Detecting end of film reliably

An adhesive strip is attached before the end of the film to let the operator know the roll will need to be changed soon. This is a reliable and simple method of automating the supply of film as an alternative to detecting the diameter of the roll. Depending on the material, an IME inductive proximity sensor can reliably detect metallic strips and a CSM color sensor can detect colored ones.
