Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
An apparatus for gluing together a plurality of sheets having intersecting leading edges and binding edges, comprising: means for clamping the binding edges of the sheets together such that they are in coincidence with a first plane and the leading edges are in alignment with one another; means for advancing the binding edges in the first plane; adhesive applicator means displaceable between spaced positions and yieldably biased in a first position to present a surface thereof into substantial coincidence with the first plane at a point in the travel of the binding edges; and, first and second cooperating cam means, said first cam means located on said clamping means and said second cam means located on said adhesive applicator means, said cooperating cam means being relatively engageable to displace said adhesive applicator means relatively away from the first plane against the bias thereon when the leading edges of the sheets approach said point in the direction of travel, and relatively disengageable when the leading edges have passed said point in the direction of travel.
Claim 2
Independent Claim
174 words
An apparatus for gluing together a plurality of sheets having intersecting leading edges and binding edges, comprising: means for clamping the binding edges of the sheets together such that they are in coincidence with a first plane and the leading edges are in alignment with one another; means for advancing the binding edges in the first plane; adhesive applicator means displaceable between spaced positions and yieldably biased in a first position to present a surface thereof into substantial coincidence with the first plane at a point in the travel of the binding edges; and, first and second cooperating cam means, said first cam means located on said clamping means and said second cam means located on said adhesive applicator means, said cooperating cam means being relatively engageable to displace said adhesive applicator means relatively away from the first plane against the bias thereon when the leading edges of the sheets approach said point in the direction of travel, and relatively disengageable when the leading edges have passed said point in the direction of travel.
Claim 3
Dependent Claim
46 words
An apparatus of claim 1, wherein said adhesive applicator means includes an adhesive reservoir, and a rotatable drum mounted therein, said rotatable drum having a peripheral surface which is in substantial coincidence with the plane when the adhesive applicator means is biased in the first position.
Claim 4
Dependent Claim
58 words
An apparatus of claim 2, wherein said first cam means projects forward of said clamping means and said leading edges in the direction of travel thereof, and wherein said second cam means is located substantially in a second plane located substantially at right angles to the first plane and passing through said point in the direction of travel.
Claim 5
Dependent Claim
25 words
An apparatus of claim 2, including means to rotate said drum in a direction opposite to that of the direction of travel of said sheets.
Claim 6
Dependent Claim
38 words
An apparatus of claim 1, wherein said adhesive applicator means is pivotable about an axis spaced away from said point and substantially in the first plane, and is yieldably biased to be in equilibrium in said first position.
Claim 7
Dependent Claim
15 words
An apparatus of claim 5, including a spring for yieldably biasing said adhesive applicator means.
