PURPOSE:When the yarn is in the yarn connector and bends out of the normal running course, it is cut and held so as to collect the sample yarn as long as possible from a winding unit. CONSTITUTION:The yarn end in the winding package 17 is held by sucking with a mouth 70 and the yarn is guided to the connector T while the other yarn on the feed bobbin side 18 is held by sucking with the connection pipe 71 and guided to the yarn connector t. Yarn cutting and holding is effected before the completion of yarn connection to cause the yarn to bend between holding points P and Q and the bended yarn is collected as a sample. |
