摘要： This invention concerns the manufacture of a layer of elastomeric material to form part of a pneumatic tire, and the manufacture of a reinforced elastomeric layer. According to the invention a layer of elastomeric material is formed as a progressive helical winding along a mandrel. The layer may be transferred in cylindrical form to a tire carcass building former to constitute an inner lining for a tire carcass, or a reinforcement filament may be wound over the layer producing a cylindrical reinforced layer which is cut to produce a ply of coated fabric.

摘要： PROCEDIMIENTO Y APARATO PARA LA FABRICACION DE NEUMATICOS CINTURADOS Y RADIALES. CONSISTE EN LA UNION DEL PAQUETE FORMADO POR EL CINTURON (10) Y LA BANDA DE RODADURA (11), FABRICADOS POR SEPARADO, CON LA CARCASA (12) QUE ESTA EN REPOSO SOBRE UN TAMBOR DE CONSTRUCCION. EL CINTURON Y LA BANDA SE SUJETAN POR MEDIO DE UNA PLACA DE APRIETE (1) UNIDA CON EL ANILLO DE TRANSFERENCIA (8). MEDIANTE EL CIERRE DEL TAMBOR SE ABOMBA LA CARCASA CUYO CENIT SE PONE EN CONTACTO CON EL PAQUETE (10, 11); AL MISMO TIEMPO SE CIÑEN A LA CARCASA (12) LOS DOS MANGUITOS DE GOMA (7) CIRCULARES QUE CIERRAN HERMETICAMENTE, Y EL AIRE CONTENIDO EN EL ESPACIO COMPRENDIDO ENTRE CARCASA (12), MANGUITOS (7) Y ANILLO (8) SE EVACUA POR LOS ORIFICIOS (16). SEGUIDAMENTE SE EXPANDEN LOS FUELLES DE RODADURA (5) QUE PRESIONAN LA BANDA Y EL CINTURON CONTRA LA CARCASA, PRODUCIENDO UNA UNION FIRME; MEDIANTE LAS OPERACIONES INVERSAS SE LIBERA EL NEUMATICO, QUE SE LLEVA A LA PRENSA CALIENTE.

摘要： The tread of a pneumatic tire is bonded to a toroidal shaped radial tire carcass and a reinforcing structure which has discontinuities in its thickness in two planes parallel to the equatorial plane of the tire by a stitching process wherein the annular central portion of the tread while unvulcanized is first rotated against a brush. The lateral portions of the tread which overlie the thickest edge portions of the reinforcing structure are also pressed by rotating brushes commencing while the central portion is being pressed and the annular areas of the tread intermediate the center and lateral areas are pressed with metallic discs. The lateral portions of the tread overlying the thickest parts of the reinforcing structure are then pressed with metallic discs. The process and apparatus having two sets of brushes to achieve the sequence of pressing steps adhere the unvulcanized tread to the underlying structure without air bubbles being trapped therebetween.

摘要： In the formation of an elastomeric tube or the like on a toroidal core, elastomeric material is applied to the core generally along one side of the core, and force-applying means are utilized to press annular portions of the so-deposited elastomeric material onto the core. Cutting means are also included for cutting away elastomeric material not deposited on the core. The core and elastomeric material deposited thereon are then turned over and the operation is repeated, whereby elastomeric tube means or the like are provided on the toroidal core.

摘要： Method and apparatus for use in building a closed torus tire. An expandable sleeve having an inflatable portion expands to wrap a sheet of tire building material partially about a disintegratable generally toroidal core. A bladder beneath the sleeve is then inflated to roll the sleeve toward the core causing the edges of the sheet to flip or snap from the sleeve surface to the core surface. The apparatus includes a drum expandable to either of two fully supported and different building diameters enabling stable support first of the core with at least one sheet of material engaged with the internal circumference of the core, and then the core with added thickness of tire components engaged with the internal diameter of the core.
