Yarn texturizing method and apparatus

Abstract

Abstract METHOD AND APPARATUS FOR TEXTURIZING MULTI-FILAMENT THERMOSPLASTIC YARN. THE YARN IS FED INTO A YARN DELIVERY TUBE HAVING A TERMINAL END PROJECTING INTO A LARGER TUBE. THE LARGER TUBE TERMINATES AT A TEXTURIZING ZONE DEFINED BY THE BIGHT BETWEEN A PAIR OF OPPOSED MESH BELTS AS THEY PASS AROUND THEIR RESPECTIVE SUPPORT ROLLERS AND BY ADJUSTABLE PLATES CONTROLLING THE WIDTH OF THE ZONE. AIR UNDER PRESSURE AND WITH A SWIRLING MOTION IMPARTED THERETO IS FED INTO THE LARGER TUBE, THE AIR FLOWING THERETHROUGH TO THE TEXTURIZING ZONE AND DRAWING THE YARN THEREWITH AND CAUSING THE YARN TO TWIST AS IT LEAVES THE YARN DELIVERY TUBE. AS THE YARN REACHES THE TEXTURIZING ZONE THE SWIRLING CURRENT OF AIR CAUSES THE YARN TO FORM SPIRALS WHICH ARE CONFINED IN OVERLAPPING COMPACTED RELATIONSHIP AS THEY ENTER THE BIGHT BETWEEN THE BELTS. DURING THE PASSAGE OF THE YARN BETWEEN THE BELTS IT IS SUBJECTED TO HEATING AND THEREAFTER TO COOLING. AFTER THE YARN LEAVES THE BELTS IT IS TENSIONED TO BULK THE YARN AND THE TENSION IS THEREAFTER RELAXED AND THE YARN WOUND INTO A PACKAGE.
