<p>ARRANGEMENT FOR MANUFACTURING SPHERICAL RESERVOIRS Arrangement for manufacturing spherical reservoirs from meridional petal-like flaps, wherein the base has mounted thereon a supporting frame for the reservoir, and, successively overlying this frame: a shaft for accom?odating the lids of the reservoir and for rotating the latter in the process of its manufacture, and a welding unit accom?odated on a support beam. The shaft is journalled on posts mounted on the base, for rotation about a horizontal axis, while the supporting frame has a curvilinear surface for the meridional flaps to be placed thereupon, the shape of this surface corresponding to the curvil inear surface of the meridional flaps, the frame being carried by vertical guides for motion therealong, to bring the meridional flaps to the lids of the reservoir. The support beam has made thereon arcuate guideways of a radius somewhat greater than that of the sphere of the reservoir, to accom?odate the welding unit for motion therealong in the course of welding the reservoir. The arrangement of the present invention is highly efficient and structurally simple; it provides for performing the entire production sequence of assembling a reservoir, while not requiring great production space for its accom?odation.</p> |
