Latest Patents
One of his latest patents is titled "Method and machine for versatile stitching." This invention provides a method and machine for controlling the orientation of one or more sewing instrumentalities concerning a workpiece. It allows for the rotation of sewing instruments about an axis perpendicular to the workpiece's movement. The invention also enables separate and independent control of each sewing instrumentality, allowing for the inoperability of one or both needles during continuous operation. Additionally, it offers manipulation of the thread associated with each sewing instrumentality, facilitating a pullback of the thread. This principle can also be applied to other tools that perform functions such as marking, folding, pinking, or perforating.
Another notable patent is "Apparatus for preparing pattern control tapes." This apparatus digitizes a pattern using the computer controller and motor driver of an x-y table in an automatic sewing machine. A manually operated control stick is connected to the controller, sending command signals to the motor drivers. A viewer projects a pattern onto a small screen, allowing the operator to move the x-y table through the desired pattern, which is recorded in the computer for generating a control tape.
