This document discloses a joint system comprising first and second members (1, 2) formed of wood or wood based material. The members are joined in an end-to-end relationship along a longitudinal direction (L) by means of a finger joint (3). An end portion of the first member (1) presents a plurality of parallel straight finger-like projections (31), which enter and engage a plurality of complementary parallel straight notches (32) provided between projections (31) on the second member. A plane (Pt) comprising substantially the entire length of each projection tip (312), and/or a plane (Pn) comprising substantially the entire length of each notch bottom (321), extends at an angle (a) other than a right angle to the longitudinal direction (L). |
