A protection apparatus at a weaving machine for the protection of persons in danger regions, comprises first light curtain arrangement associated with a more comprehensive region and a second light curtain arrangement associated with a central region, the actual region, with the former being brought during a normal operation of weaving machine into an active state which ensures the protection. A protection apparatus at a weaving machine for the protection of persons in danger regions that extend about a beat-up edge along a weaving width and beyond the latter, comprises first light curtain arrangement (1), which emit and register light beams (12) arranged in the apparatus about the danger regions and with it being possible to produce, by the light beams in the first light curtain arrangement, signals which arise as a result of encroachment into the danger regions and through which an operating stop of the weaving machine can be triggered. The first light curtain arrangement is associated with a more comprehensive region and a second light curtain arrangement is associated with a central region, the actual region, with the former being brought during a normal operation of weaving machine into an active state which ensures the protection and with the activation of the second light curtain arrangement being provided for use during activities which are occasionally to be carried out at the weaving machine within the more comprehensive region. An Independent claim is also included for a method for an accident protection comprising controlling the first light curtain arrangement in such a manner that during a standstill of the machine, in a starting-up operation or during a creep speed operation only the second light curtain arrangement is brought into the active state; and after starting up of the weaving machine, i.e. after a start of the normal operation, activating the first light curtain arrangement, with it being possible for the second light curtain arrangement to be left in the active state or to be deactivated. |
