  • Low profile hardwood flooring strip and method of manufacture
    Patent number: 5823240
    Abstract: A method of producing a hardwood flooring product, including the steps of processing a strip of raw wood into a blank having a predetermined thickness and width, and top and bottom surfaces defining parallel planes relative to each other, and splitting the blank along the width of the blank from one side to the other to form two low profile flooring strips having the same width as the blank and a thickness less than one-half the thickness of the blank. The splitting step includes the steps of providing first and second circular saw blades mounted on spaced-apart vertical axes for rotation in a single plane intermediate and parallel to the planes of the top and bottom surfaces of the blank and positioning the blank on conveying means upstream from the saw blades with the plane of rotation of the saw blades intermediate and parallel to the planes of the top and bottom surfaces of the blank for movement of the blank from an upstream position to a downstream position relative to the saw blades.
    Type: Grant
    Filed: January 23, 1997
    Date of Patent: October 20, 1998
    Assignee: Triangle Pacific Corporation
