Abstract: PURPOSE:To certainly wash a shutter member subjected to punching processing and to facilitate drain treatment after washing. CONSTITUTION:In a washing apparatus washing a continuously sent-out shutter member made of stainless steel, a guide rail 3 guiding and holding the transferred shutter member in a predetermined direction and a plurality of washing nozzles 23 spraying a washing soln. on the shutter member are installed and a plurality of supply tanks 6a, 6b, 6c supplying a washing soln. to the washing nozzles are arranged along the guide rail and a flow line allowing the washing soln. overflowing the supply tanks to successively flow in the supply tanks on the upstream side of the rail is formed. Further, the recovery line recoving the washing soln. from the upstream supply tanks is formed and a separation device separating and removing the matter to be washed off bonded to the shutter member from the washing soln. of the recovery line is installed and, further, connection lines connecting the separation device and the downstream supply tanks are formed.

Abstract: PURPOSE:To enable gentle cleaning to the global environment by immersing a metallic shutter into a prescribed aq. soln. and irradiating the shutter with ultrasonic waves at the time of cleaning the shutter. CONSTITUTION:The metallic shutter for floppy disks is immersed into the aq. soln. contg. sodium hydroxide NaOH and sodium gluoconate G-Na and is irradiated with the ultrasonic waves at the time of cleaning the shutter. The total content of the NaOH and the G-Na is specified to 1 to 10wt.% and the content of the NaOH is set the same as or higher than the content of the G-Na in the aq. soln.. The frequency of the ultrasonic waves is set at 28 to 50KHz in the irradiation with the ultrasonic waves. The metallic shutter is formed by inserting a metallic plate 2 drawn out of a roll 1 of a prescribed width between a lower mold 3a fixed to a press machine 3 and a vertically moving upper mold 3b. The plate is blanked by a tool provided in the mold 3b and is bent, by which the shutter is completed. Since trichloroethane is not used at the time of washing, the cleaning of the shutter friendly to the global environment is executed.
