Yarn Feed Roller Assembly ABSTRACT OF THE DISCLOSURE A yarn feed roller assembly for tufting machine pattern attachments for controlling the amount of yarn supplied to the needles of the tufting machine in accordance with a pattern. The assembly includes a plurality of parallel modules each of which comprises a housing mounting a shaft on which a plurality of clutch members and respective drive members are mounted within the housing. A yarn feed roller is secured to one end of the shaft which extends outside the module housing. Means are provided to drive each drive member of the module at a different speed, corresponding drive members of all the modules being drivingly connected to one another. The clutches are selectively energized to transmit the speed of a selected drive member to the shaft and thereby to the roller. All the module housings are mounted in cantilevered fashion on a frame and each may be individually readily removed for maintenance.
