element 11 is in its lowest position the protrusion 12 presses against protrusion 15 accordingly jacquard guide 8 is pressed to the right until it contacts the right hand stopper surface 17 the lower ends 9 are thus presented exactly to the gap between needles in the embodiment of the invention shown in fig4 a and 4b the correspinding parts are incremented by a figure of 100 over the embodiments of fig1 through 3 in this embodiment guides 108 are provided with two crimps 115 and 125 facing in opposite directions correspondingly sliders 111 are provided with two displacement elements 112 and 126 which have a jog to the left and right respectively as viewed in fig4 a in this mode of construction th jacquard guide 108 need not be provided with any recovery spring force it is positively pressed against stopping elements 117 when displacement element 112 acts upon protrusion 115 similarly it is pressed against stop 116 when displacement element 126 presses against protrusion 125 the force locking contact to one or the other stopping surfaces 116 117 occurs as a result of the influence of the displacing elements 112 126 while the force locking contact onto one contact surface could occur as a result of the elastic return force of the jacquard guide in this embodiment jacquard guide 108 is displaced positively by providing two displacing elements 112 and 126 on both sides of the jacquard guide 108 and activating them alternately in this embodiment.
