Abstract

There is provided a sample warper with an idle running preventing mechanism of a yarn guide, wherein yarns are automatically exchanged and successively wound on the warper drum according to a preset yarn order by passing the yarns between the yarn guides and the yarn selection guides, and wherein, when a first yarn being wound on the warper drum by a first yarn guide is exchanged to a second yarn, after a yarn removing operation for removing the first yarn from the first yarn guide is finished, a yarn feeding operation for feeding the second yarn to a second yarn guide is performed while the empty first yarn guide makes one rotation. The sample warper can achieve such an advantage that an idle running time of a yarn guide when exchanging yarns can be reduced considerably and a speed of yarn exchanging is improved remarkably.
