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

现在，日本lauan胶合板行业开始出现问题。由于限制原木出口的法规和原木成本的上升，东南亚热带木材的供应正在减少。另一方面，国内木材资源逐渐增加。然而，这些资源包括小和低等级的木材。有效地利用这些资源，从而帮助日本林业保持良好的状态是非常重要的。以上述事实为背景，我们小组对如何实现杉木胶合板产业进行了探讨和研究。总之，我们建议以下杉木胶合板的新生产系统。(1)国产人工林原木（主要是杉木原木）的低档部分应选用低档材料。(2)贴面和面板的生产过程应分为位于原木生产区周围的当地工厂和大型面板工厂。(3)单板车床和单板干燥机的价格应该很低。它们的操作方法非常简单，但经久耐用。(4)单板加工装置是可移动的。建立机器租赁制度。(5)面板厂生产的Sugi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.
