Because of the high volume of rolls produced on GPPE’s rewinders, a roll processing ffered to minimize downstream labor requirements. The core tolerances available through modern core production result in core offset in typical rewind applications. For example, a converter running 2.25-inch (57mm) wide POS rolls on a typical 54-inch rewinder can have as much as 3/16-inch (nearly 5mm) of core offset.With rolls coming off the rewinder at rates of over 100 per minute, an automated solution for this problem is required. The GPPE roll processing hat solution. This roll processing machine accepts roll sets from the GPPE rewinder, individually separates them, orients them with the core in a vertical position, aligns offset cores using a small press and conveys the finished rolls to further downstream packaging.
