Patents by Inventor Peter Daetwyler

Peter Daetwyler 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: 8635755
    Abstract: A method for producing doctor blades from metal, in particular from steel, the doctor blades to be produced having a reduced material thickness in a region of a working edge. The material thickness is essentially constant in the region of reduced material thickness. By a planing operation being used upon a basic body with an essentially constant material thickness, the region of reduced material thickness is generated. By the region of reduced material thickness being generated by means of a planing operation, an efficient and cost-effective method for the production of doctor blades is achieved.
    Type: Grant

  • Patent number: 5638751
    Abstract: A wiping blade, especially useful as a doctor blade for gravure printing and made from a single piece of unitary material, e.g., metal, is provided. The doctor blade has a top surface and a planar bottom surface spaced from the top surface. Front and rear longitudinal edges are spaced from and parallel to each other. The blade has a backup portion which has a first thickness and extends a first distance from the rear edge toward the front edge. The blade also has a doctor blade portion that extends a second distance from the backup portion toward the front edge and has a second thickness less than the first thickness. Furthermore, the doctor blade can include a blade tip portion that extends a third distance from the doctor blade portion to the front longitudinal edge and which has a third thickness less than the second thickness. The blade tip portion may also have an angled tip end at the front longitudinal edge angled upward from the planar bottom surface.
