<p>1,067,624. Cutting-out presses. COMPO SHOE MACHINERY CORPORATION. July 15, 1965 [July 17, 1964], No. 30054/65. Heading B4B. [Also in Division F1] In a die-cutting machine as described in Specification 1,067,623, the die is supported at a predetermined distance above a hardened but deflectable metal platen 15 for movement perpendicular thereto into engagement with work resting on the platen, and the platen is supported so that it will yield under the application of cutting pressure, the cutting stroke for the die being made greater than the predetermined distance between the die and platen so as to displace the portion of the platen with which the die has contact downwardly into parallelism with the entire cutting edge of the die. The platen is comprised of a hardened and ground steel harder than the die, having a thickness of the order of # to <SP>5</SP>/ 16 inch. Preferably, the platen is supported on a rigid bed 14 through the intermediary of a pad 34 of rubber, or its equivalent, having a thickness of the order of # to # inch and a durometer hardness of the order of 40 to 80. The die is moved into engagement with the platen by means of a reversible fluid-pressure motor of adjustable stroke.</p> |
