Abstract

"MOLDE E MéTODO DE MOLDAR BANDA DE RODAGEM ANULAR". Um molde anular para vulcanizar uma banda de rodagem de anel anular é descrito. O molde anular possui uma pluralidade de segmentos internos expansíveis para fora e radialmente móveis para formar a superfície interna da banda de rodagem e uma pluralidade de segmentos externos contraindo para dentro e radialmente móveis para formar a superfície externa da banda de rodagem. Os segmentos radialmente externos são paralelogramos. Cada segmento externo quando em uma posição de moldagem fechada se estende através de um segmento radialmente interno completo e partes dos dois segmentos internos adjacentes. Os segmentos radialmente externos possuem bordas se estendendo lateralmente inclinadas relativas á direção axial do molde enquanto as bordas externas axialmente se estendendo de modo circunferencial são perpendiculares á direção axial do molde. As bordas se estendendo lateralmente inclinadas são inclinadas pelo menos 5<198>, de preferência cerca de 10<198> com relação à direção axial. Na modalidade preferida o molde possui 12 segmentos externos, cada segmento sendo de um comprimento de arco de cerca de 30<198>.
