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.
The hook mechanism carries the upper thread entirely around the bobbin case so that it has made one wrap of the bobbin thread. Then the take-up arm pulls the excess upper thread (from the bobbin area) back to the top, forming the lockstitch. Then the feed dogs pull the material along one stitch length, and the cycle repeats.
Toilet-tissue winders are able to change over at running speed, while paper and board winders need to stop the winding process in order to cut the sheet and glue the paper on to a new wind-up core. Top-line winders introduce the paper core through a maintenance pit downstairs, with web interruption time as low as 15 seconds.

A vibrating shuttle is a bobbin driver design used in home lockstitch sewing machines during the second half of the 19th century and the first half of the 20th century. It supplanted earlier transverse shuttle designs, but was itself supplanted by rotating shuttle designs.
Rotary hook machines hold their bobbin stationary, and continuously rotate the thread hook around it. The design was popularized in the White Sewing Machine Company 's ' Family Rotary ' sewing machine [ 9 ] and Singer 's models 95 and 115.
