ABSTRACT:
In order to optimize a process for the machining of sheet-metal parts in a bending unit of a bending center, in which the sheet-metal parts are transported one after the other from a feed area to the bending unit for the purpose of bending and are thereby taken over by a first manipulator of a manipulator arrangement in a takeover position and then placed against a bending edge for carrying out at least one bending operation, it is suggested that after the last bending operation each finished sheet-metal part be moved away from a bending end position, that during the bending operation of each one of the sheet-metal parts the next respective sheet-metal part be supplied, proceeding from the feed area, to a takeover position arranged so as to be non-overlapping in relation to the bending end position and in this be positioned for gripping by the first manipulator and that the first manipulator begin to take over the next sheet-metal part in the takeover position during the period of time, during which the finished sheet-metal part is leaving the bending end position.
