ABSTRACT:
A sewing apparatus and method for receiving tubular knit fabric from a pre-knitted roll and making the fabric into foot covers. The fabric is first passed through an unique spreader which is mounted at the end of a pivotal boom adjacent a sewing machine. A gripping head advances to the spreader and grips the portion of the fabric held by the spreader. The gripping head than withdraws a predetermined length of fabric from the pre-knitted roll through the spreader. An air jet blows the free end of the length of tubular knit fabric into a vacuum take-off tube connected to a gathering box. The pivotal boom then swings toward the sewing machine. As the pivotal boom completes it swing, the tubular knit fabric is fed to the sewing machine which simultaneously sews the end immediately adjacent the spreader, cuts the free end from the pre-knitted roll, and gathers the finished product in the take-off tube. The pivotal boom then returns to its starting position and the cycle repeats, thereby forming a number of short, closed end lengths suitable as foot covers.
