ABSTRACT:
An essentially non-contact holddown system for a corrugator double backer utilizes vacuum pressure through the lower heating section which supports the double face corrugated web. Continuous edge sealing membranes overlie the edges of the web and form, with the web edge and the surface of the heating section, vacuum chambers into which air is drawn from the flute spaces in the double face web.
