Abstract
Abstract A thick-walled, three-dimensionally shaped fabric is produced on a circular weaving machine with the aid of a rotating filling yarn inserter. The filling yarn inserter is adaptable for placing a filling yarn in an annular shed formed by the machine by moving through a path circling the vertical axis of the fabric.
