Standard arrangement used on most machines. Sensing tension on both ends provides maximum sensitivity and eliminates sensing errors due to tension variation from edge to edge.
Useful on narrow web machines. Should not be used where roll face exceeds six inches.
WIRE OR FILAMENT
Similar to narrow web style. For tension in excess of two pounds.
For tensions less
than two
More economical sensing method. Not recommended for webs over 14 inches wide or machines where the web is run off center.
