If a Nylon (polyamide) layer is present, it is combined into a whole using a chemical bonding method. The ends of the belt are skived to a wedge shape, one end of the belt from the top, the other from the underside, and bonded together using an adhesive system, heat and pressure. This is a very strong welding method, and provided the joining procedure is properly done, at room temperature the ...

· This method, described generally above under "Activated Gas Surface Treatment of Polymers," has been used successfully with RTV vinyladditiontype silicone rubber, using excited oxygen plasma. This treatment permitted the use of an epoxy adhesive for bonding. Usually, cured RTV silicones are considered unbondable by conventional adhesives such as epoxies.

The splicing process includes preparation and implementation of hot vulcanisation using special vulcanising devices. Hot plates positioned above and underneath the conveyor belt splice apply heat and pressure simultaneously to the splice. The combined heating method for hot vulcanisation of steel cord conveyor belts described in this paper uses the steel cords, which are embedded in the ...

The hot vulcanising method utilises heat and pressure to mend sections of a conveyor belt. Hot vulcanisation splices are heated and cured under pressure with a vulcanising press. The damaged portion of belt is carefully trimmed or removed. A new section repaired and bonded in place using cement or other adhesives.
