Sample warper with detector for yarn on yarn guide

Abstract

A sample warper including a plurality of yarn guides, rotatably mounted on one side surface of a warper drum, for winding a plurality of yarns on the warper drum, a yarn selector mounted on a base supporting the warper drum for supplying the individual yarn selectively to one of the yarn guides and receiving selectively the yarn from one of the yarn guides, and a rotary creel supporting a plurality of bobbins of various kinds and/or a single kind of yarns. To detect a trouble, such as mis-winding or double-yarn-winding, the sampler warper is equipped with a yarn detector disposed adjacent to the peripheral edge of the warper drum for detecting whether or not the individual yarn is caught by the associated yarn guide, thereby confirming transferring of the yarn between said yarn guide and said yarn selector so that the yarns are successively wound neatly on said warper drum in preset yarn order.
