摘要：A rotary head (11), for a Czochralski crystal drawing unit, has a reference
精确到百分位platform (16) which can turn about a vertical axis (A) and which has, in the region of this
axis, a vertical passageway (25) for a windable pulling element (13). A drive unit (23) is mounted on the platform for driving a horizontal shaft (22), on which is entrained an axially displaceable winding drum (15) with a helical winding groove (29) for the pulling element (13). A guide guides axial displacement of the drum such that the pulling element is guided along the turning axis (A). The novelty is that a helical guide element (30), which has the same pitch as the winding groove (29) and which rotates with the horizontal shaft (22), is provided on the shaft (22) at a point offt from the vertical turning axis (A) and cooperates with a guide nut (31) such that the pulling element portion, extending tangentially from the winding drum, is guided along the vertical axis (A).
