摘要： The present invention relates to a method for removing water from a movable roll jacket surface in a wet section of a paper-making machine, which roll jacket surface preferably belongs to a flexible roll jacket in a shoe press, said method comprising the following steps: arranging a spray device next to the roll jacket surface, making available a collecting device which is provided with an opening and collects liquid, moving said roll jacket surface past said spray device, applying a medium onto said roll jacket surface with the aid of said spray device, and collecting liquid in said liquid-collecting device. The invention is characterized in that said medium is sprayed with high kinetic energy onto said roll jacket surface to follow a fluid stream rebounding from the roll jacket surface, so that the liquid is conveyed to said liquid-collecting device.

摘要： A shoe roll (1) of a shoe press is disclosed for use in a paper-making machine, the shoe roll comprising a blanket, or an endless belt, which houses a shoe assembly that in cooperation with an external backing roll forms an extended nip proper and the shoe press including an oil circulation piping system (10, 11) performing the removal of oil from the interior of the shoe roll (1) to an oil trap during the running of the machine, whereby the piping system also comprises a suction fan connected thereto. The invention is implemented by way of connecting to the oil circulation piping (10, 11) an oil siphon (9) adapted movable along the blanket in the interior of the shoe roll (1) so that the excess oil can be removed by means of the siphon during the time the roll is stopped from the interior of the blanket by a pressure differential generated by of the suction fan.

摘要： A vibration-minimizing suspension mechanism for a press roll is provided. The press roll and an opposing roll each having a rotational axis and cooperate to form a press nip adapted to impart a linear load on a fiber web passing therethrough. The linear load is oriented through the rotational axes of the press roll and the opposing roll. As such, the suspension mechanism comprises a suspension arm having opposed ends and a medially-disposed pivot, wherein the press roll is rotatably engaged at the rotational axis thereof with one of the opposed ends of the suspension arm. The suspension arm is further pivotably and adjustably mounted at the pivot so as to allow the pivot to be adjusted in substantially parallel relation to the linear load. The adjustability of the pivot thereby allowing a mounting line along the suspension arm, the mounting line being defined by the pivot and the rotational axis of the press roll, to be maintained in substantially perpendicular orientation to the linear load to thereby minimize vibration in the press roll.

摘要： The present invention is a method for maximizing water removal from an absorbent web in a press nip. The present invention uses a pressing unit having a blanket with a void volume and with a pressure profile that maximizes water removal in the press section or on the Yankee dryer of a paper machine. The pressure profile of the pressing unit according to the present invention has a very steep pressure drop at and/or following the exit of a pressure distribution curve in order to maximize water removal by minimizing rewet of the web. The improved pressure profile according to the present invention results in increased water removal and/or improved line speed. The void volume further increases water removal and/or improves line speed.

摘要： A web of tissue is formed in a crescent former, followed by an air press for water removal in the pressing section, passing onto a Yankee dryer. A headbox injects stock between upper and lower dryer fabrics brought together on a breast roll. The fabrics move over vacuum boxes, and the web is heated with steam and passed between an upper pressure box and a lower vacuum box forming an air press which dewaters the web. A sheet transfer pickup vacuum box holds the sheet to the upper fabric as the lower fabric diverges from the upper fabric. A pressure roller transfers the web onto a Yankee dryer. The fabrics are cleaned on vertical runs before returning to the breast roll. A second upper fabric or transfer fabric operating at a lower speed then the first can be used to form a rush transfer between the forming fabrics and the Yankee dryer which increases web bulk and absorbency. Instead of a second fabric, a vacuum pressure roll may perform the rush transfer between the lower forming fabric and the Yankee dryer. The lower fabric may be divided into two fabrics, and the second fabric which passes through the air press, can be used to mold a texture into the web. The rush transfer and the molding fabric may be combined in one machine. A twin wire former may be used instead of a crescent former in each of the above configurations.

摘要： Method of producing a paper having a three-dimensional pattern of alternating raised and recessed portions, which has been provided in connection with impulse drying, at which the wet paper web (10) is passed through at least one press nip (12) comprising a rotatable roll (13) which is heated and that the paper web during the passage through the press nip is given a three-dimensional pattern of alternating raised and recessed portions either by means of a patterned wire, band or belt and/or by a pattern on the heated roll (13) and where said pattern is pressed into the paper web against a counter means (11, 14). The wet paper web before said press nip is exerted to a creping- or other compacting procedure which foreshortens the length of the paper web. The invention also refers to a paper produced by the method, said paper having a high extensibility.
