AIR JET WEAVING DEFINATION: AIRJET WEAVING INVOLVES INSERTING A PREDETERMINED LENGTH OF YARN THROUGH THE WARP SHED BY MEANS OF COMPRESSED AIR. DIFFERENT SYSTEM OF AIR JET WEAVING SINGLE NOZZLE WITH CONFUSOR TYPE GUIDE MULTIPLE NOZZLES WITH GUIDES MULTIPLE NOZZLES WITH A PROFILE REED ( WIDELY USED IN MARKET)

AIR JET WEAVING DIFFERENT MOTION OF AIR JET WEAVING MACHINE (TSUDAKAMA JAPAN ) DRIVE : DRIVE IS GIVEN BY 3.7 KW MOTOR BY MEAN OF COMBINED V BELT & ELECTROMAGNETIC CLUTCH TRANSMITS DRIVE TO MAIN SHAFT.ALL DRIVE GEARS ARE IN OIL BATH AND BECAUSE OF THIS HIGHER SPEED OF LOOM CAN BE ACHIVED.

AIR JET WEAVING DIFFERENT MOTION OF AIR JET WEAVING MACHINE (TSUDAKAMA JAPAN ) SHEDDING MOTION: THERE ARE TWO TYPES OF SHEDDING MOTION I) NEGATIVE SHEDDING II) POSITIVE SHEDDING I) NEGATIVE SHEDDING : IN NEGATIVE SHEDDING HEALD FRAMEDOWN MOVEMENT IS DONE BY SNGLE CAM AND RETURN OF HEALD FRAME IS DONE BY MEANS OF SPRINGS.THESE SPRINGS CAN BE ADDED OR REMOVED AS PER THE REQUIREMENT.NEGATIVE SHEDDING GOT LIMITATION OF LOOM SPEED & ELONGATION OF ROPE OR UNDERWIRE WHICH IS MADE UP OF SYNTHETIC MATERIAL.IN NEGATIVE SHEDDING MAXIMUM 8 HEALD FRAMES CAN BE USED.

AIR JET WEAVING DIFFERENT MOTION OF AIR JET WEAVING MACHINE (TSUDAKAMA JAPAN ) II) POSITIVE SHEDDING : IT IS A RELIABLE MEANS OF MAKING HEALD FRAME UP & DOWN BY TWO DIFFERENT CAS. IT IS A COMBINE CAM ON WHICCH FOLLOWER ROLLS OF SHEDDING LEVER AND THIS WAY UP & DOWN MOVEMENT IS DONE.

AIR JET WEAVING DIFFERENT MOTION OF AIR JET WEAVING MACHINE (TSUDAKAMA JAPAN ) MEASURING & STORAGE IT IS THE EQUIPMENT WHICH KEEPS PREDETERMINED LENGTH OF WEFT YARN ON DRUM OF WEFT ACCUMULATOR EQUAL TO 3 PICKS LENGTH .THIS KEEPS RESERVE OF 3 PICKS LENGTH ON THE DRUM.

AIR JET WEAVING DIFFERENT MOTION OF AIR JET WEAVING MACHINE (TSUDAKAMA JAPAN ) WEFT INSERATION IN AIR JET AS THE WEFT YARN IS CARRIED BY NEGATIVE MEANS,THE SHED OPENING SHOULD BE CLEAR,EVEN SMALL HANGING OF THREAD IN WARP SHEET WILL STOP PASSAGE OF WFT YARN & IT WILL NOT PERMIT WEFT TO REACH THE OTHER END OF THE SHED & STOP THE LOOM AT ONCE

AIR JET WEAVING DIFFERENT MOTION OF AIR JET WEAVING MACHINE (TSUDAKAMA JAPAN ) WEFT INSERATION IN MOST AIR JET WEAVING THERE ARE TWO MAIN NOZZELS & 5 SUB GROUPS OF RELAY NOZZLES, CONSISTING 5 SUB NOZZELS IN EACH GROUP AT THE EQUAL DISTANCE OF 80 MM PITCH UPTO 4 GROUPS.IN THE LAST GROUP RELAY NOZZLE ARE DISTRIBUTED EQUALLY AS PER WIDTH OF THE FABRIC.

