Abstract: In a double-band or similar press the pressure on the mat that is being fed in is increased so rapidly as soon as this mat comes into contact with the heat-transfer surfaces that the outer areas of the mat harden under the great pressure, whereas the heat has still not penetrated into the interior of the mat. This results in an enhancement of the surface quality of the panel. As an example, to this end, a roller gap can be provided before the feed gap.

Abstract: A method and device for heating the pressure belt of a press, in which the press pressure is exerted by a gas-filled pressure chamber on the working run of pressure belt and heat transfer is increased by a high circulation rate of the pressure medium in pressure chamber, to create a situation in which a large quantity of heat can be transferred even in the lower pressure ranges. Steam is mixed with a gaseous pressure medium, e.g. air, before it enters the pressure chamber and the back of the pressure belt is exposed to the steam-air mixture in the vicinity of pressure chamber, whereupon the steam condenses wholly or partially on the colder back of the pressure belt in the zone adjacent to the entrance. The heat of condensation thus released results in intensive heating of the pressure belt in this zone and hence of the workpiece.

The roller bars, at the end faces thereof, are mounted in guide chains driven by entry sprockets. The entry and feed sprockets, which are fixed on the same axis, of the table and press ram are controlled in a synchronized manner and, in each case with the same radius, enclose both the roller bars as well as the link sleeves or the protective rollers in such a way that the center axes of the top and bottom roller bars are in alignment with one another in the pressure direction.

Abstract: A continuous press is provided wherein the elastic forces are conducted centrically from the centering bolts into the vertical Y--Y axis and the longitudinal center of the guide chain. An accumulation of unilateral forces on the brackets of the guide chain is thereby avoided. The elastic forces, which are set up in the bearing bolts by the linear displacements of the rolling bars and are at times considerable, are thus conducted centrically into the guide sleeves and thus as a force centrically into the guide chain. The forces thus do not occur as an eccentric load on the guide chains and, consequently, are incapable of causing the destruction of the guide chains even with a relatively high load.

Abstract: The wide, thin, revolvable, flexible, metallic casting belts are made to incorporate differential patterns of residual internal longitudinal tensile and compressive stresses. The two marginal areas are residually longitudinally stretched more than the main middle area straddled by these margins. This main middle area is used as a moving mold and is expected to contact molten metal. Thus, the treated belts have two marginal areas in a state of mild longitudinal compression straddling the main middle area in a state of mild residual longitudinal tension. During casting, when hot metal comes into contact with the main middle area of such treated belt, the main middle area expands. Because of the built-in differential compensating stresses, the stresses throughout such belt during casting advantageously become balanced or equalized across the whole belt width.
