Innovative designs of wood products plating in jointless gluing

Abstract

The paper discusses the features of design and technology of finger joints in the manufacture of frame-paneled platings of doors and furniture fronts. At the design stage we solve two problems: a) the choice of shapes and sizes of studs and grooves according to GOST R 9330, b) calculation of probabilistic values of the maximum deviations of landings with interference by GOST 6449. It was proposed to abandon the finger joints, restrict ourselves to assembly in tongue and groove, so with conjugation in counterprofiles groove is milled on the ends the horizontal bars after pre-pruning to eliminate chipping and tongue - on inner shared edge of vertical bars.
