Abstract
A system for establishing the lateral position of a web without requiring the web path to change direction. The system utilizes a support surface that is curved in its transverse direction concave towards the web, a guide extending longitudinally along the surface, and a roller that is positioned against the support surface so that the web will be urged laterally against the guide and will conform to the curvature of the surface, thereby increasing the lateral column strength of the web.
Claims15
A lateral constraint system for accurately positioning a web, said system comprises:
- a longitudinal web support surface that is curved in its transverse direction concave towards the web;
- a guide extending longitudinally along said surface;
- and
- a roller positioned against said surface;
- means for deforming said roller, when rotated to urge a web laterally against said guide so that the web will conform to the curvature of said surface to increase the strength of the web.
