• Fig. 1 shows the reel-up according to the invention in a side view. It comprises a stationary reeling cylinder 1 that is journalled rotatable, via which reeling cylinder the paper web coming from a paper machine or a finishing apparatus for paper is reeled on a machine reel R.
• the full machine reel R is outlined in the drawing.
• the reel-up type is a continuous reel-up in which the paper web is changed to travel on a new reel at the running speed.
• the reel ⁇ up can also be a re- reeler.
• the web is reeled to form a machine reel around a reel spool 2 equipped with a centre drive of its own.
• the drawing shows a reel spool at the initial stage of the. reeling (paper web not shown).
• the web enters the reel via a reeling nip N located between the reeling -cylinder 1 and the reel, the linear load prevailing in said reeling nip being controlled by means of force devices according to a principle known as such.
• Fig. 1 shows a sledge located on one side of the reel-up, and a corresponding sledge as well as other structures located in conjunction therewith also on the opposite side.
• the upper surface of the sledge 3 forms an approximately horizontal supporting surface 3a, the bearing housing located at the end of the reel spool 2 resting on top of the surface.
• This sledge 3 is arranged movable under the control of at least one linear guide 9 in the growth direction of the reel, i.e. in the radial direction of the reel.
• the linear guide 9 is positioned in a supporting frame 10 above the floor level.
• the sledge 3 replaces the stationary reeling rail on top of which the reel spool has rolled forward according to prior art during the nip-closed reeling.
• the supporting surface 3a is located at the same height than the stationary reeling rail K located at the end of its track of movement and belonging to the supporting frame 10.
• the upper surface of the reeling rail K functions as an extension to the supporting surface 3a, and the end of the reel spool 2 can roll from the supporting surface 3a to the upper surface of the reeling rail K.
• Fig. 1 also shows a reeling carriage 4, which is moved in the growth direction of the reel with a force device 5, and which also determines the linear load in the reeling nip N.
• the force device is typically a pressure medium operated actuator, such as a hydraulic cylinder.
• the carriage 4 also contains a locking jaw 6 that is journalled pivotable in the vertical plane, said locking jaw entering on the opposite side of the nip N in contact with the peripheral surface of the bearing housing in the end of the reel spool, as well as a corresponding actuator 7 that turns the locking jaw.
• the sledge 3 that moves under the guidance of the linear guide as well as the carriage 4 that is moved by means of the force device 5 are connected together in such a manner that they can be moved as a single entity.
• By moving the carriage 4 by means of the force device 5 it is at the same time possible to move the sledge 3.
• a separate actuator is not needed for the movement of the sledge 3.
• the same advantages are attained in the precision of the control of the reeling parameters as presented earlier in the publication WO 99/65806.
• the track that supports the sledge 3 during its movement is located in the supporting frame 10, which, in turn, is supported by the floor level or a corresponding horizontal supporting base.
• the track of the sledge is located between the supporting base (floor) and the supporting surface 3a in the height direction, and advantageously closer to the supporting surface 3a than to the supporting base of the supporting frame, in other words, the sledge 3 is relatively low and easy to move.
• Figs 2a to 2d show the different stages of the reeling process implemented by means of the invention.
• the drawings show the reel- up schematically from one side and the corresponding parts on the other side of the reel-up are at the same stage, whereby the movements of the moving parts located on different sides occur in a synchronized manner.
• Fig. 2a shows the reeling carriage 4 and the sledge 3 in the final station in which the sledge 3 has been brought against a shoulder located between the horizontal supporting surface of the supporting frame bearing the linear guide 9 and the upper surface of the reeling rail K.
• This final station is attained when the machine reel R has reached its final diameter, and it has been driven off the reeling cylinder 1 by means of the carriages 4, wherein the reeling nip N opens.
• a separate press device 11 that can be a rotating roll or a brush device, has been transferred against the peripheral surface of the reel to prevent access of air to the reel between the topmost paper layers still entering the reel.
• Fig. 2a also shows a new, empty reel spool 2 brought to the change station.
• the new reel spool is transferred and rotated by means of a primary reeling device 8 that is capable of transferring the reel spool in the direction of the peripheral surface of the reeling cylinder 1.

• the reel spool is supported by the primary reeling device 8 in a position in which its bearing housings are located above the level defined by the track of movement of the supporting surface 3a.
• Fig. 2b the change has been conducted and the full machine reel R has been transferred from the support of the supporting surfaces 3a to the stationary reeling rails K to a discharge station, from which it can be transferred off the reel-up for example by means of a crane.
• the reeling carriage 4 along with the sledge 3 are transferred towards the reeling cylinder 1 to receive the new reel spool 2, around which the formation of a new machine reel R has begun.
• the sledge 3 is driven to a suitable position in relation to the new reel spool 2 by means of the carriage 4.
• FIG. 2c shows a situation in which the new reel spool 2 has been lowered down by means of the primary reeling device 8 in nip contact with the reeling cylinder 1 to such an extent that the bearing housing in the end of the reel spool 2 is brought on top of the supporting surface 3a of the sledge 3.
• the locking jaw of the carriage 4 is turned into contact with the bearing housing, and at this stage the torque is also changed from the drive of the primary reeling device 8, i.e. from the primary drive, to the drive by means of which the reel spool 2 and the machine reel R are rotated until the end of the reeling, i.e. to the secondary drive.
• Fig. 2d shows a situation in which the reel has grown into its full size and the reeling carriage 4 and the sledge 3 have been transferred further away from the reeling cylinder 1 according to the change of position of the reel spool 2. Thereafter the above-described press device is driven into contact with the reel, and the reel can be transferred by means of carriages 4 to the position shown in Fig. 2a.
• the change can also be conducted in such a manner that during the change the full reel is in nip contact with the reeling cylinder, a new empty reel spool 2 is transferred to the change station by means of the primary reeling device, the paper web W is changed by means of some change method to travel around a new reel spool 2, and the full reel is thereafter released from the nip contact and transferred onto the support of the stationary reeling rails K by means of the carriages 4, and finally, the carriages 4 are driven to the reeling cylinder 1 to a receiving station so that the reel spool 2 around which the formation of a new reel has begun, can be lowered on the support of the supporting surfaces 3a of the carriages 3.
• the full reel R is in the position shown by Fig. 2d.
• Fig. 3 shows the carriage 4 and the sledge 3 when seen in the direction of the reeling rails and the guide.
