Yarn layering device for warping machine

The utility model provides a yarn layering device for a warping machine, which comprises a batten and a plurality of dents mounted on the batten, and is characterized in that a plurality of equal-height heightening blocks are added, wherein grooves are arranged on the two sides of each heightening block, the heightening blocks are combined with the dents through the grooves on the two sides thereof, and are inserted at intervals between every two dents, and the low ends thereof are backed against the batten. A plurality of equal-height heightening blocks are inserted at intervals between every two dents through grooves on the two sides thereof, therefore the yarn passing through the yarn is bound to be divided into an upper and a lower layers at intervals through the heightening blocks, and lease yarn can pass through the two layers with ease, thereby shortening the time of lease yarn passing to a great degree, reducing the labor intensity, improving the working efficiency, and increasing the warping output.
