Flexible mask and means for applying to honeycomb structures

摘要

This invention is directed to means for expediting the fabrication of selectively-manifolded honeycomb structures for use as fluid filter elements. The method comprises the use of flexible masks which are properly aligned to the end faces of a honeycomb structure utilizing vibratory motion in conjunction with a locating wire. By varying the configuration of the masks, it is possible to fabricate a fluid filter element having a center zone which is selectively manifolded and an outer portion wherein at least the ends of the honeycomb structure cells are completely filled.
