Pulling up the belt

CAUTION
NOTE
After the conveyor system has been assembled, pull up the belt.
Proceed as follows:
§
Remove the packing material from the belt.
§
Pull the belt (the chain is already connected) to the deflection wheel at the beginning of the conveyor
system.
§
Put the belt onto the conveyor rollers under the conveyor system and move along the drive roller until it
will reach the limit rocker switch at the beginning of the belt.
§
If the chain is not fastened, the belt can be moved over the drive rollers in reverse order. There is no
mandatory order for laying 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 belt.
§
Join both ends of the belt together and fasten them 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, it needs to be stretched:
§
Mark a distance of 1000 mm on the belt with a pencil (no pen).
NOTE
§
The belt can be adjusted appropriately by turning both tensioning nuts on the threaded rods at the
deflection.
§
The belt must be stretched in such a way that the distance between both ends of the belt is not more
than 0.08" (2 mm).
§
Trim any plastic strips protruding from the sides to the width of the belt using robust scissors after
stretching 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
Overstretching the belt can lead to its destruction.
Ensure that the belt is not overstretched.
Arranging the belt
Ensure 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 39.57 to 39.65" (1,005 to 1,007
mm) at a strain from 0.5 to 0.7% (pay attention to the marks made with the
pencil).
