A process and apparatus for strand transfer is disclosed. The transfer occurs during the exchange of two winding collets in which the first, full collet, is shifted to the position where it is emptied while the second, empty collet, picks up the strand. According to the disclosure, the linear drive speed of the first collet is reduced; the arc of contact of the strand on the circumference of the second collet is increased as the second collet arrives at the position previously occupied by the first; the portion of the strand travelling from one to the other is engaged between the collets and the engagement of this portion is maintained and progressive breaking of the strand by abrasion is effected until the second collet takes up the strand. A novel device comprising a moveable means capable of introducing and maintaining the strand in position between the two collets and abrading the strand until the transfer has taken place is disclosed.
