In a grooved drum with a working drum surface of metal consisting of a cylindrical inner drum on which at least one ribbon is helically wound, turn by turn, the radially outer boundary of which forms the working drum surface, the ribbon also forming axially extending circumferential grooves, adjacent turns of the ribbon are connected to each other in a form locking manner on their sides facing each other in the axial direction causing the adjoining turns to be immovably fixed relative to each other so that in the event of a break in the ribbon the turns will not give in to the circumferential tension force generated during winding and burst open.

In a roll for pressure treating webs of material comprising a stationary core which is surrounded by a rotatable hollow cylinder spaced from the core, and in which there are provided, between the core and the hollow cylinder, longitudinal seals and end seals which seal off a longitudinal chamber which extends between the core and the hollow cylinder on the side of the working gap and is filled with a pressure liquid, with discharge canals provided in the core for discharging leakage liquid from the space between the core and the hollow cylinder which remains between the core and the hollow cylinder on the side facing away from the working gap, an improved sealing arrangement, which includes a strip which extends along the hollow cylinder over the length of the longitudinal chamber following in the direction of rotation, the seal projecting at an angle from the core toward the longitudinal seal up to the inner circumference of the hollow cylinder and discharge canals opening in the region between the point where the strip is secured to the core and the longitudinal seal, is provided to reduce friction.

Apparatus for dyeing a continuously moving textile web which comprises means to apply a wetting agent to said web, means to apply pressure to said web to improve the penetration of said wetting agent, at least one means to apply dye to said web, including a container to hold dye, a rotating roller positioned partially in said container and adapted to pick up dye on its surface, a scraper having one end adjacent said rotating roller and the other end adjacent and above said web, said scraper being positioned to remove dye from said rotating roller to cause dye to flow upon the web, and means, such as a pair of rollers, to apply pressure to said web to improve dye penetration.

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.

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.

In order to obtain better heat transfer in a coolable roller with an inner supporting cylinder which consists of metal, and on which a tubular roller jacket is firmly disposed, the jacket consisting of plastic and having slots on its inner circumference, the inner cylinder is constructed so that it can be cooled from the inside and a pressure resistant heat conductor which is in heat conducting contact with the walls of the slots is disposed in the slots.
摘要:
A sealing arrangement for a roll consisting of a stationary core and a hollow cylinder surrounding the core with a spacing and rotatable thereabout, which includes a longitudinal seal made up of a seal carrier disposed in a slot in the core, the seal carrier itself forming a slot in which there is disposed a sealing strip made of a material having good gliding properties extending therefrom radially toward the inner wall of the hollow cylinder and pressed there against by the pressure of a pressure liquid.
摘要:
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.
摘要:
A roll with a revolving hollow roll and a stationary cross head which extends therethrough lengthwise, spaced a distance from the inside circumference of the hollow roll on all sides, has, in the space between the hollow roll and the cross head, a longitudinal chamber provided with a feed line for pressure liquid, divided by a sealing arrangement which comprises strip shaped longitudinal seals extending on both sides of the action plane of the roll, as well as transverse end seals. The transverse end seals are designed as gap seals, the gap surfaces of which are kept spaced from each other by separate precision antifriction bearings.
