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

Pressure treatment apparatus for continuous web treatment includes a drum and a belt surrounding the drum almost completely with both drum and belt being movable with the web disposed in between. A pair of essentially semi-cylindrical sleeves are disposed about the belt as a supporting surface with a friction-reducing means, such as interconnected rollers, between the sleeves and belt to transfer force. The sleeve ends are spaced apart at two sides to permit passage of the web and belt while at the same time being urged together of both sides to impart a tensile force in the sleeve. This tensile force serves to exert a uniform pressure on the moving web substantially over the entire surface of the drum with the forces contained in a closed system and not loading the drum bearings.

Apparatus for the continuous pressure treatment of a web

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.

Roller chains for a continuous press

A grooved roller such as those used in the paper industry in which a plurality of grooved rings are heat shrunk onto a cylindrical core in a manner which provides ease of manufacture and avoid possibilities of premature contact of the outer rings with the cylindrical core.
