ABSTRACT:
An electronically controlled sample warper includes a yarn introduction member movably mounted on a distal end of a yarn introduction lever rotatably provided on a side surface of a warper drum for winding a yarn on the warper drum, and a plurality of yarn selection guides disposed, in correspondence with the yarn introduction member, on an end portion of a base on which the warper drum is supported. Each of the yarn selection guides is movable angularly about the base between a yarn exchange position in which it projects from the base for changing the yarn to another yarn, and a standby position in which it is retracted in the base for storing the yarn in the base. The yarn introduction member and each of the yarn selection guides are cooperative to undertake delivery of a yarn between them so as to wind yarns on the warper drum in the preset order with automatic yarn change. For delivery of the yarn from the yarn introduction member to any of the yarn selection guides, the yarn introduction member moves in a direction to release the yarn to thereby allow the yarn to be caught by the yarn selection guide, and for delivery of the yarn from the yarn selection guide to the yarn introduction member, the yarn introduction member moves in another direction to catch the yarn held on the yarn selection guide.
