The invention below relates to a doctor blade device with an elongated doctor blade intended to operate continuously against a roll surface () and/or a cylinder surface () during scraping or wiping off material (IB) on the surface (), which doctor blade device () comprises a carrier beam () adapted to the length of the roll surface or cylinder surface, which carrier beam has a clamping arrangement () for the positioning of a carrier part (), arranged, in a groove in the longitudinal direction, to slidably carry the doctor blade (), wherein the carrier part () comprises a carrier blade (), a lip means () arranged at the carrier blade () and a spacer element () arranged between the lip means () and the carrier blade, wherein the carrier blade (), the lip means (), and the spacer element () are arranged, along a first long side edge of the carrier blade () between them, to form said groove () for slidable positioning in the longitudinal direction of the doctor blade () by support of the carrier blade (), the lip (), and the spacer element ().

Doctor blade device

A creping doctor device for the scraping off and creping of a running paper web from a rotating cylinder, comprising a holder device arranged to be able to support a continuous, or divided, longitudinally moveable doctor blade, which doctor blade is arranged to have a length that exceeds at least twice the length of said cylinder and is provided with a scraping surface and a contact line and/or contact surface, which contact line and/or contact surface is intended to bear against the jacket surface of said rotating cylinder at a certain linear load, said doctor blade comprising a supporting part and a wear part that is moveable in relation to the supporting part.

Method for the creping of paper

A device for regulating and cleaning an air port ( ) arranged in the wall ( ) of a furnace, especially a soda house furnace, comprises a cleaning arrangement ( ) and an arrangement ( ) for regulating the air flow through the air port, in which an air casing ( ) is arranged around the air port on the outer side of the furnace wall, in which a drum ( ) is arranged inside the air casing and air-tightly connected to the wall of the air casing located opposite to the furnace wall. An opening defined by at least a cover member ( ) of the regulating arrangement and at least one lateral wall of the drum is arranged with a restricted extension in the circumferential direction of the drum so as to achieve an air jet in towards and through the air port ( ).

Device for regulating and cleaning an air intake

Application apparatus for the coating of a travelling web ( ), comprising a support roll ( ) and a predosage roll ( &prime;), said rolls forming a nip between themselves through which the web is brought to travel, further comprising an application device ( ) by which sizing agent or coating agent ( ) can be transferred onto the web, and means ( ) for final evening of material applied onto the web, characterized in that the application device ( ) is designed in such a manner that it transfers directly onto the travelling web ( ) said material ( ) in a certain excess before entering the nip where predosage is provided before the subsequent and final evening of applied material.

Coating device and process for coating

Coating blade for applying coating material onto a travelling web (,), particularly coating liquid onto a travelling paper web, comprising a steel band (,), which, along the edge section (,) intended to engage the web (,), is provided with a wear-resistant coating (,). Said coating is constituted by a material which has a hardness according to Shore A of from about 30 to about 80.

Coating blade having a wear-resistant edge

Creping blade for the detachment of a travelling paper web from a dryer cylinder, said blade having an edge or tip section engaging said cylinder and being constantly hit by the traveling web during its detachment from the cylinder. The invention resides in the improvement of said edge or tip section being provided with a wear-resistant coating on a first part of said edge section hit by the web, the other part of said edge section engaging the cylinder being uncoated or coated with a non-wear-resistant material so that said other part is subjected to sliding wear. A recess is located in the side surface so that the wear land surface that contacts the cylinder remains essentially constant throughout the operative cycle of the blade.

Creping blade

Device for the application of a coating composition on a traveling web (,) comprising a transfer roll (,), a support roll (,) cooperating with the transfer roll (,), the traveling web being fed in a nip between said rolls, further comprising a gravure roll (,) intended for the transfer of an adapted quantity of the coating composition onto the transfer roll (,), and a device for passing of the web through said nip, characterized by a blade device (,) for the removal of excess of coating composition from the gravure roll (,), said blade device being arranged in trailing position in relation to the moving surface of the gravure roll (,).
