Applying the method of direction cosine matrix and imaginary removal of certain links, moreover according to the identity conditions of mechanism motions, displacement equations of a closed differential type compound spatial linkages are derived. The main part of this linkage is a spatial five-bar with two degrees of freedom. By composite on it a planar and a spatial four-bar, the resultant linkage forms a closed differential type with only me degree of freedom. The linkage used in the GK13-1 three needle flat-seaming machine is an example and the spatial coupler curve traced by the looper point is caculated and shown graphycally.
