ABSTRACT:
A device for producing pellets from film. A cradle is rotatably mounted about a longitudinal axis of rotation to a main frame. All axle arranged perpendicular to tim longitudinal axis holds a roll of film within the cradle. A second roll of film is mounted outside of the cradle, is held by a second axle arranged perpendicular to the longitudinal axis of the cradle, and is fed into the cradle to a position adjacent and parallel to film unwound from the first roll. A plurality of drive rollers pull the film from the rolls while the rolls are rotated about the longitudinal axes twisting the film into a strand. An oven located between the rolls and drive rollers heats the strand to permanently set the twist therein. A pelletizer located aft of the drive rollers cuts the strand into individual pellets. In a modified version, the second roll is split into multiple sheets prior to entering the cradle by one or more film splitters.
