ROLLER FOR TRANSPORTING HOLLOW FILAMENTS, MANUFACTURING METHOD FOR HOLLOW FILAMENTS, AND MANUFACTURING METHOD AND MANUFACTURING DEVICE FOR HOLLOW FILAMENT MEMBRANE SHEETS

摘要

In the present invention, in order to alleviate the fluctuation of the tension applied to the hollow filament, a new roll or device other than the existing roll or device is not added to the apodo, The hollow filament conveying roll capable of alleviating the fluctuation of the tension applied to the hollow filaments for each hollow filament. Is a transport roll 1010 for simultaneously transporting two or more hollow filament products F. The transport roll 1010 has a roll body 1014 and a plurality of filaments F (Tension fluctuation easing means) for relieving the fluctuation and the convex forming members 1016 are provided at two or more places on the outer circumferential surface of the roll body 1014 at intervals in the circumferential direction. Further, the present invention is a method for producing a hollow filament water sheet shaped article, which comprises a connecting step, a winding step, a fixing step, and a cutting step, and at least one roll used in the step is a roll having the tension fluctuation mitigation means to provide.
