    15 20 25 30 35 internally and the end of the sleeve is machined externally. One or more adhesive strands are applied to at least one of the machined surfaces and the splice sleeve and the sleeve are compressed and kept compressed for a predetermined period of time. Excess glue is removed on the inside and / or outside. An empty sleeve is cut into suitably long splice sleeves and one end of a selected splice sleeve is machined into a suitable joint surface. An empty sleeve with a splice sleeve at one end was turned so that the end without a splice sleeve is processed for joining with a splice sleeve. Empty sleeves with splice sleeves at both ends are alternated so that different ends of the sleeve are fitted with splice sleeves from time to time.
    The length of the splice sleeve varies.
    The present enables a particularly efficient utilization of the sleeves in the tissue industry. This means large savings from both an economic and environmental point of view.
    A major advantage of the method according to the present invention lies in the fact that the central part of the sleeves is not affected, since the joint will always be positioned to the ends of the sleeves. This is of particular importance, since the loading of the sleeves is oriented to the central part of the sleeves and this central part is not affected by the method according to the present invention. A further advantage of the method according to the present invention is that the new joint always ends up at substantially the same distance from the end edge, which makes it easy to apply the joint adhesive to one or both joint surfaces and to remove excess glue on both the inside and the outside. It is of particular importance that excess glue is removed on the inside, as the sleeves often sit on an expanded shaft during winding.
    The present invention will be described in more detail below with reference to the accompanying drawings. Fig. 1 shows four views of sleeves during different steps while carrying out an embodiment of the method according to the present invention. Fig. 2 shows three views of sleeves during different steps while carrying out an embodiment of the method according to the present invention. Fig. 3 shows three views of sleeves during different steps while carrying out another embodiment of the method according to the present invention. Fig. 4 shows three views of sleeves during different steps while carrying out yet another embodiment of the method according to the present invention. Fig. 5 shows a layout of a device for carrying out the method according to the present invention.
    The method according to the present invention will now be described in connection with the preparation or gluing of large sleeves, eg 2540 mm long and with a diameter of 305 mm, on which non-self-supporting materials, eg tissue are wound, so that reuse of identical sleeve lengths made possible. A used sleeve is cleaned of residual material and adhesive residues. Such an output sleeve 1 is shown in Fig. 1 and at both ends of the output sleeve 1 a sleeve piece 2 and 3 is cut off. The length of the sleeve pieces 2,3 can be 50 - 100 mm.
    A splice sleeve 4 is machined at one end to form a joint surface 5, which is internal and conical. One end of the cut-out outlet sleeve 1 is machined to form a joint surface 6, which is external and conical. The conicity of the joint surfaces 5 and 6 fits together. A suitable adhesive is applied to one or both joint surfaces 5 and 6. The adhesive may be a cold adhesive or a combination of a cold adhesive and a hot melt adhesive. After the glue is applied, the outlet sleeve 1 is joined to the joint sleeve 4 for compressing the joint surfaces 5 and 6 with each other. Compression takes place over a predetermined period of time, for example from one to a number of minutes (20 minutes (eg 30 seconds) minutes) depending on the type of glue.
    After compression, excess glue is removed on the outside and inside. It is of particular importance that excess adhesive be removed on the inside, since the sleeve usually sits on an expanded shaft during the winding of the material thereon.
    If necessary, the length of the output sleeve 1 provided with the splice sleeve 4 is adjusted to the correct and desired length. If the splice sleeve 4 has a length of the total length of the sleeve pieces 2 and 3 plus the horizontal joint surface length, it may be possible to avoid the adjustment creation of the new reusable sleeve 1 with the glued splice sleeve 4. After determining whether the sleeve 1 with the splice sleeve 4 has the correct longitudinal sleeve 4 it can be reinserted in the winding machine.
    Fig. 2 shows a combination 7 of an output sleeve with a glued joint sleeve. From the combination 7 a sleeve piece 8 and a sleeve piece 9 are cut off. The end of the combination 7, which lacks a joint sleeve piece, is machined to form a joint surface 6, which as in the previous embodiment is external and conical for co-operation with a joint sleeve 4 with a corresponding joint surface 5. After applying glue, the combination 7 is combined with the joint sleeve 4 for compressing the joint surfaces 5 and 6 with each other for a predetermined period of time. After determining whether the combination 7 with a new splice sleeve 4 has the correct length, it can be reinserted in the winding machine.
    The embodiment shown in Fig. 3 is in principle the same as the embodiment described in connection with Fig. 2, except that the combination 7 is turned or rotated half a turn so that the end provided with the splice sleeve 4 points in the opposite direction.
    Fig. 4 shows an embodiment, according to which sleeve pieces 8 and 9 are cut off from a combination 7 and the joint sleeve end of the combination 7 is machined to form a joint surface 6 for joining a joint surface 5 on a joint sleeve 4. After gluing on 15 The joint surfaces 5 and 6 the parts are compressed for a predetermined period of time. Although the embodiment of Fig. 4 is fully usable, it is preferred to place the splice sleeve 4 every other time on every other end of the sleeve combination. This would mean that in the embodiment according to Fig. 4 the splice sleeve 4 would be placed on the right end of the combination 7 shown in Fig. 4. This gives optimal strength in that the central part of the sleeve combination will always be free of splice, ie unscrewed which is advantageous, since the central part of the sleeve is exposed to the greatest stresses. After placing a splice sleeve 4 on both ends of a sleeve 1, it is not critical with the choice of end of the sleeve 1 for the placement of a splice sleeve 4, although a regularity is preferred.
    Fig. 5 shows a layout of a machine for carrying out the method according to the present invention. A magazine 1 with sleeves, from which tissue residues and adhesive residues have been removed and which can thus be said to be empty, is connected to an feeder 2 for feeding one sleeve at a time to a sleeve 3, in which sleeve pieces 2,3,8 and 9 can be cut from a sleeve and in which an entire sleeve can be cut up to a number of splice sleeves if necessary. The splice sleeves are moved by means of the dispenser 4 and placed on a conveyor 6 for splice sleeves by means of a transfer robot 5. This robot 5 also transfers cut sleeve pieces 2,3,8 and 9 to a conveyor 8, which can lead to a scrap container. A transfer robot 7 moves splice sleeves from the conveyor 6 to a processing and gluing unit 11 for forming a joint surface. An end-cut sleeve is moved with the dispenser 4 to a table 9 with the possibility of zero line adjustment and further to a feed unit 10, with which the sleeve is fed into the processing and gluing unit 11 to form a joint surface. After glue application, the joint surfaces are compressed and kept compressed for a predetermined period of time. The sleeve provided with a splice sleeve is placed on the table 12 for further movement to the grinding unit 13 and a sleeve 14 for removing excess glue and length correction. The machine is operated from a control panel 15. A suction unit 17 is arranged for dust extraction. Furthermore, the machine is surrounded by a protective fence 18 and the machine also includes a number of electrical cabinets 16.
    Many modifications of the above-described embodiments of the present invention are, of course, possible within the scope of the inventive concept defined in the appended claims.
