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).

Twin wire former

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), or a forming roll (40). 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).

A wire part of a machine for the production of continuous fibrous material webs, especially a papermaking machine, includes two continuous wire belts which together form a twin-wire zone. At least one supporting element having a supporting surface is disposed in the region of the twin-wire zone. At least a part of the supporting surface provides a supporting region which supports a first wire belt on its inner surface and a second wire belt on its outer surface. At least one formation box is provided and is disposed in the supporting region. The formation box is designed in such a way that, in the region of the inner surface of the second wire belt in the formation box, pressure values can be adjusted from a reduced pressure to an excess pressure acting on the inner surface of the second wire belt. The formation box extends in the direction of movement of the wire part over at least a part of the supporting region.

A winder for winding a traveling paper web. Two king rolls form a winding bed for accommodation of a paper roll, and a revolving support belt loops around the paper roll on part of its circumference. The support belt is arranged between the two king rolls, and is backed by a backing element adapted to be forced on it. The support element features a support surface on which the support belt slides and whose radius is variable in accordance with the radius of the paper roll.

A winding device for paper or cardboard with at least two axis-parallel support elements for the sheet winding, which extend at least over the length of the sheet winding (T) and of which at least one is a carrier roll (2). The other support element has a rigid carrier (4), which guides the sheet winding over a sheath (7, 7') arranged in a rotating manner around the carrier or guided in a flexible tubing manner, and a carrying shoe (5, 5') combined with it and acting hydrodynamically with respect to sheath (7, 7'), which carrying shoe is provided with a concave pressure surface whose radius of curvature essentially corresponds to the maximum winding (T) including the sheath wall thickness, whereby carrying shoe (5, 5') can be adapted in its position to the size (position of the periphery) of the sheet winding (W') which is wound and present each time.

A doctor bar consists of two different circular disks that are clamped or fixed in some other way on a cylindrical carrier bar. Circular disks having a smaller diameter and made from elastic material alternate with circular disks that have a larger diameter and are made of a very wear-resistant material, specifically ceramic. The difference in the outside diameter makes for one-half the groove of peripheral grooves of the doctor bar that are formed between the various circular disks.
