The invention relates to a production installation (1) for bending sheet metal comprising a bending press (3) with press beams (13, 16), a bending tool (4), a tool manipulation unit (30) for the bending tool (4), and a protective unit (29) with a protective element (32) and an adjusting device (33, 44). The protective element (32) of the protective unit (29) can be moved from a protective position which covers the bending tool (4) into a release position which releases the bending tool (4). The adjusting device (33) comprises at least two brackets (37) and at least two holding arms (38), the protective element (32) being mounted on the brackets (37) in an articulated manner by means of the holding arms (38). The adjusting device (44) can also comprise at least two linear guide arrangements (45) each having a plurality of guide rails (46, 47, 48), by means of which the protective element (32) can be displaced between the two positions.

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.

A stamping press having upper and lower dies to deform a sheet of material. The press has an irregularly shaped opening with greater and lesser height across the width of the press. The press has a guard to prevent inadvertent insertion of extremities between the dies when feeding a sheet for stamping. The guard is also irregular in that it may be skewed to preferentially cover greater parts of the opening and/or may have an irregularly shaped lower edge which can be registered with a like or similar edge of the lower die.
