ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention is directed to a method and machine for forming informational items such as outserts.
An outsert is an informational item formed from a sheet of paper which is folded in two perpendicular directions. The sheet of paper has information printed thereon, which is typically information relating to a pharmaceutical product or drug. The outsert may be adhesively attached to the top or side of a pharmaceutical container, such as a bottle of pills. Alternatively, the outsert may be inserted loosely into a cardboard box in which a pharmaceutical container is disposed. After purchase of the pharmaceutical product by a consumer, the outsert may be unfolded so that the consumer may read the information printed thereon.
There are a number of patents which disclose methods of forming outserts and machines that may be used in connection with the formation of outserts. For example, U.S. Pat. No. 4,616,815 to Michael Vijuk discloses an automatic stacking and folding apparatus. U.S. Pat. No. 4,812,195 to Michael Vijuk discloses various methods and apparatus for forming outserts. U.S. Pat. No. 4,817,931 to Robert Vijuk discloses a method and apparatus for forming a folded leaflet. U.S. Pat. No. 5,044,873 to Michael Vijuk discloses an apparatus for stacking folded sheets on edge. U.S. Pat. Nos. 5,458,374, 5,813,700 and 5,909,899 disclose various methods of forming outserts.
A prior art outsert-forming machine sold by the assignee of this patent more than one year prior to the effective filing date of this patent included a first folding unit that formed a first folded article from a sheet of paper having printed information thereon by making a plurality of folds in the sheet of paper, each of the folds being parallel to a first direction, a second folding unit operatively coupled to receive the first folded article that formed a second folded article by making a fold in the first folded article in a direction parallel to a second direction perpendicular to the first direction, an adhesive applicator that applied adhesive to a portion of the second folded article, and a final folding unit operatively coupled to receive the second folded article that formed an outsert from the second folded article by making a final fold parallel to the second direction, the final fold being made so that the adhesive held the outsert in a substantially closed position so that the outsert had no exposed unfolded exterior edges in a direction parallel to the final fold.
The first and second folding units of the prior art outsert-forming machine were substantially the same as the folding unit shown in
FIG. 12
of U.S. Pat. No. 4,817,931 to Vijuk and included two frame members, a first pair of folding rollers rotatably mounted between the frame members, a first stop member associated with the first pair of folding rollers that was positioned to cause a leading edge of the sheet of paper to contact the first stop member so that continued feeding of the sheet of paper with the leading edge of the sheet of paper in contact with the first stop member caused an intermediate portion of the sheet of paper to buckle and be passed between the first pair of folding rollers to make a first fold in the sheet of paper, a second pair of folding rollers rotatably mounted between the frame members, and a second stop member associated with the second pair of folding rollers. The second stop member and the second pair of folding rollers were positioned to cause a leading portion of the sheet of paper to contact the second stop member so that continued feeding of the sheet of paper with the leading portion of the sheet of paper in contact with the second stop member caused an intermediate portion of the sheet of paper to buckle and be passed between the second pair of folding rollers to make a second fold in the sheet of paper parallel to the first fold. The operation of the first and second folding units of the prior art outsert-forming machine was the same as the operation of the folding units

shown in
FIGS. 10A-11B
, respectively, of this patent.
The final folding unit of the prior art outsert-forming machine was substantially the same as the folding unit shown in
FIGS. 26-30
of U.S. Pat. No. 4,812,195 to Vijuk and included a pair of frame members, a first folding roller mounted between the frame members, a second folding roller disposed adjacent the first folding roller, the first and second folding rollers having a nip therebetween, the first and second folding rollers causing the final fold to be made when the second folded article passed between the first and second folding rollers, and a movable member that made contact with a portion of the second folded article to move the portion of the second folded article towards the nip between the first and second folding rollers of the final folding unit. The position of one of the two folding rollers of the final folding unit of the prior art outsert-forming machine was adjustable so that the maximum distance between the outer diameters of the folding rollers was 0.22 inches.
SUMMARY OF THE INVENTION
In one aspect, the invention is directed to a method of forming an outsert having product information printed thereon. The method may comprise (a) making a first fold in a first direction in a sheet of paper having product information printed thereon with a first folding apparatus by a method including (a1) feeding a sheet of paper having a leading edge, a trailing edge, and product information printed thereon into the first folding apparatus until the leading edge of the sheet of paper makes contact with a first stop member of the first folding apparatus, (a2) continuing to feed the sheet of paper through the first folding apparatus with the leading edge of the sheet of paper in contact with the first stop member of the first folding apparatus so that an intermediate portion of the sheet of paper between the leading edge and the trailing edge forms a buckled portion, and (a3) continuing to feed the sheet of paper through the first folding apparatus to cause the buckled portion of the sheet of paper to pass between a first pair of folding rollers of the first folding apparatus to form a first fold in the sheet of paper in the first direction.
The method may also comprise (b) making at least one additional fold in the sheet of paper in a direction parallel to the first fold and the first direction with the first folding apparatus to form a first folded article having a leading edge and a trailing edge by a method including (b1) continuing to feed the sheet of paper through the first folding apparatus until a leading portion of the sheet of paper coinciding with the first fold makes contact with a second stop member of the first folding apparatus, (b2) continuing to feed the sheet of paper through the first folding apparatus with the leading portion of the sheet of paper in contact with the second stop member of the first folding apparatus so that an intermediate portion of the sheet of paper between the leading portion and the trailing edge of the sheet of paper forms a buckled portion, and (b3) continuing to feed the sheet of paper through the first folding apparatus to cause the buckled portion between the leading portion of the sheet of paper and the trailing edge of the sheet of paper to pass between a second pair of folding rollers of the first folding apparatus to form a second fold in the sheet of paper in the first direction.
The method may further comprise (c) making a first fold in the first folded article in a second direction perpendicular to the first direction with a second folding apparatus by a method including (c1) feeding the first folded article into the second folding apparatus until the leading edge of the first folded article makes contact with a first stop member of the second folding apparatus, (c2) continuing to feed the first folded article through the second folding apparatus with the leading edge of the first folded article in contact with the first stop member of the second folding apparatus so t
