Abstract
A tufting machine has a yarn feed pattern assembly including a housing having a mounting plate for mounting a multiplicity of yarn feed rollers from the exterior of said mounting plate and a multiplicity of servo motors connected to said mounting plate on the interior of said housing. Each servo motor is connected to a respective feed roller. A multiplicity of tubes extend within said housing, half the tubes directing yarn from a source to respective rollers and half of the tubes directing yarn from the rollers to respective needles. The guide tubes direct yarn from the interior of said housing through said mounting plate where the yarn is trained about a respective roller and directed back into the yarn guide leading toward the needles of said tufting machine.
