Abstract

618,028. Twisting threads. SOC. RHODIACETA. Oct. 15, 1946, No. 30713. Convention date, Nov. 30, 1945 [Class 120(ii)] In a twisting machine in which the thread is given more than two twists per revolution of the spindle by mounting a support concentrically with a "doubletwist " spindle and rotating in the opposite direction thereto, the thread passes through the air gap 32 of an electric motor, of which the rotor 24 drives the thread support 9 and of which the stator 21 is fixed to the frame of the machine, during its journey between the lower orifice 7 of the spindle 1 and a fixed thread-guide 33. Support 9 is carried by a mandrel 8 to which rotor 24 is keyed. Spindle 1 is driven, by a belt acting on pulley 20, in the opposite direction to rotor 24. The thread is guided through the air gap by a cupshaped or bladed member 19 formed of electrically non-conducting material to avoid Foucault currents. Support 9 may constitute the feed bobbin or the receiving bobbin; in the latter case a thread guide device is provided for winding the twisted thread on support 9, actuated by the rotation either of the mandrel or the spindle.
