THE PROCESS FOR PRODUCING A SLUB YARN PLIED WITH A CARRIER YARN WHICH COMPRISES CONTINUOUSLY FEEDING A MULTIFILAMENT YARN TO A SUPPLY JET AND FOWARDING THE YARN IN A HIGH VELOCITY STREAM OF COMPRESSIBLE FLUID INTO A SCREEN SURFACE; DIRECTING A SECOND HIGH VELOCITY STREAM OF COMPRESSIBLE FLUID FROM A SLUB JET AGAINST THE SCREEN SURFACE TO PROVIDE A TURBULENT ZONE BETWEEN THE TWO STREAMS ADJACENT TO THE SCREEN; INTERLACING SLUBS IN THE YARN BY CONTINOUSLY WITHDRAWING THE YARN FROM THE SCREEN SURFACE THROUGH THE TURBULENT ZONE AND THROUGH THE SLUB JET IN A DIRECTION COUNTER-CURRENT TO THE STREAM; CONTINUOUSLY FEEDING A CARRIER YARN TO THE SLUB JET AND COMBINING THE TWO YARNS; THE FALSE TWISTING THE COMBINED YARNS WITH A HIGH VELOCITY SINGLE VOTEX STREAM OF COMPRESSIBLE FLUID, BY PASSING THE YARNS THROUGH A TORQUE JET, AND INTERLACING THE YARN PLIES WITH A HIGH VELOCITY, PLURAL VORTEX STREAM OF COMPRESSIBLE FLUID, BY PASSING THE COMBINED YARNS THROUGH AN INTERLACING JET, TO FORM A PLIED YARN OF SLUB YARN AND CARRIER YARN.

YARN TREATING APPARATUS COMPRISING MEANS FOR SUPPLYING YARN AT A CONTROLLED RATE, A FEED JET FOR FORWARDING THE YARN IN A HIGH VELOCITY STREAM OF COMPRESSIBLE FLUID, SCREEN MEANS POSITIONED ACROSS THE PATH OF THE HIGH VELOCITY STREAM SO THAT THE YARN IS DEPOSITED ON THE SCREEN AND THE FLUID PASSES THROUGH THE SCREEN, A SLUB JET FOR FORMING SLUBS IN THE YARN POSITIONED TO DIRECT A HIGH VELOCITY STREAM OF COMPRESSIBLE FLUID AGAINST THE SCREEN ADJACENT TO THE STREAM FROM SAID FEED JET TO PROVIDE A TURBULENT ZONE, MEANS FOR WITHDRAWING THE YARN FROM THE SCREEN THROUGH SAID SLUB JET IN A DIRECTION COUNTER-CURRENT TO THE HIGH VELOCITY STREAM, MEANS FOR FEEDING A CARRIER YARN TO SAID SLUB JET TO BE COMBINED WITH THE YARN FROM THE SCREEN, AN INTERLACING JET FROM INTERLACING THE COMBINED YARNS TO FORM A UNITARY PLIED YARN, AND A TORQUE JET FOR FALSE TWISTING THE COMBINED YARNS.
