Device for the realisation of book or note-book shaped file-holders capable of allowing the insertion and extraction of paper sheets or booklets and/or documents

摘要

The device for the realization of book or note-book shaped file-holders, capable of allowing the insertion and extraction of paper sheets of booklets and/or of documents, comprises a rigid bar (1) attachable to the back of a cover, from whose extremities two extensions (2,2') are laterally projecting in a same direction, having two faces (3,3') opposed to each other. Threads or rods can be inserted from one extension to the other and parallel to said bar, so as to retain the paper sheets or booklets along their entire length and width.
