Abstract

"TAMBOR PARA CURTIMENTO DE COURO" Um tambor para curtimento de couro consiste em um corpo cilíndrico principal de material polimérico no qual uma pluralidade de cavidades ou bolsas são longitudinalmente distribuídas ao longo da superfície interna do corpo principal, as cavidades longitudinais sendo conectadas com outras cavidades que são providas em uma das superfícies circulares do corpo principal cilíndrico, e sendo também conectadas com um eixo oco comunicante com o exterior, de tal maneira que, durante a rotação do tambor em torno do dito eixo, tanto a contínua troca como a renovação do banho químico contido no tambor podem se processar. Uma armação metálica é externamente conectada com o corpo principal cilíndrico de uma maneira apropriada para a dilatação térmica do corpo principal. Pelo menos uma porta para a introdução e remoção de couros em e do tambor é mantida fechada com o auxílio de meios elásticos regulados de modo a assegurar uma perfeita vedação sob condições operacionais normais e que, ao mesmo tempo, funcionam como uma válvula de segurança no caso de aumentos anómalos da pressão interna do tambor."LEATHER DRUMING DRUM" A leather tanning drum consists of a main cylindrical body of polymeric material in which a plurality of cavities or bags are longitudinally distributed along the inner surface of the main body, the longitudinal cavities being connected with other cavities which are provided on one of the circular surfaces of the cylindrical main body, and are also connected with a hollow shaft communicating with the outside, in such a way that, during the rotation of the drum around said axis, both the continuous exchange and the renewal of the chemical bath contained in the drum can be processed. A metal frame is externally connected to the cylindrical main body in a manner suitable for thermal expansion of the main body. At least one door for the introduction and removal of hides in and from the drum is kept closed with the aid of elastic means regulated in order to ensure a perfect seal under normal operating conditions and, at the same time, act as a safety valve in the in case of abnormal increases in the internal pressure of the drum.
