Roller
Preparation:
 The surfaces
of the roll to be covered should be smooth, clean, and dry. Although it is not
necessary to turn or grind the roller surface down, foreign material such as
oil, loose scale, product build-up, etc. must be removed (this is best
accomplished by using non-oil base solvent such as acetone or toluene). Slip
the tubing onto the roller carefully so as to avoid nicks, creases or
scratches. Trim tubing to length, leaving at least two inches extra on each end
of roll surface.
A heat source is required to shrink the tubing onto the
roll to be covered. A commercial hot air gun capable of delivering temperatures
between 500°F and 1000°F is adequate. Two heat guns are recommended to
ensure a smooth, uniform covering without wrinkling. Additionally, the roller
and the tube should be rotated at a fairly uniform speed.
To determine Roll Cover
size:
Measure the diameter and
use the nominal diameters listed below to detrmine the appropriate roll cover
size. allow 3" of extra roll cover length per 100" roll face for possible
shortening and an additional 2 or 3 inches for end cuffs. Maximum Temperature
use 400°F. For Temperatures up to 500°F ask for PFA
Material. |
