摘要： A combination of a thread carrying upper looper and a thread carrying lower looper which along with a thread carrying needle cooperate together in an overedge industrial sewing machine in which the thread carrying upper looper has its thread carrying groove located closer to the bottom edge of the blade face than to the upper edge of the blade face and has its point located above the thread carrying groove and is closer to the upper edge than to the lower edge. The blade of the thread carrying lower looper has a generally flat bottom surface having a 2.degree. rise starting 3/8" from its point and extending to the point.
