An elongated planar or profiled component for a manufacturing machine of a fibrous cellulosic web, such as paper, board or tissue web, is at least partially formed from a composite material having a continuous polymer matrix, and reinforcing inorganic fibers embedded in the continuous polymer matrix. The continuous polymer matrix is biodegradable and the reinforcing inorganic fibers are biodegradable glass fibers. A method is disclosed for recycling elongated planar and/or profiled components used for manufacture of a fibrous web.

A dewatering box cover including a main body having a leading edge, a trailing edge opposite the leading edge, a first side edge, a second side edge opposite the first side edge, a top surface, and a bottom surface and a plurality of sets of holes formed within the main body. The holes within each set are aligned with one another along an imaginary line that is angled from 30° to 70° relative to horizontal and the holes extend downwards from the top surface of the main body towards the bottom surface of the main body at an angle of 20° to 45° relative to vertical.

A dewatering box cover including a main body having a leading edge, a trailing edge opposite the leading edge, a first edge, a second side edge opposite the first side edge, a top surface, and a bottom surface. A first slot is formed within the main body having a first portion and a second portion angled relative to the first portion so as to form a V-shape. A plurality of second slots are formed within the main body at both sides of the first slot. The second slots and the first and second portions of the first slot extend from the top surface to the bottom surface of the main body at an angle relative to horizontal of 30° to 70° and at an angle relative to vertical of 20° to 45°.

A dewatering device has a dewatering box and a plurality of dewatering strips. A contour of at least one dewatering strip changes over its length. There is also described a machine for the production of a fibrous web, such as a paper, cardboard or tissue web, with a dewatering device of this kind, and to the use of the latter in a machine of this kind.

A system is disclosed for removing fluids from a felt in a paper making process. The system includes a vacuum source for providing a vacuum adjacent a vacuum plate against the felt is moved, and crescent shaped openings in the vacuum plate through which the vacuum is applied to the felt for the removal of the fluids.

A system is disclosed for removing fluids from a felt in a paper making process. The system includes a fluid in a reservoir that is adapted to permit a surface of the fluid to contact an underside of the felt.

The invention relates to a suction device (15) for use in a papermaking machine (1). The suction device (15) has a length (L) in the machine direction that extends from a first end (16) to a second end (17). The suction device (15) further has a surface (18) which, during use of the suction device (15) in the papermaking machine, will be facing a permeable fabric (4, 6) passing the suction device during operation such that this surface (18) is a fabric-facing surface (18). The fabric-facing surface (18) has a first part (19) which begins at the first end (16) of the suction device (15) and extends towards the second end (17) but ends before the second end (17) of the suction device. The first part (19) of the fabric-facing surface (18) is formed by a plurality of planar surfaces (23) which constitute end surfaces of a plurality of solid elements (21) and lie in the same plane such that, during operation, they can contact a fabric (4, 6) gliding over the fabric-facing surface (18) along a straight path. The solid elements (21) are separated from each other along the length of the suction device (15) such that channels (24) are defined between the solid elements (21), and the suction device (15) can be connected to at least one source of underpressure (26, 27) in such a way that the at least one source of underpressure (26, 27) is in communication with the channels (24) between the solid elements (21) such that, when the suction device (15) is used and the permeable fabric (4, 6) runs over the fabric-facing surface (18), the suction device (15) can act on the permeable fabric (4, 6) through the channels (24) and draw the permeable fabric (4, 6) towards the fabric-facing surface (18). The first part (19) of the fabric-facing surface (18) is followed by a second part (20) of the fabric-facing surface (18). The second part (20) of the fabric-facing surface (18) is a surface (33) formed as an end surface of a final solid element (22) which does not lie in the same plane as planar surfaces (23) belonging to the first part (19) of the fabric-facing surface (18) but is spaced from that plane such that, when the permeable fabric (4, 6) passes over the suction device (15), the permeable fabric (4, 6) will not contact the final solid element (22). The final solid element (22) is sepa

A drainage foil for use in an installation for producing a paper web with a fabric belt, which can be moved over a multiplicity of drainage foils oriented transversely to a direction of movement. A surface of the drainage foil is formed with a defined profiling, which has elevations and/or depressions. The vertical extent of the profiling is at least 0.1 mm.
