EVsf web stabilizer

eliminates sheet flutter in single felted dryer sections

Optimum air permeability, fabric caliper and structure are important on single felted sections to minimize surface speed differences that may arise. Sheet flutter as a result of speed variations will cause unnecessary stresses to be imposed on the sheet.

With EVsf Web Stabilizer it is easy to stabilize the web. EVsf blows air out from the area between the upper cylinder and the lower cylinder. The secondary air, which is evacuated, creates vacuum and the web is pressed effectively against the fabric in the entire area. The air is prevented from building up between the web and fabric, and no air bubble will be formed in the upper nip.

EVsf Web Stabilizer helps to achieve good runnability and drying efficiency. It also decreases web breaks and makes tail threading easier.
