The present invention relates to a laser-beam protection device for machine tools of the bending press type. This device is characterised in that the means 5 producing the two laser beams comprise a single emitter 4 for the two beams F1, F2, a first semi-transparent mirror 7 arranged at an angle of 45 DEG in the axis of the laser beam coming from the emitter 4, and a second reflecting mirror 8 parallel to the first, located in a same transverse plane, and in that the first and second receiving cells 15, 16 are respectively turned towards the first and second mirrors 7, 8, in order to receive the direct laser beam F1 passing through the first mirror 7 and the deflected laser beam F2 reflected successively on the first and second mirrors 7, 8. <IMAGE> |
