Automatic loom with changeable bobbins

Japanese: 管替式自動織機 - かんたいしきじどうしょっき
Automatic loom with changeable bobbins

...A power loom that continues to operate by automatically replenishing the weft thread when it breaks or is about to run out during operation. Shuttle looms, which use a shuttle containing a wooden tube with the weft wound on it, come in two types: shuttle change, in which the shuttle is replaced, and cop change, in which only the wooden tube is replaced, but the cop change type is more common. With the cop change type, there is a risk of damaging the weft thread when refilling with a new wooden tube, but this is usually not a problem. With shuttleless looms, the weft is inserted directly from a cheese or other material that has a large amount of weft wound on it, so it can be refilled less frequently and more easily.
