Abstract:
A pressure sealing apparatus for acting on business forms having pressure activated cohesive to seal the cohesive, said apparatus comprising:first and second pressure-seal rollers rotatable about substantially parallel first and second axes of rotation, respectively, and in operative association with each other so as to define a nip which supplies sufficient pressure so as to activate pressure activated cohesive on a business form passing through said nip; drive means for driving at least one of said pressure-seal rollers to effect movement of a business form completely through said nip; and holding means for holding a business form having pressure activated cohesive in a position distinct from said nip but so that the business form will substantially automatically be engaged by and pass through said nip upon operation of said drive means, wherein said holding means comprises a primarily vertically disposed flip plate positioned with respect to said nip so that the trailing edge of a business form entering the flip plate will ultimately enter said nip and become the leading edge of the business form, wherein said pressure-seal rollers consist essentially of said first and second rollers and a third roller rotatable about a third axis of rotation substantially parallel to said first and second axes of rotation, and in operative association with said first roller so as to define a second nip which supplies sufficient pressure so as to activate pressure activated cohesive on a business form passing through said second nip, and further comprising a business form folder, including a first folder roller rotatable about a fourth axis of rotation substantially parallel to said third axis, and operatively positioned with respect to said third pressure-seal roller and first and second fold plates so that said third roller effects folding of a business form passing between said third pressure-seal roller and said first folder roller, and effects sealing of the business form when passing from said second fold plate through said second nip.
