ABSTRACT:
A device for producing pellets from film. A cradle is rotatably mounted about a longitudinal axis of rotation to a main frame. An axle arranged perpendicular to the longitudinal axis holds one or more rolls of film. A plurality of drive rollers pull the film from the rolls while the rolls are rotated on the longitudinal axis twisting the film into a strand. An oven located between the rolls and drive rollers heats the strand to permanently set the twist thereon. A pelletizer located aft of the drive rollers cuts the strand into individual pellets. In a modified version, glass roving is extended through the holder past the roll and wrapped with the film into a single strand. In an alternate embodiment, the roll of film is mounted to an axle having a longitudinal axis extending in the same direction as the axis of rotation. The film is pulled axially off the roll and twisted into a strand.
