Perfectly Matched machining and grinding for perfect alignment of rolls, bearings and gears.
Each tension stack can be equipped with an automatic lubrication system for the gears. The number and size of tension stack rollers and bearing is determined by load requirements. Double shell cooling rolls are provided to cool the web after the oven with the cooling water moving in a spiral between the two walls. For machines with lower production requirements or for lighter fabrics the cooling rollers can be combined with tensioning rollers.
Drying & Heat Setting Chambers
A series of vertical dryers heated by direct fired modulating gas burners, supplied for use
with sulphur free Natural Gas. Can be precisely controlled to obtain drying and heat setting temperatures within required tolerance. The radial blowers circulating the air in the treatment chamber are directly coupled to inverter controlled AC motors to obtain the required air velocity. The web passage through the dryer is vertical and the turning rollers are water cooled.
For light belting and chaefer fabrics, the line is equipped with a stenter to impart weft wise stretch to the dipped fabric during the heat setting operations.
Edge Trimmer
Several slitting options offered for edge trim, including trim removal. For Chafer Fabrics, an ultrasonic Fabric sealing device can be provided prior to the fabric slitter.
Wind-up
Turret type or stationary surface windup to match individual process requirements. The precise Surface Winders produce rolls up to 2000 mm diameter and ensures a finished roll with straight edges within a close tolerance.
Drive
The machine is equipped with AC inverter drives having Vector control technology to provide the highest level of accuracy and are controlled by a PLC to maintain speed and tension.
Controls
Defect free fabric needs constant tension and must be perfectly centered and properly guided throughout its run in the machine. Load cells provide closed loop control for tension. Centering arrangements, web aligners and expanders are provided as required by the process and the fabric.
PLC with an HMI monitors and records process information. Controlling these critical and crucial functions via recipe management, SWASTIK RFL Dipping Lines assure consistent process conditions one lot after another, year after year.
The recipe manager automatically sets speed, temperature, tension, and other variables to simplify
operations.
The operator interface (HMI) is an easy-to-use, intuitive graphic colour display.
The PLC stores data for historical trending and can print a quality report on request.
Modem communication can be provided for remote diagnosis. |
