Effect of solvent extraction and planing of veneers from Southeast Asian species upon glueline characteristics and bond durability

Creator:

Dougal, Edward Francis

Abstract:

Using Southeast Asian hardwood veneers for exterior plywood siding has caused problems because some species produced quality plywood while other species produced plywood which delaminated soon after being put in service in exterior exposure. This study attempted to improve the durability of glue bonds of some Southeast Asian hardwood veneers...

Heat conditioning of veneer blocks

Creator:

Resch, Helmuth, Parker, R., and Oregon State University. Forest Research Laboratory

Abstract:

Short-term heating of softwood veneer blocks temporarily softens the wood so that it can be peeled more readily. Heating reduces the depth of lathe checks and the likelihood of splitting and thereby increases the quality and quantity of veneer recovered. The softwood-plywood industry conventionally conditions blocks three ways: steaming blocks...

The economic feasibility of preheating Douglas-fir blocks prior to peeling

Creator:

Baskin, Richard

Abstract:

Past research and industrial sources have implied that preheating Douglas-fir Pseudotsuga menziesii (Mirb.) Franco prior to peeling veneer was economically feasible. To test this, the effect of treatment temperature on veneer yield and thickness variation for three diameter classes of low grade Douglas-fir logs was studied and related to the...
