Damped binding apparatus

Claim 3

An apparatus according to claim 1, wherein said supporting means is stationary.

Claim 4

An apparatus according to claim 2, wherein said damping means includes a shock absorber.

Claim 5

An apparatus according to claim 3, wherein said supporting means includes a heated platen defining a generally planar, substantially horizontal support surface.

Claim 6

An apparatus according to claim 4, wherein said moving means includes a tilt bed which is adapted to pivot so as to orient the set of sheets substantially vertically and to move the set of sheets in a downward direction toward said supporting means.

Claim 7

An apparatus according to claim 5, wherein said controlling means includes means for limiting the movement of said moving means to regulate the depth of penetration of said one edge of the set of sheets into the adhesive on the strip.

Claim 8

An apparatus according to claim 6, further including a pair of heated side guides arranged to be normally spaced from the set of sheets and being movable to fold the sides of the strip into contact with opposed outer sheets of the set of sheets and heat the sides of the strip to fix the sides of the strip to the opposed outer sheets of the set of sheets.

Claim 9

An apparatus according to claim 6, wherein said limiting means includes at least one stop for limiting the movement of said moving means.

Claim 10

An apparatus according to claim 8, wherein said stop limits the penetration of said one edge of the set of 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.

Claim 11

An electrophotographic printing machine of the type having a binding apparatus, and in which successive copy sheets having indicia recorded thereon are compiled into sets and advanced to the binding apparatus which binds the sheets of each set together by applying a strip having adhesive on one surface thereof to one edge of the set, wherein the improved binding apparatus includes: means for supporting and heating the strip to soften the adhesive thereon; means for moving said supporting means and the set of copy sheets relative to one another so as to press one edge of the set of copy sheets into the adhesive on the strip; means for controlling 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; and means for damping said moving means to absorb a substantial portion of the kinetic energy of the set of sheets as the set of sheets contacts the adhesive on the strip reducing deflection and distortion of the set of sheets.

Claim 12

An electrophotographic printing machine of the type having a binding apparatus, and in which successive copy sheets having indicia recorded thereon are compiled into sets and advanced to the binding apparatus which binds the sheets of each set together by applying a strip having adhesive on one surface thereof to one edge of the set, wherein the improved binding apparatus includes: means for supporting and heating the strip to soften the adhesive thereon; means for moving said supporting means and the set of copy sheets relative to one another so as to press one edge of the set of copy sheets into the adhesive on the strip; means for controlling 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; and means for damping said moving means to absorb a substantial portion of the kinetic energy of the set of sheets as the set of sheets contacts the adhesive on the strip reducing deflection and distortion of the set of sheets.

Claim 13

A printing machine according to claim 10, wherein said supporting means is stationary.

Claim 14

A printing machine according to claim 11, wherein said damping means includes a shock absorber.

Claim 15

A printing machine according to claim 12, wherein said supporting means includes a heated platen defining a generally planar, substantially horizontal support surface.

Claim 16

A printing machine according to claim 13, wherein said moving means includes a tilt bed which is adapted to pivot so as to orient the set of sheets substantially vertically and to move the set of sheets in a downward direction toward said supporting means.

Claim 17

A printing machine according to claim 14, wherein said controlling means includes 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.

Claim 18

A printing machine according to claim 15, further including a pair of heated side guides arranged to be normally spaced from the set of copy sheets and being movable 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 19

A printing machine according to claim 15, wherein said limiting means includes at least one stop for limiting the movement of said moving means.

Claim 20

A printing machine according to claim 15, wherein said stop limits the penetration of said one edge of the set of 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.
