  • Patent number: 4802941
    Abstract: The invention relates to a method and an apparatus for making webs, mats and the like of reed-like plastic straws (H), by which straw chains (K) of parallel, adjacent straws of unequal length are applied like scales on a support sheet (13). To achieve a fully automated manufacturing process, straws (H1) of equal length are first produced and arranged side by side, in parallel, to form a row (R). They are then attached together along their aligned ends and preferably also, along at least one longitudinal line dividing the row of straws widthwise, with adhesive tape (8) extending in the lengthwise direction of the row. Thereafter, if desired, the straw row (R) is cut into partial rows (T) along the longitudinal lines covered by tape.
