Abstract

Patente de Invenção:<B>"DISPOSIçãO DE ENROLAMENTO PARA UMA TIRA DE PAPEL OU SIMILAR, UM CILINDRO PARA ESTE FIM E UM MéTODO PARA A FABRICAçãO DO MESMO"<D>. Disposição de enrolamento para uma tira (1) de papel ou similar, para a qual pelo menos um cilindro é colocado contra o rolo (2) para ser enrolado como um cilindro transportador, cilindro sobressalente ou de cilindro transportador (24) tendo uma circunferência cilíndrica externa (25), uma camada intermediária radialmente deformável (26) de material elastomérico conectada à circunferencial externa (25) do corpo do cilindro (24) e uma carcaça de operação cilíndrica (33) conectada à superfície externa da camada intermediária (26) concêntrica com o eixo do cilindro (24), de um material com vários milímetros de espessura que pode ser elasticamente deformado sob pressão de contato, de modo tal que a carcaça de operação (33) não possa ser apenas ligeiramente deformada em uma direção axial pelo peso do rolo (2) a ser enrolado com o qual está em contato, de modo tal que a carcaça de operação também tenha uma depressão na direção radial lateral à região de suporte que influencia o rolo a ser enrolado, a fabricação e adaptação às necessidades particulares se tornam mais fáceis quando a carcaça de operação (33) é composta de material elastomérico, o qual é radialmente elasticamente deformável a sua dureza é cem ou duzentas é radialmente elasticamente deformável (26), o material da camada intermediária (26) sendo em geral não-compressível e a camada intermediária (26) compreendendo cavidades ou espaços vazios sendo distribuídos sobre sua circunferência e fazendo a camada intermediária, como um tubo, compressível.
