Flow applicator apparatus and methods of applying a layer of cement material to a honeycomb body

A method of applying a layer of cement material to a honeycomb body comprising a longitudinal axis extending through opposing end faces and an outer circumferential surface extending about the longitudinal axis and between the end faces, the method comprising the steps of:

• (I) providing an applicator body including an interior area, a dispensing port and an oscillatory member;
• (II) charging the interior area with cement material;
• (III) oscillating the oscillatory member to modify a material property of the cement material;
• (IV) dispensing the cement material from the interior area through the dispensing port;
• and
• (V) applying the cement material to the outer circumferential surface of the honeycomb body.

A method of applying a layer of cement material to a honeycomb body comprising a longitudinal axis extending through opposing end faces and an outer circumferential surface extending about the longitudinal axis and between the end faces, the method comprising the steps of:

• (I) providing an applicator body including an interior area, a dispensing slot including a static width defined by a distance between a first lip and a second lip, wherein the first lip is defined by an oscillatory member and the second lip is defined by a fixed portion of the applicator body;
• (II) charging the interior area with cement material;
• (III) oscillating the oscillatory member to provide a dynamically changing width between the first lip and the second lip;
• (IV) dispensing the cement material from the interior area through the dispensing port, wherein a viscosity of the cement material is reduced by the dynamically changing width between the first lip and the second lip as the cement material is passed through the dispensing slot;
• and
• (V) applying the dispensed cement material to the outer circumferential surface of the honeycomb body.
