Mr. Myrzik, could you please explain what is meant by the term \"splicing\" in the context\nof conveyor belts?<\/p>\n
MYRZIK: \"Splicing\" is a high-quality technique for joining conveyor belts. This technique is\nused when installing a new conveyor belt or replacing a damaged section. The type of\nconveyor belt determines the splicing method used. Here are two examples: Hot vulcanization\nis used to securely splice two sections of steel cord belts. For fabric belts with several plies,\nhowever, a cold process can be used.<\/p>\n
Both processes aim to ensure a uniform thickness of the belt structure along its entire length.\nThis significantly reduces mechanical loads during the conveying process, such as those from\nscraper systems. As a result, the belts and other components have a longer service life. The\nbasis for this is the use of so-called stepped or finger splices. With finger splices, the prepared\nends of the belt layers interlock\u2014comparable to the interlocking fingers of two hands. When\nplaced on top of each other in opposite directions, they create a wide, stable connection zone\nthat enables homogeneous force transmission.<\/p>\n
In what ways does a professionally executed splicing process contribute to the safety\nand efficiency of a conveyor system?<\/p>\n
MYRZIK: A professional splicing process benefits the safety and efficiency of a conveyor\nsystem in several ways. For example, if the conveyor belt is damaged by wide cracks, it does not need to be replaced entirely. Not only does an insert save costs, it is also sustainable.\nAdditionally, such a repair usually takes less time. This means that the time during which the\nconveyor belt cannot be used is shorter than if a new order has to be placed. However, it is\nimportant that splices are carried out professionally because a poor splice can cause the conveyor belt to tear. Consequently, not only can conveyed goods be lost, but people and the\nsystem structure can also be damaged.<\/p>\n
What are the different splicing methods?<\/p>\n
MYRZIK: There are three main methods: mechanical bonding, hot vulcanization, and cold\nvulcanization. Mechanical bonding is only suitable as a temporary solution. We recommend\nhot vulcanization, cold splicing, or cold bonding. In hot vulcanization, the ends of the belt are\njoined using heat and pressure with the help of a vulcanizing press. This process can be used\nwith all belt types. However, there are exceptions if the belts are very small or narrow, in which\ncase a vulcanizing press cannot be used. In this case, cold splicing is the right choice. Here,\ntwo belt parts are joined together using special adhesives. It is important to strictly adhere to\nthe curing times.<\/p>\n
How long does a professional splicing of conveyor belts take?<\/p>\n
MYRZIK: Of course, this depends heavily on the strength and width of the belt, the size of the\nteam, and the local conditions. Larger connections take around 24 hours, while smaller ones\ntake around four hours. Cleanliness is a key success factor, though it is not always easy to\nmaintain in the close proximity of conveyor belt systems. On average, splicing the belt ends\non these systems takes two shifts. During the first shift, the surfaces are prepared, sanded,\nand cleaned. During the second shift, the conveyor belt ends can be assembled and\nvulcanized.<\/p>\n
How do you recognize high-quality work, and what characteristics do you look for?<\/p>\n
MYRZIK: These processes require extensive experience with different materials and selecting\nthe right ones. Additionally, the specified processing and curing times must be followed\nprecisely. For instance, if the temperature is incorrect during vulcanization, the joints may open\nagain after just a few weeks. Another indicator of quality is the absence of bubbles after\nvulcanization.

How durable are belt splices?<\/p>\n
MYRZIK: As a general rule, the splices last as long as the belt \u2014 typically eight years. We\ncontinuously test the quality of our splicing materials and their adherence to standard\nspecifications in the laboratory. Our results are 40 percent higher than the standard\nspecifications, and our material has a longer storage life compared to that of other\nmanufacturers. Each joint is labeled to show when and by whom it was created, so the joint's\nage can be checked at any time. Additionally, the MCUBE system from REMA TIP TOP helps\nsystem operators detect damage before it occurs and causes failures through live monitoring.<\/p>\n
Does REMA TIP TOP offer customer training courses on professional conveyor belt\nsplicing?<\/p>\n
MYRZIK: Yes, our customers' qualifications are very important to us. We regularly offer training\ncourses at our customers' premises around the world, including in Germany, the Middle East,\nChile, and Brazil. We have teams around the world to support customers in maintaining their\nconveyor systems in the best possible way, ensuring sustainable and cost-efficient operation. There are also two permanent training locations in Poland: For textile belts, it is COBRA\nEurope, which is part of the REMA TIP TOP Group. For steel cord belts, training takes place\nat REMA TIP TOP Service, the Polish subsidiary.<\/p>","protected":false},"excerpt":{"rendered":"
