Abstract: A control system for an axial skinning apparatus (100), including: •a force to cause a ceramic honeycomb part (110) to pass through the skinning apparatus (100); •a force that urges flowable cement on to the ceramic honeycomb part (110); •a sensor to detect the force on the cement; •a sensor to detect the force on the ceramic part; and •a controller (300) which receives: •a signal from the sensor on the flowable cement, •a signal from the sensor on the ceramic part (110), or both, and the controller (300) controls the pressure set point (310) of the cement source based on one or both of the received signals, and the controller (300) adjusts control parameters using feedback control and pseudo feed forward control. A method of using the axial skinning apparatus (100) is also disclosed.

Abstract: A method and system to dry crack-free and high strength skin including an inorganic binder of an average particle size (D50) in a range between 10 nm and 700 nm on a porous ceramic body. The method includes supporting the honeycomb body on an end face such that axial channels and outer periphery are substantially vertical. A gas is flowed past the honeycomb body substantially parallel to the axial channel direction, substantially equally around the outer periphery of the skin, to uniformly dry the skin to form a partially dried skin under mild conditions. Then the partially dried skin may be dried more severely resulting in rapidly dried crack-free and high strength skin.
