ABSTRACT The present invention relates to circular knitting machines of the type used for making deep pile fabric. Particularly in such knitting machines where the knitting of multi-color fabric patterns is involved, a plurality of fiber feeding stations may preceed each individual yarn feeding station. The operating sequence of the machine can result in the development of loose or stray fibers in and around the cylinder circumference. Sufficient stray fiber can cause a gradual build-up and collection of such stray fibrous material as slugs or fiber balls upon the leading or front edges of the respective individual latch guards. Eventually, the mass or wad of fiber breaks away from the latch guard, and becomes engaged with the needles (and sinkers) operating in a fiber feeding station or in a yarn feeding station. The fiber ball becomes captured by one or more needles, and Is knitted into the fabric being produced. The present invention provides an improved latch guard for a circular knitting machine. This latch guard employs a deflector means which projects forwardly from the forward tip region thereof (relative to the direction of rotation of the needle carrying rotating cylinder). The deflector means is preferably characterized in that the radial distance there- along at successive locations measured from the axis of the cylinder continuously increases towards the forward end portion of the deflector means.
