ABSTRACT:
A process for collecting continuous polymer filaments centrifugally ejected from the spinning nozzles of a spinning head rotating at a high velocity is provided wherein the ejected filaments are caught by the surface of an annular form, flowing down liquid or by an annular wall surface wetted by a liquid flowing down thereon, spaced apart from and surrounding the spinning head and concentrically opposed to the head; then moved downwards from the location where the filaments are caught, by the flowing down liquid and if necessary, together with two or more guides; and dropped on a belt moving below the spinning head in the lateral direction and taken up in the form of multifilaments or dropped on the belt in the form of an ellipse long in the width direction of the belt and after adhering selvage materials to both the side end parts of the filaments, taken up in the form of a weft web of the ejected filaments.
