Abstract
Abstract A system for construction of ship sections. Mechanized devices are provided for assembling two-dimensional and three-dimensional sections from individual parts, under control of automatic and easily computerized mechanisms for forming, positioning and welding the sections. Sequences or systems of such devices and control mechanisms, for making flat or three-dimensional sections, are largely disposed in parallel, and the materials are conveyed in uniform directions along the parallel lines. Intermediate storage facilities are provided for compensation of slack in any of the parallel systems. Also provided is an ultimate receiving and finishing section, for work on elements from the preceding sections. Ship plates move along the several lines on trolleys equipped with suitable holders, and are processed by multiplicities of steel plate processing machines, basically known by themselves but specially arranged to suit the new system.
