METHOD OF MAKING GROOVES ON ENDS OF WOOD SHEET MATERIALS Russian patent published in 2013 - IPC B27D1/10 B27N3/18

Abstract RU 2478036 C2

FIELD: process engineering.

SUBSTANCE: invention relates to jointing the ends of wood sheet materials, particularly, to making mate grooves at said ends. Proposed method comprises, at least, driving the groove at end of said sheet material by rotary cutting tool. Note here that warped section of said end is leveled by clamping plate. This allows avoiding deep cutting and ensures equal size and shape grooves.

EFFECT: higher strength and reliability of joint.
