ABSTRACT:
The present invention provides a double end yarn drive pattern attachment for tufting machines characterized by independent servo-motor control of yarn feed rolls capable of increased torque to carry multiple yarn ends on a single feed roll, thereby economically retaining many advantages of a single end pattern attachment. The improved attachment utilizes an intermediate gear to provide a relatively high torque drive adaptable between single and plural yarn pattern attachments.