AIR JET WEAVING DIFFERENT MOTION OF AIR JET WEAVING MACHINE (TSUDAKAMA JAPAN ) WEFT INSERATION COMPRESSED AIR REGULATED & CONTROLLED AT THE PRESSURE OF 3.5 TO 4 KG/CM2 ENTERS THE MAIN NOZZLE WHICH PUSHES WEFT YARN TOWARDS WARP SHED.THE SUB NOZZLE GROUP,RECEIVES REGULATED AIR FROM SUB AIR TANK WHICH PUSHES WEFT YARN ON BY ONE.THE AIR IS BLOWN AT DIFFERENT TIMINGS OF DEGREE IN INDIVIDUAL GROUPS OF SUB NOZZLES & WEFT YARN IS CARRIED THROUGH SHED. MOST VITAL PART IS LEFT HAND SIDE WEFT CUTTER AS IN ALL SHUTTELLES LOOMN IT PLAYS VERY IMPORTANT ROLE AS EVERY PICK IS INSERTED & THEN CUT.

AIR JET WEAVING DIFFERENT MOTION OF AIR JET WEAVING MACHINE (TSUDAKAMA JAPAN ) 5.LET-OFF MOTION – ELO ELECTRONIC LET-OFF MOTION.THIS MOTION IS CONTROLLED BY LOAD CELL PLACED ON WHIP ROLL & AMOUNT OF TENSION OF WARP CREATED IS IN KGF & TRANSMITTED TO SERVO MOTOR THROUGH MICROPROCESSOR & THEN IT GOVERNS THE REVOLUTION OF SERVO MOTOR IN TURNS TO WARP BEAM THROUGH WORM WHEEL , WORM GEAR & BEAM PINION. THE VALVES ARE FED TO IN THE MICROPROCESSOR ARE 1. WARP TENSION IN KGF 2.BEAM DIAMETER IN CMS

AIR JET WEAVING DIFFERENT MOTION OF AIR JET WEAVING MACHINE (TSUDAKAMA JAPAN ) 5.TAKE- UP MOTION – MTU & ETU MECHANICAL TAKE UP (MTU) IT IS A 7 WHEEL TAKE UP MOTION & AS PER REQUIRED PICKS/INCH PICKS WHEEL ARE CHANGED. ELECTRIC TAKE UP (ETU) THE RQUIRED PICKS / INCH ARE FED IN MICROPROCESSOR.

AIR JET WEAVING DIFFERENT MOTION OF AIR JET WEAVING MACHINE (TSUDAKAMA JAPAN ) 6.SELVEDGE FORMATION : IT IS THE LENO SELVEDGE.THE TWO THREADS OF 75 DENIER , 450 TPM GETS TWISTED & BINDS THE SELVEDGE OF THE FABRIC WFET DETECTOR : IN AIR JET LOOM THERE ARE TWO FILLING DETECTORS H1 & H2 FEELERS. THE PURPOSE OF H1 FEELER IS TO STOP THE LOOM IN THE CASE OF WEFT YARN DOES NOT REACH IN FRONT OF THE FEELER.WHEREAS PURPOSE OF H2 FEELER IS TO STOP THE MACHINE IF WEFT YARN REACHES IN FRONT OF THE FEELER.THESE FEELERS WORKS ON THE PRINCIPLE OF REFLECTION. THERE ARE TWO EYES ON FEELER ONE IS IMMITER AND THE OTHER IS RECEIVER.THE REFLECTION IS DONE THROUGH STAINLESS STEEL PROFILE REED WHICH IS IN FRONT OF THE TWO FEELER

AIR JET WEAVING DIFFERENT MOTION OF AIR JET WEAVING MACHINE (TSUDAKAMA JAPAN ) WARP STOP MOTION: ELECTRICAL WARP STOP MOTION WORKS ON THE PRINCIPLE OF CONTACT & CIRCUIT IS COMPLETED AS SOON AS DROP WIRE IS COMING IN CONTACT WITH SERRATED BARS AND LOOM STOP DURING BREAKAGE OF WARP YARN
