Abstract: The invention relates to apparatus and a method for producing a coated film in which a cooled polymeric tubular extrudate is coated, reheated and inflated to yield an oriented, coated tubular film. The apparatus includes a coating head comprising a rotatable assembly including a support member [13] providing an orifice [14] through which the tubular extrudate may be fed, a plurality of spreading members [19] spaced-apart around the orifice, mounting means [15] for each of the spreading members operatively associated with the support member and displaceable relative thereto, and means [21] for biasing each of the spreading members into engagement with the tubular extrudate. Liquid coating medium is suitably deposited on the extrudate from a spray assembly, and the coating asembly is rotated around the extrudate thereby spreading and polishing the deposited medium to yield a uniformly coated film.
