摘要： A method for producing multi-ply, parallel-laminated pine lumber of 1 1/2 inch thickness from one-quarter inch thick rotary peeled veneers. The method is characterized by a carefully designed lay-up of plies whereby the butt-joints within individual plies are selectively located to achieve, overall, a rather precisely defined, staggered, butt-joint array with respect particularly to the butt-joints within immediately adjacent plies. Heat-setting phenol-formaldehyde type glues are employed to form three-ply sheets. Cold-setting phenol-resorcinol type glues are employed to form the ultimate ply slab from pairs of three-ply sheets. Lumber of selected width is then ripped from the ply slabs.

摘要： A process for steam straightening and kiln drying lumber, the lumber being held under total restraint with respect to warping during the process. The lumber is steam straightened and kiln dried to a moisture content of nine percent using a cross-circulation air velocity of 1000 f.p.m. at dry and wet bulb temperatures of 240* F and 160* F for a first interval followed by a second interval at 195* F and 185* F. The lumber is cooled prior to being released from restraint.

摘要： THIS INVENTION RELATES TO A PROCESS FOR PRODUCING LAMINATED STRUCTURES, AND MORE SPECIFICALLY LAMINATED BEAMS, WHEREBY THE ENTIRE PRODUCT OF LOGS OR BOLTS OF WOOD IS UTILIZED, REGARDLESS OF THE PRESENCE OF UNDESIRABLE PROPERTIES INHERENT IN THE LUMBER CUT FROM SAID LOGS OR BOLTS. LAMINAE ARE OBTAINED FROM THE LOGS BY ANY CONVENIENT CUTTING METHOD, DRIED TO A LOW MOISTURE CONTENT, RELATIVELY GRADED ACCORDING TO THEIR DEFLECTION UNDER A STANDARD LOAD AT THEIR CENTER WHILE SUPPORTED NEAR THEIR END POINTS, THEN ARRANGED INTO A LAMINATED STRUCTURE WITH THOSE LAMINAE THAT HAVE THE GREATEST DEFLECTION IN THE CENTER OF THE STRUCTURE AND THOSE WITH PROGRESSIVELY LESS DEFLECTION LOCATED AWAY FROM THE CENTER SUCH THAT THE LEAST DEFLECTIVE LAMINAE ARE FURTHEST FROM THE CENTER OF THE STRUCTURE, AND THE LAMINAE ARE THEN BONDED BY AN ADHESIVE.
