The paper is concerned with an analysis and optimisation of the needle transfer mechanism by meansof the software Pro/Engineer Wildfire 4 with the aim to obtain a reduction of needle wear. Anoptimisation of parameters of the setting mechanism that influence the moment of release of the needleduring its transfer from one needle bar to the other has been carried out. As a result the optimalsetting of the needle transfer mechanism was found. Modifications of the design of the needle transfermechanism were proposed which are leading to improved force effects in the gripping of the needle.The results have been experimentally verified by the long-term operation of a functional model.
