摘要
The invention relates to a device for detecting an obstacle and limiting the force from the primary edge or sill nosing (10) of a flexible apron or curtain (5) in a goods-handling door (1) when the latter comes into contact with an obstacle (14) as it is being closed. The inventive device comprises safety cells (21, 22) which are positioned and fixed close to each guiding device (8) such as to emit a beam F that is directed along a vertical axis outside of the guide (15) so that the beam is interrupted upon deformation of the flexible curtain or apron (5).
