  • Patent number: 10537897
    Abstract: A grinding machine includes a slight gyration module for driving a homogeneous container to undergo an X-axial motion and a Y-axial motion within ±1-3 mm distance, a homogeneous-stick rotation module for rotating a homogeneous stick in the homogeneous container so as to generate an eccentric motion between the homogeneous stick and the homogeneous container, and a homogeneous-stick vertical movement module for vertically moving the homogeneous stick with respect to the homogeneous container. When the homogeneous stick is lowered into the homogeneous container by the homogeneous-stick vertical movement module, an eccentric motion with a 1-3 mm radius of gyration can be activated between the homogeneous container and the homogeneous stick so as to carry out the grinding in a tiny slim space between the homogeneous container and the homogeneous stick; such that the grinding efficiency of the grinding machine can be substantially enhanced.

  • Patent number: 10524544
    Abstract: Systems and methods are provided for collecting three-dimensional surface data of a lasted shoe upper that is mated with a sole that is configured for the lasted upper. The mated three-dimensional data is used with three-dimensional data of the lasted shoe upper in an unmated configuration with the sole to determine a location of an edge defined by the intersection of the lasted upper and the sole when mated. The bite line identifies an edge where the upper and a sole assembly will intersect on a finished shoe, which may represent a bounding line for application of adhesive to the lasted upper for boding the sole thereto.
