Abstract

<B>''APARELHO E MéTODO DE TESTE DE RESISTêNCIA DINâMICA DE UMA AMOSTRA DE NúCLEO DE PAPEL'' A presente invenção se refere a um aparelho de teste para a determinação da resistência dinâmica de amostra de núcleo de papel, o qual inclui um mandril pneumático rotativamente acionado para engatar na superfície interna de uma amostra de núcleo a fim de acionar rotativamente a amostra de núcleo, e um conjunto de correia de tensão variável que tem uma correia flexível passada sobre a amostra de núcleo e tensionada para simular a carga aplicada a um núcleo de papel em uso real. A correia é tensionada por um cilindro pneumático controlado sob controle de retorno por uma servo válvula e um controlador de computador de modo que a carga aplicada à amostra rastreia com precisão uma programação de carga desejada predeterminada versus o tempo.
