Measuring line speed of film or paper on a
production line
This application shows how to measure and
calculate line speed of measurement object moving down a
production line by the number of generated pulse and
roll diameter from a rotary encoder. The rotary encoder
is connected to a rolling shaft on a film production
line.
Deflection of film/paper can be prevented by
keeping the line speed of two rotary encoders constant which
are set
at two major points on a production line.
