Abstract

PURPOSE: To improve safety to the undulations of an undulating weir in a flexible film by mounting a plurality of undulating devices or means by means of different kinds of sensors and drive methods to the weir.
CONSTITUTION: A feed water pump 11 is actuated, and water is supplied into an enclosure 21. When the height of a weir reaches height (h) designed, rising is completed. When a water level of an upper current reaches an automatic undulating water-level 31, a motor sluice valve 1 is opened by means of detectors 13, 15, water in the enclosure 21 is discharged and the weir is undulated. Even when an electric automatic undulating device gets out of order, upper current water pushes up a float 16, compressed air in a compressed air tank 3 is communicated with a cylinder type butterfly valve 5, the valve is opened, water in the enclosure 21 is discharged and the weir is undulated. Even when said two devices are broken, the inner pressure of the enclosure reaches a top section of a siphon mechanism 18, and water in the enclosure 21 is discharged by means of the siphon mechanism 18. Even when sluice valves 1, 10 are opened, the water is discharged.
