Discussions and Studies on the Development of New Production System for Sugi Plywood.

现在，日本劳安胶合板产业已经开始出现问题。由于限制原木出口的规定和原木成本的上升，来自东南亚的热带木材供应正在减少。另一方面，国内木材资源逐渐增加。但这些资源包括小等级和低等级木材。有效利用这些资源非常重要，从而有助于日本林业的健康发展。以上述事实为背景，我们小组对如何实现日本胶合板产业进行了讨论和研究。综上所述，提出了杉木胶合板新的生产体系：(1)国内人工林原木的低档部分(主要是杉木原木)应作为低档原料使用。(2)单板和人造板生产过程应分离到原木生产区周围的地方工厂和大型人造板厂。(3)单板车床和单板烘干机的价格应非常低。它们的结构非常简单，但经久耐用。(4)单板加工设备可移动。应建立机器租赁制度。(5)人造板厂生产的单板产品应多样化。

Now, problems have begun to arise for the Japanese lauan plywood industry.The supply of tropical timbers from Southeast Asia is decreasing because of regulations restricting log exports and the rising costs of logs.On the other hand, domestic wood resources have increased gradually.However, these resources includes small and low grade timbers.It is very important to use these resources efficiently and thereby help to keep Japanese forestry in a sound condition.Thinking above mentioned facts for a background, our group discussed and studied how to realize sugi plywood industry.In conclusion, we are proposing the following new production system for sugi plywood.(1) The low-grade parts of domestic plantation log (mainly sugi log) should be used as low materials.(2) Veneer and panel production process should be separated into the local mills located around the log production area and the large scale panel factory.(3) The price of veneer lathe and veneer dryer should be very low.Their Structions are very simple but durable and practice.(4) Veneer processing installations are movable.Rental system of the machines should be established.(5) Sugi products made by panel factory should be divesified.
