Abstract
A linking machine is provided having a plurality of extending points onto which pieces of fabric to be joined are threaded. The linking machine consists of a linking station, a cutting station, and an over-sew station. The linking station has one needle and may have a pair of needles which operate to link pieces of fabric together by a single thread chain stitch, thereafter, the fabric which has heretofore been threaded on points of the dial is presented to a cutter at the cutting station which removes surplus fabric on the exposed fabric side of the linking thread whereupon the fabric remaining on the points is presented to the over-sew station having a needle which pierces the fabric then withdraws then returns over the edge of the fabric, each time being wrapped with the thread by thread guides whereupon an over-sew stitch over the edge of the fabric is formed. In an alternative embodiment, the linking machine may have a pair of over-sew needles, wherein the second needle forms an over-sew over the stitch formed by the first needle which securely locks the first over-sew thread.
