Abstract
Hinge for books, or similar, with interchangeable blades, characterized by consisting of a disk-shaped element centered circularly recessed on both sides to create a section by plane diametral normal to these substantially similar to a double T with peripheral rim slightly pumped and in whose flange the head of a recess cut into the edge to be inserted fits the leaf whose recess substantially affects a T-profile slightly smaller than half of the section in double T-disk, so that the lateral parts of said recess, they remain, once the sheet is inserted, in contact with both recessed faces of the disc and with the sheet plane normal to the disc plane.
