ABSTRACT:
An apparatus in combination with a sewing machine having a stitch-former that utilizes thread, alternately engageable and disengageable with a garment having portions of different thickness material, and a feeder for feeding the garment through the stitch-former when the stitch-former is disengaged from the garment, comprises a puller roller, a feed rocker shaft, first and second presser feet and first and second pneumatic cylinders. The puller roller is positioned downstream of the feeder for uniformly pulling the garment when the stitch-former is disengaged from the garment. The feed rocker shaft is clampingly-attached to the feeder for driving the puller roller in synchronization with the stitch-former. The feed rocker shaft intermittently engages the puller roller when the stitch-former is disengaged from the garment and intermittently disengages the puller roller when the stitch-former is engaged with the garment. The first and second presser feet are positioned adjacent the puller roller for urging the garment against the puller roller. The first and second pneumatic cylinders are operatively connected to the first and second presser feet, respectively, for selectively and independently moving the first and second presser feet into and out of engagement with the portions of different thickness material of the garment.
