ABSTRACT:
An apparatus at a weaving machine serves for the protection of persons in danger regions which extend about a beat-up edge along a weaving width and beyond the latter. In this apparatus, monitoring means which emit and register light beams are arranged about the danger regions. Signals which arise as a result of an encroachment into the danger regions and through which an operating stop of the weaving machine can be triggered can be produced in the monitoring means by means of the light beams. First monitoring means are associated with a more comprehensive region and second monitoring means are associated with a central region, the actual danger region. During a normal operation of the weaving machine the first monitoring means are in an active state which ensures the protection. An activation of the second monitoring means is provided for use during activities which are occasionally to be carried out at the weaving machine within the more comprehensive region.
