METHOD OF PRODUCTION OF END BLOCKS FOR PARQUET Russian patent published in 2016 - IPC B27M3/04 B27K3/34 

FIELD: woodworking industry.

SUBSTANCE: timber, which is a waste of cleaning cutting or target timber, is cut using woodworking equipment to end or longitudinal workpieces. Using the mill the outer contour of the workpieces is imparted with a shape. Subsequently, the workpieces are fed to the impregnation bath with a solution of 30-50% concentration in acetone of low molecular weight polymer in the form of epoxy resin having a molecular weight of 600-1500 and containing the hardener as 10 wt % of hexamethylenediamine per 100 wt % of resin. After impregnation for 0.5-1.5 hours the workpieces are dried in a heat chamber at a temperature of 100-120°C for 1-3 hours until complete removal of volatile components.

EFFECT: increased physical and mechanical properties of the workpieces.
