Pulling up the belt

ATTENTION
NOTE
After the conveyor system has been assembled, pull up the belt.
Proceed as follows:
§
Remove the packing material from the belt.
§
Remove the boxes at the beginning and at the end of the belt and place the belt on the top of the
conveyor system.
§
Pull the belt (the chain is already connected) to the deflection pulley at the beginning of the conveyor
system.
§
Put the belt onto the conveyor rollers under the conveyor system and move along the driving roller
until it will reach the limit rocker switch at the beginning of the belt.
§
If the chains are not fastened, you can move the belt over the driving rollers in the reversed
sequence. There is no obligatory sequence how to arrange the belt.
§
Pull the belt over the upper side until the ends of the belt are facing each other at the middle of the
conveyor system.
§
Join both ends of the belt together and fasten with the plastic strips (connection elements). The
plastic strips hold now the both ends of the belt together.
§
Check the position of the belt and adjust it so that it lies exactly at the top of the conveyor system.
4.2.3

Stretching the belt

After the belt has been fastened, you have to stretch it:
§
Mark a distance of 39'' (1000 mm) on the belt with a pencil (no pen).
NOTE
§
To adjust appropriately the belt turn both tensioning nuts on the threaded rods at the deflection.
§
The belt must be stretched so that the clearance between both ends of the belt is not more that 0.08''
(2 mm).
§
After you have stretched the belt appropriately, if needed cut the plastic strips protruding on the sides
so that they are uniform with the width of the belt.
§
Finally, scorch and seal these both places with a small flame (e.g., with a lighter), so that the plastic
strips cannot slip out any more.

Damage to property
Do not overstretch the belt, otherwise this will ruin it.
Make sure that the belt is not overstretched.
Arranging the belt
Make sure that the smooth PVC surface is at the top when unrolling and
arranging the belt while the rough surface is on the rollers.
Do not twist the belt when arranging it.
Length of the belt
A length of a perfectly stretched belt is from 39.5 to 39.6'' (1005 to 1007 mm)
at a strain from 0.5 to 0.7% (pay attention to the marks made with the pencil).
