Abstract
The invention relates to a method for cutting a sheet metal blank from a sheet metal strip (1) continuously conveyed in a transport direction (T), by means of at least one laser cutting device (3), having the following steps:
- providing a laser cutting device (3) with at least one laser cutting head (5) which has a cutting nozzle (7) and which can be moved along a cutting path (S1, S2, S1′, S2′) specified so as to correspond to the geometry of the sheet metal blank by means of a controller (6), incrementally measuring the distance between the cutting nozzle (7) and the surface of the sheet metal strip (1) at at least one radially outer position (P1, P2) relative to the cutting nozzle (7) by means of a first distance measuring device (8),controlling the movement of the laser cutting head such that the first distance measuring device (8, 9) constantly remains overlapping the sheet metal strip (1), into a second position, in which the cutting nozzle is overlapping the sheet metal strip (1), wherein the height of the cutting nozzle (7) relative to the surface of the sheet metal strip (1) is regulated using the first distance values supplied by the first distance measuring device (8, 9) when the cutting nozzle (7) is moved from the first position in the direction of the second position.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
