A press for exerting a pressure over an area in a longitudinal section of a sheet, particularly a press for producing wood chip board and similar materials, having two opposed pressure plates between which the sheet is passed, and which are braced against respective support structures provided on the outside, wherein the pressure is transmitted by a pressure medium to at least one pressure plate from the support structure associated with it through several pressure elements arranged at points lined up across the sheet in such a manner that a variable pressure profile across the sheet results.

Press for exerting a pressure over an area

In an arrangement in which a group of roller chains packed closely together, side by side, in a manner in which they can advance independently of each other, with the chains advancing parallel to each other in common plane in one area and the chains leaving the common plane at one point and thereafter following separate paths and then coming together again at an entry point for the common plane, guides are provided to prevent adjacent roller chains from running up on to each other as they return to the common plane.

Roller chain guide arrangement

An improved continuous press of the type having two rotatively driven endless conveyor belts forming opposed, substantially linear spans defining a press zone with support structures applying pressure through the travelling belts to work carried therebetween, in which a plurality of sets of individual roller chains closely following each other in longitudinal direction are disposed between the support structures and the conveyor belts.

Press for exerting flat pressure

Apparatus for producing pattern on advancing strips such as strips of textile and similar materials in which a roller rotates in a trough picking up a liquid such as a dye used for producing the pattern and carrying the liquid to a scraper blade slanted toward the strip of material with the scraper blade scraping off the liquid adhering to the roller which is then permitted to run down onto a strip moving therebelow. In accordance with the present invention, a plurality of movable channels are provided at the bottom end of the scraper plate, the channels being movable between one position in which the liquid is permitted to flow onto the moving strip and another position in which the liquid is directed to a catch pan from which it can be returned to the trough with means provided to oscillate the channels so as to produce a desired pattern on the strip.

Apparatus for producing patterns on advancing strips

A rapid load relief device to prevent fast build-up of pressure in a continuous press of the type having two rotatively driven endless conveyor belts forming opposed, substantially linear spans defining a press zone with press platens applying pressure through the travelling spans to work carried therebetween and in which a plurality of hydraulic cylinders or spindles are inserted between the press platens and rigid supports with pressure supplied to the cylinders through a pressure-controlling valve which is sensitive to the movement of the pressure platen to regulate the pressure in the cylinders maintaining a constant platen spacing in which means are provided which, upon sensing an excess pressure, immediately separate the press platens.

Rapid load-relieve device for continuous press

A safety device for avoiding excess pressure in a continuous press of the type having two rotatively driven endless conveyor belts forming opposed, substantially linear spans defining a press zone with press platens applying pressure through the travelling spans to work carried therebetween and in which a plurality of hydraulic cylinders or spindles are inserted between the press platens and rigid supports with pressure supplied to the cylinders through a pressure-controlling valve which is sensitive to the movement of the pressure platen to regulate the pressure in the cylinders maintaining a constant platen spacing in which the pressure-controlling valve is coupled to the press platen through a piston and cylinder arrangement having a pressure therein maintained so as to not exceed a pre-determined value whereby pressure in the hydraulic cylinders exceeding that pressure will cause the piston to yield and relieve the pressure.

Apparatus for avoiding an excess of pressure in a continuous press

In a continuous press having two rotatably driven endless conveyor belts forming opposed, substantially linear spans defining a pressing zone with press platens applying pressure through the travelling spans to work carried therebetween with anti-friction roller means interposed between the platens and spans, the anti-friction roller means being endless loops of rotatably unpowered roller chains forming a bed interposed between the platens and the belt spans with the roller chain spans extending longitudinally with respect to the belt spans and being transversely packed together with each chain individually free to travel independently with respect to the others and the belt span wherein the chains are comprised of units of at least two equal diameter rollers installed in a cantilevered manner on roller pins, the roller pins being linked together by a chain of flat interposed links with adjacent rollers in the direction in which they run of the same length and having their outer end faces situated in a plane which forms the outer delimiting surface of the chain.

Continuous press having improved anti-friction rollers

A continuous press has two rotatively driven endless conveyor belts forming opposed, substantially linear spans defining a pressing zone, press platens applying pressure through these traveling spans to work carried therebetween, and anti-friction means being interposed between the platens and the spans. Such a press is improved in that the anti-friction means is formed by a multiplicity of endless loops of rotatively unpowered roller chains forming a bed interposed between the platens and the belt spans, the roller chain spans extending longitudinally with respect to the belt spans and being transversely packed together, but each chain being individually free to travel independently with respect to the others and to the belt span. The chains are formed so as to not have a continuous link gap so that the overall path is free from transverse interspacing.
