摘要： A first endless felt belt (43) which absorbs water from the belt (9) passes through a first press nip (1) and a similar second felt belt (57) passes through a second press nip (II). The arrangement is such that the web (9) is continuously in contact with at least one transport means (for instance, with one of the felt belts). In both press nips (I, II) the web (9) is in contact with an endless elastic press element (for instance, press belt or press shell) the water absorption capacity of which is less than that of the felt belts (43, 57). It is essential that two endless elastic press elements which are independent of each other, namely a first and a second press element (47, 53) are present and that the one side of the web comes into contact with the first press element (47) in the first press nip (I) and the other side of the web comes into contact with the second press element (53) in the second press nip (II). The press section has neither a stone roll nor a suction press roll.

摘要： Press section for drainage of a fibrous material web that includes a shoe press roll, a cylindrical counter roll, at least one nip, a first nip of the at least one nip formed by the shoe press roll and the cylindrical counter roll, and at least one press felt. The at least one press felt is disposed on each side of the fibrous material web. The at least one press felt travels through a last nip of the at least one nip where the at least one press felt is separated from the fibrous material web and conveyed away after leaving the last nip. The drainage capacity and the reliable guidance of the fibrous material web are improved.

摘要： A device for the sectional supply of pulp suspension to a headbox of a papermaking machine includes a plurality of main inlet lines from a pulp suspension distributor which are distributed over the width of the machine. A throttle is provided in at least one main inlet line. Downstream of the throttle, in at least one of the main lines, a subsidiary line for conveying a subsidiary stream of liquid, such as a pulp suspension or water, is connected to the main inlet line and disposed at an angle to the main inlet line. This angle between the main pulp stream and the subsidiary stream is chosen so that a small change in the rate of flow of the subsidiary stream will cause a large change in the rate of flow of the total stream (main pulp stream+subsidiary stream) directed in the same direction or in the opposite direction of the stream.

摘要： The invention is directed to a paper machine for the production of a fiber web, including a headbox for forming the fiber web. Disposed adjacent the headbox is either a dewatering unit, e.g., a dewatering cylinder, a double wire former or a four-drinier wire section. Also provided are at least one press unit for dewatering the fiber web, a tissue drying cylinder for finish drying the fiber web, a device for fiber web pickup from the tissue drying cylinder (Yankee cylinder), e.g., a creping doctor or a Clupak device, and a carrier belt for carrying the fiber web. At least one of the press units is configured as a shoe press for drying the fiber web, and includes a device for immediately separating the fiber web from a press felt after at least one press pass. The belt is preferably water impermeable, and an adhesion force between the water impermeable belt and the fiber web is greater than an adhesion force between the press felt and the fiber web.

摘要： A coating apparatus, for applying a coating substance to a paper web, has a chamber from which the coating substance is supplied via a slit type mouth communicating with an applicator space which is defined by the paper web and a doctor blade element. At the web, on the side of the applicator space from where the paper web enters, a throttling passage is formed by a back-pressure element in such a manner that a stream of excess coating substance issues from the applicator space via the throttling passage and abruptly separates from the web and in so doing flows away from the web predominantly as a film thereby preventing completely or almost completely the admission of air into the applicator space by the air boundary layer adjacent the moving web.

摘要： In a paper making machine for manufacturing a material web (10), such as in particular a paper or cardboard web, the material web (10) to be manufactured is transferred on the surface of a transfer means (24) to a take-off position (30) in the region of which a preferably air-permeable belt (32) having an at least substantially open surface is guided over a take-off roll (34) or the like and takes off the material web (10) from the surface of the transfer means (24). A pressing gap (36) extended in the web running direction (L) is formed at the take-off position (30) with the surface of the transfer means (24, 60) facing the material web (10) being deflected in the region of the extended pressing gap, while forming an at least substantially concave depression (38), and also being pressed by a pressing force intentionally generated in the region of this deflection against the take-off roll (34) in order to thereby assist the take-off of the material web (10) from the surface of the transfer means.
