Handling of Assembly Materials in Furniture Manufacture

The three subjects discussed in this paper are the assembly of drawers, the application of adhesive, and the assembly of case goods involving a mortise and tenon joint. The drawer assembly found to be most satisfactory involves running the drawer sides through a double-end tenoner, then placing them in a hopper feed and, as they are discharged, passing them under a pressure feed glue spreader that applies glue exactly where needed. The front and then the back are locked to the sides by air pressure clamps. The use of the adhesive pressure gun provides accurate control over adhesive spread and eliminates adhesive waste. The drawbacks associated with normal mortise and tenon joints are overcome by using compressed mortises. These joints are considerably stronger. Case assembly using these joints can be accomplished without a “knockup” man. Other advantages include the elimination of nails, a longer tenon, and a stronger joint.
