Abstract

1,049,757. Jointing timber. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept.23, 1964 [Sept. 26, 19631, No.38039/63. Heading A4H. In a method of finger jointing timber and like material the ends of the timber are first heated in the region in which the impressed grooves are to be formed and the heated regions are then forced against a cooled die to form complementary serrations. The two pieces of timber 11, 12 are held on tables 13, 16 by clamps 14, 17 operated by air cylinders 15, 18 or other means, the tables are slid together on links 21 by an air cylinder 22 and the timber ends heated by high frequency heating or other means. The ends are now separated and a water cooled die 27 placed between them and the tables 13, 16 moved together again to bring the ends of the timber into abutment with the die under a pressure of 2,800 pounds per square inch to form the serrations. After a short interval the ends are again separated and coated with glue, abutted under a lower pressure of the order of 300 pounds per square inch and the high frequency electrodes brought again into place to cure the adhesive by heating.
