Monforts introduced the latest MontexCoat magnetic roller coating option to virtual delegates from around the world at the World Congress for Textile Coating, organized by International Newsletters. “The magnetic roller system allows a wide range of coatings and finishes to be carried out, while being easy to handle for operators and much easier to clean at the end of the process,” said Jürgen Hanel, Monforts Head of Technical Textiles, at the recent 1st World Congress on Textile Coating.. “It provides textile finishers with an expanded range of options due to the fully-adjustable positioning of the magnet within the roller and with four different magnet positions possible, can be set to operate both as a direct coating system and as an indirect coater.”
With traditional dip coating systems, as well as with many standard knife coating technologies, there is always a difference in the tension between the center and the edges of the wide width fabrics being treated – and hence the amount of pressure with which the coating is applied. With the use of a magnetic roller, equal pressure is applied across the full width of the fabric, with consistent results even at wide widths of over 2.4 meters. In addition, adjusting the roller surface, rather than changing the coating formulation to match the required add-on and viscosity for each coating effect required, leads to much higher output from the line.
“A typical integrated Monforts coating line is automated from the inlet feed to the winder,” Hanel told delegates. “Adjustments can also be made simply and easily from the touchscreen and with the new hand-held remote controller which has recently been introduced for the MontexCoat unit.”
Manual adjustment, he added, is time consuming and needs the attention of an experienced operator or the reproducibility will not be accurate between coating operations. The adjustment by motors allows each coating to be stored and downloaded again for 100% reproducibility.
The motors can be fully controlled from the touchscreen and all necessary adjustments carried out remotely, making switching from one process to another extremely quick and easy.
The accuracy that is now being demanded by today’s most exacting customers is met with an optional carbon fiber roller – especially in dealing with the winding tension required in the processing of materials such as prepregs for composites and other heavyweight fabrics. Typical applications for the MontexCoat include the finishing of tents and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables. Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments can all be accommodated.
