ABSTRACT:
A continuously operating double band press for fabrication of laminates , chip- or fiberboard, plywood or the like has an upper endless press band and a lower endless press band wound over respectively two reversing drums rotatably supported in a rigid press stand. Pressure chambers are arranged at the inner sides of the press bands, which are bounded in vertical direction by pressure plates fastened in the press stand and the press bands and in horizontal direction by floating seals. A pressure produced by fluid agents acts in the pressure chambers. Elements are arranged in the pressure chambers provided with a body and projecting individual surface enlargement members. The projecting individual the surface enlargement members consist of a material having good thermal conductivity and protrude into the fluid pressure agent located in the pressure chamber and have a good thermal conducting contact with the body of the element.
