  • Patent number: 7449671
    Abstract: In a method and an apparatus for controlling reeling used in connection with the making of paper/board/some equivalent web-like material, a reeler is used in the reeling which has a reeling element (2), a reeling core (T), around which the web (W) is reeled to form a reel (3), as well as elements for loading the reeling core (T) and the reeling element (2) against each other in order to bring about a reeling nip (N) in between the reeling element (2) and the reel (3). The reeling is monitored by a detection apparatus, which automatically detects any events differing from normal reeling.

  • Patent number: 6955107
    Abstract: Support and positioning means (10) and a cutting head (13) supported on them extend in the operating position of the area of the edge part (14?) of a paper web (14). In the cutting head (13), there is a support surface (16) and at least one nozzle (17), which is set in such a way that the edge part (14?) travels between the support surface (16) and the nozzle (15). The equipment includes mechanical cleaning means (20) and/or a cleaning construction (21) for keeping the support surfaces (16) clean. The cleaning means (20) and/or cleaning construction (21) are arranged on the opposite side of the paper web (14) to the nozzle (17).

  • Patent number: 6905090
    Abstract: In the method and device in connection with a reel-up of a paper web there is a rotating reel spool (2) around which a reel (R) has been formed from the paper web (W) passed to the reel-up. In the method web (W) passed to the reel is cut, and the surface layers of the reel are bound by a pressing device (3) which is in contact with the surface of the rotating reel (R) and has a press member (3b) forming a nip with the peripheral surface of the reel and rotating substantially at the same surface speed therewith. In addition to using the press member (3b), the final end, i.e.

  • Publication number: 20040046080
    Abstract: In the method for changing a reel in the reel-up of a paper or paperboard machine or finishing apparatus for paper or paperboard, the cutting of a paper or paperboard web (W) and the guiding of the same on a new reel is conducted by using a tape (5) that is guided into connection with a reeling core (3). Thereafter the tape, as it is positioned on top of the reeling core, at the same time cuts the web (W) and guides the new end of the web following the cutting point around the reeling core. The tape (5) is equipped with an adhesive agent which at the moment of reel change or thereafter is brought to a state that activates the adhesive agent. At least some of the adhesion surfaces of the tape (5) are activated by means of a compression pressure between the reeling core (3) and the reeling cylinder (2).

  • Publication number: 20040011175
    Abstract: Support and positioning means (10) and a cutting head (13) supported on them extend in the operating position of the area of the edge part (14′) of a paper web (14). In the cutting head (13), there is a support surface (16) and at least one nozzle (17), which is set in such a way that the edge part (14′) travels between the support surface (16) and the nozzle (15). The equipment includes mechanical cleaning means (20) and/or a cleaning construction (21) for keeping the support surfaces (16) clean. The cleaning means (20) and/or cleaning construction (21) are arranged on the opposite side of the paper web (14) to the nozzle (17).

  • Patent number: 6581868
    Abstract: The present invention relates to a method and device for the transferring of a web onto a reel spool in the reel-up of a paper web having an empty reel spool (2) that is introduced into a contact with the web (W) running on the reeling cylinder (1) and being still unreeled, to make the transfer possible, and a turn-up blow is used to help the web (W) to break and to be guided on to the empty reel spool (2). The turn-up blow is brought from beneath a horizontal plane passing through the central axis of the reeling cylinder (1) into a location on the mantle of the reeling cylinder that is located after the reel spool (2) in the direction of rotation of the reeling cylinder.

  • Patent number: 6536704
    Abstract: In the method for controlling the structure of a reel, a continuous paper web (W) is reeled around a reel spool (2) to form a reel (R), and one or more variables are measured from the web (W). When a particular, predetermined change occurs in the variable, the lateral oscillation of the web is changed, by means of which the web is guided to different locations in the reel (R) in the axial direction of the reel spool (2). The change can be implemented by starting the oscillation or by changing the oscillation in progress. The change can be implemented on the basis of the changes in the transverse profile of the web (W).

  • Patent number: 6474589
    Abstract: A change device of a reel-up in placed in the reel-up of a paper web in connection with the reel spool (2) forming the core of a new roll and located against the web (W) running onto the old roll (R). The change device comprises a guiding device (3) which is provided with nozzles or the like which are positioned and directed with respect to the reel spool (2) in such a way that they direct air jets (S) to the new end of the web following the cut-off point of the web (W) substantially over the full width of the web, to guide the web around the reel spool (2).

  • Patent number: 6402081
    Abstract: In the method for stopping a machine reel (R) in the final stage of reeling a web (W), the web (W) is cut when the machine reel (R) has become full, the web (W) is possibly guided on a new reeling shaft (2), and the rotation of the machine reel (R) detached from the nip contact with a reeling cylinder (1) is stopped by means of braking forces which are exerted both on the reeling shaft (2) of the full machine reel (R) and on the surface of the machine reel (R). The braking powers which are exerted on the reeling shaft (2) of the machine reel (R) and on the surface of the machine reel (R) and which stop the machine reel (R) are distributed in the ratio (S) of 1:1 . . . 100:1. The ratio can be changed during the deceleration of the machine reel.
