Abstract

Tubular filters are made by automatically assembling paper elements and annular metal covers so that the components are bonded by an adhesive coating which can be heated and cured by high frequency induction without a significant drop in viscosity. The covers and the usual perforated coaxial filter core tube are made of material which is electrically conductive. Used esp. for mfr. of filters for treating fuels or lubricants, e.g. car engine oil. The process can oprate with much better thermal efficiency than processes which involved significant heating of the bodies of the cover plates and core tubes either incidently or as the means for transferring heat to an adhesive coating.
