What does a shuttle do in textile production?

In textile production, a shuttle is an essential tool used specifically in the weaving process. Its primary function is to carry the weft thread across the warp threads. The shuttle moves back and forth across the loom, weaving the weft in and out through the stationary warp threads, which creates the fabric. This action is crucial for the interlacing of threads that forms textiles. Consequently, understanding the role of the shuttle provides insight into the basic mechanics of weaving, illustrating how fabrics are constructed. The other options focus on different aspects or tools used in textile production that do not pertain to the shuttle’s specific function.
