Windmöller & Hölscher KG

Methods and equipment for continuously shaping plastic materials by forcing them through a die, often involving screw extruders, heating elements, and downstream calibration.

Systems and methods for real-time sensing, modeling, and closed-loop control of additive manufacturing parameters to ensure part quality, consistency, and process efficiency. This includes thermal management, atmospheric regulation, and precise material deposition.

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.

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.

Systems and methods for accurately controlling the volume, location, and characteristics of sprayed fluids, often involving sensors, feedback, or specific nozzle geometries for precise application.

Techniques for combining multiple materials or layers, often with specialized surface treatments, coatings, or assembly methods, to create functional or aesthetically enhanced plastic articles, including consumer goods and encapsulated electronics.

Multi-layer polymer films engineered to provide superior barrier properties against gases (e.g., oxygen), moisture, or aromas, often incorporating heat-sealing or resealing mechanisms for food and product preservation.

Processes involving the application of heat and pressure to shape thermoplastic or elastomeric materials, often using molds or presses, to achieve specific forms or material properties.

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.
