ABSTRACT:
A method of controlling lateral wandering of flattened tubular plastic film in gauge distribution apparatus in which gauge distribution is effected by passing a flattened tubular plastic film around at least one turning bar whose position with respect to the film is varied. The method comprises adjusting the position of a turning bar in response to a signal from the sensor which senses the position of one of the side edges of the flattened film before it is wound on a storage roll. When lateral wandering of the flattened tubular film is sensed, the position of the turning bar is varied until the sensor detects that the film has returned to its desired path.
