Abstract

Procedure for determining the presence, in a given region, of an edge of a sheet or tape of a transparent material that has a predetermined orientation and that has a geometry that satisfies certain conditions, characterized by the fact that It projects a beam of light rays in this region in a direction such that, when a sheet or tape that has this orientation and has an edge with that geometry is present in that region, the light rays penetrate inside the edge to determine through one side of the sheet or tape at an acute angle and emerge at an acute angle from the opposite side of the sheet or tape, after being deflected by the edge and by the fact that it is detected the existence of emerging light rays.
