Abstract

"MéTODO E ARRANJO PARA COMPUTAR E REGULAR A DISTRIBUIçãO DE CARGA LINEAR EM UMA CALANDRA COM MúLTIPLOS MORDENTES", em que a malha de material (W) é passada através dos mordentes (N1...N9) em um conjunto de rolos (12), dito conjunto de rolos compreendendo um rolo superior de coroa variável (13), um rolo inferior de coroa variável (14) e rolos intermediários (15...22) encaixados entre os rolos superior e inferior (13, 14). Todos os rolos no conjunto de rolos são suportados de modo que, quando os mordentes (N1...N9) estiverem fechados, as linhas pendentes dos rolos fiquem curvadas para baixo. Na computação e regulagem de cargas lineares, as propriedades físicas que afetam a flexão de cada rolo intermediário (15...22) sob carga, tais como rigidez de flexão, massa, formato e propriedades de material são levadas em consideração. A relação das cargas lineares aplicadas nos rolos intermediários (15...22), o próprio peso dos rolos e as forças de suporte aplicadas aos rolos são regulados, de modo que o conjunto de rolos fique em um estado de equilíbrio e em um estado de deflexão predeterminado. A invenção refere-se também a uma calandra com múltiplos mordentes que realiza o método.
