Textured surfaces
Our designers develop with modern technologies texture geometries. These are based on nature, graphical ideas or free designs which optically and tactile are realized according to the design and trend. Of course we also develop textures together with our customers according to their ideas and requirements.
In our Design Center we have the possibility of pressing developed textures on suitable decor papers (test pressing) to check them for their overall impression. Only developments corresponding to the market requirements or released by our customers go into production. |  | 
Smooth surfaces
Frequently special surface effects according to the design and the desired optical as well as tactile impressions are achieved, as ever, with smooth, specially treated surfaces.
Our standard finishes are:
• Satin 60
• Satin 90
• industrial polished

Welding seam
Our endless press belts are made from coil material. These segments or the coil material are welded according to a special welding procedure which enables direct texturing of the welding seam without intermediate copper layer.
Refurbishment of textured surfaces
Endless press belt surfaces which are worn, damaged or contaminated with pressing residues, can be refurbished in their „original condition“ by a special mechanical polishing method.
Reproducibility
The developed textures can be exactly reproduced even after years. Endless press belts delivered subsequently are therefore identical in all properties with the first delivery.
Materials | | Degree of gloss
Textured and smooth surfaces obtain their individual characteristic appearance from the degree of gloss grade adjusted exactly to the natural pattern or the desired effect.
Hard chrome plating
To increase the lifetimes and improve the release properties, a high-grade hard chrome plating is applied to the finished textured or smooth surface.
Hard chrome plating thickness:
Outside 40 – 60 µm hard chrome plated
Inside: 30 – 40 µm hard chrome plated,
