It is simple to press the Pressfit cot onto the top roller body - adhesive material is no longer required and drying periods of several hours are a thing of the past.

The re-clothing process is completed in a few minutes using a hydraulic pulling/pressing tool. The aluminium tube sits firmly on the top roller body and prevents the cot from moving.

After pressing the cot onto the roller and applying a finishing grind, the top roller is ready for use immediately.
