Paper mills manufacturing high-gloss paper require a specific level of gloss and smoothness after surface treatment in the super calender. Today, superior grades in gloss, surface roughness and smoothness can be achieved using the VIB GlossTech and its unique steam application technology. The VIB GlossTech is a minimum size type of steamshower for super calenders and off-line multinip calenders. Our advanced technology enables VIB Systems to provide a reliable, high-performance steam actuator with zone spacing down to 75 mm. This, coupled with our reliable and durable pneumatic actuators, provides superior benefits for today's papermakers.

VIB GlossTech Description
The most important characteristics of a calender steamshower are its capability and its ability to raise sheet gloss level without delamination and sticking on the calender rolls. These characteristics improve the sheet's cross-directional gloss profile and optimize the level, two-sideness and runability. Using the VIB GlossTech in the calender, makes it possible to control gloss profile and gloss target simultaneously.
The compromise between quality increases and profiling capability has been eliminated by increasing the velocity of the steam jets onto the web.
The VIB GlossTech has a cross-directional header to make the profiler absolutely drip free. The steam header collects all condensate which might arise from the steam supply and assures that only dry steam reaches the profiling valves.

 Finest zone arrangements and exact steam control are essential for profile correction and a consistent gloss- easy for the compact VIB profiler.
The profiling zone is fully compartmentalized, supplying high-velocity steam to each cross-direction compartment via a separate, uniquely designed actuation valve that allows optimum zone definition and precise control. The spring-loaded profile valves assure immediate steam shut-off at sheetbreak. These proprietary control valves assure finest control of steam amount to prevent delamination on coated grades. The patented VIB integrated control technology assures sophisticated calender control with limits for different grades. The VIB GlossTech heating system assures that the steam shower is always hot and immediately ready for steam application.
Primary material for VIB GlossTech is 1.4571 (316 Ti) stainless steel. Special materials in the diffuser plate assure complete heating even during longer sheetbreaks.
