摘要

PATENT ADVANCED FIBER TECHNICAL TRAINING SPIN STRETCHING AND GAS Submitter: Isover Saint-Gobain Inventors: John A. Battigelli Marie Pierre BARTHE François BOUQUET SHORT DESCRIPTION The invention relates to fiber-forming techniques comprises centrifugation of the form of filamentary material (41) from a centrifuge (10) and drawing the filaments (41) by means of a gas stream. According to the invention, a centrifuge (10) whose diameter is greater than 500 mm. By operating under the conditions of the invention is substantially improved product quality without having to reduce the produc-tion. Figure 1.
