The productivity of continuous web processing lines relies on the ability of the unwinding operation to consistently introduce new rolls of material into the process at full production speed and without tension upsets. The industry trends are toward higher line speeds processing thinner materials. The unwinding of thinner, more tension-sensitive materials at smaller diameters and higher speeds puts greater demands on the splicing operation. To meet today’s productivity requirements for continuous unwinding & splicing operations, it is important to understand the components of a splicer operation. Optimizing each component is critical to improving splicing efficiency and total productivity of the process line. This article will address the important components of the roll splicing operation and their effects on consistent and high-quality splices on a continuous roll to roll application.
