Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
203 words
Adhesive binding apparatus for edge binding multiple sets of sheet material held in a stack of multiple trays comprising: adhesive application means including a movable adhesive transfer belt having a frontside facing the multiple trays and aligned edges of the multiple sets of sheet material to be bound and a backside, the transfer belt movable between a retracted position out of contact with the edges of the multiple sets of sheet material and an adhesive application position for transfer of adhesive on the belt onto the edges of the sets of the sheet material, an adhesive dispenser for depositing adhesive on the transfer belt, means mounting the belt for transfer between the retracted and the adhesive application positions, a belt aligning bar, and means connected to the belt aligning bar which, when the belt is moved from the retracted position to the adhesive application position, contact the front surface of the trays holding the sets of sheet material to align the belt aligning bar and the frontside run of the belt so that they are parallel to the front surface of the trays and to a plane extending through the edges of each of the multiple sets of sheet material to be bound.
Claim 2
Dependent Claim
203 words
Adhesive binding apparatus for edge binding multiple sets of sheet material held in a stack of multiple trays comprising: adhesive application means including a movable adhesive transfer belt having a frontside facing the multiple trays and aligned edges of the multiple sets of sheet material to be bound and a backside, the transfer belt movable between a retracted position out of contact with the edges of the multiple sets of sheet material and an adhesive application position for transfer of adhesive on the belt onto the edges of the sets of the sheet material, an adhesive dispenser for depositing adhesive on the transfer belt, means mounting the belt for transfer between the retracted and the adhesive application positions, a belt aligning bar, and means connected to the belt aligning bar which, when the belt is moved from the retracted position to the adhesive application position, contact the front surface of the trays holding the sets of sheet material to align the belt aligning bar and the frontside run of the belt so that they are parallel to the front surface of the trays and to a plane extending through the edges of each of the multiple sets of sheet material to be bound.
Claim 3
Dependent Claim
109 words
The adhesive binding apparatus of claim 9, wherein the belt aligning bar extends along a portion of the length of and in contact with the backside of the belt, and wherein the alignment means includes adjustable belt alignment stops positioned along the length of the belt aligning bar and extending beyond the plane of the frontside surface of the transfer belt coated with adhesive, so that when the belt is moved from the retracted position to the adhesive application position the alignment stops contact the front surface of the trays holding the sets of sheet material to center the belt aligning bar and the frontside run of the belt.
Claim 4
Dependent Claim
30 words
The adhesive binding apparatus of claim 2, wherein the belt aligning bar includes heating means therein to maintain the adhesive coated on the transfer belt at a preselected operating temperature.
Claim 5
Dependent Claim
67 words
The adhesive coating apparatus of claim 2, wherein the adjustable belt aligning stops are positioned at spaced intervals along the frontside run of the belt and the stops adjusted so that the frontside run of the belt clears the edges of the sheets to be bound, yet is close enough thereto that adhesive deposited on the transfer belt contacts the edges of the sheets to be bound.
Claim 6
Dependent Claim
69 words
The adhesive binding apparatus of claim 4, wherein the adjustable belt aligning stops are connected to the belt aligning bar and the belt aligning bar is mounted so that when the stops contact the trays the belt aligning bar is automatically positioned to align the belt in contact therewith parallel to the plane extending through the edges of each of the multiple sets of sheet material to be bound.
Claim 7
Dependent Claim
47 words
The adhesive binding apparatus of claim 1, wherein the adhesive belt is fabricated of a non-metallic synthetic fabric having low elongation characteristics, the fabric belt enabling the adhesive to be metered onto the transfer belt at a lower temperature without sacrificing the bonding characteristics of the adhesive.
Claim 8
Dependent Claim
55 words
The adhesive binding apparatus of claim 1, including transfer belt drive means for incrementally advancing the belt between applications of adhesive to the edges of the sets of sheet material to be bound to position fresh portions of adhesive for binding further edges without the necessity of advancing the transfer belt through a complete revolution.
Claim 9
Dependent Claim
42 words
The adhesive binding apparatus of claim 1, wherein the adhesive transfer belt is an endless belt trained about spaced rollers, at least one of such rollers including heating means therein to maintain the adhesive metered onto the belt at a preselected temperature.
Claim 10
Dependent Claim
34 words
The adhesive binding apparatus of claim 1, including means for indexing the adhesive binding apparatus from one binding position to a subsequent binding position to provide the desired length of sheet set bound edges.
