Claims
- 1. An apparatus for slitting ceramic green sheets comprising,
- (a) a slitting mechanism having at least one slitting wheel,
- (b) moving means for bringing at least one layer of ceramic green sheet underneath said at least one slitting wheel, wherein at least a portion of said at least one layer of ceramic green sheet is slit by said at least one slitting wheel,
- (c) wherein said apparatus has at least one back-up roller which provides a counter-pressure to said at least one layer of said ceramic green sheet when said at least one layer of said ceramic green sheet is slit by said at least one slitting wheel, and
- (d) wherein said slitting mechanism is inside an oven and secured thereto.
- 2. The apparatus of claim 1, wherein said slitting wheel is designed to slit a ceramic green sheet selected from a group consisting of uncured ceramic material, semi-cured ceramic material and cured ceramic material.
- 3. The apparatus of claim 1, wherein at least a portion of an edge of said slitting wheel has a flat surface.
- 4. The apparatus of claim 1, wherein said slitting mechanism has at least one means to adjust a slitting height of said at least one slitting wheel.
- 5. The apparatus of claim 1, wherein said slitting mechanism has at least one means to adjust a toe of said at least one slitting wheel.
- 6. The apparatus of claim 1, wherein said at least one layer of ceramic green sheet is on a carrier.
- 7. The apparatus of claim 6, wherein said carrier is selected from a group consisting of polyethylene and polyethylene terephthalate material.
- 8. The apparatus of claim 1, wherein said oven has a plurality of heating zones.
- 9. The apparatus of claim 8, wherein said slitting mechanism inside said oven is in one of said heating zones.
- 10. An apparatus for slitting ceramic green sheets comprising,
- (a) a hopper adapted to contain ceramic slurry,
- (b) means for feeding a supporting sheet underneath said hopper,
- (c) means associated with said hopper to form a layer of said ceramic slurry onto said supporting sheet, and forming at least one layer of ceramic green sheet,
- (d) a slitting mechanism having at least one slitting wheel,
- (e) moving means for bringing said at least one layer of ceramic green sheet underneath said at least one slitting wheel, wherein at least a portion of said at least one layer of ceramic green sheet is slit by said at least one slitting wheel, and
- (f) wherein said slitting mechanism is inside an oven and secured thereto.
- 11. The apparatus of claim 10, wherein said slitting wheel is designed to slit a ceramic green sheet selected from a group consisting of uncured ceramic material, semi-cured ceramic material and cured ceramic material.
- 12. The apparatus of claim 10, wherein at least a portion of an edge of said slitting wheel has a flat surface.
- 13. The apparatus of claim 10, wherein said slitting mechanism has at least one means to adjust a slitting height of said at least one slitting wheel.
- 14. The apparatus of claim 10, wherein said slitting mechanism has at least one means to adjust a toe of said at least one slitting wheel.
- 15. The apparatus of claim 10, wherein said at least one layer of ceramic green sheet is on a carrier.
- 16. The apparatus of claim 15, wherein said carrier is selected from a group consisting of polyethylene and polyethylene terephthalate material.
- 17. The apparatus of claim 10, wherein said oven has a plurality of heating zones.
- 18. The apparatus of claim 17, wherein said slitting mechanism inside said oven is in one of said heating zones.
