What is another word for a bobbin?

A shuttle is used to place the weft or crosswise threads while weaving on a loom. There are several styles of shuttles. Inside a boat shuttle is a bobbin that holds the weft thread. An end-feed shuttle has a bobbin inside that is called a pirn. A bobbin winder is used to load the thread on the bobbins. A ski shuttle is used for coarser weft and has a flat base that looks much like a ski - the ends are curved upward slightly and allows it to slide quickly through the opened shed in the warp threads. Ski shuttles and stick shuttles are wound by hand. A stick shuttle is a flat piece of wood of varying lengths with carved ends to keep the weft wrapped until it is unwind during the weaving process. Some stick shuttles have sharp edges to help beat the weft in place as when using a inkle loom.
