MANUFACTURE OF CONTINUOUS GLASS FILAMENT NONTWIST ROVING PRODUCT

摘要

PURPOSE:To enable high-effiecient manufacturing of a nontwist roving product at a low manufactruing cost, by a method wherein a shaft rotary winder, which winds a usual package product, is employed. CONSTITUTION:A nontwisted strand bundle, which is drawn from a continuous glass filament cake, is wound around a cylindrical package using an ordinary shaft rotary winder to form a usual continuous glass filament package product. A roving is then drawn in a manner to secure the package product, and the package pruduct is wound in a uniform twill around a shaft rotary winder, which has a shaft having the same diameter as that of the usual shaft rotary winder, to form an sproximately similar shaped cylindrical package. A desired continous glass filament nontwist roving product can thus be obtained.
