Abstract:
Upper and lower loopers 2 and 3 are annular loopers. A pump 4 for supplying pressurized air is connected to thread introduction portions 7, which are connected to thread inlets of the loopers through annular conduits 5 and 6 and conduits 5' and 6'. The conduits 5' and 6' are slidable relatively to the conduits 5 and 6, and are connected to thread inlets of the loopers in the threading operation. In this state, the pressurized air is supplied from the pump 4 to the thread introduction portion 7, whereby the thread is transferred by the flow of the air and is fed to an outlet of the annular looper. A connecting portion moving plate 10 for connecting the conduits 5' and 6' is positioned in a disengaged position during the operation of the sewing machine by a stopper 18 and is positioned in an engaged position during a threading operation.
