Spinning Device  \n2.Claims  \n1.A method of spinning yarn by means of a pressurized fluid  \ncha:acterized by the fact that when the fibers are forn:ed byextruding a fiber-forming liquid throuyh a spinneret into apressure chaiber and ejecting it along with tie pressurized fluidthrough a nozzle located at the end of the chamber opposite tothe spinneret,the spinning is carried out through a cylindricaltubular nozzle which is movable within the pressure chamber andis provided on its upper end with a funnel-snaped yarn receiverhaviny an aperture angle within a range of 90°to 180.  \n2.A device for spinning yarn by means of a pressurizedfluid,the device comprising:a pressure chamber which can beriidly ana hermetically attached to a spinneret for creating apressurized atmosphere at the orifices of the spinneret,openingsfor guiding a pressurized fluid into the pressure chamber,and acylindrical tubular nozzle for ejecting the fiber-formingsubstance along with the pressurized fluid,  said nozzle beingprovided at its top end with a funnel-shaped yarn receiverhaving an aperture angle within a range of 90°to 18°,saianozzle being removably attached to the pressure chamber andmovable ina verticaldirection so that its vertical positionwith reyara to the spinneret can be adjusted.  \n3.Detailed Description of Invention  \nThe present invention relates to a method of spinaing yarnby means of a pressurized fluid and to a spinning device.   Moreparticularly,the present invention relates to a method ofspinning yarn and to a spinning aevice according to which afiber-forming substance along with the pressurized fluid areejected at high speed through a nozzle under conditions whichallow easy control and stabilization of the process.  \nThe authors of the present invention have developed a aethodof spinning which was disclosed in Japanese Patent Publication(Kohoku)No.47-31362 and according to which a spinneret ismaintained in an elevated pressure atmosphere and the fiber-forming substance is ejected along with the fluid at high speedthrough a nozzle located at the side of the device opposite tothe spinneret.    Compared to spinning processes known before,  \ne.g.,the drawing of yarn between rotating rollers,the methoddescribed in the invention mentioned above is advantageous inthat it is more simple and speedy since it allows the obtainingof fibers by mere drawing without the use of subsequenttechnological steps.  Moreover,comparea to a spinning methoausiny a suction force through a so-called \"ejector\",this methodaoes not depend on external factors and is characterizea byincreased speed.  \nNevertheless,the previous invention required that thespinneret be maintained under an increased pressure and dictatealarger overall dimensions of the device as compared to theejector method.  Especially when the type of proauct had to bechanged,the process required either the use of a number ofpressure chambers or frequent disassembling and reassembling ofthe device.  \nDigitized by the Internet A","cbCaijGGUtThpPnH","https://ap.wps.com/l/cbCaijGGUtThpPnH","pdf",943012,22,"English","# 1.
