ABSTRACT:
A honeycomb core manufacturing machine which includes a mainframe assembly and a transport assembly carried by and translatable along the mainframe assembly. The mainframe assembly comprises vertical and horizontal translatable upper and lower weld electrode assemblies. The transport assembly comprises upper and lower weld wheel electrode assemblies, an upper and lower weld electrode spreader assembly and a corrugated ribbon strip placement mechanism for placing ribbon between the spread apart upper and lower negative weld electrode assemblies with crest and trough of adjacent layers in registry. Sequentially as the transport assembly translates to and fro across the mainframe assembly between discrete weld stations, the upper and lower weld assemblies are spread apart, ribbon is placed between them, they then return to their non-spread apart locations by spring bias holding the corrugated ribbon in a weld position, the upper and lower weld wheel assemblies rotate from their non-weld position to their weld position where they engage and roll across the outer surface of the last placed foil ribbon layer and weld current passes between the weld wheel electrodes and weld electrodes through the adjacent ribbon layers welding them together at their registry, the upper and lower weld wheel assemblies then rotate back to their non-weld position and the same sequence of events is repeated until a sufficient length of core is produced.
