ABSTRACT:
Apparatus for independently guiding two overlaid fabric workpieces as they are simultaneously fed through a sewing work station and are seamed together, wherein the guide apparatus comprises a pair of opposed guide wheels located upstream from the work station with respect to the direction of workpiece feed through the work station; separate servo motors for rotating guide wheels in planes perpendicular to the direction of workpiece feed; a separating bar for spacing apart the two workpieces and for individually pressing them against a different one of the guide wheels; and separate sensors for monitoring the edges of each workpiece and for controlling the servo motors separately to rotate their guide wheels so as to center each workpiece edge opposite its corresponding sensor.
