Abstract
A process for manufacturing a continuous yarn, which entails the steps of: PA1 a) continously impregnating a mat of mechanically held-together fibers with a mixture of anhydrous size in a liquid state; PA1 b) continuosly taking up at least some of the mixture of the anhydrous size by a sizing roller in contact with the mat such that a liquid film having an almost constant thickness of less than 8 .mu.m is formed thereon; and PA1 c) depositing the mixture of the anhydrous size, using the sizing roller, on a surface of at least some of a multiplicity of continuous filaments which are formed by mechanical drawing of at least a multiplicity of streams containing molten glass flowing out of orifices of at least one device.
