Definitions

  • the present invention avoids this additional expense, by providing on what would otherwise be abutting surfaces of the boards, projections which have a low mechanical resistance to compression. During assembly of the boards, these projections space the boards apart at the proper mutual distance, but compress during expansion of the boards, thereby preventing buckling of the assembly of boards.
  • the projections are spaced apart and formed from a continuous rib of preferably triangular cross section, which has been formed on the bottom of the groove of each board.
  • the rib is formed by milling, the mill thus having peripheral V-shaped grooves if the rib is to be triangular.
  • the spacing of the projections is obtained by compressing the rib bv means of a disc which has at its periphery the contour of the groove without the rib, and which has spaced apart about its periphery a plurality of recesses whose peripheral extent is less than the spacing between the recesses, whereby the disc between the recesses compresses the rib to the level of the floor of the groove and leaves spaced projections at the locations of the recesses on the disc.
  • a hoard 1 of known type generally of deal, commonly called "match- board”
  • a groove 2 extending lengthwise thereof along one edge
  • a tongue 3 extending lengthwise thereof along the other edge of the board.
  • groove 2 is deepened by means of a mill (not shown) modified for this purpose so as to form on the bottom 2' of the groove a continuous rib 4 which is preferably of triangular cross section.
  • Rib 4 is then flattened at spaced intervals with the disc 5 shown in Fig. 4.
  • Disc 5 has peripheral cavities 6, 6', 6" but is otherwise of cylindrical cross-sectional configuration, these cavities being spaced apart by partcylindrical sections 5', 5" which serve to compress rib 4 along the lines 8', 8" shown in Fig. 3, so as to leave projections 4', 4", 4"' spaced apart from each other a distance greater than the length of the projections.
  • most of rib 4 has been flattened by disc 5.
  • the assembly of the boards is shown in Fig. 5.
  • the tongue 3 of one board penetrates into the groove 2 of the other until the edge 3' of the tongue comes into contact with projections 4', 4", etc. of the other board, the two boards 1 and 1' are automatically mutually spaced to provide a space 7 therebetween, that is, by a distance "d" which allows for expansion of the boards without causing buckling and without the need to une :separate spacers during assembly of the boards.
  • the projections 4', 4", etc. compress easily in view of their low mechanical resistance to compression, and space 7 closes.
  • the boards of the present invention can be not only of wood, but also of composites such as particle board or chip board or the like.
  • the projections 4', 4", etc. can be formed instead on edge 3' of tongue 3.
