Claim:
Drive system for a weaving loom comprising: a switching wheel ( 5 ) arranged to be driven by a main drive motor ( 7 ) and which is axially displaceable between at least two switching positions, including a first switching position, which is in drive connection with first and second groups of elements to be driven ( 9 , 10 , 11 ; 12 , 13 , 14 ), and a second switching position, which is in drive connection with the first group of elements to be driven ( 9 , 10 , 11 ) and disengaged from the second group of elements to be driven ( 12 , 13 , 14 ); and a holding device ( 15 ) which becomes active as the drive connection of the switching wheel ( 5 ) with the second group of elements to be driven ( 12 , 13 , 14 ) is disengaged and which holds the second group of elements to be driven ( 12 , 13 , 14 ), which is disengaged from the switching wheel ( 5 ), in a defined position, said holding device ( 15 ) including a tooth element separate from the switching wheel ( 22 , 26 ) which selectively engages in a large number of defined positions with teeth of a gear wheel ( 12 , 34 ) of the second group of elements to be driven ( 12 , 13 , 14 ) when the second group of elements to be driven ( 12 , 13 , 14 ) is disengaged from the switching wheel ( 5 ), the large number of positions being determined by the number of teeth of the gear wheel ( 12 , 34 ) of the second group of elements to be driven ( 12 , 13 , 14 ).
