The Science of Winding Paper Rolls

Abstract

In many cases paper products are of a wound roll format. The wound roll product must have integrity such that it does not slip internally or telescope in printing or other converting operations or in the hands of a consumer if the wound roll is the final format of the product. Winding models which predict internal stresses within wound rolls begun development over twenty’ years ago. The purpose of this paper is to (1) show how the models can be used to insure roll integrity and (2) show how paper properties can affect the integrity of the wound roll and (3) show recent developments in wound roll models.
