Abstract (en)
Jigsaw puzzles are manufactured using a punch-and-die assembly by which interlocking pieces are cut out in a single cutting operation, resulting in the production of jigsaw puzzles having sharp straight-sided edges. The punches (20) and ejector pieces (24) of the tools (10,12) constituting such assembly are preferably manufactured by a wire erosion technique using a wire of small diameter, e.g. 0.1mm (0.004"). The assembly may be an independent unit for use in combination with a conventional hydraulic beam press, or may be a unit designed for use in a purpose-built press. <IMAGE>
