Definitions

  • the invention relates to a method by which the described under "prior art” serious disadvantages are eliminated; and that of the invention underlying procedure offers the solutions for optimal yield and the implementation of all important aspects for the physical area.
  • the invention meets the demand for optimal yield.
  • WET AREA are on the round timber outer segments (12) - after the previous one Surveying (R) - only three operations on one level (1/2/11) depending on the joint glue surfaces (1/2/3/4).
  • the individual cross-sectional height uses for the glue surface are retained in order then optimal in a further operation (and mostly different for right and left, s. 3 and 4) to use the actually possible log areas (13).
  • the procedure according to the invention also leads to that an advantageous tree ring structure (Fig. 3 and 10) is achieved (in referred to as "standing" with respect to the beam cross section H).
  • the maximum possible The effect is achieved with the first processing of the round timber outer segment (12) by the outer width machining applied to the upper joint surface machining (3 and 4) (1 and 2 with inclusion 11), making left and on the right independently of each other wood geometries are left, which then the creation of the processing areas in each case in the vicinity of the round timber outer areas (13) enable, and thereby the tree rings (Fig. 3 and 10) the trend after running in or out on two surfaces at right angles to each other and only lead to small parts of disadvantageous structures (15 a).
  • An essential point for the asymmetrical, complex use of the log cross-section (12) is the conversion of the measurement data into a accordingly aligned insertion position.
  • This is according to the invention solved that the reference point or the reference line (R) with 22 - 23 - 24 in accordance is to be brought; So a reference to the line that the important height use to 18/20 and 19/21 (Fig. 12).
  • the positions of the points 18/20 and 19/21 (Fig. 12) are derived from the permissible hole size, which in the DIBt approval is fixed at B 0.4 and H0.45.
  • the conical surfaces (32 and 33) are created with the high feed rates allowing circular saws only possible in connection with the inventive Circular saw alignments (35 - Fig. 13) including the deflection wedges (36).
  • EP 0 388 507 The procedures according to EP 0 388 507 are known and are practiced and EP 0 518 246, namely:
  • the currently practiced method leads to the symmetrical all-round machining in one of the two quarters (i.e. 50% of production) due to the lack of use of the outer tree rings (in the outer area of the logs - 13, p. also Fig. 3- right figure) the loss of favorable tree ring structures result, and thus the route of the unfavorable annual ring course (15 b) enlarged.
  • the wooden beam (16) with a central hole (17) is an absolute per se Quality product, but it is not with the currently known methods - or only with great restrictions - feasible.
  • Just three points from 0 388 507 and 0 518 246 have proven their worth, namely: core area-free beam corners / none Tree rings (eg "arched" on 7 or 8) tapering / and defined on only one surface Hole size with symmetrical processing and central separation.
  • MACHINING LINES (Fig. 11) are known in a wide variety of ways, but there is no MACHINING LINE with which 6 to 12 differently sized round timber outer segments per minute with the high feed rate of approx. 120 m / min necessary for 6 to 12 pieces. (high cutting performance due to loss of time due to alignment / START) would have to be processed without knocking out.
  • EP 0 518 246 discloses in a sketch processing in one machine run, but this is clearly shown as a PROCESSING CENTER with milling, planing or chipping heads that (in practice at high Feeds confirmed) branch tears to a degree cause the quarter pieces sometimes become unusable.
