Abstract: A press machine includes a frame, a punch die supported by the frame, a guide track supported by the frame, and a heater coupled to the guide track. The punch die is driven through a punch stroke to punch a strip advanced through the press machine at a punch zone. The guide track has a guide rail forming a guide channel configured to receive the strip. The guide channel is aligned with the punch zone to guide the strip to the punch zone. The heater heats the guide rail to an elevated operating temperature. The guide rail is used for conduction heating of the strip as the strip passes through the guide track.

Abstract: A method for producing a card element. In a step, a first material layer having a predefined card body and at least one position marking is provided. In a step, a second material layer having at least one recess extending through the second material layer is provided. In a step, the second material layer is applied onto the first material layer in such a way that the position marking in the first material layer can be optically detected through the recess extending through the second material layer. In a step, a separating device is aligned on the basis of an optically detected location of the position marking. In a step, the predefined card body is separated from the first material layer by means of the separating device so as to produce the card element.

Abstract: The present disclosure concerns a process for the blanking of metal parts (1) from a—layered basic material (51) composed of a number of mutually stacked individual layers (50) placed and clamped between a blanking die (80) and a blank holder (70) of a blanking device (100), wherein a blanking punch (31; 32) of the blanking device (100) is moved relative to the blanking die (80) to cut and separate the metal parts (1) from the basic material (51). According to the present disclosure, such multi-layer blanking process is carried out in two successive stages (I, II), whereof a first stage (I) entails the punching of holes (3) by a first blanking punch (31) without applying a counter punch and whereof a second stage (II) entails the blanking of the metal parts (1) by a second blanking punch (32) while being supported by a counter punch (40).
