Optimizing splice geometry in multiply conveyor belts with respect to stress in adhesive bonds

This paper presents the results of investigations into stress distribution in the adhesive bonds of multiply conveyor belt splices. The splices were cold-vulcanized with the use of chemically hardening glues having various strength parameters. The research results demonstrated that the length of splices may be reduced without the risk of lowering their tensile strength and fatigue life. The paper presents stress values in adhesive joints of various belt types and the influence that the properties of belts, splices and splicing materials have on stress values in the adhesive bond of the splice.
