TEXTILE CONVEYOR BELT SPLICE METHODS

Textile conveyor belts are spliced by vulcanization, by glueing or by means of mechanical fasteners.

 

In many regions of the world, mechanical fasteners are the first choice because it is a cheap and fast way of connecting two belt ends. Nevertheless, mechanical fasteners do not achieve the static and dynamic splice strengths of vulcanized joints.

HOT OR COLD SPLICING

A hot, vulcanized splice is usually the best option, because the chemical and physical process is like for the original belt. Done properly, the splice can last as long as the belt. Its dynamic efficiency will be significantly higher.

 

A cold splice can have an immediate cost advantage and be sufficient for low tension operations. For higher tensions, so thicker belts, the pressure may not be distributed equally. Done properly, a cold splice can achieve a service life close to that of a hot splice. It should not be used for warm conveyed material.

 

Both methods have the same splice geometry.

 

Steel cord conveyor belts cannot be spliced with cold glue or with mechanical fasteners.
