Abstract

"DISPOSITIVO E PROCESSO DE ENROLAMENTO DE UMA EXTREMIDADE DE UMA LUVA CILìNDRICA EM TORNO DE UM ANEL TóRICO". Dispositivo (D) de enrolamento de uma luva cilindrica (C) de eixo XX<39>, em torno de um anel tórico (R) de tal maneira que a extremidade (E) da dita luva cilíndrica esteja engastada entre o anel de tórico (R) e a luva cilíndrica (C) propriamente dita para dar pelo menos uma volta completa em torno da seção radial sensivelmente circular do dito anel tórico (R), dispositivo caracterizado pelo fato de que compreende uma tela de enrolamento (T), igualmente formada por uma luva deslizante livremente na direção axial sobre a superfície externa de um conjunto concêntrico de cabeças de enrolamento (10, 10<39>) que apresentam um perfil externo que compreende um dorso (104) que constitui uma superfície sensivelmente cilíndrica do eixo XX<39>, uma superfície anular frontal convexa (102) ligada à superfície precedente, e uma superfície anular cóncava (103) ligada a esta última de maneira que a tela de enrolamento (T) forma laços em forma de S, quando a dita tela de enrolamento (T) segue sensivelmente o perfil radial da superfície anular convexa (102) e a superfície anular cóncava (103) das ditas cabeças de enrolamento (10, 10<39>).
