behind the position corresponding to fig1 is not illustrated it corresponds apart from the 180 u00b0 turned round position of the two upper blocks in all the details to fig1 also this block is thus guided against the front support device 28 but on account of the lack of ferromagnetic portions it is not held there so that on the rearward movement of the carrier 21 the block is also moved backwards therewith until it abuts with its rearwardly lying binding 14 the stop 37 of the support device 29 which has been guided upwards again in the meantime the force pulling back the block 13 is accordingly the frictional force of the block on the carriers 21 this position is shown in fig4 the carrier is now moved out further from under the block and in similar fashion as illustrated in fig3 the block is freed from the carriers 21 and the holding device 38 so that it falls in the pile shaft 26 on to the pile 47 however in this case the binding 14 is held against the support device 29 and drops guided by this downwards thereafter the already described cycle repeats itself for changing the pile i e the removal of a finished form pile by means of the action device 31 and parallelogram linkage 30 the front support device 28 is swung out and the pile moved out by a horizontal movement of the support device 29 or by means of special pushers not illustrated from the pile table in the transport direction in the case of the use of bindings without ferromagnetic parts for example of plastics spirals or plastics comb bindings the front support.
