional toroidal support contains a set of sections precisely centered on a circumference around a geometrical basic axis and forming an exterior surface essentially reproducing an internal conformation of the treated tire. The sectional support contains a flange, on which there is at least one fastening element for engagement with a manipulating device and a counter flange operatively coupled to the flange in an axially opposite position. The sectional support contains the hutching devices for motionless retention of the sections between the flange and the counter flange. Each of the sections has a main body with essentially a U-shaped contour in its cross section, which is limited on one side by the external side forming an external surface and by the internal side facing the geometrical basic axis. The devices of hitching contain for each of the sections at least one fastening plate radially protruding from the internal side practically in a plain perpendicular to the indicated geometrical basic axis and a made with a capability of a removable hitching in an axial position between the flange and the counter flange. The invention is aimed at development of the new production method, that allows to produce separate elements of a tire and then to form them in correspondence with a specific sequence directly on the tire.

EFFECT: the invention presents a development of the new production method, that allows to produce separate elements of a tire with their formation according to a specific sequence directly on the tire.
