I am looking into techniques for controlling the width of the film in blown film manufacturing process. I intend to measure the width of the film after collapsing and then carry out the control action.
Identifying the edges of the film and then calculating the width seems to be the way to go for the width measurement purpose. Since the web would be transparent, I was thinking of either using diffuse type of photoelectric sensors, or a would a photoelectric light grid make more sense?
Is this the right way to go? What more do I need to look into in this application?
Thanks in advance for any ideas, guidelines, help.
