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.

现在，日本劳安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。然而，这些资源包括小木材和低等级木材。有效地利用这些资源，从而有助于保持日本林业的健康，这是非常重要的。以上述事实为背景，我们的小组讨论并研究了如何实现杉木胶合板产业。最后，我们提出了以下杉木胶合板的新生产系统。(1)国产种植园原木（主要是水杉）的低等级部分应作为低等级原料。(2)单板和板材的生产过程应分为位于原木生产区周围的当地米尔斯工厂和大型板材工厂。(3)旋切机和旋切干燥机价格低廉，结构简单，实用耐用。(4)单板加工设备可移动，应建立机器租赁制度。(5)由面板厂生产的杉产品应被剥离。
