Model NO.: RFJA 20 Certification: ISO Specification: Reed width: 190cm ~ 390cm HS Code: 8446305000 Type: Weaving Machinery Trademark: RIFA Origin: Liaocheng Shandong Province, China [Weaving Range]This model air jet loom can weave various nature, manmade, synthetic fiber and blended spinning fiber.[MORE NEW FUNCTION THAN RFJA10]New style electric control systemCreatively designed new style positive let-off systemEquipped with low vibrant balanced beating systemLet-off system with double back rollerAdopts super low-power electro-magnetic valveWeaving Navigation System.[Characteristic]1. New electronic control systemWeaving Navigation System can scoutthe working situation during loom running, can guide the loom to chose the best weaving technology as per all the situation; Can automatically set the best weaving parameters as per loom condition and fabric specifications; Further improved auto-set system and weft brake system which prevent stop mark.2. New type positive let-off motionTo ensure high-speed running we designed new type positive let-off motion for JA20, the let-off motion is fitted on outside of side boards, so eccentricity can be adjusted easily.3. Low vibrant balanced beating systemBox-board on both sides and front beam are designed with high rigid structures, it is with good anti-vibration and durable even weaving heavy fabrics at high speed. General y equipment of supporter on the rocking shaft and rocking balancer can realize smooth and strong beating at high speed for perfect fabric.4. Flexibility for high speedAdopts high rigid frame structure, big diameter beam gear and positive let-off driving beam with bath lubrication, which make loom suit for the high density fabric at high speed. The flange diameter is up to 1100mm if necessary.5. Double back rollerLet-off motion adopts double back roller which keep tension constant and fit for weaving various heavy or light fabrics.6. Low-power weft insertionThe sensor of new electro-magnetic valve is higher, makes air pressure stable while jetting accurately at ultra high-speed. Valve is connected with front-beam and air groove. Which shortens the distance from valve to nozzle, improve the efficiency.
