Abstract

Abstract There is disclosed an addressing system including an addressing apparatus and addressing methods and materials used therein. A set of master cards is provided formed of porous tab card stock impregnated with a sensitizer vaporizable at 100* to 160* C. and having a selected area on one face thereof for the address in infrared absorbing ink; as disclosed, the master card is made by passing the porous tab card stock through a bath containing the sensitizer and a solvent therefor, after which the solvent is evaporated. The set of master cards is then employed to provide a master tape that is a strip of non-porous release material that is oleophobic and transparent to infrared radiation, and carrying thereon reverse reading copies of the addresses in the form of bodies of partially fused toner applied to one side of the master tape; the addresses are transferred from the master cards to the master tape utilizing a novel apparatus and method wherein a printing station is provided having a first source of infrared radiation thereat, first feed mechanism for feeding the master cards sequentially to the printing station and a second feed mechanism for feeding the master tape to the printing station to position a predetermined portion of the master tape immediately adjacent to the address on a master card positioned at the printing station, thereafter operating the first source of infrared radiation to vaporize from the master card sensitizer in areas corresponding to the address thereon onto the one surface of the master tape, applying a toner to the master tape to adhere toner to the sensitizer in areas corresponding to the address, and thereafter exposing the master tape carrying the powdered toner to a second source of infrared radiation for at least partially fusing the toner to provide a reverse reading copy of the address on the master tape. The toner comprises a vehicle body of wood resin and polymerized resin, modifiers of polyamide resin and a hydrocarbon resin and pigment of carbon black. The master tape with the addresses thereon in partially fused toner is then fed to an addressing station where an envelope or other article to be addressed is placed with the surface thereof against the partially fused toner on a section of the master tape after which heat and pressure are applied thereto to transfer the bodies of toner to the envelope and fully to fuse the toner to provide on the envelope bodies of fully fused toner in areas corresponding to the address on a master card.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 95 words
The apparatus set forth in claim 1, and further comprising a third feed mechanism for feeding receptor sheets sequentially to position a receptor sheet against the bodies of toner on the master tape corresponding to the indicia on a master card, and means for applying heat and pressure to the master tape and the receptor sheet to transfer the bodies of toner to the receptor sheet and fully to fuse the toner thereby to provide on the receptor sheet bodies of fully fused toner in an area corresponding to the indicia on a master card.
Claim 2
Dependent Claim 33 words
The apparatus set forth in claim 2, wherein said means for applying heat and pressure to the master tape and the receptor sheet applies a pressure at a temperature above about 225* F.
Claim 3
Independent Claim 294 words
An apparatus for transferring indicia from a group of master cards onto a master tape, wherein each master card has thereon indicia of infrared absorbing material and vaporizable material in the area of the indicia, and wherein the master tape has a non-porous oleophobic surface having resin release characteristics and is transparent to infrared radiation, said apparatus comprising a printing station having a first source of infrared radiation thereat, a first feed mechanism for feeding the master cards sequentially to said printing station to position a master card with the indicia thereon in position to be exposed to said first source of infrared radiation, a second feed mechanism for feeding the master tape to said printing station to position a predetermined portion of the master tape with one surface thereof disposed immediately adjacent to the indicia on a master card positioned at said printing station, means for operating said first source of infrared radiation after feeding of a master card and a predetermined portion of the master tape to said printing station to vaporize from the master card a portion of the vaporizable material from areas corresponding to the indicia thereon onto the one surface of the predetermined portion of the master tape to provide on the master tape vaporizable material arranged in areas corresponding to the indicia, means for applying a toner to the one surface of the master tape thereby to adhere toner to the vaporizable material thereon in areas corresponding to the indicia, and a second source of infrared radiation for at least partially fusing the toner on the master tape, thereby to provide a continuous master tape having on the predetermined portions thereof bodies of partially fused toner in areas corresponding to the indicia on the group of master cards.
Claim 4
Dependent Claim 56 words
The apparatus set forth in claim 4, wherein said first feed mechanism stops the master card at said printing station and said second feed mechanism stops said master tape at said printing station, the master card and the master tape at the printing station being stationary during the operation of said first source of infrared radiation.
Claim 5
Dependent Claim 39 words
ThE apparatus set forth in claim 4, wherein the side of the master card carrying the indicia is in contact with the adjacent one surface of the master tape during the operation of said first source of infrared radiation.
Claim 6
Dependent Claim 99 words
The apparatus set forth in claim 4, and further comprising a third feed mechanism for feeding receptor sheets sequentially to position a receptor sheet against the bodies of partially fused toner on the master tape corresponding to the indicia on a master card, and means for applying heat and pressure to the master tape and the receptor sheet to transfer said bodies of partially fused toner to the receptor sheet and fully to fuse said toner thereby to provide on the receptor sheet bodies of fully fused toner in an area corresponding to the indicia on a master card.
Claim 7
Independent Claim 296 words
An apparatus for transferring addresses from a group of master cards onto a master tape, wherein each master card has thereon an address in infrared absorbing material and vaporizable sensitizer in the area of the address, and wherein the master tape has a non-porous oleophobic surface having resin release characteristics and is transparent to infrared radiation, said apparatus comprising a printing station having a first source of infrared radiation thereat, a first feed mechanism for feeding the master cards sequentially to said printing station to position a master card with the address thereon in position to be exposed to said first source of infrared radiation, a second feed mechanism for feeding the master tape to said printing station to position a predetermined portion of the the master tape with one surface thereof disposed immediately adjacent to the address on a master card positioned at said printing station, means for operating said first source of infrared radiation after feeding of a master card and a predetermined portion of the master tape to said printing station to vaporize from the master card a portion of the vaporizable sensitizer from areas corresponding to the address thereon onto the one surface of the predetermined portion of the master tape to provide on the master tape a film of sensitizer arranged in areas corresponding to the address, means for applying a toner to the one surface of the master tape thereby to adhere toner to the sensitizer thereon in areas corresponding to the address, and a second source of infrared radiation for at least partially fusing the toner on the master tape, thereby to provide a continuous master tape having on predetermined portions thereof bodies of partially fused toner in areas corresponding to the addresses on the group of master cards.
