    Tearing of the material residues is pressed against them to penetrate them against the mantle surface of the sleeve while tearing the material residue on the sleeve during movement out towards the end of the sleeve and possibly past the end of the sleeve. Several means for lifting and tearing the material residues on the sleeve are moved from their respective positions on the sleeve towards and past each end of the sleeve. A device intended for carrying out the method is characterized according to the present invention in that the means for lifting and tearing the material residues are in the form of a wheel or a hook, which is moved from a position inside the ends of the sleeve to the opposite end during lifting and tearing of the material on the sleeve under pressure against the material on the sleeve. The wheel has a friction surface and is coupled to means for rotating the same towards its axial direction of movement over the sleeve. The wheel is coupled to means for rotating the same with its axial direction of travel preference at a peripheral speed which is different from, if higher than, the speed of the axial movement. The wheel is resiliently mounted to the sleeve and the material remains on it. The hook is provided with a tip in its direction of movement, which is located on the end of a tip carrier, and that the end has an abutment surface facing the sleeve, which is slightly inclined in the upward direction from the direction of movement of the hook, so that the tip is located slightly above the sleeve surface of the sleeve when the hook abuts against it. From the tip of the hook, the surface facing away from the sleeve slopes upwards away from the sleeve for lifting the penetrated material up from the sleeve. The tip of the hook has a rounded spread in the horizontal plane and is pointed in the vertical plane. A wheel with a flexible outer surface is arranged for rotation parallel to the sleeve during rotation thereof and movement axially along the sleeve a number of times. Inside the mantle surface itself, the wheel has a number of open cells or through cavities, which facilitate the shape adaptation of the mantle surface on the wheel to the shape of the mantle surface of the sleeve. The present enables an almost automatic cleaning or restoration of used sleeves for use in the tissue industry to the same condition as new and unused sleeves in the virtually completely without risk of damage to the sensitive sheath material. This means large savings from both an economic and environmental point of view.
    The present invention will be described in more detail below with reference to the accompanying drawings. Fig. 1 shows a perspective view of a sleeve at a part of a device according to an embodiment of the present invention.

    The method of the present invention will become apparent in the following description of various embodiments of an apparatus according to the present invention for carrying out the method or method. A sleeve with material residues in the form of a relatively large number of turns of paper tissue is processed in a sleeve cleaner or roller cutter with a circular knife of a per se known type for removing the majority of the tissue. The innermost layers or turns of tissue are left on the sleeve so that the sensitive jacket surface of the sleeve is not exposed to any damage to the parts of the sleeve cleaner or roller cutter. The parts which can cause damage to the mantle surface of the sleeve are removed or removed from the sleeve to enable further processing of the material residues on the sleeve according to the present invention.
    In Figs. 1-7, a device according to an embodiment of the present invention is illustrated and consists of a wheel 1, which is pressed against a sleeve 2 with tissue 3 in the direction of the arrow 4. The wheel 1 has a friction surface and is advantageously manufactured of rubber or a rubber-like material, such as polyurethane. The wheel l may have a rounded narrow mantle surface. The wheel 1 is moved in the direction of the arrow 5 in Fig. 2 along the sleeve 2 and rotated according to the arrow 6 in the direction of the direction of movement according to the arrow 5 to the end of the sleeve 2. Before the wheel 1 is moved in the opposite direction to the opposite end of the sleeve 2 its direction of rotation so that the wheel 1 rotates against the axial direction of movement. This alternating movement of the wheel 1 is continued until the tissue is inflated as indicated in Figs. 3, 6 and 7 and until the mantle surface of the sleeve 2 is visible. It is important that the wheel 1 is resiliently mounted so that the jacket surface of the sleeve 2 is not damaged.
    It is also possible to rotate the wheel 1 with the axial direction of travel provided that its peripheral speed is different from (preferably higher than) the axial speed of movement. An advantage of this is that it is possible to avoid the appearance of a so-called “rolled edge” on the tissue, which is extremely difficult to crack but must be cut with a great risk of damage to the sleeve surface 2. After lifting and cracking or tearing the tissue according to the previous paragraph, either the sleeve 2 can be rotated, a doctor blade is applied in the opening and the sleeve is rotated or air is blown into the created opening to remove the tissue. These removal methods can of course also be combined with each other to remove the residual tissue from the sleeve 2.
    Figs. 8 to 15 illustrate another embodiment of a device according to the present invention in which the wheel 1 is replaced by a hook 7, which in a position slightly inside the end of the sleeve 2 is pressed in the direction of the arrow 8 against the material residues or tissue 3 on the sleeve 2 and is moved axially along the sleeve 2 in the direction of the arrow 5 to the opposite end of the sleeve 2. In this movement the hook 7 or its tip 8 will seek down towards the mantle surface of the sleeve 2 and parallel thereto while tearing the tissue 3, until the end on the sleeve 2 has been passed. Either the hook 7 can be turned or another similar hook can be arranged for movement in the opposite direction after engagement with the tissue some distance inside the opposite end of the sleeve 2. The hook 7 or the hooks are moved back and forth on the sleeve 2 until the surface 9 of the tip 8 comes into contact against the mantle surface of the sleeve 2 and is moved on the same without causing any damage. For this purpose, the surface 9 can be directed slightly upwards towards the tip itself 8. Changes in the direction of the surface 9 to and from parallelism with the mantle surface on the sleeve can be effected by pivoting the hook 7 and its tip 8 upwards or downwards.
    After the lifting and cracking or tearing of the tissue according to the previous paragraph, either the sleeve 2 can be rotated, a scraper is applied in the opening and the sleeve is rotated or air is blown down into the created opening to remove the tissue. These removal methods can of course also be combined with each other to remove the residual tissue from the sleeve 2.
    In combination with a sleeve cleaner or roller cutter with a circular fixed or rotating knife, a wheel 1 or a hook 7 can be arranged on one or both sides of the knife in the sleeve cleaner or roller cutter and can be lifted or lowered with the knife and can also be movable. independent of the knife. The hook 7 is suitably mounted pivotable about its opposite end 8 relative to the tip 8 and may be coupled to a cylinder or the like for pivoting towards the mantle surface of the sleeve 2 with the desired force.
    In experiments, it has been found that the dead weight of the hook 7 is sufficient for it to penetrate into and down the tissue 3.
    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.
