Thanks to Dunlop’s highly experienced and dedicated team of engineers and rubber compound technicians, the days of cleats being torn off and sidewalls becoming detached have now been confined to history. Many manufacturers only use cold glue methods to attach sidewalls and cleats, which can result in premature failure. The secret behind the outstanding strength, flexibility and durability of Dunlop Super Strength sidewall and cleated belts is our hot vulcanisation technique, which permanently attaches sidewalls and cleats to the base belt. As a result we achieve a super-strength bond between the base belt and the profiles, creating a fully homogeneous belt. There are many more benefits of the hot vulcanisation process; belts can be used at higher temperatures, are less sensitive to smaller drum diameters, can withstand more extreme climatic changes and have strong adhesion due to specially developed compounds.
Only the very latest and most technically advanced production equipment is used in the manufacture of Dunlop Super-Strength Sidewall belts. Every possible aspect of the preparation and actual production is computer controlled. Nothing is left to chance. For example our proprietory production methods include special treatment that ensures maximum adhesion of sidewalls and cleats to the base belt.
Sidewall conveyor belts must be able to withstand the extremely high stress and repeated flexing that occurs in high capacity steep angle conveying. That is why our cross-stabilised base belts have been specifically designed by Dunlop engineers using the highest quality polyester fabrics to give higher rigidity values with very low elongation. The rubber covers protecting the carcass can be supplied in a range of qualities, including abrasion, oil and heat resistant and flame retardant. More information about our base belts can be found here.
Our sidewalls and cleats are manufactured using Dunlop rubber, reinforced by a diagonal layer of fabric that creates an excellent combination of elasticity and strength. In most cases the use of reinforcement within the sidewalls ensures maximum elongation (stretch) of the fabric at the flexing points while retaining a high tensile strength. Sidewalls and cleats can be supplied in a quality (for example flame retardant, oil resistant, etc) suitable for the application.
