To provide a sample warper having switching means with bobbins, capable of switching the yarns of yarn guides to winding yarns for being wound on a warper drum and resting yarns without being wound on the warper drum by the switching means with bobbins (yarn-selecting means) capable of setting patterns by a multiple number of yarns of two switching means with bobbins by following pattern data (a yarn arrangement order and color yarn arrangement order) set in advance by using a rotary yarn-feeding device installed as opposing to the warper drum.

This sample warper is provided by making the yarn guides as a fixed type, installing a ring-formed guide rod having a first opening part and second opening part between the warper drum and rotary yarn-feeding device, and selecting the yarns drawn out from each of the bobbins as the winding yarns being wound on the warping drum and the resting yarns without being wound on the warping drum by the switching means with the bobbins of the 2 switching means with the bobbins consisting of the first switching means with the bobbins and second switching means with the bobbins.
