The presses are generally hydraulic, although small hand-operated presses (such as arbor presses) may operate by means of the mechanical advantage supplied by a jackscrew or by a gear reduction driving a rack and pinion. The amount of force ...

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.
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.
