Best Practice Number 2
Use the proper ply knives and techniques to avoid nicking the adjacent fabric plies
while stripping down the belt.
Only one ply is cut.
The adjacent ply is not
harmed in any way.
Nicking the adjacent fabric ply effectively reduces the tension
rating of the belt, because the tension members (warp cords)
are disabled if they are cut or nicked. Top splicers use top
quality tools such as the correct single-ply knives designed
specifically for this operation. Utility knives are not acceptable
and must not be used for this precise operation.
Best Practice Number 3
Buff the rubber surfaces only. Never directly buff the fabric.
The fabric plies of all Continental ContiTech belts are coated
with various “dip” coats that enhance the adhesion of the
rubber to the fabric. These dip coats should not be buffed
off when preparing the belt splice. Reduced ply and cover
adhesion will result. If residual rubber must be buffed off after
stripping down the step, it must be done carefully so that
the buffer wheel does not actually touch the fabric. Severe
overbuffing will reduce belt strength and integrity by damaging
both warp and fill cords. The buffer wheel should not exceed
2000 rpm. A fabric cement known as “kicker” should be used to
replace the dip on exposed fabric.
