    摘要: A web position detecting method and apparatus for a device which conveys a web floated with air streams jetted from air jetting holes. Pressure detecting units are positioned along both side edges of the web to detect the pressures of the air streams thereby to determine the position of the web in its widthwise direction by a difference of the pressures.
