  • ROTATABLY MOUNTED IDLER
    Publication number: 20220185609
    Abstract: In many continuously webbed machines, media is fed through the machine with rollers mounted to one or more rotating shafts. These shafts may be supported on each end with a cylindrical journal bearing. The rollers move at the same rate as the media to maintain traction with the media to control media position as it moves the media from one process to another through the sequence of processes in the webbed machine.

  • FORCE SENSOR
    Publication number: 20220187971
    Abstract: A force sensor includes at least one cavity defining at least two surfaces having different orientations. On each of said surfaces is disposed at least one respective detection structure sensitive to a pressure exerted on the corresponding surface. A resiliently deformable medium at least partially fills the cavity by coming into contact with the surfaces and defines a detection surface, on which a force to be detected is likely to be exerted. The application of this force is likely to generate stresses on each detection structure due to the transmission of forces by the medium.
