Abstract

alandra, e método para o tratamento de materiais de trama (w) com uma calandra. calandra para tratar materiais de trama, compreendendo uma estrutura para suportar dois rolos aquecidos formando um estreitamento, em que cada rolo tem relevos de superfície (rr) e em uma configuração operacional da calandra os relevos de um rolo são radialmente opostos aos do outro rolo, cada rolo gira com uma velocidade angular predeterminada em torno de seu eixo, os rolos são aquecidos por meios de aquecimento e cada rolo sofre um alongamento axial como consequência de seu aquecimento. a calandra compreende meios de detecção (e1, e2; is) adaptados para detectar o alongamento axial de cada rolo e uma unidade de controle programável (ucp) conectada aos meios de detecção e aos meios de aquecimento. a unidade de controle é programada para determinar a diferença entre os alongamentos axiais dos rolos e emitir um sinal de alarme se o valor absoluto dessa diferença for maior que um valor limite.
