Systems and methods are disclosed herein for laser kerfed veneers. A laser may be used to produce kerf lines in thin veneers. The settings of the laser may be adjusted to adjust the width and depth of the kerf lines. The width and depth of the kerf lines may be selected in order to provide sufficient strength to the veneer while decreasing telegraphing.

Described are wooden coil springs, including those made of non-compressed wood, and mattresses with such coil springs. Also described is a method of producing a coil spring made of non-compressed wood, which includes winding a slat on reel, steaming and drying to produce the wooden coil spring. Such a coil spring may have a cylindrical shape, a cone shape or a truncated cone shape, and may have a substantially perpendicular end turn with respect to the longitudinal axis of the coil spring.

The present invention is a material forming apparatus that includes a piece of material that is a piece of laminated wood, a cover sheet made of plastic material, a flexible bed, a plurality of bed arms and a plurality of drive gears. The material forming apparatus also includes a numerical digital display, a plurality of roller clamps, one or more cranks with a grasping knob and a plurality of pivoting arms that are rotated by rotation of the drive gears and move the bed arms to force the flexible bed and the piece of material into a desired arc radius.

A method for forming of a building panel with a surface including a thermosetting resin such that tension created during curing of the surface is reduced or eliminated.
摘要:
A fiberboard panel is formed from at least one corrugated sheet of molded cellulose fiber material having alternating ribs and grooves. Spaced slits are cut through the ribs on one face of the sheet and terminate short of the opposite face so as to form at least one slotted portion of more flexibility which may be bent to form a curve. The corrugated sheet is sandwiched between two flat sheets of the same material to form a composite panel. The corrugated sheet or panel is formed by a wet processing method including successive cold and hot press steps in which a wet mat is pressed between an opposing perforated platen and non-perforated, elastomeric material platen of cross-sectional shape substantially matching the desired panel shape and dimensions.

A method of processing a wooden piece into a predetermined shape by compressing the wooden piece, includes bending a raw-material piece which is a wooden piece to be processed and is placed in a humid condition of high temperature, cutting out a blank-material piece from the raw-material piece bent in the bending so that the blank-material piece includes at least a part of a bent portion of the raw-material piece, and compressing the blank-material piece cut out in the cutting out in a water vapor atmosphere of a temperature and a pressure higher than those of an atmospheric air.

The invention allows the realization of parts, longitudinally or transversely curved, of large dimensions, by assembling boards of solid wood side by side, with glue, and to afterward arch the resulting part. The loss of solid wood is then decreased a lot since it is thus possible to assemble several wood boards of various widths together. It allows the realization of final curved parts of almost unlimited dimension, dimension whereas dimensions are usually limited by the width of the sawing, or, in other words, by the thickness of the trees. Here, the limit is situated at the level of the capacity of equipments used to bend solid wood.

摘要:
A wooden member fabrication method which, by a simple process, can enable greater stability of shape subsequent to processing and uniformity of color tone. A wooden original piece with a long form has a hole thereinside which extends in the length direction. Corner portions are chamfered and radial direction thicknesses are substantially constrained to a certain range. An outer periphery of this wooden original piece is compression-deformed in directions toward an axial central portion and the outer periphery is thus made an arc surface. Because of the chamfering, radial direction thicknesses of the wooden original piece are constrained, and differences by location between compression ratios can be suppressed.

The invention relates to a profile of round or sawn timber and a method for producing the same. Such profiles can be produced essentially from all types of wood of coniferous trees and wood of deciduous trees, including low-grade wood of coniferous trees (secondary products, weak round timber), which can be obtained in large quantities in forestry. The inventive profile has a considerably larger load capacity compared to cross-sections of solid wood, for the same volume of wood. The wood as raw material is used to the maximum.
