WEB TENSION PROFILE MEASURING METHOD AND A ROLL FOR APPLYING THE SAME
摘要
A method and a roll for measuring a tension profile is provided. The roll has planted on its surface a spirally helical pressure-sensitive film sensor, such as an EMFi pressure-sensitive film sensor, which makes contact with a web obliquely and which, co-directionally with the web, has a measuring range which is substantially equal to or shorter than a web overlap angle when the roll is used for measuring a lateral tension profile of the web.
