Apparatus for making composite filament or fiber thermoplastic products
Abstract
Abstract PAPER IS ORDINARILY PRODUCED BY A FOURDRINIER PROCESS AND APPARATUS, AND TEXTILE FABRICS ARE PRODUCED BY SPINNING AND WEAVING. THIS INVENTION HAS MANY HAS MANY OF THE ADVANTAGES OF EACH AND UTILIZES A PLURALITY OF MULTI-PRODUCT SPINNER NOZZLES. A PLATE ON WHICH THE SPINNER NOZZLES ARE MOUNTED IS RECIPROCATED SO THAT FILAMENTS DISCHARGED FROM THE PLURALITY OF SPINNER NOZZLES ARE OVERLAID AND PRODUCE A THERMOPLASTIC FABRIC. THE FILAMENTS ARE COMPOSED OF MORE THAN ONE MATERIAL AND ARE CALLED COMPOSITE FILAMENTS. A MODIFICATION PROVIDES A BOX CONTAINING A PLURALITY OF CUT FIBERS WHICH ARE ADVANCED BY A CARDING LOOM PICKER. ONE OF THE SUBSTANCES DESCRIBED IN THE FIRST ALTERNATIVE AS DICHARGED FROM THE SPINNER NOZZLES IS IN THIS ALTERNATIVE SPRAYED ONTO A MOVING SHEET WHICH THEN PROCEEDS THROUGH CALENDERING AND DESIRED EMBOSSING, PERFORATING AND PRINTING ROLLS.
