Abstract:
A method for marking defects in or on a substantially planar strip of polymeric film, wherein the defect is marked by firstly:a) illuminating substantially the width of the strip by a light source;b) detecting defects in or on said strip by a detector, wherein said strip extends along a plane which is adjacent to said light source and wherein light striking said strip is reproduced on said detector, and thereafter marking the defect by a marker which is placed in close proximity to said defect so as to indicate the position of the defect, wherein said marker is placed on a label, wherein said label is also provided with information corresponding to the dimensions and/or the position of said defect and that said label is attached onto said strip such that the proximate location of said marker indicates said position in both a longitudinal and a transverse axis of said planar strip.
