Described is a mill for stretching a web of fibrous material, in which the lower input roller (1) is made of steel and has a smooth, entirely cylindrical surface. This significantly improves the quality of the yarn and avoids to a large extent the occurrence of periodic defects in the yarn. The uniformity of the yarn produced by a stretching mill of this kind is significantly improved compared with yarn produced by a conventional stretching mill. |
