Eurobelt  EPX  EXTRUDED PLASTIC CONVEYOR BELTING

JOINING INSTRUCTIONS USING HEAT GUN AND WELDING ROD

The EPX range of polyester and polyurethane conveyor belting is manufactured from homogenous thermoplastic materials which are easily joined using low cost equipment. The essential equipment consists of a grooved steel or aluminium plate, clamps, hot air gun with special nozzle, and a trimming knife, router or grinder.

The method is as follows:

1)

Align the belt ends, ensuring the belt is straight and true, cut ends 90 degree or at a 60 degrees angle for smaller pulleys.

2)

A 60 degree welding groove needs to be prepared by beveling the ends 30 degrees.

3)

Re-align and clamp the prepared ends in position using a solid base and clamping bars right across both belt ends. Leaving a 40 mm gap for welding is recommended. Two 100 mm packers next to the belt are also required.

 4)

The next step is to fill in the V-groove using the hot air gun with the special nozzle and a welding rod, adhering to the following basic fundamentals:

a)

 Hot air gun temperature approximately 400 ° C

b)

 Keep a constant pressure on the nozzle.

c)

 Angle of the heat gun between 30 and 45 degrees.

d)

 Weld speed to be slow and steady.

e)

 Leave to cool to ambient temperature (5-10 minutes)

5)

Take away the clamps and remove the excess welding rod using a knife, die grinder or a router with a flat router bit.

6)

Cut the packers from the belt and remove excess weld penetration from the underside, using a trimming knife.

7)

Try and break the packers, if they easily break, start over from step 1.
