The purpose of a winder is to convert the large diameter, machine-width parent reels of paper or board produced on a paper or board machine into finished roll sets ready for converting or shipping. Winder slitters are used to cut parent reels into various roll widths and trim off the edges of the sheet in order to meet customer requirements. This module will describe common slitting methods and recognize safety guidelines applicable to winder slitters and slitter sections.
