20090025899 | Apparatus for Cleaning a Fiber Suspension for a Papermaking Process - An apparatus for cleaning a fiber suspension for papermaking of foreign substances contained therein, such as sand, metal parts, glass splinters, bark fragments and the like, by using a tubular, vertically aligned housing, which is constructed with an inlet for the introduction of the fiber suspension into this housing under pressure, also provided at its lower end with an outlet for discharging the foreign substances contained in the fiber suspension and at its upper end with an outlet for leading off the fiber suspension freed of the foreign substances. In this case, at least a portion of the housing, or the lower housing parts, or at least a casing that encapsulates the lower housing parts, are produced from a transparent or a see-through material, in particular from a transparent or a see-through plastics material. | 01-29-2009 |
20100154209 | Device for Releasably Fastening a Wire Foil in an Installation for Producing Paper - A device for releasably fastening a wire foil to a supporting strip in an installation for producing paper. The installation has a wire and wire foils that extend transversely with respect to the movement direction of the wire. The foils are situated at a spacing from one another in the movement direction of the wire and come into contact with the wire. Supporting strips for the wire foils are assigned to the wire foils and likewise extend transversely with respect to the movement direction of the wire. The wire foils or the supporting strips which are assigned to them are configured in their longitudinal direction with an undercut groove, and the supporting strips or the wire foils are configured with a spring which corresponds to the cross section of the undercut groove. It is possible for the wire foils to be pushed with play onto the supporting strips transversely with respect to the movement direction of the wire, with the result that, in their operating position, they are fastened releasably to the supporting strips. A clamping strip which extends in the longitudinal direction of the supporting strip and the wire foil is provided between the supporting strip and the wire foil, the displacement of the clamping strip in its longitudinal direction bringing about a transverse movement of the wire foil with respect to the supporting strip, as a result of which the wire foil is connected rigidly in its operating position to the supporting strip. | 06-24-2010 |
20100270396 | Apparatus for Spraying a Liquid - An apparatus for spraying a liquid, such as a cleaning liquid or a lubricating liquid, onto a wire or onto a felt in a plant for paper production. The apparatus has pipeline for supplying the liquid and spray nozzles for ejecting the liquid. A shaft with a cleaning device for the spray nozzles or for the inner wall of the pipeline is disposed within the pipeline. The shaft includes a cylindrical sleeve which has a slotted guide and a thread and is arranged in a housing which adjoins the pipeline, the thread interacting with a control spindle and, furthermore, a bolt or the like being provided which can be adjusted transversely with respect to the housing and projects into the slotted guide in a first position, as a result of which, during a rotation of the control spindle, the shaft is displaced in the longitudinal direction of the pipeline. Here, a second bolt or the like is provided, by which the control spindle can be coupled to the cylindrical sleeve in terms of its rotation, as a result of which, after adjustment of the first bolt or the like out of the slotted guide, the shaft can be rotated by the control spindle. | 10-28-2010 |

20150118446 | TEARING TAPE FOR SEVERING A PAPER WEB IN A PAPERMAKING INSTALLATION - A tearing tape which is composed of paper for severing a paper web which moves from a system for producing paper and is wound up on drums, in order as a result to make it possible for it to be wound onto an empty drum. Here, the tearing tape, in cross-section, has a central tape part and two lateral tape parts. The central tape part has a thickness that is at least 1.5 times greater than a thickness of the lateral tape parts. | 04-30-2015 |
20150232278 | INSTALLATION WITH AT LEAST ONE CONTINUOUS CONVEYOR BELT FOR CONVEYING MATERIALS AND PRODUCTS - A conveying installation has least one endless conveyor belt guided via a plurality of rollers along a leading belt run for conveying material or products and a returning belt run, particularly for manufacturing a paper web with a wire belt or felt belt. At least one of the rollers has an adjustable mounting for adjusting and correcting a direction of movement of the conveyor belt. A tensioning unit for detecting and controlling a tension of the conveyor belt has a pressure-measuring apparatus disposed at the adjustable mounting. A movement correction unit for detecting deviations of a direction of movement of the conveyor belt from a correct movement and for correcting the movement includes a sensor that is disposed to monitor a lateral periphery of the conveyor belt. A sensor output of the sensor is used for adjusting the adjustable mounting of the one of the rollers. | 08-20-2015 |
