Abstract
Abstract There is disclosed an apparatus for producing a bilayered green ceramic tape having a corrugated first layer and a substantially flat second layer bonded thereto. The apparatus comprises a first supply means for supplying a substantially flat pliable first layer, a forming means for forming said first layer with a corrugated cross section, a drive means associated with the forming means for providing relative movement thereto, a second supply means for supplying a substantially flat pliable second layer of material, and a bonding means for bonding the first and second layers. A method for producing the above described ceramic tape is also disclosed.

AN APPARATUS FOR PRODUCING A BILAYERED GREEN CERAMIC TAPE HVING A CORRUGATED FIRST LAYER AND A SUBSTANTIALLY FLAT SECOND LAYER BONDED THERETO, SAID APPARATUS COMPRISING: FIRST SUPPLY MEANS FOR SUPPLYING A SUBSTANTIALLY FLAT PLIABLE FORST LAYER OF GREEN CERAMIC MATERIAL TO SAID APPARATUS FORMONG MENS FOR FORMING SAID FIRST LAYER WHEREBY SAID FIRST LAYER IS PROVISED WITH A CORRUGATED CROSS SECTION SAID FORMING MEANS COMPRISING A RIBBED ROTABLE CYLINDER AND A RIBBED BELT MEMBER ADAPTED FOR EXTENDING PRESSURE AGAINST SAID CYLINDER SAID CYLINDER AND BELY MEMBER ENGAGING SAID FIRST LAYER AND PASSING SAID FIRST LAYER THEREBETWEEN FOR A PREDETERMINED PERIOD OF TIME WHEREBY SAID FIRST LAYER WILL ENGAGE A SUBSTANTIAL PORTION OF THE OUTER RIBBED PORTION OF SAID ROTABLE CYLINDER, SOLVENT DIPENSING MEANS ADAPTED FOR APPLYING AN ORGANIC SOLVENT TO THE SURFACE OF SAID SUBSTINTIALLY FLAT FIRST LAYER WHICH ENGAGES SAID RIBBED BELT MEMBER PRIOR TO SAID ENGAGEMENT, DRIVE MEANS ASSOCIATED WITH SAID BELT MEMBER OF SAID FORMING MEANS FOR PROVIDING RELATIVE MOVEMENT THERETO, SECOND SUPPLY MEANS FOR SUPPLYING A SUBSTANTIALLY FLAT PLIABLE SECOND LAYER OF GREEN CERAMIC MATERIAL TO SAID APPARATUS, AND BONDING MEANS ADAPTED FOR POSITIONING AND BOILING A FIRST SURFACE OF SAID FLAT SECOND LAYER TO A FIRST SIDE OF SAID CORRUGATED FIRST LAYER.
Claim 3
Dependent Claim
75 words
The apparatus according to claim 1 wherein said bonding means comprises a pressure exerting means positioned relative to said drive means, said pressure exerting means adapted for positioning a first surface of said substantially flat second layer on a first side of said corrugated first layer and for exerting a predetermined amount of pressure against said positioned second layer as said first and second layers pass between said pressure exerting means and said drive means.
Claim 4
Dependent Claim
46 words
The apparatus according to claim 2 wherein said pressure exerting means comprises a rotatable cylinder aligned with and positioned substantially above said drive means, said rotatable cylinder having a spring means associated therewith adapted for exerting downward pressure on said rotatable cylinder against said second layer.
Claim 5
Dependent Claim
40 words
The apparatus according to claim 2 including a solvent dispensing means adapted for applying an organic solvent to said first surface of said second layer prior to positioning said first surface on said first side of said corrugated first layer.
Claim 6
Dependent Claim
38 words
The apparatus according to claim 2 including a heater means for heatiNg said first and second layers to a preestablished temperature prior to passing said first and second layers between said pressure exerting means and said drive means.
Claim 7
Dependent Claim
36 words
The apparatus according to claim 1 including a heater means for heating said first and second layers to a preestablished temperature prior to bonding said first surface of siad second layer to said corrugated first layer.
Claim 8
Dependent Claim
41 words
The apparatus according to claim 6 including a solvent dispensing means adapted for applying an organic solvent to said first surface of said flat second layer prior to positioning said first surface on said first side of said corrugated first layer.
Claim 9
Dependent Claim
27 words
The apparatus according to claim 1 including an adjustment means for adjusting the amount of pressure exerted by said ribbed belt member against said ribbed rotatable cylinder.
