This automatic web splicer produces highly reliable splices and reduces waste while saving time and labor. The splicer can be integrated into new installations or retrofitted to existing lines. The unit can accommodate rolls up to 84 inches (1,828 mm) in diameter and 90 inches (2,285 mm) wide. Using the menu driven controls, the splice initiation can be automatically set to a preset roll diameter or a lineal measurement. Infeed idler rolls equalize the tension across the web and double the web length between the roll core and point of splicing, thereby allowing higher speeds to be maintained during the splicing process.
