VALMET AB

Systems and methods for precisely measuring, monitoring, and regulating the longitudinal tension in continuous webs of material during roll-to-roll processes to prevent defects, reduce waste, and ensure consistent product quality.

Apparatus and methods for automatically winding or unwinding continuous materials such as webs, cables, conduits, or yarns onto or from spools, reels, or bobbins, including aspects like layering, coreless winding, and material supply.

Technologies for maintaining the correct path and alignment of webs or individual sheets during conveyance, including mechanisms for steering, correcting positional deviations, and managing static electricity.

Techniques for building three-dimensional metal objects layer-by-layer using metal powders, including powder bed fusion, binder jetting, and directed energy deposition. This theme encompasses process mechanics, equipment design, and operational control for AM systems.

Methods and systems for uniquely identifying individual units of material (e.g., yarn spindles, winding spools, bobbins) and monitoring their performance or status within a material handling process, often using sensors and coding.

Developing advanced bioreactor designs, fermentation strategies, and downstream processing techniques to optimize yield, purity, and efficiency of biotechnological production.

Technologies and systems for removing unwanted components or separating desired gases from a mixed gas stream, including adsorption, absorption, and membrane-based methods.

Engineering approaches to improve the efficiency, control, and performance of chemical reactors, encompassing continuous processes, heat exchange integration, and specialized reactor configurations for various chemical transformations.

Membrane-based separation for water purification, contaminant removal, desalination, and wastewater treatment, including reverse osmosis, ultrafiltration, and forward osmosis modules.

Production of materials where properties vary continuously or discontinuously through the volume, often achieved by combining different powders or applying specialized coatings like thermal sprays to enhance surface hardness, wear resistance, or thermal properties.

Systems that perform operations like cutting, folding, binding, or applying liquids to sheets or webs, often integrated within larger production lines such as printing or image forming apparatuses.

Innovations in the physical structure, materials, support mechanisms, and operational monitoring of conveyor belts to improve durability, cleanliness, safety, or specific handling capabilities, including specialized drive mechanisms.
