Richard SCHÄR has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9215878
    Abstract: The invention relates to a method and device for continuous production of articles including at least two different types from a pasty mass. The mass is introduced into a processor unit by a supply unit, processed in the processor unit and transported further thereby, whereupon an adjunct is added by a metering unit to the mass transported through the processor unit. The mixing of the adjunct introduced to the mass is carried out by a mixing unit with mixing elements located downstream of the processor unit. The mass with provided adjunct is formed by a forming unit into individual articles downstream of the mixing unit. According to the invention, the metering of the adjunct is carried out in a sequence of metering conditions with at least two different metering conditions, wherein the metering unit, for a given metering condition, introduces the adjunct to the mass at a given metering rate.

  • Patent number: 7255223
    Abstract: A transport device for transporting a transportable product, especially a bulk-type product, includes an essentially cylindrical chamber containing at least one shaft which extends along the cylindrical chamber and comprises a plurality of first transport elements for transporting products in a product transport direction. The transport elements extending radially outwards from the shaft and are respectively connected to the shaft at connection points on the surface thereof. The individual connection points are located along a helical line on the surface of the shaft and the plurality of first transport elements form a first path which corresponds to the helical line and comprises a first discontinuous section extending in a helical manner around the surface of the shaft. Other elements are arranged at least in partial regions of the first path, such elements protruding into the first path.
