Abstract
An apparatus for forming honeycomb-type core strip includes a source of metallic ribbon, form gears for forming a desired configuration in the ribbon and take-up means for taking up the core strip as it is issued from the form gears. Interposed between the source and take-up means is lubricating means for insuring adequate lubrication of the metallic ribbon as it enters the bite of the form gears. The form gears are characterized by a configuration which enables them to impart hinge means to the ribbon which facilitates the utilization of the ribbon in unitary metallic seal constructions wherein a continuous length of the ribbon is bent into helical form.
