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.
In an apparatus for exerting a flat pressure on a lengthwise section of an advancing strip such as a continuous press for the continuous production of panel materials being produced under pressure in which the strip is conducted between endless forming bands extending across the width of the strip and circulating in the direction in which the strip advances with pressure transmitted to the endless forming bands from the press platens applying pressure to said forming bands with means between said forming bands and press platens for transmitting pressure in an anti-friction manner, improved means for transmitting pressure in an anti-friction manner disposed between said forming bands and press platens comprising a plurality of independent roller chains transversely packed closely together and supported so that they can move forward in the direction of advancement of the strip and forming bands, each of said independent chains being individually free to travel independently with respect to the others and said forming bands, with each of said independent chains being formed of a plurality of linked units, each unit including at least two rollers supported on a roller pin with flat links lying in a plane perpendicular to the roller pin linking the units, the outside rollers of each unit being cantilevered on the roller pin, all rollers in a row in the direction of travel being of equal diameter and having their outer end faces situated in a plane which forms the outer limiting surface for the roller chain.
