Transback Backed Belts
Introduction
Transback belt backings
Modifying the characteristics of many TransDev timing belts by applying one
or more backings and enabling infinite different designs for conveying
applications. Specific properties such as high or low coefficient of friction,
soft, hard or compressible can all be achieved with a backing.
Using a thick backing affects the flexibility and hence the minimum pulley
diameter, but slotting the backing can improve the flexibility. We can bond
our backing materials to virtually any base belt for use as conveyor belts,
haul-off belts, puller belts, forming belts and nesting belts. Haul-off/puller
belts are mainly used in the plastics and cable industries to pull extruded
profiles. We can currently process belts to a length of 90 metres and to a
width of 600mm.

Special materials
Should you have a requirement for
a material with non-standard properties
please consult our Technical Department.
There may be a minimum quantity
requirement.
Please note:
• Abrasion resistance: the higher
the number the better
• Temperature range: also consider
temperature range of the base belt
Stress rating: see graph
• Material colour: subject to
change without notice

TransDev machined backings
Precision back, edge, face
grinding and pocketing
TransDev can grind any
face of a covered belt to
precision tolerances.
Belts up to 90 metres long
and 600mm wide can be
processed. Belts can be
pocketed as required for
component nesting.
Precision
sectional profiling
Backings can be crossprofiled
or slotted.
This can be for stress relief
or providing profiles for
high precision indexing
or positioning.
Lengthways
precision profiling
Backings can be ground
to any desired profile.
Belts with thicker
backings can be slotted
to relieve stress when
using small pulleys.
Tooth removal,
holes and perforations
Tooth removal from timing
belts is used to provide
clearances for mechanically
attached profiles or for use as a
vacuum groove. Vacuum
grooves can have Slip Face
bonded to the belt face to
reduce the coefficient of
friction. Holes and perforations
can be machined as required.
