Abstract

498,962. Yarns or threads. SOC. ANON. VETRERIA ITALIANA BALZARETTI MODIGLIANI. March 25, 1938, No. 9262. Convention date, March 30, 1937. [Class 120 (iii)] In producing a yarn or thread by reducing a lap of filaments which cross at a constant acute angle, the lap is cut into strips along lines in a direction bisecting the acute angle of intersection between the filaments, the strips then being drawn and twisted to form a yarn. In preparing such a yarn of glass fibres the lap or web of glass filaments 1, Fig. 2, is cut into strips, which are drawn in the direction y, Fig. 4, and twisted while being wound on a bobbin 7, Fig. 5. The strips 3 may be sprayed with dressing liquids before or during drawing.
