A thread inserting device includes a guide pin having a thread capture portion at its tip for capturing a thread; a holder that fixedly holds the guide pin; a main body (first and second main bodies) slidably mounting the holder; and a thread cutting portion provided to the main body for cutting the thread to a length equal to or smaller than the protrusion of the thread capture portion from a thread captured position on a thread tip 6a side after the thread is captured by the thread capture portion. By shifting the holder, the thread capture portion is protruded to a predetermined length from the main body, and the thread cut to a predetermined length by the thread cutting portion is inserted into the thread inserting hole.

A sewing machine with a threading and air supply selecting device includes a base with a main shaft for driving at least one thread wiper, and a guiding pipe is provided on the thread wiper. On the base is further disposed an air supply device driven by a drive force source. Between the air supply source and he guiding pipe is disposed a pipe-moving device for moving the connecting pipe to the guiding pipe. A swing arm of a connecting rod assembly serves to control ON and Off of the air supply source. A directional positioning device is used to stop the main shaft from rotation, when the air supply source is working.

A device for assisting with threading an eyed needle with the eye being of a type peripherally delimited by a rim extending substantially in a plane includes a solid body forming an eye receiving portion designed to receive the eye of the needle and to keep the needle in position in relation to the solid body. A passage in the solid body includes a guide portion that forms a first funnel for guiding the hook to bring the hook out of a retracted position and into a threading position. The guide portion also forms a second funnel for returning the hook to the retracted position from the threading position. Each time the hook transitions from and back to the retracted position, the hook moves through the eye of the needle, drawing the thread through the eye when the hook returns to the retracted position from the threading position.
