    15 20 25 30 dimensioned with respect to the customer's requirements. When winding / rewinding at high speed, splicing must sometimes take place and an industrial requirement today is that this must take place without interruption in the process. There are the following very important reasons for this: 1. The primary overall process must not for this trivial reason change speed (changeover to new sleeve / spindle / drum iron / etc.), The changeover must therefore be automatic and very safe - downtime here is also very costly. 2. In the initial production of wider webs, which are later customized to a smaller width, a coarser sleeve / spindle / drum iron / etc. is needed than what the users order on their sleeves. 3. The diameters and lengths of the rollers that the user wishes in his process are usually smaller than what one wishes to handle in any previous process stage. Reduced dimensions mean in an otherwise continuous process more shifts and thus the number of risk factors increases. 4. The roll widths that the users want do not match the material width of the primary process, so the web must be cut lengthwise before winding while split sleeves must be used.
    Prior art methods and devices in this field have been plagued with some more or less serious functional problems for remedying which different kinds of technical solutions have been proposed. However, these have been of such a nature that, on the whole, they have become unstable in terms of function, especially as on process lines of the kind mentioned above there are now requirements such as that they must be able to maintain a continuous web speed so as not to in any way affect the overall process of which the winding is only a small part. In connection with operational disruptions, large amounts of waste are formed, which lead to large unnecessary costs and unnecessary environmental impact.
    As an example, US-A-3,637,155 discloses a winding device which is said to have the ability to automatically change roll when needed to thereby ensure a continuous supply of web-successive rolls fed in turn to its overall process. It is also the case that sometimes for transport technical reasons it is not appropriate to use oversized rollers. Then you are instead forced to splice to maintain a continuous process. The device described in said document comprises at least two pairs of rotatable roller arms on which rollers of the web-shaped material are created. Each pair of roller arms is forcibly rotated along limited angles of rotation under the influence of hydraulic piston assemblies or mechanical devices, in order to rotate the respective roller arm, which is mounted on the associated support frame. However, the device described in said American document is predestined to give rise to operational disturbances during its service life as a result of the complicated mechanical arrangement, which has been used here to achieve splicing operations and in connection therewith also roller changes.
    The invention In short, it is therefore a main object of the present invention to achieve and ensure a fully reliable approach and also a device for effecting automatic roll changes in connection with winding or rewinding of rollers. Such rollers are usually in terms of their dimensions specially adapted to special clients. processes and their requirements for enabling winding or rewinding at high speed with a simultaneous possibility of a high degree of automation when handling spindles / chucks or sleeves / coils.
    According to the invention, the machine is given at least two rolling positions, i.e. positions in which rollers or sleeves are located, each roller sleeve shaft 10 being rotatably guided in each position and all around a common center drum / main shaft while the respective roller sleeve shafts are arranged fully radially steerable in relation to the center drum, whereby the web-shaped material is clamped, between the current sleeve and the center drum.
    This approach achieves, in addition to extremely good opportunities for safe roll changes during operation at full speed, also by rotating the movements that the method describes the respective rollers or if you see it in the overall perspective, and moving with linear movement in connection with the rollers pressed against the center roller radially relative to the latter.
    According to a preferred further developed embodiment of the invention, the web-shaped material is driven and kept stretched by the center drum being driven at a speed corresponding to an overall process speed. This ensures that the peripheral speed of both "leaving" roll and "picking up" roll is always the same, which partly eliminates the risk of slack or overstretching in the web-shaped material, and partly means that the web-shaped material can be changed safely.
    In a further further embodiment of the invention, the roller sleeve shafts in connection with a roller sleeve being completely filled with web-shaped material are rotated to a position which makes it possible that by simultaneously gluing a portion of the web with glue, the web is cut transversely in such a way that the moment thereafter will be adhered to and begin to roll up on a sleeve mounted on the next roller sleeve shaft. The result is a fully synchronized procedure, which ensures that a change of sleeve can take place at the same time as the roll full in connection with the change can be disposed of in a controlled manner and a new sleeve can be inserted instead of the disposed one, to be used in connection with next roll change. Brief Description of the Drawings The invention will be described in more detail below with reference to a preferred embodiment shown in the accompanying drawings, in which: Fig. 1 shows a side view of an arrangement in which the method and the device according to the invention are implemented, Fig. 2 shows a side view corresponding to Fig. 1, but in a rotating position in the method according to the invention, in connection with which one of two roller sleeves is almost filled with rolled-up material, Fig. 3 shows how a full roller sleeve has a horizontal rotational position in the machine while an oppositely located replacement sleeve is Fig. 4 shows how adhesive for application of the roller conveyor to the replacement sleeve is applied after the sleeve has been set in rotation, Fig. 5 shows the event in connection with cutting off the roller conveyor and how this is made to attach to the new sleeve, Fig. 4 6 shows how the new sleeve has subsequently started to roll up the web-shaped material into a new roll, and the full roller sleeve is stopped, Fig. 7 shows how the device rotatable around a center drum is rotated to enable removal of a finished roller and how a lifting table is used to lift it down, Fig. 8 shows how the roller is lowered to floor level while winding continues on it the new sleeve, Fig. 9 symbolically shows how the full roll is transported away while the rotatable device is rotated so that after rotation has taken place past the paper web, a new sleeve is put into standby position for use in the next roll change, and Fig. 10 a position of the rotatable device which actually lies after the position shown in Fig. 2 above.
