a separation equal to two needle spaces additional strikers and are at choice made operative by the setting members of a stop control when one of the additional strikers is in an operative position that striker holds the guide in a central position in particular needle control and stop controls may operate with piezoelectric transducers in this manner it is possible to obtain an extremely large number of patterning possibilities application_number US 98568997 A description fig1 and 2 illustrate a jacquard guide bar 1 having a carrier 2 a first transducer unit 3 comprises an angled segment 4 which is connected to carrier 2 via a connection piece 5 the segment 4 carries sixteen first piezoelectric transducers 6 which each carry a guide 7 at their free end a second transducer entity 8 likewise comprises an angled segment 9 which is attached to carrier 2 via screw 10 the segment carries sixteen second piezoelectric transducers 11 which each have an abutment 12 at the free end thereof second transducer 11 is referred to as a setting means of a striker control means cable bundles 13 and 14 serve to connect the transducer units 3 and 8 with the appropriate control arrangements after their mounting on segments 4 and 9 left stops 13 and right stops 14 are part of a stop means provided to carrier 2 against which the guides 7 may rest under the influence of the appropriate transducer 6 as is shown in fig2 additional stops 15 and 16 also part of a stop means are provided at the lower end of a dual armed lever 17 which is swingable about a fulcrum 18 attached to the bar and whose upper end 19 extends into the region of the.
