a spreading or widening action on a moving web of paper,
film, textiles, etc. To obtain the best results, use the
guidelines and installation suggestions below.
Perma-Bow™
The
Perma-Bow™ has a bow of fixed dimensions and is widely
used where operating conditions remain fairly constant.
The amount of bow depends on the web material, face width,
tension and arc of contact between the material and the
bowed roll.
Ajusta-Bow™
 By
virtue of the adjustable bow feature, the Ajusta-Bow™
enables the roll to be effective under a wide variety of
operating conditions.
