Abstract

<B>"ROLO DE ESTENDIMENTO"<D>. A presente invenção se refere a um rolo de estendimento (1). Tal rolo inclui um eixo central curvo (2) e segmentos de rolo (3), dispostos em um modo rotativo ao mesmo e incluindo um casco cilíndrico (4) e pelo menos um dispositivo de suporte radial (5), orientado contra o eixo curvo. Com uma construção de acordo com a invenção, é obtido tal rolo de estendimento, em que os segmentos de rolo são dispostos de tal modo que o vazamento de água dentro do rolo de estendimento não irá afetar negativamente o funcionamento do rolo. O dispositivo de suporte radial (5) e o eixo curvo (2), são, no presente caso, montados juntos, para girarem entre si com a ajuda de um mancal corrediço (6).
