Abstract: A method and apparatus for edge finishing glass sheets. Glass sheets are separated into desired sizes, after which the edges of the glass sheets are finished using edge polishing methods, such as, for example, by contacting and moving the edges of the glass sheet against rotating polishing wheels which are oriented al least approximately orthogonally to said sheet.

Abstract: The present invention relates to an apparatus for cutting a mass of material which includes an elongate wire, a first drive for moving the cutting wire along its length through a cutting location, a rotating mass holder for holding and rotating a longitudinally-extending mass of material about its longitudinal axis, and a second drive. The second drive advances the mass holder and/or the wire toward one another to orient the longitudinal axis of the mass of material at the cutting location in a position perpendicular to the wire to cut the mass of material. Other aspects of the invention include a method of cutting, the mass holder per se.

Abstract: An extrusion die is used for producing ceramic honeycomb materials. It is particularly useful in producing such extrudates in sheet form by configuring the die in the form of a cylinder and providing a cutting device proximate to the exterior of the cylinder so that when relative rotation is imparted between the cutter and the cylinder, a honeycomb sheet is removed. A cover can be provided over the exterior surface of the cylindrically-shaped die to permit formation of honeycomb extrudates in pellet form.
