Abstract: In a method for removing a wrapping, such as plastic film, from a roll of material an apparatus is used, which has a roll supporting unit, and a cutting means. The roll supporting unit is configured to rotate the roll supported thereon, and the cutting means is movable into cutting abutment against the envelope surface of the supported roll for removal of the wrapping during rotation of the roll.

Abstract: A core end piece collector for handling cut off end pieces during processing of tubular cores with a hollow centre portion includes a carrying member. At least a portion of the carrying member is configured to be arranged inside of a core during cutting of the core. The collector further includes a catcher being arranged on the carrying member, said catcher protruding from the carrying member at an angle in relation to the longitudinal direction of said carrying member such that the catcher is insertable into a cut in the core. The core end piece collector further comprises means for moving at least the carrying member in relation to the core.

Abstract: A method (and device) of removing material residues, from cores to make possible reuse of them in the same manner as new and unused cores a number of times wherein cores with material residues in the form of a number of material turns are processed using a mechanism for lifting and tearing the material residues for subsequent simple removal thereof, the mechanism for lifting and tearing of the material residues is displaced along the core and the mechanism for lifting and tearing of the material residues is displaced from a position in on the core out towards and past the ends of the core.

Abstract: The present invention concerns a method for removal of material residues, particularly tissue or similar porous, non-self-supporting materials, from a material-carrying core, which often has relatively large dimensions, e.g. a diameter of approx. 300 mm and a length of approx. 2540 mm, and thereby allow re-use of the core in the same way as new and unused cores a number of times for winding non-self-supporting or porous material, particularly tissue, wherein a cut section is made in the envelope surface of the roll having the material-carrying core from one end or end portion of the roll to the other end or end portion of the roll by means of a driven rotary knife, which is connected to a motor for rotation of the same.

Abstract: In a method for recycling residual rolls having a material-carrying core of tubular shape with a hollow centre portion, the core is adapted to carry web material, such as tissue, that is rolled or wound onto the material-carrying core for facilitating handling and transportation of the web material. A device for carrying out this method has means for removing residual material from the core, means for collecting the residual material, and means for inserting residual material into the hollow centre portion of the core. Thereby, the core can be handled and transported with the residual material kept inside the core.

Abstract: A method and device of stripping of wrapping material including a tool having a first tool portion, a second tool portion, and a third tool portion comprising ends and a casing on substantially cylindrical rolls of paper and the like, in which the end of the wrapping material is opened by engagement by means of a first tool portion from some position on the end surface for processing the end wrapping material by cutting, slicing, and/or sawing of the end wrapping material in a direction out towards the periphery of the end where the end connects to the casing, the end being separated from the casing by means of the first tool portion or a second tool portion by cutting, slicing, sawing during rotation of the roll and/or displacement of the first tool portion or the second tool portion around the periphery of the end.

Abstract: A device for processing cores with a view to restoring same for reuse as good as new and unused cores a number of times for handling and carrying of different types of material webs, includes a number of processing units being arranged to act on the core for removal of material residues and possible other residues in the form of adhesive. The processing surface of the processing units is adapted and/or arranged to adapt itself to the surface of the core on at least the processing thereof under the exercise of a compression pressure between the core and the processing units.

Abstract: The invention relates to a folding door with a door leaf (4) which is movable between a closed position and an open, folded position, in which the door leaf (4) is folded about folding lines between opposite side edges (5) of the door leaf. A plurality of guide members (110-118) are connected to the side edges (5) in a spaced-apart relationship along the same, and two side frames (1) are extended adjacent to a respective side edge (5). Each side frame (1) defines at least a first and a second guide groove (68, 69), which are juxtaposed transversely of the side frame. The guide members comprise, at each side frame (1), a first set of guide members running in the first guide groove (68) only, as well as a second set of guide members running in the second guide groove only (69).
