A method of bending and cutting a metal strip (1) into a desired configuration, comprising feeding a metal strip from a strip roll unit, guiding the metal strip from the strip roll unit through a bridge notch forming position and then through a bending nozzle (4a) of a bending unit (4) and then to a cutting position, forming bridge notches (1a) in the metal strip with a jig (21) at the bridge notch forming position, bending the metal strip against the bending nozzle, thereafter cutting the bent metal strip with a cutting unit at the cutting position, the cutting unit and the jig being separate from each other, each of the bridge forming notches extending from an edge of the metal strip and having a configuration, the bridge forming notches being separated from each other in succession by an interval, exchanging the jig for a different jig to change the interval or the configuration of the bridge forming notches upon forming the bridge forming notches with the different jig.
