Abstract: A method of chamfering the outer peripheral edges of plate members comprises stacking the plate members in face-to-face vertically aligned relation so that for each two adjacent plate members the upper outer peripheral edge of the lower plate member opposes the lower outer peripheral edge of the upper plate member, detecting the boundary between two adjacent plate members in the stack, positioning a rotary chamfering tool in response to detection of the boundary, and moving the rotary chamfering tool relative to the outer peripheral edges of the two adjacent plate members to simultaneously chamfer the upper edge of the lower plate member and the lower edge of the upper plate member. The detecting, positioning and chamfering steps are repeated for each two adjacent plate members in the stack to thereby chamfer both the upper and lower edges of the stacked plate members.

The apparatus for cutting boards from tree trunks comprises guide rollers for advancing a trunk in a longitudinal direction, saw units adapted to move in a vertical and in a longitudinal directions to produce the transverse cuts and saw blades movable in the longitudinal direction to produce the longitudinal cuts after the transversal cuts have been made.

Abstract: Process and apparatus for cutting an elongate complex structure composed of materials having different properties, e.g. a liner and a core which are relatively soft and flexible and susceptible to rupture or crushing and a facing of hard material such as a metal plate. The facing may have an upwardly turned portion, flange portion and groove portion at each side thereof. A carriage and a base frame are movable in the direction of the travel of the complex structure and in the direction perpendicular thereto, respectively. Various types of cutters are mounted on the carriage. The complex structure is instantaneously cut in the direction of the width thereof while it is travelling at a high speed. The cut composite structure has smooth and fine cut edges, and is useful for e.g. a siding of a building.

Abstract: A method and apparatus for trimming an elongated article are disclosed by which the article is notched at longitudinally spaced locations and material spanning adjacent notches trimmed from the article as discrete strips.

Abstract: This invention relates to a device for removing fused slags on slabs wherein <-shaped cutters with the front center thereof being the apex are disposed on the front and rear positions of a tool rest being vertically movable with a required spacing and being close to the undersurface of the slab, respectively. At least the rear cutter is biased upwardly by a spring mounted in the lower portion of the tool rest. At the same time the shear point in the rear cutter is made to be somewhat higher than that of the front cutter in order to cut out the fused slags deposited on the undersurface of the slab on a transferring roller table with a prescribed length. If it is arranged in such a way that a water-cooling means for water-cooling the deposited portion of the fused dross is disposed before and behind the above device for removing fused slags on slabs, respectively, to cut off the cured dross, the fused slags can more effectively be removed.

Abstract: An anti-skiving device used for beveling an edge of photographic film so that when the film is processed the emulsion or anti-halation backing on the base of the photographic film will not flake or skive. The device eliminates flaked or skived material from the edge of the film from being processed on the film itself, which heretofore caused an unsightly appearance on the processed film.

Abstract: A machine for cutting grooves in foam workpieces includes a plurality of vertically spaced U-shaped cutting wires mounted on pairs of mounting posts. One leg of each U-shaped wire is mounted on one post, while the other leg is mounted on the other post. The posts are mounted on a frame so as to be adjustable in spacing and vertical position with respect to each other, so the widths of the grooves can thereby be adjusted. Horizontal slice-cutting wires are provided behind the groove-cutting wires so that grooves and slices can be cut simultaneously. The slice-cutting wires are aligned at an angle with the vertical so that each slice-cutting wire exits the workpiece before all those beneath it. One version produces tongue-and-groove sheet, while ship-lap sheets are produced by the other version.

Abstract: A method of maintaining edge strength of a piece of glass i.e. preventing unintentional damage such as chips and/or scratches to the edges of the piece of glass during handling, processing and/or shipping is disclosed. A sheet of glass having dimensions greater than the desired size of the piece of glass is cut from a glass ribbon. The sheet of glass is pseudosubsurface scored or subsurface scored within the edges to define the piece of glass and to provide trim around the piece of glass which trim protects the edges of the piece of glass against unintentional damage. Thereafter, the sheet of glass is stored or processed, e.g., coating a surface of the sheet of glass with a transparent metal coating. The trim is removed from the sheet of glass at a fabrication station and the piece of glass having edges free of unintentional damage is used in the fabrication of a product e.g., a multiple glazed unit.
