Abstract
"PROCESSO PARA OBTER UMA BANDA DE RODAGEM DE MISTURA DE BORRACHA". Processo para obter uma banda de rodagem (21) que comporta uma superfície de rodagem (3) limitada axialmente por faces laterais uma ranhura (61) e um canal situado radialmente sob a superfície de rodagem e desembocando sobre pelo menos uma face lateral da banda de rodagem (21) e em pelo menos uma parede lateral (15,) da ranhura (61), este processo comportando (a): moldagem da banda de rodagem (21), o canal sendo prolongado no interior da ranhura (61) de modo que pelo menos um plano (101), que é localmente tangente à parte radialmente externa ao canal da parede lateral (15) sobre a qual desemboca o canal, divide o canal em duas partes (115 e 215); e (b) ablação de pelo menos uma parte da mistura moldada em torno do canal no interior da ranhura (61), com uma ferramenta de corte que segue o perfil da ranhura (61).
