Abstract (en)
[origin: WO2010043430A1] The invention relates to securing a hazardous area in the region surrounding a reel transport (01) on a reel changer, comprising a contactless protective device at the access boundaries of the region which can be deactivated for feeding and/or removing a known object, and comprising an evaluation unit, wherein the protective device is designed as a light curtain (03) comprising a plurality of light beams (04) that run in parallel to each other, wherein the evaluation unit comprises means for detecting the sequence of the interruption of the light beams (04) when feeding and/or removing an object. On the basis of said sequence, a known object that is permitted to access the hazardous area is detected and the protective device is deactivated in this case. Securing a hazardous region further includes a second contactless protection device, which is permanently active.
