PURPOSE:To continuously supply air without leakage of air by disposing along a main line a loop-like air hose with a path moving synchronously with the main line, which is provided with air supply units mounted at equal intervals. CONSTITUTION:When air supply units 7, 8 reach a position (i), a holder 29 is raised by action of the second cam surface 34 to clamp the units 7, 8. At this time, air is transported through a hose 21, a rotary joint 20, an air path 19 and a vinyl tube 26 to a supply coupler 25. When the units reach a position (ii), a limit valve is turned on by action of the first cam surface 33 to supply air in the tube 26 through a branch pipe 28 to a cylinder device 24, which results in lowering the supply coupler 25 to be connected to a receiver coupler 13, so that air is supplied to a hose 9. |
