In today's technology, the power of mechanization has emerged in places where manpower is insufficient in order to meet the increasing needs at many facilities. With belt conveyor systems, it has become much easier to transport the material from one site to another in the facilities in terms of time, distance, and capacity. Since belt conveyors are a reliable and cost-effective system in material handling, the quality of the belt used should be carefully determined. It is important that the wear and tear that occurs on the belt over time is repaired quickly and effectively in order not to prolong the downtime in the plant. A small damage detected needs to be repaired immediately so that it does not cause bigger problems. In this study, vulcanization time, which is one of the parameters affecting the belt strength in belt splice made by vulcanization method, is discussed. By studying the effect of time on belt strength, it is aimed to extend the life of the belt splicing area. According to the test results, it has been observed that the vulcanization time has a positive effect on the tape strength and the usage of welding machine saves time in terms of faster use of the tape in the facility.
