composed of stable bolts between the stable bolts there are disposed elements adapted to be shifted in the direction of the axis of rotation of the drum the shiftable elements adjust the position of yarn windings wound on on the cage drum application_number US 21242980 A description turning first to the embodiment of fig1 and 3 the main part of the arrangement according to this embodiment of the invention is a cage drum consisting of bodies 1 and 2 see fig2 in which bodies rods or bolts 3 are firmly inserted bolts 3 forming the circumference of the rotary cage drum for winding on and depositing windings 4 of yarn 5 and at the same time also determine an imaginary enveloping diameter 9 fig3 of the drum axially shiftable elements 6 determining by their external surfaces 7 fig3 an imaginary enveloping diameter 34 which is larger than the imaginary enveloping diameter 9 are situated between these stable bolts 3 parallel with the rotation axis 15 fig2 the axially outer edges 8 of the axially shiftable elements 6 simultaneously adjusting the windings 4 of yarn 5 on the circumference of the rotary cage drum formed by the stable bolts 3 the movement of the axially shiftable elements 6 is accomplished by a control disk 10 which engages by its edge 11 into a recess 12 of axially shiftable elements 6 and which is supported rotatably on a stable flange 13 so that its geometrical axis 14 is askew with respect to the rotation axis 15 of this control disk 10 and thus also with the rotation axis of the rotary cage drum which consists of bodies 1 and 2 fixed on the shaft 16 by a feather key 17 and a screw 18.
