Abstract
A compression device comprising two continuously circulating belts in operation, between which a layer of material has to be conditioned under pressure, particularly a compression device for compressing a mixture of fibers or fibrous material and synthetic resin at high pressures. The opposite runs of the belts are supported such that material is compressed by supporting bodies in which recesses are provided, into which in operation pressurized fluid is fed, which fluid can flow out of the recesses concerned only through the gap between a belt and the portion of the supporting body surrounding the recess, so that in normal operation this outflow of fluid produces a fluid film between the belts and the portions of the supporting bodies surrounding the recesses.
Claims6
In a compression device comprising two continuously circulating belts between which a layer of material is to be conditioned under pressure, the improvement comprising:
- a pair of supporting bodies mounted on said device, between which both said belts pass in spaced-apart relationship, thereby defining a space for conditioning said material between said belts;
- each of said supporting bodies having
- a plurality of first recesses facing a respective belt and defining pressurized fluid sources,
- a plurality of second recesses facing a respective belt and defining fluid discharge means, and
- unobstructed gaps between the respective belts and the portions of said supporting bodies between recesses;
- whereby fluid can flow out of said fluid sources, through said gaps, and into said discharge means, in order to maintain a fluid film between said moving belts and said portions of said supporting bodies between recesses.
