- Shuttle: Carries the weft yarn
- Reed: Pushes the weft into place
- Harnesses: Control warp thread movement
When you use a shuttle loom, you’ll notice it follows a specific sequence. First, the harnesses raise and lower to create the shed. Then, the shuttle passes through, leaving behind the weft yarn. Finally, the reed beats the weft into place, creating the fabric.
Warp-Weighted Loom
The warp-weighted loom is an ancient weaving device that has been used for centuries. This type of loom is characterized by its vertical structure, where the warp threads are held taut by hanging weights. As you operate the loom, you’ll notice that the weft threads are inserted horizontally, creating the fabric’s pattern.
When using a warp-weighted loom, you’ll start by attaching the warp threads to a horizontal beam at the top. The bottom ends of these threads are then grouped and tied to weights, typically made of stone or clay. As you weave, you’ll use a shed rod to separate alternate warp threads, creating an opening called the shed. Through this shed, you’ll pass the weft thread using a shuttle. The weft is then beaten into place with a sword beater, gradually forming the fabric from top to bottom.
Rapier Loom
The rapier loom is a sophisticated weaving machine that utilizes a unique weft insertion method. It employs long, thin rapiers to carry the weft yarn across the warp shed. These rapiers can be rigid or flexible, and they work in pairs, one from each side of the loom. As you observe the process, you’ll notice that one rapier passes the weft to the other at the center of the shed, ensuring precise yarn placement.
Rapier loom is versatile, as it can handle a wide range of yarn types and produce complex fabric patterns.
