ABSTRACT:
A linking machine having a rotatable dial mounting a plurality of radially extending points on which two contiguous fabrics to be joined together are impaled. The sewing linking is provided with at least two needles, with one or more needles operating from opposite sides of the fabrics. One or more needles are located exteriorly of the dial, and each cooperates with a thread guide located interiorly of the dial to form a thread into a chain of stitches. One or more needles are located interiorly of the dial, and each cooperates with a thread guide located exteriorly of the dial to form a thread into a separate chain of stitches. In one form of the invention, the machine has a pair of reciprocal linking needles disposed on opposite sides of the fabrics to be joined, and each needle forms a simple single thread stitch chain. In another form of the invention, a pair of oversew needles also are provided, each of which enters the fabrics and withdraws, and then passes over the edges of the fabrics and withdraws, to form an oversew stitch to lock the free edges of the fabrics into the seam. In such an arrangement, a fabric cutter may be utilized to remove excess fabric after formation of the two single chain stitches and prior to the formation of the oversew stitch.
