Needle moves slightly upward to form a small loop in the upper thread at the needle's eye. 4 Shuttle is midway, and its point ('hook') has passed through the loop in the upper thread. Upper thread is now looped around the shuttle's waist. Needle is up. 5 Shuttle is forward again, having completely passed through the loop in the upper thread.
The thread tension mechanisms, one for the upper thread and one for the lower thread, prevent either thread from pulling the entwine point out of the middle of the material. Prior to the invention of the rotating hook, lockstitch machines placed the lower bobbin inside a miniature shuttle which would be passed through the loop formed when the ...
Tension of the bobbin thread is maintained with a bobbin case, a metal enclosure with a leaf spring which keeps the thread taut. The bobbin case has to be free-floating (not attached to an axle) in order to allow the top thread to pass around the bobbin completely and hook the bobbin thread. Bobbins vary in shape and size, depending on the ...
The rotary hook or rotating hook is a bobbin driver design used in lockstitch sewing machines since the 19th century. It triumphed over competing designs because it can run at higher speeds with less vibration. Rotary hooks and oscillating shuttles are the two most common bobbin drivers in use today.
Bobbin holder: The bobbin holder, commonly referred to as just "bobbin", is used to hold the thread bobbin when wrapping thread around the hook. The bobbin holder provides tension so that it can be released when the fly tyer is performing other tasks, such as wrapping hackle.
Winders have a center roll (a bobbin, spool, reel, belt-winding shell, etc.) on which the material is wound up. Often there are metal bars that travel through the center of the roll and are shaped according to their intended purpose. A circular bar facilitates greater speed, while a square bar provides a greater potential for torque.

A single drive wheel set up in Scotch tension has one drive band connecting the drive wheel to the flyer. The spinning drive wheel turns the flyer and, via friction with the flyer shaft, the bobbin. A short tension band, or brake band, adds drag to the bobbin such that when the spinner loosens their tension on the newly spun yarn, the bobbin ...
