Abstract

TAMBOR PARA CONSTRUÇÃO DE CARCAÇA DE PNEU E SEU MÉTODO DE OPERAÇÃO. É descrito um tambor para construção de carcaça de pneu (1), tendo um eixo longitudinal (3) e dois meio-tambores (6), móveis ao longo do eixo longitudinal (3) em direções opostas, afastando-se e aproximando-se de um plano central (4) do tambor (1), cada um compreendendo um dispositivo de suporte de talão (16) que define um assento (17) e um dispositivo de virada (41), concebido para virar para cima uma porção lateral anelar (42) de uma lona de carcaça, em torno e no lado de fora de um respectivo aro de talão; o dispositivo de virada (43) possui uma porção de extremidade disposta, em repouso, ao longo de uma porção periférica anelar (18) do assento (17), conformada de modo a definir uma extensão do perfil curvilíneo do assento (17); meios de impulsionamento (50) são providos para exercerem direta e independentemente um impulso axial e um impulso radial no dispositivo de virada (43). A invenção também se refere a um método de operação do referido tambor.
