Abstract
A sample yarn-collecting apparatus for preparing a continuous yarn knotted in an end-to-end manner, in which sample yarns having a certain length are collected from a plurality of yarn packages, each of them are connected in succession in an end-to-end manner to obtain one continuous yarn, and the continuous yarn is wound temporarily and thereafter continuously unwound to be fed to testing means while storing it in a quantity within a predetermined range, is disclosed. This apparatus comprises sample yarn collecting means for collecting sample yarns from packages and connecting each of them to form one continuous yarn, means for storing the continuous yarn fed from said collecting means on a rotary member by winding it and feeding the continuous yarn wound and stored on the rotary member to testing means by unwinding it, and supplementary means for controlling the above two means.
