Safety arrangement adapted to stop the travel, ie. operational movement of the moving parts (2, 5) of a press brake in the case of the press operator interfering with the travel, ie. operational movement of a tool (6) attached to said moving parts. It comprises emitting means (21) and receiving means (22) of light beams which are provided in a side-by-side arrangement on a side of the press, while, on the opposite side, there are provided reflecting means (26) adapted to convert the light beam (RE.) generated and emitted by said emitting means (21) into a reflected beam (RR) which is parallel thereto and lies closer to the operator than said emitted beam (RE). <IMAGE> |
