Abstract

UN TAMBOR FORMADOR DE NEUMATICOS (10) DISPUESTO DE TAL MODO QUE LAS PRIMERAS PORCIONES AHUSADAS (14E) DE SEGMENTOS (14A, 14B) QUE CONSTITUYEN CADA UNO DE UN PAR DE TAMBORES LATERALES (14) Y LAS SEGUNDAS PORCIONES AHUSADAS (12E, 12F) DE SEGMENTOS (12A, 12B) QUE CONSTITUYEN UN TAMBOR CENTRAL (12) SE PUEDAN DESLIZAR UNAS RESPECTO A LAS OTRAS. A MEDIDA QUE LOS SEGMENTOS DEL TAMBOR CENTRAL (12) SON PRESIONADOS POR LOS SEGMENTOS DE LOS TAMBORES LATERALES (14) DESDE DENTRO EN UNA DIRECCION RADIALMENTE HACIA AFUERA, LOS SEGMENTOS DEL TAMBOR CENTRAL (12) SE MUEVEN RADIALMENTE HACIA AFUERA Y LOS TAMBORES LATERALES (14) ENTRAN EN EL LADO RADIALMENTE INTERIOR DEL TAMBOR CENTRAL (12). EN CONSECUENCIA SE PUEDE FORMAR UN NEUMATICO VERDE CON UNA ESTRUCTURA VARIABLE CON UN SOLO TAMBOR FORMADOR DE NEUMATICOS, DE MODO QUE SE PUEDE FABRICAR UN NEUMATICOS VERDE EN UNA UNIFORMIDAD SOBRESALIENTE SEGUN UN METODO DE UNA SOLA ETAPA.A TIRE FORMING DRUM (10) ARRANGED IN SUCH A WAY THAT THE FIRST SHAPED PORTIONS (14E) OF SEGMENTS (14A, 14B) THAT CONSTITUTE EACH ONE OF A PAIR OF SIDE DRUMS (14) AND THE SECOND SHAPED PORTS (12E, 12F) OF SEGMENTS (12A, 12B) THAT CONSTITUTE A CENTRAL DRUM (12) MAY SLIDE SOME WITH RESPECT TO THE OTHERS. AS THE CENTRAL DRUM SEGMENTS (12) ARE PRESSED BY THE SIDE DRUM SEGMENTS (14) FROM WITHIN A DIRECTION RADIALLY OUTSIDE, THE SEGMENTS OF THE CENTRAL DRUM (12) MOVE RADIALLY OUTWARD AND THE DRUMS ( 14) ENTER THE RADIOALLY INNER SIDE OF THE CENTRAL DRUM (12). THEREFORE, A GREEN TIRE CAN BE FORMED WITH A VARIABLE STRUCTURE WITH A SINGLE TIRE FORMING DRUM, SO A GREEN TIRES CAN BE MANUFACTURED IN AN OUTSTANDING UNIFORMITY ON A SINGLE-STAGE METHOD.
