Abstract
356,457. Artificial silk. BRITISH BEMBERG, Ltd., Hazel House, Milk Street, London. Aug. 28, 1930, No. 25747. Convention date, Aug. 29, 1929. [Class 2 (ii).] In the stretchspinning of cuprammonium silk the thread is guided downwards in a rectilinear path and the jet of precipitating liquid is deviated from the path of the thread before or at the outlet of the spinning apparatus but before the collecting or guiding member. In this manner the thread arrives on or in the further devices of the spinning apparatus with the liquid adherent to its surface only. As shown in Fig. 1, a known cylindrical spinning apparatus 1 has an exit pipe 2 surrounded by tube 3. The tube 3 is connected to pipe 2 by a seal 5, and has a siphon tube 4. The quantity of liquid drawn off by the siphon may be adjusted by a tap 6. The thread issuing from the spinning cell with only superficially adhering liquid is guided directly over two rods 13 in a hardening bath 12 underneath the spinning apparatus. The thread issuing from the spinning apparatus may alternatively be passed vertically downwards to a roller round which it passes and upon which it is sprayed with acid. It is passed horizontally from the first roller to a second roller after which it is collected in a centrifuge. As shown in Fig. 3, the siphon tube is dispensed with and the tube 3 is provided with a small rod or sheet-metal member 10 which diverts the current of liquid issuing from the apparatus away from the path of the thread. As shown in Fig. 6, the tube 3 has a siphon tube 4 the lower end of which projects below the orifice of tube 3 and carries an overflow vessel 16. The vessel 16 is slidably mounted on the tube 4 by means of a resilient sleeve 17. The rate of flow of liquid through the tube 4 may be regulated by adjusting the position of the vessel 16 on the tube 4. The thread issuing from the tube 3 may be passed vertically downwards to a driven roller, then vertically upwards to another roller displaced with respect to the first, and then led to a centrifuge, reel, or bobbin. For economy of space, the spinning apparatus, guiding and withdrawal rollers, and the receiving apparatus for the thread may be arranged vertically underneath one another.
