Belt Hot Splicing; Figure 13: Pneumatic Takeup Drive Belt Routing - Bastian Solutions RZPAC Installation And Maintenance Manual

5. Check that both routing rollers and the drive snub roller are set square to the drive frame and
approximately centered within their slots. Adjust if necessary before the belt is installed.
6. Using the routing shown in Figure 13: Pneumatic Takeup Drive Belt Routing, thread the belt
through the drive. The drive pulley will not turn easily with most gearmotor selections, so the belt
will need to be "pushed" rather than "pulled" past the pulley by providing slack just before the
pulley.
7. Reinstall all the guards that were removed.
8. Do not tension the belt at this stage. Refer to section 5.11.2 for belt tensioning instructions.
5.4.3

Belt Hot Splicing

1. If the belt uses a hot spliced joint, it will ship from the factory with prepared 10x80mm finger joints
cut at both ends. A scrap piece of belting will be taped to the finger joint to protect the fingers
during belt install.
2. See Table 2: Belt Hot Splicing Tools for a list of needed tools and suggested part numbers.
a. The hot press is required for belt splicing. Other models of hot press may be substituted
as long as the platen is large enough to accommodate the complete splice and the press
can be set to the correct temperature and pressure settings. Reference the user manual
of your hot press for appropriate operation instructions.
b. The guide block is required for belt alignment in the hot press. The listed part number is
specially designed for precise alignment. If other styles of guide block are used, great
care will be required to make sure the splice is straight.
c. The die cutter is a recommended tool in case the splice made with the prepared finger
joints needs to be re-done. Other models of die cutter may be substituted as long as they
can cut the required 10x80mm finger joint in a 4" (100mm) belt width. Reference the user
manual of your die cutter for appropriate operation instructions.
3. It is recommended that sites with a large number of hot-spliced belts own the tools in Table 2:
Belt Hot Splicing Tools for maintenance and repair purposes. Sites with only a few hot-spliced
belts may choose to hire a local belt service company instead of investing in the tooling and
required expertise.
Belt hot splicing requires significant expertise and skill to achieve a fully fused, straight
result. It is strongly recommended to make several practice splices with scrap belting
before attempting to make a finished splice on a conveyor, if the operator does not
already have experience in hot splicing belts.
