摘要:
In a reel change in the reeling process of a fiber material web, the fiber material web (W) running to a reel that is becoming full is changed to run around a new reeling core (2) brought to a reel change position in such a way that the web is made to adhere onto the surface of the new reeling core (2). The web (W) is made to adhere onto the surface of the reeling core (2) by a change in the properties of the material on the surface of the reeling core (2). The material is a combination of an adhesive area (6a) on the surface of the reeling core and a protective layer (6b) on top of the adhesive area, and the properties of the material are changed by removing the protective layer (6b).

摘要:
A method and a system to control a reeling profile of a material web reel (30), when, in the forming of a material web reel (30), a web is reeled around a reeling core and when in an adjustment of CD-directional profiles of the web reel, profiling devices (8) have been applied. For adjusting quality profiles and reeling profiles of the web, profiling devices are managed with the help of profile measurings of the roller nip and/or of the profile measurings of the reel (30), which are obtained from the reel-up (2). A measuring device (40) for a measuring of a CD-directional hardness profile of the fiber web reel includes a measuring head (43), which is connected with a loading means (41, 42), which loads the measuring head against the fiber web reel. The motion course of the measuring head is linear.
摘要:
A device for cutting a web with at least two cutting members for cutting/cross-cutting the web in the cross-direction and producing a cross-cut. The cutting members having a common actuator which moves the cutting members in directions apposite to each other in the cross-direction of the web.

摘要:
The invention relates to a measuring roll for a fibre-web machine, which roll has a shell on whose surface a sensor is arranged, and which roll is coated with a coating layer proper. The roll comprises at least one protective coating layer placed under the coating layer proper and on top of the sensor in such a way that when the coating layer proper is replaced, the protective coating layer remains substantially on top of the sensor and the roll shell when the coating layer proper is removed. The invention also relates to a method for coating a measuring roll of a fibre-web machine and to a method for replacing a coating of a measuring roll of a fibre-web machine.
摘要:
A method for measuring a nip pressure and/or a pressure profile is provided, wherein a nip-forming roll is fitted with a pressure sensor under a coating layer which is protective and functions as a spring on top of the sensor, and the nip pressure delivers to the bottom surface of the coating a deformation proportional to the nip pressure and the deformation compresses the sensor, which responds to the deformation by generating an electric signal.
摘要:
In a paper or paperboard machine measurements are conducted with at least one measurement means attached to an element in the paper or paperboard machine. The measurement means has two surfaces made of electrically conductive material and has insulating material between them. The change in the capacitance between the surfaces made of conductive material is measured.
摘要:
A movable support apparatus (10), supported on a floor and movable between at least two target stations, for receiving, moving and handing over rolls, winding shafts (1) and/or machine reels (4) intended for the handling of a fiber web. The movable support apparatus (10) has support members (12) for holding up the load being handled (1, 4) at both its support ends (2) and is adapted to be supported on a floor with at least one pressure medium cushion element (40). A handling system includes the movable support apparatus (10). Rolls, winding shafts (1) and/or machine reels (4) may be handled with the movable support apparatus (10). The movable support apparatus may be used as a movable winding stand for the winding of a fiber web (W).
