In the article there are showed searches to increase the strength of plywood and curved laminated wood by modifying the proportion of glue. Source of plywood began in America. But without waterproof adhesive plywood use was limited. At that time used natural originating adhesives like albumin, casein etc. Nowadays in production of plywood and curved laminated wood there are used mostly two component glue on formaldehyde resin base. It opened a new possibility production of plywood Applied adhesive type significantly affects the physical properties of plywood. Today, plywood and veneer manufacturing curved instead use two component glue to formaldehyde resins. These adhesives have a short hardening time and high form stability There are few studies of different types of adhesive compound effect on the strength of plywood. The author describes an experiment where plywood samples are glued with urea-formaldehyde and polyvinyl acetate glue mixture. All samples used in 1.5 mm. husked thick birch plywood. There is also a test of physical and mechanical characteristics and determined the relative measurement error for each sample group, the comparison of actual test value of the critical, summarizing the results and conclusions are drawn.
