Finger joint plate (board), also known as a comb joint, is a woodworking joint made by cutting a set of complementary, interlocking profiles in two pieces of wood, which are then glued. The cross-section of the joint resembles the interlocking of fingers between two hands, hence the name “Finger joint”. The sides of each profile increase the surface area for gluing, resulting in a strong bond, stronger than a butt joint but not very visually appealing.
Here we will talk about the manufacture of finger joint board today.
6 steps are basic in manufacturing finger-jointed wood products:
Step 1: Selection and preparation of material
Step 2: Measuring finger Joints and cutouts, cutting the finger joints
Step 3: Formation of a joint profile
There are 3 types of connection methods base on the orientation of finger joints, vertical, horizontal and inclined.
Step 4: Application of adhesive
Finger-jointed plate/board glue process:
End-glued: short lengths are finger-jointed and end-glued only;
End-and edge-glued: Panels made up of random width finger-jointed stock glued edge to edge;
Edge-glued: Panels made of full-length strips glued edge to edge.
Step 5: Assembly of joint,