    DETAILED DESCRIPTION OF THE INVENTION Fig. 1 shows as a side view a rewinding / rewinding machine in which the method and the device according to the invention are implemented. The device, generally denoted by A, generally comprises a stand 1 with a roller arm 2 with drive for rotation / rotation with a low angular speed compared to the web speed (in the order of 0, 25 to 1 rpm, preferably about 0.5 rpm) and a center drum 3 with its own drive for rolling rotation, in the case shown clockwise (with everything from a relatively low speed up to 25 m / s or in extreme cases more). Furthermore, the device has an arrangement with roller holder arms 4, 4a, 4b, of which 4a shows an inner position and 4b shows an outer ditto. Each roller holder arm 4, 4a, 4b, has a roller spindle carriage 5 with drive for linear movement thereof between an inner position 5a and an outer position 5b.
    The roller spindle carriages 5 each have spindles / chucks / tambourine iron 6, of interchangeable variable length and diameter, on which sleeves of different lengths or diameters of the web-shaped material are intended to be arranged, depending on the roll size. A change unit for roll change and sleeve change is generally denoted by 7 and has on the one hand a knife 7a for chopping off the web-shaped material, on the other hand a blowing device 7b for web guide purposes and on the other hand an adhesive application unit 7c. Otherwise, there are guide rollers 8 in the form of input rollers 8a, measuring rollers and other equipment such as web tension control 8b, a web width roller 8d, and guide rollers 8e. The device further comprises a lifting table 9.
    In the following, the approach according to the invention is described with reference to a sequence of drawings from Fig. 2 to Fig. 10 starting from Fig. 2.
    Fig. 2 shows a side view which substantially corresponds to Fig. 1, but on which the roller arms 2 and the roller holder arms 4, under the influence of the drive of the center drum 9, have been rotated about 45 ° compared with the position shown in Fig. 1 to a rotational position. in connection with which a roller sleeve which has almost been filled is placed in a position which is suitable for said replacement. It can be seen from this figure as well as from the previous figure 1 how the web-shaped material is pulled into the winding device, so that via rollers, such as the input roller 8a, the web tension regulating roller 8b, etc. in other words, rollers of various kinds are guided for winding to a roller 11 on a sleeve which is arranged on the spindle 6.
    Fig. 3 shows how a full roller sleeve has reached a horizontal rotational position in which the roller holder arms 4 are horizontal at the same time as an oppositely located replacement sleeve is being put into operation at the opposite left side of the machine. This horizontal position is for skäl your reasons suitable for this operation, partly due to the effect of gravity on the web material in connection with roll change, and partly because the full roll sleeve in this position can easily be brought down to floor level with suitable means (more about this in connection with the description of Fig. 7).
    Fig. 4 shows how glue is applied by means of an application unit 7c intended for the purpose to a part of the web-shaped material, which after cutting it (described in connection with Fig. 5) is intended to fix to a new sleeve on the shaft which takes over the winding after this figure right roll. The roller spindle carriages 5 have their own drive, not least to accelerate each new sleeve / spindle / chuck to a peripheral speed which substantially corresponds to that of the center drum 9 before contact is established between them. It can also be seen from this figure how the roller spindle carriage 5 has started to press a new sleeve against the center drum 3, whereby the speed of the sleeve as mentioned has been synchronized to the speed which it is to have before the sleeve change.
    The web-shaped material is still rolled up on the sleeve on the right in the figure.
    Fig. 5 of the image sequence shows how the web-shaped material which is led into the machine at 10 and further by means of a knife 7a is cut off during a rapid process. It is important to note that this stage of the method according to the invention cannot be initiated until the roller holder arms have been fitted with a new sleeve after their passage of the roller track. Any suitable separating device can be used to achieve such a separation, for example a breaking strip (not shown), which in connection with switching cuts off the web and carries it up on the sleeve / drum drum helically. By means of a blowing device 7b, in the case shown, the front end of the web-shaped material, which is inserted at 10, is forced against the new sleeve on the left in the figure and by adhesion thereby begins a new roll.
    Fig. 6 shows how the winding in the left part of the machine continues and how a small but clearly shown roll has been formed. At the same time, the roller spindle holders which hold the roller spindle, which is now full, have been moved out of the center drum 3 so that the full roller is no longer driven and consequently stopped. In this case, a lifting table 9 also begins to move upwards to meet the right-hand finished roll for removal either at the height shown in Fig. 6 or as shown in Fig. 7.
    This is clear from Fig. 7, which also shows how the roller spindle holders have been rotated a further part of a revolution since the roller has met the lifting table.
    According to Fig. 8, the fully wound roller has been disengaged from the roller spindle holders either by releasing the roller spindle / drum iron from its holders in openable bearing covers (not shown) or from linearly axially drivable roller spindle carriages 5, which are fixed in the machine. The latter option is if you want to automate the roll and sleeve handling is clearly preferable. The lifting table has further been lowered to floor level, after which, as can be seen from Fig. 9, the roller can be removed. The machine is now, as has been said, after it has been turned a further total of about half a turn ready for a new operation with gluing, cutting and roller replacement. This procedure can continue as long as raw materials are available, and Figure 10 shows a state which is de facto attributable to the cyclic procedure before the state shown in Figure 2.
    The invention is not to be considered limited to the preferred embodiment described above, but is to be considered limited by the claims considered in the light of this description.
