Bucher Emhart Glass recently led a project to create the first quad gob arcuate pneumatic IS machine, in partnership with SGD Kipfenberg, as Leo Diehm and Rainer Becker explain. The story is based on the fact that the 54mm quad gob had become ‘orphaned’. This technology was based on 4¼in section boxes, originally designed and produced in-house by SGD/Bormioli during the 1960s. Since the designers were no longer developing it, the parts and mechanisms became obsolete and it was not supported by a machine supplier.
