ABSTRACT:
In extrusion apparatus for producing a continuous film of thermoplastic material, either as part of an extrusion coating or laminating process or to cast a continuous film, a chill roll which receives the film directly from the extruder is mounted on a wheeled carriage whereon it can be moved lengthwise into and out of operating relation with the other components of the apparatus without requiring lifting thereof or of other parts of the apparatus. The carriage may be proportioned to move directly between the apparatus in which it is to be used and the floor of the mill, or it may be mounted on a separate wheeled cart on which it is transported to and from the extrusion apparatus. Particularly in the latter case, provision is made for both vertical and lateral adjustment of the base structure on which the carriage is supported in its operating relation with the extruder.
