摘要： The invention relates to a method and a device for melt spinning and cooling synthetic filaments. A plurality of filaments is extruded from a polymer melt by means of a plurality of nozzle holes of a spinneret and is guided, after the extrusion, into a cooling shaft for the purpose of cooling, a part of the cooling air being exhausted out of an inlet end of the cooling shaft by means of an exhaust equipment opposite to the running direction of the filaments, in order to discharge the volatile components arising during the melt spinning for preventing deposits on the spinneret plate. In order to achieve the most uniform flushing effect possible below the spinneret, the size of a suction port at the inlet end of the cooling shaft is changed according to the invention for adjusting the exhaust of the cooling air, the filaments being guided together through the suction port after the extrusion.

摘要： The invention relates to an apparatus and a method for depositing synthetic fibers to form a non-woven web, in which method the synthetic fibers are guided in the form of a blowing stream through a drawing unit for being deposited on a deposit belt. For this purpose, inside the guidance distance between a blast opening of the drawing unit and the deposit belt, several guidance means are arranged, which form a guidance channel above the deposit belt, wherein the guidance means form a channel opening of the guidance channel at a distance from the blast opening of the drawing unit. In order to achieve constant strength in the deposition of the fiber strands in the non- woven web, the distance between the outlet of the drawing unit and the channel opening of the guidance channel is larger than half the guidance distance according to the invention, wherein the guidance width of an open space formed between the outlet of the drawing unit and the channel opening of the guidance channel is larger than that of the guidance channel.

摘要： The invention relates to a method and an apparatus for drawing and depositing a plurality of fibers to form a non-woven, in which method the synthetic fibers are guided by means of a drawing unit in the form of a blowing stream for being deposited on a deposit belt. When the blowing stream emerges out of the conveying channel into an open space below the drawing unit, a suction stream caused by a natural suction effect is generated, the blowing stream and the suction stream being guided jointly through a short guidance distance towards a deposit belt for depositing the fibers. In order to prevent the effect of the suction stream from influencing the guidance and deposition of the fibers, the suction stream is generated according to the invention out of the ambient air outside of an ambience influencing the deposition of the fibers. For this purpose, conducting means are provided below the drawing unit for guiding the suction stream generated out of the ambient air.

摘要： The invention relates to a process and a device for melt-spinning and cooling synthetic filaments. Therein, a plurality of filaments is extruded from a polymer melt and, after the extrusion, is guided into a cooling shaft for cooling. Within the cooling shaft cool air is blown, via a blower wall, into the cooling shaft, where, for cooling, the filaments are guided along the blower wall and at a distance from it. In order to obtain cooling adapted to the particular filament titer, the blowing onto the filaments can be set according to the invention by selecting one of several operating positions, where to change the operating position of the blower wall it is moved in the direction towards the filaments or in the direction away from the filaments.
