| 摘要 |
The invention relates to a method wherein a cleaning solution, such as caustic soda, is guided through an inner passage of the needles (40), pressurised air is injected into said needles, and pressurised air is then guided through the inside of the needles. The machine comprises upper and lower compartments (2, 3) separated by a tray (6), and a tank (4) for the cleaning solution. The tray (6) supports the needles (40) to be cleaned, with a lower part of said needles being received inside containers (17) wherein said needles (40) receive said cleaning solution driven by a pump (29), the pressurised air (23) and the washing water (25), via conduits (19, 21, 23, 25, 27) provided with valves (20, 24, 26, 28) communicating with the containers (17). The tray (6) collects the fluids that come out of the upper holes of the needles (40). |
