FIELD: clerical aids, in particular, clips for information sheets, bulletins, service and demonstration papers, thin-leaved materials, for instance, films and documents based on them, as well as for captive bookmarks. SUBSTANCE: magnetic clip is made as a blank of thin-leaved cardboard with fold lines applied in parallel with its lateral sides, the first of them forms two pairs contiguously arranged first and second panels; the first group of the fold lines forms the smaller and larger sections of the first panel with the first basic hole made between the extreme fold lines, the middle fold line serves as one one of the axes of symmetry of the first basic hole, whose second axis of symmetry serves as the longitudinal axis of symmetry of the blank of thin-leaved cardboard; the second basic hole is made on the second panel as a reflected image of the first one relative to the first fold line; the second group of fold lines forms a lug in the form of a trapezoid; the means for locking the first and second panels to each other is made in form of strips of elastic polymeric organic compound, including a filler of powder ferromagnetic material, spaced at the blank edges: and a fastening is installed on the second panel; the fastening is made of two-sided adhesive tape, whose upper layer is protected by a film of organopolymeric material. EFFECT: expanded service capacity. |
