Winding is an integral operation in almost every web handling processes. Center-wounding are suitable and a general scheme in winding systems. However, the internal stresses within center-wound rolls can cause damage such as buckling, spoking, cinching, etc. Wound roll quality and performance are known to be related to distribution of in-roll stresses. It is therefore necessary to analyze the relationship between taper tension in winding section and internal stress distribution within center-wound roll to prevent the potential winding failure (starring, buckling, telescoping, etc.). In this study, a new taper tension control method for producing high quality wound roll was developed. The new method was induced from analyzing the winding mechanism by using the stress model in center-wound rolls, nip induced tension model, taper tension profile-telescoping relationship, and taper tension type-internal stresses relationship, etc. Auto taper tension profile making method for avoiding the damage (telescoping, buckling, cinching, etc.) is presented. The experimental results show that the proposed method is very useful.
