BELT SPLICING
Either vulcanized splices or mechanical
fasteners are recommended for
HBD/Thermoid conveyor belts. The
fastening method you select depends
on the particular requirements of the
conveyor system. Here are some
reasons for and against each method–
VULCANIZED SPLICES
1. The belt surface is smooth, an
important consideration in many
applications where other equipment
operates in conjunction with the belt.
2. If fine material is being handled, a
vulcanized splice is necessary to prevent
leakage at the joint.
3. Vulcanized splices allow the full rated
working tension of the belt to be utilized.
AIR CURING CHEMICAL SPLICES
Chemical systems of splicing provide an
alternative to the vulcanized splice. This
air-curing cold-splice system eliminates
the need for a vulcanizer and can be
made in areas that are not accessible
with a vulcanizer.
One company offering cold splice materials
and instructions is: REMA-TIP-TOP North
America, 200 Paris Ave., Northvale, NJ.

MECHANICAL FASTENERS
1. Require the least amount of time
for splicing.
2. The splice can be taken apart and
rejoined if pin style fasteners are used.
This should be considered if there is any
possibility the belt or the system will be
lengthened or shortened.
