Two-Ply Lamination
provides uniform belt
thickness, allowing consistent heat
transfer. Splices are staggered for
improved strength. This construction is
available on selected fabrics and
widths.
|
| Edge Reinforcement
is available with 2 inch PTFE / PTFE glass
fabric folded over & sewn with two rows of
stitching. Heat sealed PTFE film edges, and
1 inch wide fabric edges heat sealed on the
top surface are also available. Edge
reinforcement prevents unraveling of porous
belts and provides strong support for pin
guides and grommets. |
 |
 |
|
|
The axis of each
pulley and roller must be parallel to all
others and at right angles to the direction
of the belt travel. The shorter the distance
between pulleys, the greater the need for
accurate parallelism. Techniques that
improve tracking include belt position
sensing devices that provide for automatic
correction, and belt pin guides which
receive pulley grooves. |
|
Pin Guides.
Standard stainless steel
pin guides, one inch center to center
and one-half inch edge to center, are
available on one or both sides of any
belt. Edge reinforcements may be
necessary on some fabrics
Now Available - Silicone Guide
Strips. White silicone extruded
guide strips extend machinery life by
avoiding abrasive surface wear of
pulleys. These strips allow belts to
move smoothly, virtually gliding through
tracking grooves. Can be used as an edge
guide or a center guide.
