Abstract
A cylindrical winding tool 3 has three elongated members 5 obtained by splitting a cylindrical member in its axial direction into multiple pieces. The elongated members are interconnected in a hinged state in a circumferential direction by the magnet sheet. When the elongated members 5 are to be used, the elongated members 5 are placed in a spread state and arranged on the magnetically-attached object 4. When the elongated members 5 are not used, the elongated members 5 are gathered together in the circumferential direction, abutment sections 5b of the end faces of the adjacent elongated members are brought into abutment on each other and thus the cylindrical winding tool 3 having a required diameter can be formed.
Claims9
A magnet sheet winding device comprising:
- a magnet sheet having flexibility;
- and
- a cylindrical winding tool having a required diameter, attached to one side of the magnet sheet, and configured to rewind the magnet sheet, wherein the magnet sheet in an in-use state is unrolled from the cylindrical winding tool and magnetically attached to a magnetically-attached object and the magnet sheet in an unused state is rewound on the cylindrical winding tool, the magnet sheet winding device being characterized in that
- the cylindrical winding tool comprises a plurality of elongated members obtained by splitting a cylindrical member in an axial direction of the cylindrical member,
- the elongated members are connected in a hinged state to each other in a circumferential direction,
- the elongated members are spread in the in-use state such that the elongated members are allowed to be arranged on the magnet sheet unrolled on the magnetically-attached object so as to be flush with the magnet sheet, and
- the elongated members in the unused state are gathered together in the circumferential direction, and abutment sections of end faces of the adjacent elongated members are brought into abutment on each other so as to form the cylindrical winding tool having the required diameter.
