Abstract

PURPOSE:To move and disperse the nonuniformity of inflated tube in the crosswise direction and uniform the rolling position by providing revolving rolls which can be altered in gradient so as to press against the traveling inflated tube between the annular die and the pinch rolls in a film manufacturing apparatus. CONSTITUTION:At any point between an annular die 1 and pinch rolls 4 and 4', revolving rolls 6 and 6' are provided so as to press against a traveling inflated tube 2. Operating the revolving rolls 6 and 6' by using mechanisms such as pistons and reciprocating mechanisms so that their gradients are altered permits the tube to be readily revolved in both directions without distorting or wrinkling the tube.
