Apparatus for replacement of a winding bobbin on a shaft comprising a controllable arm for transport of bobbins to and from the shaft. The arm has a first number of grip members and a second number of grip members. The first number of grip members is symmetrically and peripherily placed relative to the arm and intended for engaging a bobbin. The second number of grip members is symmetrically and centrally placed relative to the arm and intended for fastening at a locking mechanism associated with the shaft, the locking mechanism being in a locking positon or a neutral position in dependence on the operation of the second number of grip members.
