  • Patent number: 8833218
    Abstract: A fiber web is reeled by a reeling drum of a reel-up onto a parent roll. When the parent roll has reached the desired diameter size, reeling is changed from the parent roll onto a new parent roll. The web is cut by jet cutting means and the beginning part of the cut web is directed onto a reeling shaft of a new parent roll. The jet cutting path has a main cutting path and at least one edge area cutting path. The length of the main cutting path is at least 60% of the whole cutting path length from one edge of the web (W) to the other edge of the web (W). A turn-up device for a reel-up has one cutting module (15) and at least one nozzle (11) for jet cutting, which is attached movably and turnably to the module (15) by a cutting arm (12).

  • Patent number: 7799171
    Abstract: 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.

  • Patent number: 7757990
    Abstract: 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).

  • Patent number: 7502661
    Abstract: A web is wound in a paper or board machine into machine reels, which are run on a slitter-winder to form customer rolls, whose desired diameter and width are determined according to customer need. A continuous-trimming running mode is used in which a desired amount of web is run into a machine reel and, when needed, splicing is performed on the slitter-winder to produce customer rolls with a desired diameter size. The machine reel diameter is determined based on restrictions set on the location of a splice in the customer roll and the amount of broke produced from the machine reel is optimized. Information about the customer rolls to be slit is obtained from a production control system for calculating/optimizing a machine reel diameter instruction for optimizing the diameter of the next machine reel, and the calculated/optimized machine reel diameter instruction is set in the control system of a reel-up.

  • Publication number: 20080251628
    Abstract: The invention relates to a method and an apparatus in reeling up, in which a paper web or the like (W) is reeled around a center-driven reel spool (5), which is transferred from the primary reeling to the secondary reeling, in which reeling the reel spool (5) is transferred in accordance with the growth of the reel by means of a transfer device (7) at least at some stage of the reeling and the web is brought at said stage from below the reel spool (5) via a reeling nip (N1) formed by the reel spool (5) and a loop (1) of an endless supporting member. According to the invention the web (W) is guided around the reel spool (5) during the reeling via an auxiliary nip (N2) formed by means of the reel spool (5) and the roll (10, 10?).

  • Publication number: 20060175456
    Abstract: Before a reel change a new core (5) is brought to a change station. When the old reel (R) is full, the web is changed to travel to the new core periphery and primary reeling beings. The web forms a reel through a reeling nip (N1) between the loop of an endless supporting member (1) and the core. A change is made to secondary reeling, where a portion of the supporting member (1) brings the web to the reel, to move over to the reel in a nip (N) between said portion and the reel outer periphery. The core (5) is transferred so the nip (N) moves forward. A first guide roll (2) is transferred towards the core periphery so the distance of the nip (N1) located between the core (5) and the loop of the supporting member (1) from the first guide roll (2) changes in the primary reeling.

  • Patent number: 7017855
    Abstract: Successive machine reels are reeled from a paper web (W) so the machine reel (R) that is becoming full is reeled in contact with a movable pressing device (5) at a second reeling nip (N2) in a final stationary reeling station apart from a device (1) forming a first reeling nip (N1). A new, empty reel spool (2) is taken to a transfer device (6) and the change is conducted when the reel spool is located in the transfer device (6). The reel spool (2) with machine reel (R) is transferred after the change by the transfer device (6), while in nip contact with the pressing device (5) away from the first nip contact (N1) to the final reeling station, where the machine reel is reeled so that it becomes full, in nip contact (N2) with the pressing device (5), whereafter the transfer device returns to the change station.

  • Patent number: 6964393
    Abstract: The invention relates to a method in sequential winding stations which are in a production line processing the web at successive stages. In the method the paper web issuing from a paper machine (PK) is reeled in a reel-up (KR1) around a reel spool (T1) to form a reel, the paper web is unwound in an unwind (AR) from the reel to the finishing machine (JK) for paper, and the paper web passed through the finishing machine (JK) for paper is reeled in a reel-up (KR2) around a reel spool (T2) to form a reel. At least the reel spools (T1) used in the area between the reel-up (KR1) of the paper machine (PK) and an unwind thereafter, have different dimensions, advantageously larger diameters, than the reel spools (T2) used later in the production line.

  • Patent number: 6863238
    Abstract: A paper web reeled on a reeling core is affected to form a reel at least by means of the torque of a reeling cylinder and the nip load, wherein in connection with the reel change a new reeling core is brought in nip contact with the reeling cylinder above the reeling cylinder, together with a change device especially a so-called gooseneck. During the reel change an adhesive or the like is applied between the layers of the paper web in connection with the cutting of the paper web by means of a cutting device. The adhesive or the like is applied on the surface of the reel that is being formed by means of a member applying the adhesive.
