A wrapping or roll-up device including a base, one or more connectors, an arm, and a handle. In embodiments, one or more connectors are connected to the base and are configured to connect the device to a wall or support structure, and/or the arm includes an aperture. In embodiments, a handle includes an extended portion and a grip portion, and at least a portion of the extended portion is configured to extend through the aperture. Further, with embodiments, the extended portion includes a slot disposed about an end of the extended portion. Embodiments may include a tensioner. Methods for wrapping or rolling up an article such as a wrap are also disclosed.

A method for producing a tape-wound toroidal core includes: providing a soft-magnetic tape on two tape reels, unwinding the tape and winding the tape onto two winding mandrels to form a multilayer first tape roll, wherein, after in each case several layers, a separating plate is inserted into the first tape rolls that have formed, reducing the distance between the winding mandrels until the first tape rolls touch each other, unwinding the tape and winding up the tape to form a multilayer second tape roll, which wraps around the first tape rolls, by rotating the winding mandrels about a common second rotation axis, severing the tape rolls in steps to form a plurality of tape sections, picking up at least one reel and placing the reel onto the tape sections, reshaping free ends of the tape sections and connecting the ends of the tape sections to form a closed ring.
