Abstract
Abstract An apparatus for applying an adhesive-coated cover sheet or lamina to a substrate, such as a particulate or fibrous core, has a pair of substantially parallel surfaces which lie next to each other and form beds for the sheet and the substrate, respectively. Pivoted between these surfaces is a fork which can swing through an arc of close to 180* and has tines for lifting the adhesive-free underside of the sheet so that it can swing this sheet to a position above the substrate. A depositing arrangement is pivotal about an axis close to the fork pivot axis through the balance of the 180* arc so that it receives the sheet from the fork and moves it to immediately adjacent the substrate; the depositing device is displaced transversely to the pivot axis to the side, gently placing the sheet on the substrate. The surface of this placing arrangement is formed by a plurality of parallel cables which are spanned over a transversely displaceable guide.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
149 words
An apparatus for applying a sheet to a substrate, said apparatus comprising: means defining a first surface adjacent the substrate for supporting the sheet; a fork having tines engageable with said sheet and being pivotal about an axis parallel to said first surface and disposed between said first surface and said substrate; means forming a second surface immediately above said substrate; means for pivoting said fork about said axis between a first position with said tines below said first surface and a second position adjacent and above said second surface and thereby picking said sheet up off said first surface, turning it over, and depositing it on said second surface; means for displacing said second surface out from between said substrate and said sheet transversely to said axis to lay said sheet on said substrante; and means for pivoting said second surface about an axis parallel to said substrate.
Claim 2
Independent Claim
149 words
An apparatus for applying a sheet to a substrate, said apparatus comprising: means defining a first surface adjacent the substrate for supporting the sheet; a fork having tines engageable with said sheet and being pivotal about an axis parallel to said first surface and disposed between said first surface and said substrate; means forming a second surface immediately above said substrate; means for pivoting said fork about said axis between a first position with said tines below said first surface and a second position adjacent and above said second surface and thereby picking said sheet up off said first surface, turning it over, and depositing it on said second surface; means for displacing said second surface out from between said substrate and said sheet transversely to said axis to lay said sheet on said substrante; and means for pivoting said second surface about an axis parallel to said substrate.
Claim 3
Dependent Claim
30 words
The apparatus defined in claim 1 wherein said first surface is parallel to said substrate, said means for displacing said second surface including a guide displaceable transversely to said axis.
Claim 4
Dependent Claim
77 words
The apparatus defined in claim 1 wherein said means forming said second surface includEs a plurality of nonrigid elongated elements passing over said guide, each of said elements having one end fixed relative to the substrate and another end displaceable away therefrom, said means forming said second surface also including means connected to said other ends of said elements for making same taut to pull same over said guide on retraction of said guide toward said axis.
Claim 5
Dependent Claim
12 words
The apparatus defined in claim 1 wherein said elements are flexible cables.
Claim 6
Dependent Claim
42 words
The apparatus defined in claim 1 wherein said substrate and said first surface are substantially parallel, said fork being pivotal through a major arc and said second surface being pivotal through a minor arc, said arcs together extending over substantially 180* .
Claim 7
Dependent Claim
17 words
The apparatus defined in claim 1 wherein said major arc extends over between 165* and 170* .
Claim 8
Dependent Claim
21 words
The apparatus defined in claim 1 wherein said means for pivoting said second surface includes at least one upright hydraulic cylinder.
Claim 9
Dependent Claim
25 words
The apparatus defined in claim 1 wherein said means defining said first surface includes a plurality of rollers, said tines being engageable between said rollers.
Claim 10
Dependent Claim
26 words
The apparatus defined in claim 1 further comprising transport means forming a surface receiving said substrate for conveying said substrate into and out of said apparatus.
Claim 11
Independent Claim
85 words
A method of forming a laminate comprising the steps of: advancing a sheet in a transport direction to a position alongside a substrate; pivoting said sheet through an angle between 90* and 180* about an axis substantially parallel to said transport direction and laying said sheet on a surface above said substrate; moving said surface downwardly toward said substrate; and withdrawing said surface out from between said sheet and said substrate in a direction transverse to said axis to deposit said sheet on said substrate.
Claim 12
Independent Claim
85 words
