Glazkov UDC 621.757.06:[62-216.8+62-465] When cylindrical products with elliptical or spherical bottoms with great stiffness are produced, the alignment of the elliptical edge of the bottom in contact with the shell requires a large force; this may lead to buckling of the spherical part of the bottom. In the practice of assembly of rigid bottoms and nonrigid shells it is usual not to align ellip- ticity separately but to match the edges of the nonrigid parts (shells) to the edges of the rigid parts (bottoms). Up to now these operations have been carried out manually with the aid of shackles and wedges welded to the contacting elements [i]. At the All-Union Research and Project Institute for the Technology of Chemical Machinery (VNIIPTkhin~nash) an installation [2] was designed which makes it possible to mechanize the assembly of bottoms and shells and to effect it at once over the entire perimeter of contact. Uniform distribution of the difference in diameters and length of the circles of the contact- ing elements over the entire perimeter of contact is ensured, as well as setting of their edges with equal displacement, independently of the deviation of dimensions
