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