Machines for assembling knitted panties or stockings provided with means for sewing and other operations (e.g. turning the material inside-out, trimming the seam edges) are classified in the field where the alleged invention lies. A combined sewing machine with a turning inside-out mechanism where the invention lies in the turning inside-out of the material is classified in D06G 3/00 only. A combined sewing machine with trimming of the hosiery or seamed edges where the invention lies in the trimming is classified in D06C 13/12 only.

Sewing units consisting of combinations of several sewing machines which can be mounted in series or in parallel, incorporating e.g. conveying devices and devices not incorporated in the sewing machines for supplying and removing the work.

Machines provided with means for sewing and other operations (e.g. turning the material inside-out) are classified in the field where the alleged invention lies. A combined sewing machine with a turning inside-out mechanism where the invention lies in the turning inside-out of the material is classified in D06G 3/00 only.
