DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a collected lumber capable of performing an effective utilization of thinned-out woods with a small diameter or a short length and scrap material cut and removed during a growing stage of Sugi (Cryptmeria japonica D. Don), Japanese cypress and the like, a process for producing the collected lumber and, more particularly, to a collected lumber and a process for producing the collected lumber of inexpensive cost which can be used in a wide range of building materials, can shorten an aging period of the collected lumber after the woods are collected, and further improve its productivity.
In addition, the present invention relates to a process for producing collected lumbers or the like having various shapes such as a curved shape, a linear shape and the like in which they can be collected from each other into a predetermined shape without being influenced by each of the shapes and without producing any gaps between each of the thinned-out woods.
In addition, the present invention relates to a collected lumber having a high strength which can be used in a wide range of building materials and has a low cost, and to a process for producing the collected lumber.
Further, the present invention relates to wood building materials with fine straight grain and of low cost which can be highly valued as floor material, wall material or the like, and to a process for producing the wood building materials.
Still further, the present invention relates to a collected lumber of low cost, capable of maintaining the annual rings stored in each of the thinned-out woods at an end surface of the collected lumber while being molded into various shapes, realizing a specific effect in design, being used in various wide ranges of applications and concurrently applying various superior characteristics of the collected lumber after collecting the woods to each of the applications and thus improving its productivity by shortening the aging period.
In addition, the present invention relates to woods, bamboos and their collected lumbers in which the annual rings in each of the thinned-out woods can be left at the end of the collected lumbers while being molded, whereby a specific design effect can be realized, a surface with high hardness and high abrasion resistance can be attained and they can be applied over various wide ranges.
Additionally, the present invention relates to a device for producing a collected lumber capable of performing an effective utilization of thinned-out wood of small diameter or short length material and scrap material removed during a growing step of Sugi (Cryptmeria japonica D.Don) or Japanese cypress or the like and, more particularly, to a vehicle-carried type apparatus for manufacturing a collected lumber which can move up to a producing center of wood at a destination of carrying out of the thinned-out wood, produce the collected lumber from the thinned-out woods at the destination of carrying out so as to ship the collected lumber.
DESCRIPTION OF THE PRIOR ART
cypress or the like are frequently utilized as building materials, they are inherently soft materials to show a low rigidity, whereby their applicable range has been limited by themselves. In particular, thinned-out woods removed during a growing step of Sugi (Cryptmeria japonica D. Don) or Japanese cypress or the like were of small diameter, and additionally, they were frequently soft and curved, so that such thinned-out woods could hardly be used as building materials, for example, pillars or the like.
In order to perform the effective utilization of such thinned-out woods, various processes have been proposed in the prior art. For example, in Japanese Patent Laid-Open No. Hei 3-231802 is disclosed a process for improving a quality of wood by a process wherein the woods are spread within water vapor and softened, thereafter they are compressively molded under a condition of high pressure and the molding of the woods is fixed. In addition, Japanese Patent Laid-Open No. Hei 3-97503 provides a desc
