ABSTRACT:
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 accommodating the lids of the reservoir and for rotating the latter in the process of its manufacture, and a welding unit accommodated 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 curvilinear 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 arcuate guideways of a radius somewhat greater than that of the sphere of the reservoir, to accommodate the welding unit for motion along the guideways 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 accommodation.
