FIELD: conveyors. SUBSTANCE: to install a gutter on a column, the i -th obtained sections of the gutter are selected, one of the points of the line of intersection of the surface of the column with the plane of its support is taken as the origin of the circumferential X and vertical Y coordinates of the conveyor, then vertical lines are drawn on the surface of the column connecting the i-th sections of the gutter with plane of support of the column and lagging from the origin of coordinates along the circumference of the column at distances Xi, segments of length Yi are laid on the lines, measured from the line of intersection of the surface of the column with the plane of its support, after which the gutter of each i -th section is fixed with a side on the column at point c coordinates Xi, Yi. EFFECT: movement of transported objects along a spiral brachistochrone, which makes the speed of transporters as high as possible. 1 cl, 3 dwg.
