Patent number: 9283734Abstract: The present invention provides for a manufacturing apparatus for forming a ceramic preform from an extrudate having a first end and a second end. A cutter forms the first and second ends of the extrudate complementary to each other such that the first and second ends of the extrudate align with each other in a spaced relationship to define a preform having a substantially uniform exterior surface and a substantially uniform thickness. The present invention provides for a method of forming the preform from the extrudate having the first and second ends utilizing a mandrel. The method includes the step of aligning the second end complementary to the first end of the first layer in a spaced relationship to define the preform having the substantially uniform exterior surface and the substantially uniform thickness.Type: GrantFiled: May 31, 2011Date of Patent: March 15, 2016Assignee: GUNITE CORPORATIONInventors: Neil Anderson, Matt Kero
