Abstract

322,425. Bemberg, Akt.-Ges., J. P Sept. 11, 1928. [Divided on and addition to 299,038 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 21, 1928]. Apparatus for making filaments; ammoniacalcopper cellulose solutions, processes for making filaments from.-According to the parent Specification, artificial silk threads produced from ammoniacal-copper cellulose solutions by stretchspinning are subjected to a second considerable stretching outside the spinning funnel and are then hardened by treatment with acid. This method is now modified by applying the second stretching after the threads have been treated with acid, but before complete hardening has taken place under the action of the acid. Thus, the threads leaving the funnel may be drawn off by two rotating rollers, the one more remote from the funnel rotating at a higher circumferential speed than the other, and the acid treatment may be effected on the nearer roller or at a point between that roller and the funnel.
