1) Convenient for setting speed
2) Precise in yarn feeding
3) Accurate tension
4) Data of production can be record
EBA positive let-off mechanism apply extensively FAG mechanical let-off mechanismon the basis of traditional Tricot warp-knitting machine and Raschel warp-knittingmachine. This mechanism run-in warp accurately and its performance is reliable. However because of inconvenient operating, slow speed and heavy noise results in meeting client's demand less and less. So Runyuan company specialize in developing EBA positive let-off mechanism which is controlled by servomotor and liquid crystal spinningthen inputs speed and warp run-in conveniently. Namely, this system not only hassuperiority of accurate and reliable mechanical run-in but also combines convenientand fast features of modern electronic technology, it really has reached highprecision and low noise. Main features of EBA positive let-off mechanism:Warp beam can be moved forwards or backwards manually at the set-up speed using a keyboard on the EBA system. It's convenient when changing new warp beam. Directly input and display yarn run-in values which controls 4 warp beams at thesame time. Using integrated electronic controlled system, so yarn run-in valuesreach 1mm per rack. Inputting values use millimeter per rack for the unit.Yarn tensile force is very precise during machine operation, which integrated applyyarn. In case of insured current yarn run-in values, convenient reappear by inputtingsame values.EBA can insure current speed of run-in warp and control run-in warp, which on thebasis of inputting warp beam data (internal perimeter, external perimeter and laps)on EBA controlled keyboard.Produced data can be recorded. EBA system records data of every warp beam and adds data of 4 warp beams. Following recorded data: produced loom-state fabric length, accumulative stopped time, machine run-in time, machine efficiency. Displaying produced loom-state fabric length via keyboard, which uses meter or yard for the unit. EBA system has automaticrecords of produced meters which come from certain period of time and obtain anyproduced meters of arbitrary machine. Limitation of inputting dataEBA system knows remainder time of operating plate wheel at any time (even have noinputted revolutions of warp beam. According to changes of warp beam, we can drawup a better producing plan. Warp beam can be moved backwards or can be stopped for a short period of time inorder to obtain certain fabric properties. EBA system can be designed high-performance warp run-in, low-performance warp run-in, normal warp run-in, warprun-in forward and backward.
