Abstract

1,211,623. Coiling filaments for electric lamps. PATENT - TREUHAND - GES FUR ELEKTRISCHE GLUHLAMPEN m.b.H. 18 July, 1968 [21 July, 1967], No. 34178/68. Heading B3E. A machine for coiling the filaments of electric lamps and discharge tubes wherein a supply reel 2 is rigidly mounted on a rotating hollow spindle 1 through which the core wire 4 is fed and the coil wire 3 is withdrawn by centrifugal force in a loop 7 which is limited by a housing 5 surrounding the spindle is characterized in that, in order to increase the centrifugal force producing the wire tension at low speeds of rotation, a bead 9 is drawn loosely over the loop of wire and is pressed against the surface of the housing by centrifugal force. The bead has a bore having a minimum diameter in the middle and increasing towards the two ends.
