Patent ID: 7946841

Claim:
A device for transportation of a film tube, comprising: at least one first film guide element; at least one second film guide element; and at least one third film guide element to guide the film tube such that the film tube can discharge heat to an environment thereof in an area between the first film guide element and at least one of the second film guide element and the third film guide element, the third film guide element (i) being adjustable relative to the first film guide element and the second film guide element such that the film tube can be deflected from a direct path between the first film guide element and the second film guide element, so that a path length traversed by the film tube between the first film guide element and the second film guide element is variable, and (ii) including at least two rollers each rotatably mounted in a holder that is rotatably mounted in a frame, each of the rollers being both transversely and longitudinally displaceable relative to the first film guide element and the second film guide element as an angle of rotation of the holder is varied within the frame, the first, the second, and the third film guide elements each having an axis of rotation that is parallel to each other of the film guide elements.
