Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a web conveyance device conveying a thin film-shaped web such as a film or metallic foil so as not to generate meandering, skewing, creasing or wrinkle becoming problematic in conveyance and also conveying webs in a noncontact state, so as not to damage even a brittle surface web such as a functional film or flexible electronic device.SOLUTION: There is provided a web conveyance device 1 capable of conveying a web 10 except the end thereof in a noncontact state by supporting the web end. The device has a pair of crown rollers 11 in a face-to-face state on a straight line in the direction orthogonal to a web conveyance direction. The crown rollers are supported to be capable of conveying the web via a shaft 12.SELECTED DRAWING: Figure 1 【課題】フィルムや金属はくといった薄い膜状のウェブの搬送で問題となる蛇行や斜行、折れや皺などが発生しないように搬送するとともに、機能性フィルムやフレキシブル電子デバイスのような表面がもろいウェブに対しても傷つけないように非接触搬送を行うウェブ搬送装置を提供する。【解決手段】ウェブ１０の端部を支持することによりウェブの端部以外を非接触で搬送可能なウェブ搬送装置１であって、ウェブの搬送方向に直交する方向の一直線上に、互いに向い合わせにして一対のクラウンローラ１１を備えており、それらのクラウンローラは、それぞれシャフト１２を介して、ウェブを搬送可能に支持されていることを特徴とするウェブ搬送装置。【選択図】図１
