Patent GB-665718-A (GB)
Title: Improvements in and relating to the manufacture of artificial threads, filaments, fibres and the like
IPC: D01D5/06
Filed: 1949-09-08
Abstract: In the manufacture of artificial threads by extruding a thread-forming solution at a constant predetermined rate into a coagulating bath, the resultant thread is initially withdrawn from the bath and forwarded to and over a thread-advancing thread-storage device at a speed less than the predetermined take-up speed and the take-up speed of the thread is subsequently increased to the predetermined take-up speed.  When the machine is completely threaded up and running normally, the spinning speed and the degree of stretch imposed on the thread after it leaves the take-up device determine the speed at which the thread is withdrawn from the bath, and this speed is defined as the "predetermined take-up speed."  The thread may be passed from the take-up device to a box or bobbin where it is collected, or, in the continuous process, processed on further thread-advancing reels.  As shown, the spinning solution, e.g. viscose, is extruded through a jet 10 into a coagulating bath 11 forming a thread 12.  The thread is withdrawn by a take-up device 13 over which it is advanced in helical turns and is then led downwards through a transfer shoot 24 to a second reel 18, its path <PICT:0665718/IV (a)/1> through the shoot being set by guides 16, 17. From reel 18 it is led over reels 19, 20, 21 upon which it is processed.  In order to simplify the handling of the thread during setting-up the speed of rotation and the pitch of take-up device 13 are reduced by the mechanism 14.  The construction of the take-up device 13 and the mechanism 14 for altering its speed of rotation and pitch are the subject of Specification 665,732, [Group IX]. Specification 413,414, [Group IX], also is referred to.
