摘要： The invention relates to a bending machine, in particular a press brake, having an upper beam and a lower beam. The upper beam is movable in a working direction of the bending machine in order to form a workpiece by bending along a bending line, which extends in a width direction of the bending machine. The bending machine includes a safety system having a first functional element and a further functional element for monitoring a safety area between both functional elements and between the upper beam and the lower beam. The safety system is arranged to follow the movement of the upper beam in the working direction. The first functional element and the further functional element are mechanically connected to one another via a flexible tractive force transmission means and an adjustment device for changing the position of the functional elements. The adjustment device includes a coupling section.
