Abstract
A method of making lap seams by providing a constant overlap of the cut edge portions of two pieces of material to be joined together by a seam, stabilizing the overlapping material to prevent relative movement therebetween, rotating the overlapping material causing each piece of material to fold over the cut edge of the other piece of material to form the lap seam, and providing a double row of stitches each extending along a different one of the folded edges of the seam.
