2 LAIP SRL, PRATO (IT), IS LAUNCHING AN INNOVATIVE MACHINE ON THE MARKET. THE IS USED FOR DYEING BOTH KNITTED AND WOVEN FABRIC IN ROPES. AFTER TESTING TWO PROTOTYPES FOR 12 MONTHS IN TWO OF THE PRIMARY DYEING AND FINISHING PLANTS IN PRATO: EUROTINTORIA SPA AND NUOVE IDEE SRL, LAIP IS NOW READY TO OFFER ITS CLIENTS THIS COMPLETELY NEW CONCEPT IN DYEING MACHINES. IT IS A MACHINE THAT OPERATES AT HIGH TEMPERATURE AND PRESSURE, WITH A DRIVE SYSTEM THAT OPERATES EXCLUSIVELY WITH AIR TO PERMIT EXTREMELY REDUCED LIQUOR RATIOS: FROM 1.2, AND AN EFFECTIVE DRIVE SPEED AS HIGH AS 600 MT/MIN. WORKING WITH VERY LITTLE WATER AT HIGH SPEED MAKES IT POSSIBLE FOR THE DYER NOT ONLY TO DYE FABRICS WITH HIGH QUALITY, BUT ALSO TO ACHIEVE CONSIDERABLE SAVINGS IN THE RECIPE COST. A MACHINE FOR TWO ROPES WORKS WITH A MAXIMUM OF 500 LT OF WATER! IN ADDITION TO DYEING, THE AIR JET 200O CAN ALSO BE USED FOR OTHER WET TREATMENTS ON THE FABRICS, EITHER BEFORE OR AFTER DYEING. THE HIGH SPEED OF THE WET FABRIC, COMBINED WITH THE EXCEPTIONAL LOAD CAPACITY OF PATERIAL PER ROPE, MAKES THE AIRJET 2000 THE IDEAL MACHINE FOR ALL TYPES OF SOFTENING AND ENZYME TREATMENTS NOW IN INCREASING DEMAND BECAUSE OF THEIR FASHION ASPECTS. THE TECHNICAL DEPARTMENT OF LAIP HAS DEVOTED SPECIAL ATTENTION TO THE DESIGN OF THE SPRAY SYSTEM AND INTERNAL WASHING MECHANISM THAT PERMITS AN ESSENTIAL AND SIMPLE CLEANING OF THE MACHINE ITSELF. FINISHERS WHO HAVE BEEN CARRYING OUT ENZYME TREATMENTS IN THEIR CURRENT MACHINES HAVE SERIOUS PROBLEMS WITH CLEANING AND IT IS FOR THIS REASON THAT THE NEW LAIP MACHINE PROVIDES A SYSTEM THAT WILL SATISFY THEM IN EVERY WAY. THE MACHINE IS PRODUCED IN VERSIONS FROM 1 TO 4 CHANNELS WITH VARIABLE SIZED FABRIC BASKETS TO REACH THE MAXIMUM CAPACITY OF 800/900 KG IN THE VERSION FOR 4 ROPES. THE IS A HIGHLY INNNOVATIVE MACHINE BECAUSE OF CERTAIN FEATURES THAT DISTINGUISH IT ON THE RESTRICTED AND HIGHLY TECHNOLOGICAL MARKET OF AIR DRIVE MACHINES. TO ILLUSTRATE THE MAIN CHARACTERISTICS OF THE MACHINE, WE SUGGEST THAT THE READER VISIT THE LAIP WEBSITE ON THE INTERNET: AND CLICK ON AIRJET. ALL THE SECRETS OF THIS NEW MACHINE WILL BE MADE AVAILABLE IN AN INTERACTIVE WAY.

