The flower book is a set of procedures for storing pattern information on the jacquard machine

The flower jacquard machine appeared in the Eastern Han Dynasty, also known as the flower building. It is the representative of the highest achievements of ancient weaving technology in China. It stores the jacquard program with a threaded flower book, and then uses a wire to pull the warp opening. The flower book is a set of programs to store pattern information on the jacquard machine, which is woven by the foot line representing the warp thread and the ear wire representing the weft line according to the pattern requirements. When the machine is on, the foot wire is connected to the fiber wire of the lifting warp, at this time, the foot wire on the side of the ear wire can play the role of lifting the relevant warp. When weaving, two people cooperate up and down, one is a flower puller, sitting on a three-foot-high flower building to pull flowers and weave, and one person steps on the pole to lead the weft weaving. In Wang Yi's "Machine Woman" of the Eastern Han Dynasty, he used "slender and quiet woman, meridian network, shaken and multi-faceted, and pitched up" to describe the scene of weavers and jacquard workers cooperating to manipulate jacquard machines.
