Abstract
A plating feeder for use in a circular knitting machine comprises a first mouth for supplying a first yarn, and a second mouth for supplying a second yarn and which is movable relative to the first and second mouths together to alter the angle between the yarns fed by the plating feeder during knitting. The first mouth is provided on an elongate first feeder part and the second mouth is provided on a second feeder part slidable lengthwise on the first feeder part. A biasing spring urges the first and second mouths together and a cam follower coacts with the movable mouth and engages with a cam to override the spring. The first mouth is in a form of a narrow aperture for defining a single yarn feed position for a facing yarn and the second mouth is in a form of a trough at least partly surrounding the first mouth for defining alternative, interconnected yarn feed positions for a backing yarn on either side of the first mouth.
