An embroidery apparatus is configured to perform an embroidery operation according to embroidery data. The embroidery apparatus includes a thread assumed consumption amount calculator configured to calculate an assumed consumption amount of a thread in the embroidery operation, based on initial embroidery data input in advance; a thread consumption amount detection mechanism configured to detect an actual consumption amount of the thread; and a thread consumption amount adjuster configured to adjust the actual consumption amount of the thread in the embroidery operation by adjusting output embroidery data to be output, based on a difference between the calculated assumed consumption amount of the thread and the detected actual consumption amount of the thread.

Embroidery and sewing machines can utilize rotary hooks to attach thread to materials. An adhesive joint configured to sever if the rotary hook becomes jammed prevents damage to the rest of the drive system. The severable joint is located between a sleeve and a drive shaft nearest the rotary hook to allow for easy removal and repair of the joint.

The present invention relates to a vertical full-rotation shuttle, which leads a feed-side string portion of a needle thread loop to be wound around and hooked to a bobbin thread from one side of a bobbin case to the other side thereof according to the rotation of a hook part, and leads a stitch-side string portion of a needle thread to the surface of the bobbin case at one side of the bobbin case, such that the feed-side string portion of the needle thread turns the bobbin thread around and the needle thread loop jumps over the bobbin case so as to form complete stitches

A thread-cutting mechanism of an embroidery machine, and a tube embroidery machine applying the same are provided. A movable knife frame provided at a periphery of a rotary shuttle can drive a movable knife to rotate around the rotary shuttle and coordinate with a stationary knife to cut a thread. The movable knife frame is rotatably provided at a periphery or one side of a driving shaft of the rotary shuttle. The movable knife frame is rotatably mounted on a needle plate seat, or on an embroidery machine body, at a corresponding location for cooperation with the rotary shuttle. The stationary knife is mounted on the needle plate seat, or on the embroidery machine body, at a corresponding location for cooperation with the rotary shuttle. This substantially reduces the space occupied by the movable knife. The thread-cutting mechanism is more compact, simple, compatible, and easy to use.
