  • the reel 4 that is being formed is transferred along a supporting belt loop 3 towards the other end of the wire reeler, in which the second wire guiding roll 2 is located. This situation is shown in Figs 8 and 9 .
  • the web 5 to be reeled is passed to the reeler substantially horizontally.
  • the passing of the web 5 can occur from another direction.
  • the web 5 is passed to the reeler substantially vertically.
  • Figs 10 to 12 show in principle a belt reeler deviating from the preceding embodiment.
  • Such a reeler can be formed for example of a centre-driven reeler of prior art, in which the reeling cylinder has originally moved in the horizontal direction.
  • the reel spool 6 can be stationary, while the reeling cylinder moves as the reeling proceeds.
  • the web 5 is brought to the reeler advantageously in the vertical direction, so that the effect of the web tension P1 on the horizontal movement of the wire guiding roll 1 and on the horizontal nip load measured from its loading members would be as small as possible.
  • the reeler shown in Figs 10 to 12 comprises at least two wire guiding rolls 1, 2.
  • the first wire guiding roll 1 is arranged to move substantially horizontally, and in said embodiment it is the reeling cylinder of the original reeler, or a new wire guiding roll replaced in a corresponding position. If necessary, the wire guiding roll 1 can be locked so that it moves in a fixed position continuously or for some time.
  • the wire guiding roll 2 of the example is arranged movable. Depending on the embodiment, there may also be several rolls, and in view of the use, it is often advisable to use for example four, five or six rolls.
  • One or several moving wire guiding rolls 2 are utilized to control for example some parameters of the supporting member loop, such as the tension P2 and depression P4 of the wire.
  • Fig. 10 shows a situation in which the formation of a reel 4 around a new reel spool 6 is started.
  • the figure also shows the reel 4 that is being formed.
  • the nip 7 of the reel 4 that is being formed is essentially a wire nip.
  • the nip 7 of the reel 4 that is being started is, in turn, substantially a hard nip formed by a roll-wire combination 1, 3.
  • the reel 4 that is being formed is transferred along a supporting belt loop 3 towards the other end of the wire reeler, in which the second wire guiding roll 2 is located. This situation is shown in Figs 11 and 12 .
  • the reel 4 that is being formed may remain in its place from the beginning of the reeling almost until the end of the reel formation, wherein the supporting member loop 3 or at least its first roll 1 is transferred according to the growth of the reel, for example horizontally to the left.
  • the actuators can be actuators used for moving the reeling cylinder of an original prior art reeler, such as horizontal guides and loading cylinders.
  • the nip load of the nip 7 can be determined at least partly from sensors connected to the actuators of the roll 1, such as force sensors and pressure sensors of the hydraulic cylinder.
  • the nip load can be determined in addition to the loading measurement of the roll 1 on the basis of the tension/depression P2, P4 of the wire and/or as a combination of the measurements.
  • the position of the reel spool 6 is arranged movable at least in some stage of the reeling. It is also possible to implement the belt reeler in such a manner that the reel spool 6 that is being formed rotates in its place during the reeling process.
  • Figs 13 and 14 show a reeler solution comprising two stationary reeling stations 11, 12, such as reeling frames, for reel spools 6. Between the reeling stations 11, 12 travels a supporting member loop of the belt reeler 3 that forms a reeling nip 7 and helps in taking the web from one reeling station 11, 12 to another.
  • the supporting member loop 3 of the reeler moves along with the diameter of the reel 4 and both opens and/or closes the reeling nips according to the situation.
  • the first reel 4 is being completed in the second reeling frames 12, and the formation of the new reel is being transferred to the first reeling frames 11.
  • Fig. 14 in turn, the reel has been completed in the first reeling frames 11 and the new reel is reeled in the second station 12.
  • the reeler comprises at least a first wire guiding roll 1 and a second wire guiding roll 2.
  • a first wire guiding roll 1 and a second wire guiding roll 2.
  • Figs 15 and 16 there are for example three rolls that are arranged movable.
  • the first reel 4 is being completed in the second reeling station 12, and the formation of a new reel is being transferred to the first reeling frames 11.
  • Fig. 16 in turn, the reel has been completed in the first reeling frames 11 and the new reel is reeled in the second station 12.
  • the reeling stations (reeling frames) 11, 12 can also be positioned on different heights with respect to each other, as shown in Figs 17 to 20 .
  • the supporting member loop 3 travels via two wire guiding rolls 1, 2 and in Figs 19 and 20 via several rolls. By means of several rolls it is possible to attain easier control of the wire 3.
  • the first reel 4 is being completed in the second reeling station 12, and the formation of a new reel is being transferred to the first reeling frames 11.
