Abstract: This invention concerns an improved gluing machine and a continuous method of operation which allows the gluing process to proceed at a rate that equals the feed rate of vacuum rotary document feeders. The machine includes a unique registry and guide system for efficiently moving documents fed initially in an individual manner in a continuous, flowing manner from an initial input feed device to the gluing and registry point with the carrier. The feed system not only allows substantially greater operating speeds but simultaneously overlaps documents while establishing and maintaining correct registration of the documents. The documents are overlapped so that following documents are positioned beneath leading documents. This overlapped condition together with the registry achieved within the feed system assures each individual document arrives in proper registry with areas of glue previously applied at preselected intervals on the carrier sheet.

Abstract: A novel carrier sheet and envelope arrangement comprised of a highly segmented carrier sheet on which envelopes are held in a closed, prefolded condition which allows use of shorter lengths of carrier sheeting for holding comparable qualities of envelopes or other business forms than has heretofore been the case. The carrier sheet and envelope arrangement also allows the envelopes to be removed from the carrier sheet either by hand or automatically by machine.