3 TECHNICAL REPORT THE MAIN FEATURES OF THE AIRJET 2000 ARE: 1) 100% AIR DRIVE OF FABRIC AT UP TO 600MT/MIN. THIS IS POSSIBLE THANKS TO THE RESEARCH CARRIED OUT BY THE ENGINEERING DEPARTMENT AT LAIP BOTH ON THE DISTRIBUTION OF THE AIR AND THE SIZE OF THE FAN. AIR DISTRIBUTION IS MADE CONSTANT THANKS TO AN INVERTER THAT DRIVES THE MOTOR THAT DIRECTS THE AIR TURBINE ONTO ALL THE ROPES OF THE FABRIC LOAD. A SYSTEM OF PNEUMATIC INTERCEPTION VALVES MAKES IT POSSIBLE TO CLOSE THE AIR FLOW ON THE SEPARATE ROPES IF ONE OF THE ROPES SHOULD BE STOPPED OR IN CASE OF SMALLER LOADS. 2) SPRAY SYSTEM SUPPLIED BY A SMALL CIRCULATION PUMP TO DYE THE FABRIC. THE CIRCULATION PUMP IN THIS CASE SERVES SOLELY TO FORCE THE DYEBATH THROUGH A SPECIALLY DESIGNED SYSTEM OF SPRAY NOZZLES. THE WATER DOES NOT MOVE THE FABRIC AT ALL BUT IS MERELY USED TO DYE THE FABRIC THROUGH A SPECIAL SYSTEM OF SPRAY HEADS LOCATED ON THE OUTLET OF THE THRUST NOZLE. THANKS TO THIS SYSTEM THE LIQUOR RATIO IS REDUCED TO A MINIMUM. 4) ROTATION REEL FREE AND NOT MOTOR- OPERATED, TO HAVE PERFECT SYNCHRONISM BETWEEN THE THRUST SPEED AND THE FABRIC SPEED. THE FABRIC ROTATION REEL IS NOT MOTOR DRIVEN AND HAS A SMOOTH SURFACE SO AS TO COMPLETELY ELIMINATE THE PROBLEM OF ABRASION OR WEAR OF THE FABRICS. IN THIS CASE, THE CRANK ONLY SERVES TO PRESENT THE FABRIC AT THE ENTRANCE TO THE NOZZLE, BUT DOES NOT DRAW IT OUT OF THE BASKET. THE FABRIC SPEED IS PROGRAMMABLE VIA INVERTER DEPENDING ON THE AIR FLOW, AND WILL THEREFORE ALWAYS BE SYNCHRONIZED AUTOMATICALLY WITH THE MOVEMENT OF THE REEL, THIS MEANS THAT THERE IS LESS NEED OF SUPERVISION BY THE PERSONNEL TO PERFORM ADJUSTMENTS OF THE REEL AND PUMPS. ON COMPETITORS MACHINES OPERATING WITH INJECTED AIR, THE CRANK IS MOTOR DRIVEN AND SERVES TO DRAW THE FABRIC OUT OF THE BASE OF THE CHAMBER TO PRESENT IT TO THE NOZZLE. IT IS OBVIOUS, HOWEVER, THAT IN THIS CASE THE DANGER OF PRODUCING SHINY PATCHES ON THE FABRIC IS GREATER. 3) RECTANGULAR DESIGN OF THE THRUST NOZZLE WITH ELIPTICAL EXTENSION FOR COMPLETE OPENING OF THE FABRIC. WITH THE FAN, THE NOZZLE IS THE TECHNOLOGICAL HEART OF THE MACHINE. ITS RECTANGULAR DESIGN ENTERS THE FABRIC IN A CYLINDRICAL STRUCTURE TO ENSURE BOTH A MINIMUM LOAD LOSS OF THE AERODYNAMIC SYSTEM AND A POSITIVE EFFECT ON THE FABRIC BY OPENING IT AND ELIMINATING THE PROBLEM OF CREASES OR CROW S FEET.

4 TECHNICAL REPORT 5) MINIMUM DISTANCE (80 CM) BETWEEN IDLE REEL AND INJECTOR. THE REEL ON WHICH THE FABRIC GLIDES IS INSTALLED INSIDE THE MAIN BODY, THUS GREATLY REDUCING THE DISTANCE BETWEEN THE INJECTOR AND THE POINT WHERE THE FABRIC FOLDS INSIDE THE HOLDING CHAMBER BEFORE RISING TOWARD THE NOZZLE ON COMPETITORS MACHINES, THE CRANK IS LOCATED IN A SPECIAL TURRET OUTSIDE THE MAIN BODY, WHICH PRODUCES A GREATER GAP BETWEEN THE BOTTOM OF THE HOLDING CHAMBER AND THE DRIVE REEL. 6) AUTOMATIC FABRIC PLAITER INSIDE THE HOLDING CHAMBER. A SPECIAL SYSTEM FOR PLAITING THE FABRIC ENSURES UNIFORM LOADING INSIDE THE BASKET. THIS FACILITATES THE PASSAGE OF THE FABRIC REDUCING THE POSSIBILITY OF MACHINE STOPPAGE DUE TO KNOTS. 7) AUTOMATIC FABRIC REWIND MECHANISM IN CASE OF STOPS THIS INSTRUMENT IS DRIVEN BY A PNEUMATIC PISTON AND FACILITATES RELEASE OF THE FABRIC INSIDE THE HOLDING CHAMBER IN CASE OF KNOT FORMATION. THE REWINDER IS PROGRAMMABLE VIA SOFWARE AND ATTEMPTS TO FREE THE FABRIC BY APPLYING LEVERAGE TO IT. THIS INSTRUMENT THEREFORE ENABLES THE OPERATOR TO WORK WITHOUT OPENING THE MACHINE TO FREE THE FABRIC. THIS IS PARTICULARLY USEFUL WHEN THE MACHINE IS PRESSURIZED. 8) INDUSTRIAL PC ON THIS NEW MACHINE LAIP HAS DEVELOPED SPECIAL SOFTWARE FOR CONTROL OF SPEED AND AIR FLOW. AN INDUSTRIAL PC THAT FUNCTIONS WITH THE WINDOW ENVIRONMENT CAN ALSO BE USED TO MAKE CUSTOMER CARE MODIFICATIONS VIA MODEM.

5 After testing these two prototypes for 12 months, laip has ascertained that this type of machine is particularly suitable for processing all those natural and synthetic fabrics that are difficult to work with in traditional machines. Here after we have listed some technical data relative to the most indicatives tests of processing carried out on the air jet Laip will present this new machine officially at the next textile machinery trade fair that will be held in Bologna from may 26 to 30, However, for those who are interested, laip is willing to demonstrate the machine in operation in prato. Laip is also agreeable to run tests of dyeing and wet finishing processes for possible clients.
