Laser Switch Location
The Drive Turn Hem Rolls are equipped with a laser switch to detect the notches in
the sheet. Using standard notches for HVAC, this laser switch (both sender and
receiver) are positioned 3” from the machine plate to the center line of the

Dependent on the notch type, this switch may need to be moved inward or
outward. If they need to be moved they must be moved the same, meaning top and
bottom switches moved together.
