    摘要: A liquid jet, which is not decomposed to droplets, is guided onto a hot yarn wad in a cooling section with rod guide means, and this leads to rapid, very uniform cooling. Smooth thread travel is produced during take-off at thread speeds of 2000 m/min and more. One deflection of the thread is usually sufficient for drying purposes since the liquid is thereby centrifuged off.

    摘要: This invention relates to an apparatus for false twisting synthetic filament yarns, which apparatus is in the form of an air rotated nozzle having tangential inlet bores and two central outlet bores. The twisting chamber is set at an angle of 2.degree. to 40.degree. to the draw-off direction of the filament. The special advantage of this apparatus according to the invention is that it ensures smooth movement of the filament outside the twisting chamber.

    摘要: In order to conduct thoroughly pre-mixed hot gas into a ring spinning nozzle by a rotational flow in such a manner that sufficient quantities of hot gas are available for drying the filaments situated on the inside without causing backflow and without any significant movement of the filaments by turbulence, an annular chamber with tangential inlet is placed around the ring spinning nozzle. The internal wall of the chamber is separated from a circular chamber by equalizers in its upper region while on its underside it is separated from the spinning chamber by equalizers and metal gauzes at the level of the lower edge of the spinning nozzle. The circular chamber is also separated on its underside from the spinning chamber by equalizers and metal gauzes.

    摘要: A process for finely dividing melts according to the nozzle drawing process is described wherein the pressure gradient of the gas flowing into the inlet opening of the drawing nozzle is increased by the provision of obstacles to that flow of gas. The obstacles may be streams or jets of gas directed a traverse of the flow of gas.

    摘要: In a process for the production of mineral wool fibers according to the jet blast process, comprising issuing at least one melt stream from at least one opening in the base of a melting crucible into a converging-diverging drawing nozzle, flowing a gaseous blasting medium into the nozzle substantially parallel to the melt stream so as to separate the melt stream into fibers, the blasting medium being drawn into the nozzle by suction due to a drop in pressure produced between the nozzle inlet and outlet, and passing the fibers and sent blasting gas into a diffuser connected downstream of the nozzle to reduce the gas rate of flow, the improvements which comprise effecting(a) a maximum drop pressure in the inlet of the drawing nozzle;(b) a minimum drop pressure in the diverging portion of the drawing nozzle over a maximum length without separation (transition) of the laminar boundary layer;(c) the subsequent pressure conversion initially with a shock at a constant cross-section of the drawing nozzle and subsequently in a subsonic diffuser.
