Abstract
An individual yarn clamping and cutting device is provided for each yarn guide and is moved to an open position in response to movement of the yarn guide from active to inactive position. The yarn clamping and cutting devices are moved to a closed position by cam means carried by the rotating needle cylinder. A yarn guide shifting cam is provided for imparting a slight amount of downward movement to the yarn guides to shift the same from a first upper active position to a second slightly lower active yarn feeding position during introduction of the yarn to reduce the tension in the yarn as the needles begin to knit and to aid in preventing yarn breakage. The yarn guides are mounted to facilitate individual threading of the yarn guides and are mounted for outward tilting movement of their upper ends to a readily accessible threading position while the remaining yarn guides remain in the normal operating position.
