Lateral mechanics of baggy webs at low tensions
Abstract
Existing mathematical models describing lateral movement of webs such as paper or plastic film, assume that the entire width of the web is carrying tension or that the web is capable of supporting compressive stresses. For many webs this is not true. Thus a mathematical theory describing lateral movement of baggy webs which do not support compressive stresses have been derived. It is shown that the mechanics of these webs are described by a nonlinear fourth order differential equation for which a numerical solution has been developed. Results show that the lateral deflection of baggy webs is significantly affected by tension at the lower levels of tension.
