  • Patent number: 11198199
    Abstract: The invention relates to a method to produce a metal blank with a predetermined contour, with the following steps: continuously moving the metal strip in a transport direction x; concurrently removing material from the surface of a top of a metal strip in at least one predetermined surface section by ablation by means of a first laser that is a component of a first removal device, and then concurrently cutting the metal strip along a cutting path corresponding to the contour of the metal blank by means of at least one second laser that is a component of a cutting device provided downstream of the first removal device; the surface section of an upstream metal blank being produced simultaneously with the cutting of a downstream metal blank.
    Type: Grant

  • Patent number: 9908168
    Abstract: The invention relates to a method for producing a shaped sheet metal part including the following steps, continuous feeding of a sheet metal band unwound from a coil to a jet cutter, concurrent cutting, by means of the jet cutter, of a blank out of the sheet metal band as it moves at a constant speed, the time required to produce the blank defining a cycle, picking up the blank by means of a first transfer device operating in time with the cycle, transferring the blank by means of a first transfer device to a shaping system operating in time with the cycle, and shaping the blank into a shaped sheet metal part by means of the shaping system.

  • Patent number: 9415467
    Abstract: The invention relates to a method for producing a contour cut in a sheet metal web (BB) transported in a direction of transport (T) by means of a conveying apparatus (3). To accelerate the production of the contour cut, it is proposed in accordance with the invention to divide the sheet metal web (BB) into a plurality of overlapping processing strips and to assign successively two laser cutting units (10, 11) to at least two processing strips in the direction of transport (T).
