Device (1) for use in a roll frame (10) for the manufacture of a plastics film, having a continuous band (2), looped around at least two deflection rolls (3, 3'), for pressing the plastics film against a roll (9) of the roll frame (10), the two deflection rolls (3) being rotatably mounted on both sides in lateral bearing devices (5, 5') and fastening means are provided for fixing the deflection rolls (3, 3') in a bearing device (5) and the other bearing device (5') is pivotably mounted for the exchange of the continuous band (2); and a process for changing a continuous band (2) for pressing a plastics film against a roll (9) and for cooling the same, which is looped at least around two deflection rolls (3) rotatably mounted in lateral bearing devices (5, 5'), the deflection rolls (3, 3') being fixed in a bearing device (5). Fastening means of the other bearing device (5') are released and the other bearing device (5') is pivoted.
