• the improvement comprising:
• the lifting knives of each set of lifting knives being linked to at least respectively one oscillating shaft;
• an eccentric gear unit having a rotating shaft rotatable by the driving arrangement, and an eccentric of said gear unit pivoting the respective oscillating shaft by bearing on a follower roller means non-rotatably secured to said respective oscillating shaft, the oscillating shafts being mounted in the machine frame at right angles to the reach of the lifting knives and to the direction of movement of the lifting knives, the length of the oscillating shafts being dimensioned such that a number of sets of lifting knives corresponding to a maximum weaving path is linkable thereto.
