A bending machine with a compact bend arm includes in a bend arm ( 4 ) being mounted on a rotating spindle ( 3 ) a cylinder which is fed with a pressured fluid through hoses ( 7 ) being part of a hydraulic circuit connected to a source of pressured fluid and of an electric circuit. Each of the hoses ( 7 ), which are side by side, comprises a curved section ( 7 a) around the rotating spindle ( 3 ), the curved section ( 7 a) being radiused at one end to a section ( 7 b) parallel to the bend arm ( 4 ), and at the other end to a section ( 7 c) directed to the rest of the bending machine, to which hoses ( 7 ) are retained. In the section ( 7 b) parallel to the bend arm ( 4 ) the plurality of hoses ( 7 ) are clamped on a slider ( 9 ) slidable in a prismatic guide ( 10 ) which is provided in the bend arm ( 4 ).
