<p>The material which is to be laminated is passed between two belts which run over two sets of rollers, Pressure is exerted on the belts on the sides which face away from the material. The pressure is generated by hydraulic fluid in chambers of the pressure plates. The chambers are surrounded by seals mounted in grooves round the chamber. The seals consist of a rim behind which a lip seal is mounted. A double li seal is mounted behind a second rim located at the outside of the pressure chamber.</p> |
