Abstract

"PROCESSO PARA MEDIR A TENSãO EM UMA TIRA DE METAL". A presente invenção refere-se a um processo para medir a tensão em uma tira de metal (10) que corre entre dois rolos (12, 14; 26, 28) espaçados entre si, a freq³ência de vibração da tira entre as linhas de contato (16, 18) na superfície dos rolos é medida e usada como uma medição da tensão na tira.
