Abstract
718,371. Electro-magnetic yarn tensioning devices. CELANESE CORPORATION OF AMERICA. June 1, 1951 [June 3, 1950], No. 13079/51. Classes 120(2) and 142 (1) A yarn tensioning device comprises a wheel or pulley adapted to be engaged and driven by a yarn that is drawn past it, an electromagnet and an electric conductor that are rotatable relatively to one another by the connection of one of them to said wheel or pulley, said conductor extending into the field of said electromagnet so as to apply to said wheel or pulley a braking force whereby tension is imparted to said yarn, and means for adjusting the energizing current of said electromagnet so as to adjust said braking force. As shown, the yarn tension device 13 includes a magnet 18 comprising a coil 19 and pole pieces 21 fastened to a supporting plate 14 by screws 22. The ends of the pole pieces are bent to form an air-gap 23 in which a strong magnetic field is produced when an electric current flows through the coil 19. A sleeve bearing 24 extends up the centre of coil 19 and has mounted therein a wheel assembly 25 comprising a shaft 26 carrying a wheel 27 and a soft iron disc 28. The shaft 26 is supported on a screw 29 threaded through plate 14, the screw 29 providing means for adjusting the position of the disc 28 in the magnetic field of the magnet. A locknut 32 locks screw 29 in any adjusted position. Yarn 11 is directed to the wheel 27 by trumpet guide 36 and after passing around the wheel leaves it and passes through a guide 39. The yarn 11 causes the wheel assembly 25 to rotate, thereby moving the disc 28 in the magnetic field in the air-gap 23 thus generating electric currents in said disc which tend to oppose the rotation of the disc and exert a braking force on the wheel assembly to tension the yarn. The magnitude of the braking force may be controlled by varying the current in coil 19 or by varying the air-gap 23. Any number of such tensioning devices may be employed in,. for example, a beaming operation, in which case they can be connected in a common electric circuit and adjusted to exert the same tensioning force on each yarn. Arrangements are also described for textile apparatus incorporating tensioning devices as above, in which the braking force applied in each device is automatically varied as the apparatus is stopped, and for automatically changing the amount of this variation in accordance with the changes in the inertia of moving parts in the apparatus. Specification 669,964 is referred to.
