摘要
A yarn feed system, for control of the feeding of one or more yarns to the needles of a tufting machine, which can be manufactured as a substantially standardized unit or attachment removably mounted to a tufting machine includes a series of yarn feed devices each having a drive motor with a replaceable yarn feed roll drive system mounted thereto. Each yarn feed roll drive system can include a set or series of yarn feed rolls mounted within a housing and having a series of gear teeth formed thereabout, with the gear teeth of the yarn feed rolls engaged in an intermeshing arrangement so that as one of the yarn feed rolls is driven by the drive motor, the other yarn feed rolls likewise are actively driven thereby. Each of the yarn feed rolls further will include a textured roll surface that can provide for enhanced grip and control of the feeding of the yarns which are extended thereabout to the needles of the tufting machine in accordance with a tufted pattern being formed.
