Sewing machines with vertical shuttle hook

Vertical rotary shuttle

— in many features, such shuttles are similar to oscillating ones (see the relevant paragraph): in particular, they are relatively easy to adjust the thread tension, but to refill the bobbin, you must always climb into the mechanism and remove the bobbin case from the shuttle. The key difference is that the shuttle does not oscillate during operation but rotates. Because of this, such mechanisms are somewhat more complicated and more expensive than oscillating ones. However, they provide a higher sewing speed with a lower level of vibration and noise. This option is used in professional and semi-professional machines, as well as industrial equipment.
