The invention also relates to a method for producing this j? Thread material ", by spinning the costume in the form of continuous ribbons, before, after stretching the cargo, in the longitudinal direction of the linden trees, at least in some ribbons, the fastening is attached according to slits at intervals; the width of the ribbons does not have to exceed the diameter of a composite pool but the bands obviously cannot be completely eliminated because of the difficulties of doubling the cross-sectional shape of the nozzle for the strangeeire: te li.v .. ers ^ on-aene costume; In the case of a young woman, this would lead to the fact that the threads are directly fused with one another lengthwise,

The process of slitting is best done when the Peaks are inclined in relation to their direction of movement, d. i.e., when the pad continues the head. The inclined tips are evident from a first touch with a fiber easier to a touch old one on her distract the adjacent ligament "
