摘要： Regulation method in a paper machine for controlling the variation of the basis weight of a paper web in the machine direction in which the basis weight profile of the web is measured by means of a measurement device and a basis weight regulation system receives a signal of the measurement of the basis weight from the measurement device and generates a regulation signal for controlling the flow of thick stock passed into a short circulation circuit in the paper machine by a basis weight valve and/or a regulation pump. The variation of the basis weight in the machine direction in the paper machine is controlled, besides by the short circulation circuit of regulation, also by a substantially faster second circuit of regulation which comprises one or more actuators for controlling the flow rate of the dilution water flow in the dilution profiling system of the headbox and/or the consistency of the dilution water flow across the entire width of the paper web.

摘要： The present invention relates to a method for controlling a papermaking machine/board machine/tissue machine or the like, which papermaking machine/board machine/tissue machine or the like includes basic unit assembly groups, such as a headbox, a wire section, a press, a drying section, a coating unit, a finishing machine, etc. The machine control system of the papermaking machine/board machine/tissue machine or the like comprises a central processing unit (e.g. a unit for control room, alarm and other such functions), one or more process control units, and one or more input/output units, which are connected by control cables to the controlled units or actuators. In the method the process control units and/or input/output units of the machine control system are located in a mechanical machine part in connection with basic unit assembly groups of the papermaking machine/board machine/tissue machine or such. The invention also relates to an integrated machine control module in the machine control system of a papermaking machine/board machine/tissue machine or such. The integrated machine control module comprises an internal cabinet, wherein the process control units and/or the input/output units of the machine control system are located. Said internal cabinet equipment is arranged for monitoring ambient conditions as well as equipment for removing stresses caused by ambient conditions in such a way that the integrated machine control module can be located in ambient conditions existing in connection with basic unit assembly groups of the papermaking machine.

摘要： A method and an equipment for regulation of the initial part of the dryer section in a paper machine. Moisture is removed from the paper web in the press section (10) and the paper web is dried in the dryer section (R). The paper web is dried against heated faces of drying cylinders (20). The surface temperatures of the first drying cylinders (20) in the dryer section (R) are measured. The dry solids content/moisture content of the paper web (W) and the temperature of the paper web (W) before said first drying cylinders (20) are measured. In view of producing the desired running situation, based on the measurement results obtained, the surface temperatures of said first drying cylinders (20) and/or the dry solids content/moisture content and/or the temperature of the paper web (W) before said first drying cylinders (20) is/are regulated.
