Abstract: A vehicle tire with protruding nibs rolls down a ramp and into the device and begins to be rotated thereby. Knife means facing into the direction of rotation of the tire are skimmed over the left sidewall, the tread, and the right sidewall of the rotating tire at least once to trim off the nibs. Then paint is preferably sprayed upon the tire sidewalls, whereupon the processed tire is ejected from the device by application of brake means, preferably in combination with bumping the tire being ejected from the rear with another tire entering the device for processing. Cycling of the device may be automatically controlled. In the spray-painting operation, black paint may be applied to one sidewall as white wall protector is applied to the other.

Abstract: A process for making composite lumber products from generally cylindrical logs includes the steps of cutting a log radially into a plurality of sector-shaped pieces, rejoining two of the cut pieces by bonding them together along opposed radial faces such that the thin edge of one is approximately adjacent the thick edge of the other and then machining the bonded pair into a desired shape. The sector pair can be machined into a rectangle or a parallelogram. A plurality of compatible parallelograms or rectangles can then be edge bonded together into wider planar shapes after which the wider composite member can be rip cut longitudinally to selected widths. A method is described for proper sizing of the sector pieces depending upon log size and desired thickness of the composite lumber product. Taper is captured by reversing longitudinally one sector piece of each pair prior to bonding.The resulting composite product has many improved characteristics and offers a vertical grain pattern over its wider dimension.

Abstract: Apparatus for cutting work provided with centering means and supported adjacent a housing drivably mounted for rotation on a frame, the housing being arranged to support a floating, cutting assembly having a cutting head and centering means for initial alignment with the centering means on the work and subsequent cutting of the metal by the cutting head to remove an annular portion of material from the work.
