Abstract
Abstract An apparatus which adhesively binds a set of sheets by applying a strip having an adhesive on one surface thereof to the spine of the set. The strip is supported on a heated platen which softens the adhesive. The spine of the set of copy sheets is pressed into the adhesive on the strip. The depth of penetration of the spine into the adhesive is controlled so as to form a layer of adhesive between the spine and the strip having a predetermined thickness.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
An electrophotographic printing machine of the type in which successive copy sheets having indicia recorded thereon are compiled into sets and the sheets of each set are bound together by applying a strip having adhesive on one surface thereof to one edge of the set, wherein the improvement includes: means for stationarily supporting and heating the strip to soften the adhesive thereon; means for moving the set of copy sheets relative to said supporting means so as to press one edge of the set of copy sheets into the adhesive on the strip; and means for limiting the movement of said moving means to regulate the depth of penetration of said one edge of the set of copy sheets into the adhesive on the strip so as to form a layer of adhesive between said one edge of the set and the strip having a predetermined thickness.
Claim 2
Dependent Claim
147 words
An electrophotographic printing machine of the type in which successive copy sheets having indicia recorded thereon are compiled into sets and the sheets of each set are bound together by applying a strip having adhesive on one surface thereof to one edge of the set, wherein the improvement includes: means for stationarily supporting and heating the strip to soften the adhesive thereon; means for moving the set of copy sheets relative to said supporting means so as to press one edge of the set of copy sheets into the adhesive on the strip; and means for limiting the movement of said moving means to regulate the depth of penetration of said one edge of the set of copy sheets into the adhesive on the strip so as to form a layer of adhesive between said one edge of the set and the strip having a predetermined thickness.
Claim 3
Dependent Claim
23 words
A printing machine according to claim 1, wherein said supporting means includes a heated platen defining a generally planar, substantially horizontal support surface.
Claim 4
Dependent Claim
30 words
A printing machine according to claim 2, wherein said moving means orients the set of copy sheets substantially vertically and moves the set of copy sheets in a downward direction.
Claim 5
Dependent Claim
73 words
A printing machine acording to claim 12, further including a pair of heated side guides arranged to be normally spaced from the set of copy sheets and being mvoable to fold the sides of the strip into contact with opposed outer sheets of the set of copy sheets and heat the sides of the strip to fix the sides of the strip to the opposed outer sheets of the set of copy sheets.
Claim 6
Dependent Claim
24 words
A printing machine according to claim 4, wherein said limiting means includes at least one stop for limiting the movement of said moving means.
Claim 7
Dependent Claim
52 words
A printing machine according to claim 5, wherein said stop limits the penetration of said one edge of the set of copy sheets into the adhesive of the strip so that the layer of adhesive between said one edge of the set and the strip has a thickness of about 0.254 millimeters.
