According to the invention, the two extruders (200, 300) are superposed and arranged on either side of a horizontal plane P extending at the level of the guide rollers (62, 63).

A calender stack including at least two rollers between which a nip can be formed. The ends of the rollers are supported in rotary fashion in bearings and one of the rollers is stationary and at least one other roller is embodied as an advancing roller and has a first adjusting system by which it is possible to move the bearings of the advancing roller, thus changing the nip. The advancing roller has a respective adjusting system on each of its two bearings and associated with each first adjusting system, a second adjusting system is provided, by which it is possible to adjust an axial offset of the advancing roller relative to the stationary roller.

A method for producing a rubber composition include a mixing step, a drying step, and a dispersion step. In the mixing step, an aqueous solution that includes at least one of oxycellulose fibers and cellulose nanofibers is mixed with rubber latex to obtain a first mixture. In the drying step, the first mixture is dried to obtain a second mixture. In the dispersion step, the second mixture is tight-milled using an open roll to obtain a rubber composition. The rubber composition does not include an aggregate that includes at least one of the oxycellulose fibers and the cellulose nanofibers, and has a diameter of 0.1 mm or more.

A method and device for operating a rolling device for manufacturing an electrode sheet. The rolling device including a rolling mill for forming a material film for the electrode sheet, which includes a roller pair and includes an application roller which is separate from the roller pair or is a part of the roller pair. The application roller being supplied with a substrate for the electrode sheet, the rolling mill having a film forming gap, which is formed by the roller pair, which outputs a quantity of material and which produces the material film therefrom. The material film being applied to the application roller and being transferred from the application roller to the substrate. The material film having a grammage and a film thickness, the grammage and/or the film thickness being regulated to a setpoint value, and the rolling device being controlled depending on the grammage and/or the film thickness.

A rolling assembly, including at least one roll pair with two cooperating rolls and a safety device. The safety device includes a hydraulic accumulator and a measuring device. The hydraulic accumulator includes an accumulator with a first and second accumulator chamber. A hydraulic fluid is disposed within the first accumulator chamber. A compressible gas is disposed within the second accumulator chamber. The hydraulic accumulator includes a moveably arranged separating member separating the first accumulator chamber from the second accumulator chamber. The roll pair has a working position and a safety position. A radial distance between the rolls is larger in the safety position than in the working position. The hydraulic accumulator is configured to move the roll pair from the working position to the safety position. The measuring device is configured to continuously detect a position of the separating member within the hydraulic accumulator.

An improved adjustable-angle pressing or nip roll is distinguished, inter alia, by the following features: the angle adjusting device comprises a double-armed lever, the moving device is constructed in such a way that, via this, a pivot axis of the double-armed lever can be adjusted relative to the process roll, and the angle adjusting device comprises, for the double-armed lever, a stop which acts at least on one side, in such a way that, in the case of further force loading by the force actuating unit, a pressing force can be generated which acts on the pivot axis of the double-armed lever and via which the pressing or nip roll can be pressure-loaded onto the roll shell of the process roll with the material web being guided through between the two rolls.

Disclosed is a resin impregnation apparatus. The apparatus includes: a resin supply unit for supplying a resin having a predetermined viscosity downwards; a film formation unit provided at a lower side of the resin supply unit and configured to form the resin supplied from the resin supply unit into a film shape while the resin passes between a pair of rollers spaced apart from each other. The apparatus further includes a fiber supply unit for unwinding a reinforcing fiber and bringing the reinforcing fiber into contact with the film-shaped resin so that the resin is impregnated into the reinforcing fiber to form a resin-impregnated reinforcing fiber.

A system for making a nonwoven nonwoven spun-bond or melt-blown fabric has a spinneret for spinning fibers or filaments, a cooler downstream of the spinneret for cooling the spun fibers or filaments, a stretcher downstream of the cooler for stretching the cooled fibers or filaments, and a conveyor downstream of the stretcher. The stretched and cooled fibers or filaments are deposited as a nonwoven web on the conveyor. Sensors measure input parameters at the spinneret, at the cooler, at the stretcher, and/or at at least one diffuser or at the conveyor. An evaluating unit for determining an output parameter from the measured input parameter with respect to a predetermined reference parameter.

A method and configuration for automated operation of a two-roll mill. Also provided is a method for continuous or semi-continuous operation of a two-roll mill.

The present invention belongs to the technical field of control for rolling mill vibration, and particularly relates to a control device, system and method for vertical-horizontal coupling vibration of a corrugated rolling mill. The control device includes a housing; a vibration-absorbing container is arranged in the housing; a steel ball particle group is placed in the vibration-absorbing container; a left side of the vibration-absorbing container is connected with one end of a return spring; the other end of the return spring is fixedly connected with a third base; the third base is fixedly mounted on a third sliding block; and the third sliding block is slidably arranged on a third linear guide rail.
