The purpose of the invention is to allow displacement of the arm (10), designed to save space of the shaped longitudinal member segments spatially shaped path, a desired angle without causing the collision to the longitudinal member with plate (6) cradle. The said purpose is achieved by a positioning device comprising a frame (1) with a displaceable vertically placed extension (2), at the upper end with a horizontally oriented rotatable plate (3) from which the of column brackets (4) pivotally mounted cradle, made up of two side segments (5) to which is fixed the plate (6) to which are fastened the top wall extending arms (8), wherein of the stored pivot arm (10) for receiving spatially shaped longitudinal members segments. The plate (6) is curved in the vertical direction such that the long edges (7) located below the fastening point of the boom bracket (8) on the plate (6). The plate (6) is preferably curved in the shape of arc of the cylindrical tube cross section. The arm (10) is fixed to the support (11). |
