摘要： An installation for producing a fibrous material web, in particular a long-fiber paper or wet nonwoven web, contains a binder wire section having a binder wire for applying an aqueous binder to the fibrous material web, and a dryer section having a dryer fabric for drying and consolidating the fibrous material web. The binder wire section and the dryer section are arranged at a distance from each other, so that the fibrous material web is led from the binder wire to the dryer fabric in a free draw. At least one air extraction device is arranged at the edge of the installation in the region of the distance between the binder wire section and the dryer section.

摘要： A method for determining the dryness of a fibrous web, in particular a tissue web, during the production of the fibrous web, is carried out in a machine including a drying cylinder, in particular a Yankee cylinder, to which at least one, preferably two, dryer hoods are assigned, and a reel-up for winding up the fibrous web. The determination of the dryness of the fibrous web is carried out before the drying cylinder on the basis of measured values which describe the following variables: the amount of solids in the fiber web at the reel-up, the amount of water in the fiber web at the reel-up, and the amount of water which is evaporated in the dryer hood or hoods. A method for controlling or regulating a machine for producing a fibrous web, a computer program and computer program product are also provided.

摘要： A belt conveyor has at least one drum. The drum has a drum axle and a drum body with a drum shell and drum bases. The drum axle is mounted on the two sides by way of two bearings. A force measuring device and/or an accelerometer are arranged on the drum axle on the two sides. The sensors which are arranged on the two sides are preferably arranged between the drum body and the bearing outside the drum body. The sensor signals can be transmitted wirelessly by way of a telecommunications device which is assigned to the sensors.

摘要： A cylindrical screening device including a plurality of profile bars, in which a number of ring shaped bar holders are arranged perpendicular to a cylinder axis and spaced apart from one another, or bundles of a number of bar holders spaced apart from one another are provided on the inside or the outside with open-edged recesses. The shape of the recesses correspond in a substantially complementary manner to that of the feet of the profile bars. The profile bars are inserted into the recesses, parallel to one another and parallel to the cylinder axis, wherein an outer bar holder is in each case arranged in the region of a respective face-side end ring of the screening device. The attachment of the end ring is simplified in that the outer bar holder is detachably connected with the end ring.

摘要： An applicator head for a curtain applicator for coating a continuous material web with liquid or pasty application medium. The applicator head has an outlet edge extending substantially over the width of the applicator head. The application medium passes out of the applicator head in a free-falling curtain. A rinsing device allows the outlet edge to be supplied with a flowing gaseous rinsing medium. There is also described a method for coating a continuous material web by way of such a curtain applicator. The application medium passes out of the applicator head in the form of a free-falling curtain and subsequently comes into contact with the material web. The region of at least one of the outlet edges can be supplied with a flowing gaseous rinsing medium.

摘要： A press cover for a press roll or a transport belt has at least one polyurethane-containing layer. The polyurethane is obtainable by reaction of i) a polyol component, ii) an isocyanate component, and iii) a component containing at least one crosslinker. The polyol component is composed of mutually different structural units having the general formula —O—R1—X—R2—O— in which all of R1 and R2 independently of one another are identical or different and are linear or branched C1-C20 alkylene groups. Groups X are identical or different and are selected from bond, O, C(O)—O, and O—C(O)—O. At least 70 wt % of the structural units meet the following criteria: a) at least 80% of X are O—C(O)—O and the remainder are O or C(O)—O, and b) the average chain length of R1 and R2 is 8 or more carbon atoms, and c) at least 50% of R1 and R2 are independently of one another a linear or branched C8-C12 alkylene group.

摘要： A method for monitoring the state of a redox flow battery system that includes at least two battery modules connected in series. The method includes the following steps: S1: switching at least one battery module out of the series circuit; S2: discharging at least a partial volume of the electrolyte of the at least one battery module that was switched out of the series circuit in step S1, a potential difference being repeatedly detected, the potential difference being formed between a first potential of the negative electrolyte and a second potential of the positive electrolyte of the at least one battery module that was switched out of the circuit; S3: determining, from the potential difference values detected in step S2, the state of health of the at least one battery module that was switched out of the series circuit in step S1.
