Description
The main purpose of this nvestigation was to find the yield rate of the Lauan log(block) used for the plywood manufacture. The measurements were doun under the practical onditions. (Osaka, Tootori, Shimane district)
The Obtained results are shown in Fig. 1 , 2. From these results it is considered that the yield rate are as follows:
face Veneer 40-50 %
core 10 %
The relations between diameter of block and the rate are shown in Fig. 3.
The rate should be droped by the eccentricity of set (Rotary chuck and block center), and these tendencies colculated by a experimental formura VI are shown in Fig. 5.
