to conveyor belt 27 in order to deposit the yarn one loop at a time upon the conveyor belt a counter roller 28 is fitted between the conveyor belt and the device for depositing the yarn the operation of the device will be described hereinafter the yarn a supplied from several yarn bobbins c is led via hollow shaft 1 and opening 9 to yarn guiding eyelet 14 from where the yarn is wound around drum 18 when motor 6 is started the hollow shaft 1 will be driven in rotation in roller bearings 7 via belt pulleys 4 2 and driving belt 3 extension 10 which is slantingly fitted upon said shaft is then driven so as to rotate together with arm 13 and yarn guiding eyelet 14 hereby the yarn guiding eyelet 14 which rotates around the drum lays the yarn a onto this drum pressure disc 21 which is fitted by means of roller bearings 19 upon the slanting extension 10 which is driven so as to rotate and which fits over the teeth 23 of drum 18 so that the latter can 39 t rotate thereby performs a wobbling motion so that the yarn is constantly pressed to the free end of cone shaped drum 18 the joint rotation of drum 18 and of pressing off disc 21 is prevented by the pins 25 which are fitted in a fixed ring 26 and cooperate with openings 24 provided in disc 21 and by the teeth 23 of drum 18 which pass through slots 22 in disc 21 in consequence.
