摘要： An improved sewing machine, for sewing overlapping materials and making ornamental seams on a single material comprises: a first supplying assembly for supplying a first seaming yarn, arranged under the pieces to be seamed, a second supplying assembly for supplying a second seaming yarn, arranged above the pieces to be seamed, a needle arranged on the top of the seaming region and a needle driving device for driving the needle by a reciprocating movement along a movement axis thereof in order to cause the needle tip to pass through the pieces to be seamed and to engage the first yarn so as to provide a yarn loop traversed by the second yarn, as a seaming stitch is formed. The machine has the main feature that it further comprises a loading device for automatically loading the second yarn, inside a "crochet" of the assembly supplying the second yarn, as well as a cutting device for cutting the second yarn at the end of the second yarn loading operation.
