  • Patent number: 4273737
    Abstract: A method and an apparatus for manufacturing furniture by joining panels and making corners, in which at least two panels each having generally parallel generally planar major faces and a generally planar end surface bounding one edge of the major faces are arranged with mold instrumentalities to form a mold cavity bounded in part by the respective end surfaces of the two panels. Plastic material is deposited into the mold cavity and the two panels are bonded together into a corner configuration by the plastic material while the plastic material is confined and shaped into a predetermined configuration. The plastic material preferably is a structural foam material and the mold instrumentalities preferably define an inclined, heated mold cavity in which reactants may form the structural foam.
