ABSTRACT:
This invention is the means of support for rollers on a roller type press. This means of support is the configuration of four cables, straps or other suitable material under tension in relation to two rollers and a bed. Rotation is applied to either roller, the cables transfer the rotation to the opposing roller, supply the pressure between the rollers and guide the rollers as a set across the bed. The press can take many forms to provide an economical device, capable of many of the less demanding applications.
