Safety means for a textile fibre bale opening machine wherein the machine is surrounded by a beam path 7 of a transmitting and receiving device 5, 6 leaving an access opening to loading station 26 which can be entered by a transport vehicle 18, which opening may be closed by further beams 7' (Fig 1b) or 7'' so that moving machine parts in the danger zone can be stopped when the beam path is interrupted. Before and after each entry of the transport vehicle 18 into the region of the loading station a switch-over may be triggered by means of a signal transmitter 15, allowing the transport vehicle to be driven in and out without stopping the bale opening machine. The machine may comprise loading car 10, reserve bale conveyor 25, bale transport conveyor 24 and take-off device 2. The beam generating means may be a light barrier, light curtain or helium-neon laser. <IMAGE> |
