Abstract
A device for forming a transfer tail wind around a bobbin held by a take-up mechanism of a ringless spinning machine such as an open-end spinning machine. The tail wind forming device comprises an auxiliary yarn guide disposed at a position along a yarn passage formed between the delivery roller means and a traverse motion mechanism of the take-up mechanism. The auxiliary yarn guide is provided with a groove for restricting the above-mentioned yarn passage to a position corresponding to an end portion of the bobbin, where the yarn is free from the traverse motion mechanism, when the transfer tail wind is being formed on the bobbin.
