    摘要： Apparatus comprising stretching means for stretching a strip of thermoplastic resin film at least longitudinally thereof, first guide means disposed to the rear of the stretching means and comprising a pair of rotatable members for nipping the stretched film strip on its front and rear surfaces widthwise thereof, second guide means disposed to the rear of the first guide means and located at a position deviated from the direction of straight advance of the film strip toward one side, and takeup means disposed to the rear of the second guide means. When the stretched film sent out from the first guide means passes through the second guide means, the second guide means restrains one side edge of the film strip. The opposite side edges of the stretched film strip are progressively gathered together toward the direction of advance of the film strip while the film strip advances from the first guide means to the second guide means. The restrained one side edge of the film strip is thereby rolled up helically, permitting the other side edge thereof to be helically rolled around the resulting rolled portion, whereby an untwisted string having a spiral cross section is obtained. The apparatus may further include heat-setting means and heating means. The heat-setting means is incorporated into the second guide means or disposed to the rear of the second guide means to heat-set the outer peripheral portion of the rolled string without heat-setting its interior. The heating means is provided to the front of the second guide means to heat-set only one edge of the helically rolled strip on the outer surface of the string.

    摘要： A device and method 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 therein. 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.
