| description | The invention relates to the production of a cable rotating head (8), which is devoid of an abrasion ring, for a Czochralski-crystal drawing system which is used to drive a drawing cord (7) in an azimuthal and vertical manner and the nucleus of a crystal (6) is fixed therein. According to the invention, the cord rotating head (8) comprises a cord winding mechanism (15) which can be supported by a vertical hollow shaft (14), through which the drawing cord (7) is suspended in the crystal drawing system, and the cord rotating head (8) is rotationally mounted about the axis thereof and can be offset by a rotation motor (11), which is secured to the crystal drawing system, together with the cord winding mechanism (15) and the drawing cord (7) in a rotational movement, and said vertical hollow shaft (14) is surrounded in a coaxial manner by a double toothed gear (16) which is rotationally mounted opposite to the hollow shaft (14) and can be driven by a drawing motor (10) which is secured to the crystal drawing system. The double toothed gear (16) can be driven by a gear of the cord winding mechanism (15), such that the mechanical drive energy of the drawing motor (10), which is secured in a stationary manner to the crystal drawing system, can be transferred to the cord winding mechanism which rotates in relation to the crystal drawing system (15). |
