materials, acids and chemicals are also stored
or used. Motor-control rooms, welding shops,
and other places where ozone is generated
should likewise be avoided. A belt should not
be permitted to rest on a concrete floor. If it is
necessary to lay a belt on the floor, use a
pallet or a cradle.
Belts which are not endless should be stored
in rolls. Once thoroughly cleaned and dried, it
is good practice to dust a belt with tire talc or
to insert kraft paper between the layers when
rolling it up. Care should be taken not to roll a
belt too tightly. Be sure the interior diameter
of the roll is sufficiently large to avoid any
possible carcass damage or warping.
The belt should be rolled evenly to
avoid telescoping and warping. Exces-
sive flexing or sharp bends of any sort
are to be avoided. Rolls should not be
stood on edge or leaned against a wall.
Small endless belts may be hung up on a
dowel or a peg for storage. It is advisable
to rotate the belt occasionally to avoid a
constant flex or bend at one point. Larger
endless belts may be stored flat, doubling
them over as necessary. It is advisable
when doubling a belt over to be sure that
the edges of the belt are in line to avoid
any warping. As above, it is good practice to
rotate and repile the belt occasionally to avoid
constant flexing or bending at any point.
Bends should be made as large as possible to
avoid cracking the carcass.
Installation
Once the roll of belting has been transported
to the point of installation it should be
mounted on a suitable shaft for unrolling and
threading onto the conveyor. Conveyor belt-
ing is normally rolled at the factory with the
carrying side out. Consequently, in mounting
the roll, the belt must lead off the top of the
roll if it is being pulled onto the troughing or
carrying idlers but off the bottom of the roll if
it is being pulled onto the return idlers. The
illustrations below represent suitable methods
of mounting and stringing belt for each case.
Note: Temporary flat roll at
bend point, as roll is pulled
onto troughing idlers
In some cases, such as in the mines where
head room does not permit maneuvering a
roll, the belt may have to be pulled off the roll
and reefed (Left). Extreme care should be
exercised to see that the loops have large
bends to avoid kinking or placing undue strain
on the belt. No weight should ever be placed
on the belt when it is in this position. Another
method of handling belting under such condi-
tions is to lay the roll on a turntable with a
vertical spindle.
