摘要： A headbox, for example, in a pulp or board machine, is suitable for high basis weights which are over 400 g/m2 and for high fibre suspension consistencies which are in a range of 2-5%. The headbox has a turbulence part (1), into which a fibre suspension flows from a tube bank (2), and a slice part (3) which is situated after the turbulence part and from which the fibre suspension flows to a forming section of a fibrous web. The turbulence part (1) of the headbox has at least two passages (5, 6), which converge in the flow direction of the fibre suspension towards the slice part (3). In that connection, the fibre suspension flow is first fluidized in a tortuous turbulence passage part (11) and, after that, it decelerates in another widening deceleration passage (12).

摘要： A tissue sheet is made using a modified wet pressing machine in a modified wet pressing process employing an integrally sealed air press. After initial formation and conventional vacuum dewatering, the wet web is conformed to the surface contour of a relatively coarse fabric to give the web a textured surface. By creating a pressure differential across the web of at least 30 inches of mercury and an air stream through the web of at least 500 SCFM/in2, the air press noncompressively dewaters the wet web to a consistency of about 30 to about 40 percent prior to a heated drying cylinder. The web is dried to substantially preserve its three-dimensional, throughdried-like texture. The process provides a web having an exceptionally high degree of bulk and absorbency not expected in wet-pressed products.

摘要： An apparatus for loading fibers in a fiber suspension with calcium carbonate has a housing with an inlet and an accept outlet. A rotatable distribution member is positioned within the housing. A rotor and stator assembly is positioned within the housing radially outside of the distribution member. A toothed ring is interposed between the distribution rotor and the rotor and stator assembly. The toothed ring and the rotor and stator assembly define a gas ring therebetween. A reactant gas supply is fluidly coupled with the gas ring.

摘要： Method for improving the formation of a web material in a wire machine, including dispersing existing flocks in stock which is transported along a transport direction from an inlet box onto a plurality of wire sections which are arranged after each other along the direction of travel, counteracting the reformation of flocks in the stock on the wire by furnishing ultrasound energy as ultrasound waves with frequencies between 15 and 75 kHz to the stock on the wire sections. The ultrasound has a higher frequency within at least one section which is closer to the inlet box than a subsequent section further away from the inlet box, within which subsequent section the ultrasound has as lower frequency.

摘要： A method in a paper machine for transferring a paper web from a wet wire in a former section to a pick-up fabric or an equivalent transfer fabric of a press section, including the steps of forming a pick-up point on the wet wire and separating an edge strip from at least one edge of the web prior to the pick-up point by means of at least one cutting device. The method further includes separating the web from the wet wire and passing the web onto the pick-up fabric at the pick-up point. The method also includes applying a pressure difference to the at least one edge strip through the wet wire or the pick-up fabric at or after the pick-up point to cause the at least one edge strip to either follow the wet wire or become separated from the pick-up fabric after the pick-up point and to be placed in a broke system arranged beneath the paper machine.

摘要： A method and machine for the manufacture of a fiber web, in particular of a tissue web or of a hygienic web, in which the fiber web is formed on a soft clothing with fine pores and the clothing is guided over a surface subject to suction and in which the fiber web is transferred from a soft clothing with fine pores directly onto a TAD wire of a TAD drying apparatus. An optimum quality of the respective final product is achieved with an energy effort which is as low as possible, in particular, the energy effort required with vacuum generation in the dewatering of the fiber web is reduced.
