Abstract
A tape casting machine has a casting base with a feed location lying generally in a horizontal plane, and a casting head positioned to dispense a slurry onto the casting base. The casting base and the casting head are movable relative to each other. The casting head includes a reservoir containing the slurry, and a doctor blade having a lower leading margin contacting the slurry in the reservoir and disposed adjacent to but not contacting the casting base. The slurry exits from the reservoir to the feed location of the casting base between the lower leading margin of the doctor blade and the casting base to form a cast tape. The lower trailing margin of the doctor blade has a curvature in the horizontal plane and/or a vertical plane.
