Methods of manufacturing a honeycomb structure comprise the step of providing a honeycomb body having a multiplicity of cells extending therethrough between opposing end faces. The cells are defined by intersecting porous walls. The methods further include the steps of applying an after-applied skin layer on the honeycomb body and chamfering an edge of the after-applied skin. The chamfering step is performed on a wet after-applied skin layer.

Methods and apparatus for making honeycomb structures with chamfered after-applied akin and honeycomb structures produced thereby

Methods are provided for applying a layer to a honeycomb body. The methods include the steps of applying a cement mixture to a cylindrical surface of the honeycomb body and rotating the honeycomb body and a blade relative to one another about a longitudinal axis of the honeycomb body. The methods further include the steps of holding the blade at a first interior angle during a relative rotation of the honeycomb body and the blade about the longitudinal axis. The methods then include the step of moving the blade from the first interior angle to a second interior angle greater than the first interior angle. The methods still further include the step of rotating of the honeycomb body and the blade relative to one another about the longitudinal axis after the blade begins to move from the first interior angle toward the second interior angle.
