Claims

[Claims for Utility Model Registration] (1) In a measuring device for controlling the width of an inflation tube extruded from an extruder, an exhaust supply for sending or extracting air into the inflation tube. An air supply device is provided on a turntable installed at the extrusion port on the extruder side, and a control panel for controlling the exhaust air supply device is provided on the intake side of the inflation tube, and communication between these devices is conducted wirelessly. A device for measuring the width of an inflation tube, characterized in that it is configured to be measured over a line. (2) A slip ring for this circuit is further provided in the slip ring provided on the turntable instead of the radio line, and the signal from the control panel is transmitted by this slip ring. An inflation tube width measuring device as set forth in claim (1) of the utility model registration.
