Drafting method and dropper

The invention relates to a drafting method and a dropper and solves the problem of drafting before weaving. According to the technical scheme, elastic clamping jaws are processed on the dropper; process through holes are formed in harness wires; the process through holes in the harness wires correspond to the clamping jaws on the dropper; before drafting, the harness wires are inserted in the clamping jaws on the dropper in advance and attached to the clamping jaws, so that the requirement of overlapped drawing-in holes is met. Accordingly, each warp can draft the harness wires and the dropper simultaneously; after drafting of the whole rank or the whole shaft is completed, the harness wires and the dropper are separated intensively. According to the drafting method and the dropper, efficiency is improved, and difficulties are reduced.
