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.

A method for cleaning a separator core in accordance with an embodiment of the present invention is a method for cleaning a separator core having an outer peripheral surface around which a separator is to be wound, the method including: an end face cleaning step of removing a foreign object adhered to an end face of the separator core.

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.

The cable core separation system includes a gripper moving device and a gripper. The gripper moving device includes a mounting plate, a slide rail, a first slider, a second slider, a connecting member, and a driving mechanism. The slide rail is fixed on the mounting plate and has a first slide rail and a second slide rail vertically connected to a front end of the first slide rail. The first slider is installed on the slide rail and moves along the slide rail. The second slider is installed on the slide rail in front of the first slider and moves along the slide rail. The connecting member has two ends each rotatably connected to one of the first slider and the second slider. The driving mechanism is installed on the mounting plate and connected to the first slider. The driving mechanism drives the first slider to move along the first slide rail. The gripper installed on the second slider grips and separates a core wire of a cable. The second slider moves between the first slide rail and the second slide rail under a drive of the first slider such that the gripper is switched between a first state parallel to an axial direction of the cable and a second state parallel to a radial direction of the cable.
