Mechanics of Wrinkling, 1996 Finishing and Converting Conference Proceedings

Finishing Technologies, Inc.

Wrinkling is a common problem with thin webs of almost any material. This paper shows how all wrinkling is a compressive buckling of the web induced by either CD compression or inplane shear stresses. Common causes of wrinkling are then discussed which include roll(er) misalignment, deflection and diametral variations; constrained expansion, as well as residual stresses of manufacturing. Wrinkle removal via web flattening and web spreading are briefly reviewed.
