Abstract

A predetermined length of yarn is clamped at one end and is fed across the upper side of an annular support, and a hook passes through the support and withdraws a loop of yarn through the support and supplies it to a guide moving around a circular track. As the guide passes around the track the size of the loop increases and the free end of the yarn is passed firstly through the support and then through the guide so that the yarn is laid out on the track. A push rod then pushes the yarn across the upper side of the support and the cycle repeated until all of the yarn has been wound around the support.
