A method of making a joint between first and second rigid members (31, 32) is described, said first member (31) having at least a first elongate flexible sealing material (35) and said second member (32) having at least a second corresponding elongate sealing material (36), comprising the steps of: 1) providing said first and second members each having an exposed surface, the exposed surface of said first member including a section through said first sealing material and the exposed surface of said second member including a section through said second sealing material without removing a substantial part of either the first or second members in the region of the joint; 2) locating each member so that the exposed surface of the first member faces and is separated from the exposed surface of said second member; 3) raising the temperature of thermoplastic material which is to form the joint between the members so that the thermoplastic material enters its plastic phase; 4) translating at least one of the first and second members so that the exposed surfaces are brought into contact and the thermoplastic material forms the joint between said first and second members and the joint between said first and second sealing materials; and 5) during said translating step: providing bead control (47, 48) for at least the outer surface of said first and second sealing materials. An apparatus for carrying out the method is described. A frame made with the method has excellent sealing properties in the corners. <IMAGE> |
