Abstract
A looper threading apparatus includes a threading member capable of holding a thread in a tip portion and inserting the thread through a thread hole, a guide member for movably accommodating the threading member and guiding the threading member to the thread hole, and a support member for supporting the guide member to freely approach and separate from the thread hole provided on an extended line of the threading member accommodated by the guide member. Moreover, there is provided a moving mechanism for moving the threading member and the guide member along an axis of the thread hole provided on the extended line. The moving mechanism moves the guide member and the threading member with respect to the thread hole provided on the extended line in such a manner that the tip portion of the threading member penetrates through the thread hole.
