       17 . The loom of  claim 15 , further comprising a support ( 8 ) for said warp beam ( 2 ), and markings positioned on said drive means ( 3 ) and on said frame wall ( 4 ) for indicating when said support ( 8 ) is in a warp beam holding position, wherein said support ( 8 ) has warp beam supporting elements rotatable with said drive means ( 3 ) and wherein said support ( 8 ) is arranged at said drive means ( 3 ) on a warp beam facing side. 
   
   
       18 . The loom of  claim 16 , further comprising a support ( 8 ) for said warp beam ( 2 ), and wherein said at least one screw ( 6 ) and said number of screws ( 6 ) can be screwed into said threaded hole or holes in said warp beam flange only when said support ( 8 ) is in a warp beam holding position, wherein said support ( 8 ) has warp beam supporting elements rotatable with said drive means ( 3 ), and wherein said support is arranged at said drive means ( 3 ) on a warp beam facing side. 
   
   
       19 . The loom of  claim 16 , wherein said through holes ( 3 . 1 ) of said second plurality of through holes ( 3 . 1 ) are arranged in accordance with an asymmetric hole pattern, wherein said through holes of said third plurality of through holes ( 4 . 1 ) are also arranged in accordance with said asymmetric hole pattern, and wherein said drive means ( 3 ) is positioned so close to said frame wall ( 4 ) that said at least one screw and said number of screws can pass through respective through holes of said second and third plurality of through holes only when said respective through holes of said second and third pluralities of through holes are in an axial alignment with one another and with said threaded hole or holes, said loom further comprising a warp beam support ( 8 ) in a warp beam holding position for said threaded screws to pass through said respective through holes of said second and third plurality of through holes for engagement with and disengagement from said threaded hole or holes. 
   
   
       20 . The loom of  claim 15 , wherein said at least one screw ( 6 ) can pass through said at least one first through hole and through said at least one second through hole when said first and second through holes are in axial alignment with one another, said loom further comprising a warp beam support in a warp beam holding position for said at least one screw to pass through said first and second through holes. 
   
   
       21 . The loom of  claim 16 , wherein said first plurality of threaded holes ( 2 . 4 ) comprises such a number of threaded holes, that said warp beam flange ( 2 . 2 ) can assume any one of a plurality of angular positions relative to said drive means and relative to a common axis ( 5 ) of rotation, said warp beam flange ( 2 . 2 ) being connectable to said drive means ( 3 ) by said separable screw connection in any one of said plurality of angular positions. 
   
   
       22 . The loom of  claim 15 , wherein said at least one screw is constructed as a dowel or fitting screw. 
   
   
       23 . The loom of  claim 15 , wherein said at least one second through hole ( 4 . 1 ) in said frame wall ( 4 ) is so dimensioned that said at least one screw, as it passes through said at least one second through hole, is operable in said at least one second through hole, wherein a spacing between the drive means and the frame wall is short enough so that said at least one screw can reach into said at least one second through hole ( 4 . 1 ) in response to a biasing force pushing said at least one screw ( 6 ) into said at least one second through hole ( 4 . 1 ) in a direction opposite a screw-in direction when said at least one screw is still disengaged from said at least one threaded hole in said warp beam flange so that a rotational motion of said drive means ( 3 ) exceeding a predetermined rotational angle is blocked by said at least one screw reaching into said at least one second through hole ( 4 . 1 ). 
   
   
       24 . The loom of  claim 23 , comprising a screw biasing energy storing device for applying said biasing force to said at least one screw.
