A die 12 of a creasing machine comprises a bed plate 13 of hardened steel, having a completely flat upper surface 17. Channels 14 for creasing knives 15 are afforded by rules 19, which are formed of hardened steel, and are secured to the hardened steel plate 13 by means of a layer 20 of a cured adhesive such as epoxy resin, so as to be substantially immovable. To position the rules 19 on the bed plate 13, the rules 19 may be carried on the creasing knives 15 by means of holding strips 21, coated with adhesive, and then pressed down upon the bed plate 13. The strips 21 are subsequently discarded. <IMAGE> |
