<p>The anchoring mechanism is for a file accommodating perforated sheets, and comprises a baseplate with anchoring pins riveted into holes in it at a portion higher than its edge. The baseplate (1) is indented downwards where these holes for the pins (2) are formed, so as to form a recess, in which a filler piece, integral with each pin and of larger diameter, is inserted. The recess and filler piece can both be conical. The design allows the entire height of the pin to be used to accommodate sheets, so that more can be contained in a single file.</p> |
