Definitions

  • the invention relates to the method according to the introductory part of patent claim 1 for manufacturing a timber log.
  • a drawback with the known method is its slowness.
  • Another problem is the drying.
  • the heart of a massive log dries remarkably slower than the surface part.
  • the drying In order to prevent the wood from splitting, the drying must be realized in a slow and controlled fashion, so that the inside of the log dries at the same pace as the surface.
  • the object of the present invention is to introduce a new method for manufacturing a log, owing to which method a log can be manufactured in a remarkably quicker fashion than before.
  • the method of the invention for manufacturing a log is characterized by the novel features enlisted in the independent patent claim.
  • a narrow and long groove here means a groove where the width-length ratio is for instance 1 : 100 or less. This kind of groove is made in the timber blank by means of a circular saw or a similar tool.
  • a deep groove here means a groove where the width-depth ratio is for instance 1: 10 or less.
  • the grooves are arranged to extend in the vertical direction as far as the middle section of the timber blank. It is also possible that the grooves extend throughout the whole timber blank.
  • Another advantage of the invention is that the timber blank does not split when drying like a massive timber blank does.
  • a particularly important factor with a timber blank and a log is that the vertical sides remain essentially unbroken and unsplit on the surface. This requirement set for the log is effectively realized by applying the present invention. Hence the quality of the timber blank and the log worked thereof is improved.
  • the timber blank keeps well in measure and remains straight at the drying stage, it does not bend and twist as easily as a corresponding massive whole wood timber blank.
  • the quality of the timber blank and the final log is improved in this respect, too.
  • a particularly advantageous feature from the point of view of the invention is to arrange the grooves in the timber blank (and further in the final log worked therefrom) in a symmetrical fashion. Now the possible twists and/or tendencies to bend owing to asymmetric working of the timber blank can be eliminated.
  • the grooves are made in the timber blank so that they are not outwardly visible in a ready-made log when the logs are stacked for instance when building a wall or another similar construction.
  • the grooves are arranged in the timber blank and in the log from either the bottom and/or top surfaces towards the heart, in which case the stacked logs cover the groove apertures.
  • the natural good qualities of timber such as a breathing composition and a pleasant appearance, are maintained.
  • a surprising advantage of the invention is the fact that the heat insulation capacity of the log manufactured of a timber blank is improved.
  • the narrow grooves and advantageously the large number of parallel grooves, for instance six or more, effectively prevent heat from conducting in between the inner and outer surfaces of the log, and as a consequence the heat insulation capacity of this kind of log is clearly better than those of a massive whole wood log of the same size.
  • the grooves are narrow, advantageously with a niinimum width of 5 mm, and relatively long, advantageously with a maximum length of 600-1,200 mm, in the lengthwise direction of the timber blank and the log. It is fairly simple to provide such grooves in the log; they can be sawn with a circular saw or a corresponding tool, for example adjacent grooves at the same time. Thus the creation of the grooves in the timber blank is a relatively simple and quick operation.
  • FIGS. la and lb are schematic illustrations of a log of wood and of a timber blank worked thereof, seen in perspective;

  • Figures la and lb show a log 1; la, lb, and the working plans drawn at the end thereof.
  • the log of wood 1; la should be sawn into a timber blank 2; 2a which is quadrangular in cross-section and has a predetermined width 1 and height k.
  • the width 1 and height k of the timber blank essentially correspond to the width and height of the planed log to be manufactured, but provisions for drying and working loss are taken into account in the measures.
  • the log of wood 1; lb is meant to be turned into a round timber blank 2; 2a, circular in cross-section; the diameter d of the said timber blank essentially corresponds to the diameter of the round log manufactured of the log 1, when provisions for drying and working are taken into account.
  • the conical shape of the original log is eliminated by working the log into an essentially cylindrical timber blank.
  • the log which is most advantageously peeled, can also be considered as a timber blank, particularly the blank of a round log.

  • the groove system is based on the idea that the timber blank 2; 2a, 2b is thought as divided, in the transversal direction, into parallel groove zones 5; 5a, 5b, wherebetween there are left wood material zones 6; 6a, 6b. Both zones 5, 6, alternating in the transversal direction, are defined to be in cross-section at least roughly quadrangular areas which extend in the lengthwise direction of the timber blank from one end to another.

  • the parallel grooves 4 are arranged in the cross-section plane of the timber blank in the vertical middle area 7; 7a, 7b thereof, most advantageously in a symmetrical fashion (in the middle of the timber blank, with respect to an imaginary vertical axis and the vertical plane passing therethrough).
  • each groove zone 5; 5a, 5b of the timber blank 2; 2a, 2b comprises one narrow and long groove 4; 4a, 4b, which extends from the surface of the timber blank to at least the middle area thereof.
  • the grooves 4; 4a, 4b belonging to the groove zones 5; 5a, 5b are arranged to extend, in the lengthwise direction of the timber blank, from the first end 23 a to the second end 23b thereof, so that they begin and end at a slight distance, at least, from the free ends of the timber blank 2; 2a, 2b.

  • the timber blanks 2; 2a, 2b are stacked to suitable drying piles in a drying carriage, whereafter they are put in a drying oven with a temperature of the order 40-60° C. When the moisture content of the timber blanks is reduced to for instance 15 %, they are removed from the oven.
  • the timber blank 2; 2a, 2b is not massive, uniform wood material anymore, but is divided into fairly thin wood material sections: to wood material zones 6; 6a, 6b and to side wood material layers 8; 9; 8a, 9a; 8b, 9b.
  • the timber blank 2; 2a, 2b can be dried nearly as quickly as a sawn wood piece of the same size as the side wood material layers 8, 9.
