Abstract
A yarn feed mechanism in which a counterlever frame extends forwardly from the tufting machine has high speed and low speed drive shafts driven, in synchronization, with the needle bar. Transversely aligned pairs of yarn feed rolls are suspended from the frame below each shaft and are driven through chains and sprockets from their associated drive shafts when the individual clutches of the rolls are energized. The rolls of transversely aligned pairs of rolls are spaced from each other with no intervening shaft so that intermediate portions of yarns extending between a coil and the rollers can be installed partially around the selected rolls without breaking or removing the yarns from the needles.
