screws 57 electrical leads 58 are connected to control arrangement 31 in this way guides 12 may be displaced in the manner of a jacquard control with respect to further specific questions of such jacquard control with piezoelectric bending transducers reference is made to applicant 39 s prior german patent applications namely p 42 26 899 u s ser no 08 1 04 369 p 43 16 396 p 44 14 876 u s ser no 08 426 887 and p 44 18 714 u s ser no 08 412 167 whose disclosure is incorporated herein by reference the construction of the piezoelectric bending transducers described in the foregoing applications may be similarly utilized for bending transducers 13 through 15 of the present application this structure may also apply as well to the provision of a second bending transducer in the region of the extension 43 of fig1 which can bend in a direction opposite to that of the first bending transducer by means of the second bending transducer the lower end of the strip formed carrier is displaced parallel to itself during the bending formation the loading of the carrier on the attachment point on the guide bar side is therefore minimal fig8 illustrates the upper end of the bending transducer 59 a strip formed carrier 60 is made of a synthetic material strengthened with carbon fibers which makes it electrically conductive on one side it carries a layer of piezoelectrically active material 61 having an outer electrode 62 and on the other side there is coated a piezoelectrically active layer 63 having an outer electrode 64 the outer electrode 62 is connected with.
