Abstract (en)
In the coupling arrangement, before any selection all the armatures (53) are brought directly up against the respective associated electromagnet (51) by the cam shaft (92) having a flattened portion (91). Thereupon, only those electromagnets (51) in which the armatures (53) are to remain pulled up are made live. When the cam shaft (92) rotates in reverse, the flattened portion (91) comes in front of the armatures (53) again. Those armatures (53), the associated electromagnets (51) of which are non-energised, are thereby transferred under the effect of the spring (69) into the spaced position shown in Figure 2. During the next sensing by the arm (33), its upward movement is blocked (detent position 33a). The sinker (23) thereby continues to be held in the region of the lifting knife (25) and is moved to and fro by this. The electromagnets (51) can consequently be made relatively small, and the stroke of the armatures (53) can be kept relatively large to ensure an increased safety of the mode of operation of the tracer (33). Because of the smaller size of an electromagnet, its magnetic field cannot become effective in the region of an arm (33) belonging to the adjacent magnet. <IMAGE>
