Abstract: Disclosed is a method and apparatus for shaping a top surface of a product, such as an antiperspirant or deodorant product, to have a compound-curved shape. The apparatus includes at least one cutting blade which moves inward and outward in a second direction while the product passes by in a first direction perpendicular to the second direction, such that the cutting blade cuts the top surface of the product to have a desired profile in the first direction. The cutting blade itself can have a desired profile along a third direction perpendicular to the first and second directions, to impart to the top surface of the product a desired profile in the third direction. A plurality of cutting blades can be used, to incrementally remove product material to form a final shaped product surface. The product cut off in forming the shaped surface can be reclaimed for re-use.

Abstract: A method and apparatus for shaping a solid body of soft material wherein the body is notched on one side, a rough cutter moves inwardly through the other side of the body to enter the closed end of the notch and sever body material without breaking, and a finish cutter than removes relatively little material to produce a finish cut.

Abstract: A draw-knife for producing keyways and for profiling workpiece bores comprising a knife bar whose head portion carries a cutting member which comprises two knife plates arranged side by side in the same plane and being coaxially adjustable, and an immobile knife plate provided behind the latter in the drawing direction of the draw-knife. The cutting edge of the immobile knife plate bridges a gap between the inner ends of the cutting edges of the two adjustable knife plates. The length of the cutting front of the cutting member of the draw-knife is changeable thus allowing one sole tool to adapt to any desired width and fit of the desired grooves or profiles.

Abstract: When a continuous cast slab is cut, such as by gas cutting, burrs tend to be caused at the cut edges. These burrs are removed by a plurality of edged cutting tools which are installed serially along the width of the slab to be treated. Each of the edged cutting tools may be selectively raised or tilted in the vertical direction or moved in the horizontal direction to substantially follow the warped or otherwise uneven surface on which the burrs are located. In this manner, substantially all of the burrs are exactly and completely removed.
