Method and apparatus for laminating toner images on receiving sheets

Claim 3

The method according to claim 1 wherein said receiving sheet is transparent and said toner image is a color toner image.

Claim 4

The method according to claim 2 wherein said receiving sheet and said laminating sheets are the same and are fed from a single stack in said sheet supply.

Claim 5

The method according to claim 3 wherein said sheets have a layer of heat softenable thermoplastic which layers engage the toner image and soften while passing through the fuser, encapsulating the toner image.

Claim 6

The method according to claim 1 wherein said laminating sheet has a layer of heat softenable thermoplastic, which layer engages said toner image and softens while passing through the fuser, encapsulating the toner image.

Claim 7

The method according to claim 1 wherein said receiving sheet and laminating sheet are different and said receiving sheet is fed from a first stack in said sheet supply means containing only receiving sheets and said laminating sheet is fed from a second stack in said sheet supply means containing only laminating sheets.

Claim 8

The method according to claim 1 wherein said receiving sheet and laminating sheet are different and are fed from a single stack in which said sheets are arranged alternatively.

Claim 9

Reproduction apparatus comprising: an image-bearing member, means for forming a series of toner images of different color on said image-bearing member, means for holding a supply of receiving sheets and of transparent laminating sheets, a transfer drum, said transfer drum including means for attaching a receiving sheet to said drum for repeated presentation to said series of toner images of different color to transfer said images to said receiving sheet in registry to form a multicolor toner image on said receiving sheet, means for fusing a toner image to a receiving sheet, means for feeding a receiving sheet through a path from said supply to said transfer drum to receive said multicolor toner image thereon and thereafter to said fusing means, and means for feeding a transparent laminating sheet from said supply into contact with said multicolor toner image on said receiving sheet to form a sandwich with the multicolor toner image between said sheets, and for feeding said sandwich through said fuser to laminate said multicolor toner image between said sheets.

Claim 10

Reproduction apparatus comprising: an image-bearing member, means for forming a series of toner images of different color on said image-bearing member, means for holding a supply of receiving sheets and of transparent laminating sheets, a transfer drum, said transfer drum including means for attaching a receiving sheet to said drum for repeated presentation to said series of toner images of different color to transfer said images to said receiving sheet in registry to form a multicolor toner image on said receiving sheet, means for fusing a toner image to a receiving sheet, means for feeding a receiving sheet through a path from said supply to said transfer drum to receive said multicolor toner image thereon and thereafter to said fusing means, and means for feeding a transparent laminating sheet from said supply into contact with said multicolor toner image on said receiving sheet to form a sandwich with the multicolor toner image between said sheets, and for feeding said sandwich through said fuser to laminate said multicolor toner image between said sheets.

Claim 11

Reproduction apparatus according to claim 8 wherein said means for holding a supply of receiving sheets and of transparent laminating sheets includes at least one supply hopper that can be used to store receiving sheets in a first mode of operation and to store laminating sheets in a second mode operation.

Claim 12

Reproduction apparatus according to claim 8 wherein said means for feeding said transparent laminating sheet includes means for feeding said transparent laminating sheet through at least a portion of the same path as said receiving sheet is fed to said transfer station, and into engagement with said receiving sheet while said receiving sheet is at least partially secured by said transfer drum.

Claim 13

Reproduction apparatus comprising: an image-bearing member, means for forming a toner image on said image-bearing member, means for holding a supply of receiving sheets and of transparent laminating sheets, means for transferring a toner image from said image-bearing member to a receive sheet, means for fusing a toner image to a receiving sheet, means for feeding a receiving sheet through a path from said supply to said transfer means to receive a toner image thereon and thereafter through said fusing means, means for feeding said receiving sheet from said fuser to a position upstream of said transfer station, and means for feeding a transparent laminating sheet into contact with said toner image after said receiving sheet has been returned to said upstream position to form a sandwich with said toner image between said sheets, and for feeding said sandwich back through said path through said fuser to laminate said toner image between said sheets.

Claim 14

Reproduction apparatus comprising: an image-bearing member, means for forming a toner image on said image-bearing member, means for holding a supply of receiving sheets and of transparent laminating sheets, means for transferring a toner image from said image-bearing member to a receive sheet, means for fusing a toner image to a receiving sheet, means for feeding a receiving sheet through a path from said supply to said transfer means to receive a toner image thereon and thereafter through said fusing means, means for feeding said receiving sheet from said fuser to a position upstream of said transfer station, and means for feeding a transparent laminating sheet into contact with said toner image after said receiving sheet has been returned to said upstream position to form a sandwich with said toner image between said sheets, and for feeding said sandwich back through said path through said fuser to laminate said toner image between said sheets.

Claim 15

Apparatus according to claim 11 wherein said means for feeding said receiving sheet to a position upstream includes means for inverting said receiving sheet to position said sheet back in its original path with the toner image on a side of said sheet which side is reversed from its orientation when orginally fed to said transfer station.
