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.

The papermaking machine has a wet end section, a press section, a drying section and an applying device for applying a medium to a moving web of material. The wet end section includes a twin wire area having a first wire and a second wire wherein the web of material is formed and positioned between the two wires and separated from the two wires before moving to the press section. At least one wet end section applying device is positioned on one side of at least one of the first wire or the second wire within the twin wire area and facing away from the web of material positioned on the wires. The press section of the papermaking machine has a first press element and at least one press section applying device facing directly toward the web of material. The method includes forming a web of material in a twin wire area of a wet end section of the papermaking machine, applying at least one first medium with at least one wet end section applying device to at least one side of the web of material within the twin wire area of the wet end section of the papermaking machine, moving the formed web of material to the press section of the papermaking machine, and applying at least one second medium to the formed web of material with at least one press section applying device after the web of material passes a first press element of a press section of the papermaking machine.

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.

摘要： A paper machine forming section with two wire forming units. One of the two forming units is a twin wire web forming unit having a headbox, two wire loops arranged in sandwich-like manner and a drainage element for each of the wire loops. The first web-forming unit has a first section including a curved suction drainage element or roll in the first lower wire loop; a second section with opposing drainage ledges, wherein the drainage ledges are stationary on the upper side and the drainage ledges are developed resiliently pressable on the bottom side; the drainage ledges of the upper and lower sides are arranged staggered with respect to each other in the direction of travel of the wire, and at least the ledges of the upper side are developed with suction; a third section which has at least one suction wire separating element on one side. The second web-forming unit is a hybrid former with a single wire. The guide rolls for the second wire of the first former and for the wire of the second former guide them on a joint wire path where the multilayer web is transferred to the wire of the second former. There is a headbox associated with the wire of the second former. A respective backwater circuit collects water and materials drained from each of the forming units and returns them to the respective headboxes.

摘要： In a twin-wire former for the production of a paper web, two wire belts (11 and 12) together form a twin-wire zone which is divided into three sections (I, II and III). In the first section (I) the two wires (11, 12) travel over a curved forming shoe (16). They form there a wedge-shaped inlet slot (15) with which a headbox (10) is directly associated. In the second section (II), several resiliently supported strips (27) rest against the lower wire (11) and between each of said strips (27) a rigidly mounted strip (28) rests against the upper wire (12). In the third section (III) both wire belts (11, 12) pass over another curved forming shoe (23).

摘要： A first endless felt belt (43) which absorbs water from the belt (9) passes through a first press nip (1) having a stone roll (42C) 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). One side of the web comes into contact with the stone roll (42C) in the first press nip (I) and the other side of the web comes into contact with the water impermeable elastic press element (53) in the second press nip (II).

摘要： A sorting apparatus has a first casing section (1) with a larger diameter and a second casing section (2) with a relatively smaller diameter, which casing sections are generally aligned in series. A rotor (6) has rotor parts which are coordinated with each casing section and appropriately adapted. An impeller rotates in a churning space (5) of the first casing section (1) and a drum type rotor section (9) in the second casing section (2) supports sorting elements (16), which rotate in a strainer space (12) formed by a cylindrical strainer basket (11). This provides both despeckling and sorting in the machine, and separates the rejects with a high solid content.

摘要： A sorter for paper pulp suspension including a rotationally symmetrical wire cage and a rotor supporting a plurality of vanes for rotating about the interior of the cage for moving suspension through the wire cage, the vanes being non-uniformly spaced. An annular pulp chamber surrounds the screen for collecting the pulp. A suspension outlet at the bottom of the pulp chamber receives the pulp from the pulp chamber. The pulp chamber extends axially beyond the lower end of the wire cage. An annular damping chamber surrounds the lower end of the pulp chamber and flow from the pulp chamber to the pulp outlet is past the damping chamber. The damping chamber develops a pool of the suspension in it. A pressurized gas cushion above the pool of suspension in the damping chamber controls the level thereof and damps the motion of the pulp in the pulp chamber.
