摘要： A doctor for a suction roll in a paper machine is intended to remove water from a suction roll. The doctor includes a doctor slat fitted against the surface of suction roll extending essentially over the entire width of the suction roll, as well as the doctor slat holder and loading devices. In the direction of rotation of the suction roll, there is a doctor blade, with a blade holder fitted to the doctor after the doctor slat. The doctor blade is arranged to remove the water lifted off the suction roll by the doctor slat.

摘要： In laminated, resin-impregnated doctor blades for removing water from a grooved belt in the press part of a papermaking machine, fibers of the belt-contacting layer are oriented in the direction of travel of the belt. The doctor blade so constructed exhibits greater adhesion to the belt, an improved water-removal capability, and greater durability, when compared with a doctor blade having randomly oriented surface fibers.

摘要： An apparatus for measuring wear of a doctor blade includes measuring members placed around the doctor blade for measuring at least one dimension of the doctor blade. The measuring members are arranged to permit longitudinal movement of the doctor blade between the doctor blade and the measuring members. In addition, measurement sensors are connected to the measuring members to obtain a continuous measurement result when the doctor blade or the apparatus is moved. The invention also relates to a method in the measurement of wear of a doctor blade and in controlling a paper machine.

摘要： An apparatus for doctoring a moving surface includes a blade holder component extending longitudinally across the moving surface and carrying a doctor blade. A support component is parallel to and supports the blade holder component. A first operating mechanism rotatably urges the doctor blade in a doctoring direction into contact with the moving surface, resulting in the doctor blade being acted upon by a reactionary thrust force in the plane of the doctor blade and a reactionary rotational force in a direction opposite to the doctoring direction. A pair of mutually opposed parallel guide rails are provided on one of the components, and rotatable rollers are spaced along the length of the other of the component. The rollers are in rolling contact and in mechanical interengagement with the guide rails to accommodate reciprocal movement of the blade holder component relative to the support component, and to resist both the reactionary thrust force and the reactionary rotational force acting on the doctor blade. A second operating mechanism reciprocally moves the blade holder component relative to the support component.

摘要： A beam with a continuous body (11) of a composite material has end pieces (13) fitted at each end of the body (11) and axle journals (12) fitted on the end pieces (13). Each axle journal (12) is supported on the frame constructions of the machine by means of a support construction (15, 20, 21, 30, 31, 100), in which there are bearing members (21, 31) fitted at a distance from one another in the longitudinal direction of the axle journal (12). The bearing members (21, 31) are fitted in bearing housings (20, 30), and a bending mechanism (40, 50, 60) is fitted in the support construction (15, 20, 30, 100), by which a torque is applied that bends the body (11) of the beam. The beam may support doctor blades, various measurement devices, induction devices, and coating devices.

摘要： In manufacturing a moving web, such as a tissue sheet, the web is transported at very high speeds, often in an unsupported manner, which can result in unstable operations regarding handling and winding of the web. This is particularly true in the region between the creping blade and the reel for a lightweight, low modulus tissue sheet that is characteristic of a high-quality, soft tissue basesheet. To provide an improved means of controlling the tissue web during manufacture and to improve the manufacturing rate, an apparatus and method of stabilizing the moving web that incorporates a creping blade foil, one or more aerodynamic sheet stabilizing foils, and a roll foil in a specific relationship to each other is disclosed. This method has been shown to improve the stability of a moving tissue web, allow for a higher rate of operation, and enable the production of softer tissue basesheets.