  • Figs 18 and 20 in turn, the reel 4 has been completed in the first reeling frames 11 and a new reel is being reeled in the second station 12.
  • Figs 13 to 20 the tail threading in connection with belt reelers takes place advantageously in a similar manner as in current reelers.
  • the empty reel spool 6 can be located in either reeling frame 11, 12.
  • the tip of a wedge is cut and the end of the web 5 is blown around a reel spool 6 located either in the first 11 or in the second reeling frame 12 for example by means of a gooseneck or the like.
  • the tip of the wedge can be cut with a suitable device, such as a waterjet cutting change device.
  • the reeling frame 11, 12 used in the reeling must be changed when the reel 4 has been completed.
  • the tip of the wedge is cut in the change with the waterjet cutting change device.
  • the tip of the wedge is blown on an empty reel spool 6 located in the first reeling frame 11.
  • the tip of the wedge is cut off in the change by means of the waterjet cutting change device.
  • the tip of the wedge is prevented from turning with the web 5 on the surface of the machine reel 4 that is being formed.
  • suction underneath the wire 3 or preventive blowing on top of the wire For this it is possible to use for example suction underneath the wire 3 or preventive blowing on top of the wire.
  • the tip of the wedge continues its travel along the surface of the supporting member loop 3 to the second reeling frame 12.
  • the waterjet cutting change device performs a cutting all the way to the edges, and the web 5 is blown around the reel spool 6 in the second reeling frame.
  • Fig. 21 shows in a top view a belt reeler comprising a first wire guiding roll 1 and a second wire guiding roll 2 through which the wire 3 travels.
  • the wire 3 is shown in broken lines, because the paper web 5 that is wider than the wire has been positioned on top of the wire 3, travelling through the nip 7 between the wire and the reel spool 6.
  • the new reel spool 6 is provided with an adhesive element 13 in the area remaining outside the wire/wires 3.
  • the adhesive element 13 can be formed in various ways, for example by means of a double-sided adhesive tape, by spraying of glue, etc.
  • the change is conducted by cutting a tail in the cross direction at the location of the adhesive element 13 (for example from one edge of the web or from the middle).
  • the tail cut by means of waterjet is deflected towards the reel spool 6 for example by means of a movable member 14 located after the nip 7, or by means of a deflection element fed in said point in the nip 7.
  • the deflection element also makes the cutting of a wedge instead of a tail possible.
  • the tail/wedge adheres on the adhesive element 13 in the reel spool 6, the spreading of the web on the reel spool begins (spreading of cutting devices 15).
  • the wire 3 is not larger in width, that it is advantageously narrower than the web 5 from which the reel 4 is formed.
  • the adhesive element 13 it is easy to arrange the adhesive element 13 at the edge of the reel spool 6 without said adhesive element adhering to the wire 3.
  • a space is arranged in the middle of the reeler at the location of the adhesive element 13, because it is advantageous to have the adhesive element 13 in such a location where the wire is not present.
  • the belt reeler that comprises two or several wires 3, the space between the wires may be formed only for the duration of the change by deviating one or several wi res sideways.
  • the controlled detachment of the tail from the reel spool 6 can be ensured by means of a suitable solution.
  • a suitable solution is a so-called tail-shooter blowing plate that keeps the tail down.
  • the purpose of the solution is to ensure that the floating web 5 does not accidentally adhere to the adhesive element 13 too early. This is possible especially when the distance between the adhesive element 13 from the web 5 before the change is small, for example not larger than the thickness of the wire 3, or smaller. The distance is also affected by the thickness of the adhesive element 13 and the shape of the coating of the reel spool 6, which can be for example narrower at the ends.
  • an adhesive element 13 such as an adhesive tape, pressure-activated adhesive tape or a corresponding structure is installed in the reel spool 6, in an area outside the paper web.
  • the pressure-activated adhesive tape is activated when the nip 7 is closed and the adhesive tape is subjected to pressure.
  • the cutting of a tail from the edge of the web starts at the same time when the nip 7 is closed. Thereafter the narrow tail is deviated in the lateral direction at the location of the adhesive area 13, wherein it adheres to the adhesive agent. The adherence of the tail to the adhesive agent is followed by spreading.
  • the method is suitable especially for slow paperboard machines and for solutions in which the wire 3 is not narrower than the web.
  • the adhesive element 13 does not touch the reeling cylinder 1 when the nip 7 is closed. It is not until the cut tail or the entire web 5 is transferred in the cross-direction at the location of the adhesive element 13 that it touches the adhesive agent and performs a change.
  • the reeler used for the change comprises several different structures and parts.
  • the final configuration depends on the application and the purpose of use of the device.
  • the device can for example contain a tail cutting device.
