In the 1960s, self-regulating process belts, TRACKMATIC™ belts from GKD, were far more than just an innovation: External control units were made redundant, machines became more compact and service lives were raised considerably. This was all made possible by a new weave type that for the first time enabled rows of V-crimps on the underside of a process belt, while the top of the belt was still smooth. These V-crimps are guided in grooved rolls, which effectively prevents the process belts from running out of alignment. Since the market launch, we have in particular concentrated on enhancing the materials employed. For example, Teflon-coated wires are used as warp wires in the food production industry. For hygiene products we manufacture process belts with Kevlar warp wires which also allow high-speed production lines to be equipped with optimal reliability.
