Abstract
Abstract A lamination apparatus is disclosed which includes serially interconnected loading vacuum chamber, press vacuum chamber and an unloading vacuum chamber. An input transport system is positioned within the loading chamber to transport a printed circuit board book therefrom into the press chamber. An output transport system is likewise positioned in the unloading chamber to remove the printed circuit board book from within the press chamber into the unloading chamber for unloading. The loading and unloading vacuum chambers isolate the press positioned within the press chamber from atmospheric pressure as the printed circuit board books sequentially flow through the lamination apparatus.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
171 words
An apparatus for laminating the layers of a book composed of printed circuit layers and adhesive layers, comprising in combination: a loading vacuum chamber, a first press vacuum chamber, and an unloading vacuum chamber serially connected together in such order, adjacent said chambers being isolated from one another by a common wall having an opening therethrough permitting the book to be transported from the preceding to the succeeding adjacent said chambers; door means affixed about said opening in said common walls, said door means comprising means for forming an air-tight seal about said openings; said loading vacuum chamber and said unloading vacuum chamber each comprising an exterior wall having an opening therethrough; a first press having a pair of first platens, said first platens being positioned within said first press vacuum chamber; input transfer means for transporting the book loaded in said loading vacuum chamber into said first press vacuum chamber; and output transfer means for transporting the book from within said first press vacuum chamber into said unloading vacuum chamber.
Claim 2
Independent Claim
171 words
An apparatus for laminating the layers of a book composed of printed circuit layers and adhesive layers, comprising in combination: a loading vacuum chamber, a first press vacuum chamber, and an unloading vacuum chamber serially connected together in such order, adjacent said chambers being isolated from one another by a common wall having an opening therethrough permitting the book to be transported from the preceding to the succeeding adjacent said chambers; door means affixed about said opening in said common walls, said door means comprising means for forming an air-tight seal about said openings; said loading vacuum chamber and said unloading vacuum chamber each comprising an exterior wall having an opening therethrough; a first press having a pair of first platens, said first platens being positioned within said first press vacuum chamber; input transfer means for transporting the book loaded in said loading vacuum chamber into said first press vacuum chamber; and output transfer means for transporting the book from within said first press vacuum chamber into said unloading vacuum chamber.
Claim 3
Dependent Claim
19 words

Claim 4
Dependent Claim
62 words
The apparatus as set forth in claim 2, further comprising a second press vacuum chamber interposed between said first press vacuum chamber and said unloading vacuum chamber, a second press having movable second platens positioned within said second press vacuum chamber, and a press transfer means for transporting the book from said first press vacuum chamber into said second press vacuum chamber.
Claim 5
Dependent Claim
16 words
The apparatus as set forth in claim 1, wherein said first press comprises a hydraulic press.
Claim 6
Dependent Claim
16 words
The apparatus as set forth in claim 3, wherein each said press comprises a hydraulic press.
Claim 7
Dependent Claim
31 words
The apparatus as set forth in claim 1, wherein said input transfer means comprises a pusher assembly for pushing the book from said loading vacuum chamber into said first press chamber.
Claim 8
Dependent Claim
36 words
The apparatus as set forth in claim 1, wheren said output transfer means comprises a puller assembly for engaging the book within said first press vacuum chamber and pulling the book into said unloading vacuum chamber.
Claim 9
Dependent Claim
64 words
The apparatus as set forth in claim 1, wherein said input transfer means comprises a slide slidable to an abutting position with one of said first platens of said first press and means for sliding said slide in said abuting position, to further move a book placed thereon onto the said abutting platen and then to retract said slide into said loading vacuum chamber.
Claim 10
Dependent Claim
65 words
The apparatus as set forth in claim 1, wherein said output transfer means comprises a slide slidable to an abutting position with one of said platens of said press and means for sliding said slide in said abutting position, to further move a book on said platen onto said abutting slide, and then to retract said slide, with the book thereon, into said unloading chamber.
