Title: Juregen Ries and a Device for Folding Sheets

Introduction

Juregen Ries is an inventor associated with Ostfildern, Germany, and Eastman Kodak Company. His recorded patent concerns a sheet-folding device designed to guide and grip folded products while reducing unnecessary load on the roller bearings.

Latest Patents

Ries is credited with 1 patent, titled “Device for Folding Sheets.” The invention arranges four pre-folding and pinch rollers of identical diameter in sequence along the folding direction. The second pre-folding roller and the second pinch roller are mounted in fixed positions, while the first pre-folding roller is carried by pivoting lever arms.

Connecting arms attached to the first roller’s bearings support the other pinch roller. Springs and fixed stops position the components so that the rollers remain separated when no folding is underway, preventing the bearings from being loaded unnecessarily. As a folded product exits the pre-folding rollers, it lifts the connecting arms from their stops. This movement sets a gap at the pinch rollers according to the product’s thickness, helping them grip the product.

Career Highlights

The patent reflects Ries’s work on mechanical arrangements for sheet folding, particularly the coordination of rollers and movable supports. Its design addresses both bearing load during idle periods and reliable handling of products of varying thicknesses.

Collaborations

Ries is associated with Eastman Kodak Company. Arno Ebner is identified as a coworker.

Conclusion

Juregen Ries’s patented folding device combines spring-loaded linkages, fixed stops, and coordinated rollers to support efficient product gripping while limiting unnecessary bearing loads.
