Once the warp is set up on the loom, the cloth can then be woven (by sending weft threads across and through the warp). The weft is carried straight off the cone, through an accumulator by the left-hand rapier. This meets the right-hand rapier which catches the weft and takes it across the remaining width of the cloth. As the rapiers meet in the middle of the cloth, the weaving process is quicker and more efficient than weaving with flying shuttles. In fact, they move so fast it can be difficult to see them.
