PURPOSE:To efficiently manufacture an Ni powder dry type sheet having good thickness accuracy at a low cost by spreading Ni powder on upper surface of a heat resistant plate, measuring the upper surface level after removing the excess Ni powder with a plane cutter to control the thickness. CONSTITUTION:A table 2 arranging the heat resistant plate 7 on the upper face is shifted on a bad 1 through nut 3, feeding screw 4, driving motor 5, etc. At first, in an Ni powder spreading unit 10, the Ni powder 8 is spread on the upper surface of heat resistant plate 7. Successively, in a sheet manufacturing unit 11, the excess Ni powder 8 is scooped up from the upper surface of heat resistant Ni powder 8 is scooped up from the upper surface of heat resistant plate 7 with the plane cutter 13 or bland cleanly finished so that the Ni powder does not stick, and removed through a collect nozzle 14 to finish this to the dry type sheet 9 having the fixed thickness. Successively, in a sheet thickness measuring unit 12, the upper surface level of the above sheet 9 is measured with a non-contacting laser beam displacement gage 15 through a scanner 16. Thickness of the dry sheet 9 is obtd. from difference between this measured value and the upper surface level of heat resistant plate 7 pre- measured and stored to execute manufacturing control. |
