Abstract (en)
Rotary die cutting apparatus comprising a driven rotary cylinder (10) on which is circumferentially mounted a removable forme (11) having knives (14) projecting radially therefrom. The forme (11) is magnetically retained on the surface of said cylinder (10) by a plurality of longitudinally extending steel bars (15, 16, 17) which locate within grooves (19) in the surface of the cylinder (10), each groove (19) coinciding with a plurality of longitudinally spaced magnets (20) which retain the forme (11) during rotation of the cylinder (10). The magnets (20) may be electro-magnets such that the forme (11) is removed by switching off the current to said magnets, or alternatively permanent magnets such that a tool will be required to release the steel bars from the grooves (19). <IMAGE>
