ABSTRACT:
A roll comprising a curved shaft upon which is rotatably mounted an elastic roller which has its circumference increasing progressively from its center to its ends. This results in the roll having a part which is axially straight or slightly curved. The article to be passed contacts the part and passes in a stable manner without distortion or permanent set therein, and receives a force extending the same in its cross-wise direction. This force makes it possible to stretch out any wrinkles in the article to be passed, prevents the wrinkles from forming and, if necessary, to extend the same in its cross-wise direction.
