corresponding to 1 is associated project out of the needle bed however as the selection point 180 at this time is only located on one of the selected selector bars and all the other selection points 181 182 and 183 are located on other bars only this one bar is selected at this time fig2 shows the section of a selection point the carriage 163 moves with its guide 204 on a guide rail 205 over the needle bed 164 a control device with adjacent magnets 206 in the form of electromagnets is located behind the needle bed 164 when the magnet 206 conveys current as shown in the example a locking spring 208 is either attracted by the cores 207 of the magnets 206 or is cushioned by its own elasticity in the cushioned state the locking spring 208 blocks a spring 209 which is pressed into the needle bed 164 by the selector 210 during the passage of the carriage if current has been supplied to the magnet 206 as shown in the embodiment represented it grips the locking spring 208 against its core 207 the spring 209 pushes the selector 210 upwards until its foot 212 can be gripped by the locking element 211 this locking element 211 pushes the selector 210 and thus the needle 213 upwards so that its foot 214 can be gripped.
