Description

A Method and Machinery for Making an OutsertField of invention:

[0001] The present invention relates to sheet folding. More specifically, the present invention relates to a method and machinery for making an outsert.Background of the invention:

[0002] A package of medicines includes one or more informational items therein. These informational items include information of the medications printed thereon according to related laws in a specific country. Pharmaceutical inserts & outsorts are some examples of these informational items. The informational item may be attached to a pharmaceutical container or maybe inserted loosely in a cardboard box in which the pharmaceutical container is kept. The informational item can be unfolded by a consumer to read the information printed therein.

[0003] Generally, these informational items / outserts are made on multiple folding machines arranged adjacent to each other. The multiple folding machines are arranged after one another which requires more time to convey an intermediate folded item from one folding machine to another folding machine to make a plurality of folds. And machinery having multiple folding machines require more floor space to set up the complete machinery. Initially, a sheet is fed to the folding machine to make a plurality of parallel folds to obtain a strip. Further, the strip is conveyed towards a plurality of cross-folding machines to make a plurality of cross-folds on the strip to obtain an outsert. The strip is divided into a plurality of virtual segments and conveyed to the plurality of cross-folding machines one after the other to make the plurality of cross-folds for obtaining the outsert.

[0004] Limitations of prior Art: Presently, the methods and machinery implemented to make outserts with multiple cross-folds are adapted tomake cross-folds on the strip only having an even number of virtual segments like ten, fourteen virtual segments or eighteen virtual segments. These methods are not adapted to make the outsert from a strip having an odd number of virtual segments. The existing method to obtain the outsert is described in patent US7896796B2.

[0005] Referring now to figures la, lb, 1c, and Id, patent US7896796B2 describes a method to make an outsert. The method starts with making a plurality of parallel folds on a sheet to obtain a strip (300) having elongated panels. The strip is having open ends (301, 302). Further, the strip (300) is divided into a plurality of virtual segments. Specifically, the strip (300) is first divided into an even number of virtual segments. A first cross-fold (Fl) is made on the strip (300) to obtain a first intermediate folded item (300a) having an upper portion and a lower portion. A length of the upper portion is equal to a length of the lower portion. The first intermediate folded item (300a) has a first open end (303) and a first closed end (304). Therefore, this method is not suitable for making the first cross-fold (Fl) which will obtain the first intermediate folded item (300a) having an unequal length of the upper portion and the lower portion.

[0006] Further, a second cross-fold (F2) is made on the first intermediate folded item (300a) to obtain a second intermediate folded item (300b) having an upper portion and a lower portion. The length of the upper portion is not equal to the length of the lower portion. The second cross-fold (F2) is made from the first open end (303) towards the first closed end (304). The second intermediate folded item (300b) is having a second closed end (305). Furthermore, a third crossfold (F3) is made on the second intermediate folded item (300b) to obtain a third intermediate folded item (300c) having an upper portion and lower portion. The third cross-fold (F3) is made from the second closed end (305) towards the first closed end (304). Similarly, further cross-folds are made on the third intermediate folded item (300c) to obtain an outsert. The detailed method is described in patent US7896796B2. This method is only adapted to make the first cross-fold (Fl) on the strip (300) having an even number of virtual segments and this method is notsuitable to make a plurality of cross-folds on the strip (300) having an odd number of virtual segments.

[0007] Further patent US7896796B2 describes a method to obtain an outsert from a strip having 10 virtual segments or 14 virtual segments. This method is not adapted to make more compact outsert from the strip having more number of virtual segments. Further, this method requires a machinery which is having a greater number of cross-folding machines that consumes more space. Specifically, this method requires the machinery to have four or five cross-folding machines to obtain the outsert.

[0008] Therefore, there is a requirement for a method and machinery for making an outsert which overcomes few or all drawbacks of the existing technologies.Objects of the invention

[0076] In one more embodiment of the invention, the strip (la) is divided into an even number of virtual segments (Pl, P2, . . .PneVen). At step (120), the first cross-fold (Fl) is made on the said strip (la) to obtain the first intermediate folded item (lb) having an upper portion and a lower portion. The upper portion has a length which is equal to a length of the lower portion. The open ends (201, 202) of the strip (la) are overlapping with each other. In alternative embodiment, the upper portion has a length which is unequal to a length of the lower portion. The open ends (201, 202) of the strip (la) are not overlapping with each other.

[0077] The first cross-fold (Fl) forms a first open end (203) and a first closed end (204) of the first intermediate folded item (lb). The first open end (203) includes the open ends (201, 202) of the strip (la), and the first closed end (204) is formed at the first cross-fold (Fl).

[0078] At step (130a), a second cross-fold (F2) is made on the first intermediate folded item (lb) to obtain a second intermediate folded item (1c). The second intermediate folded item (1c) is having an upper portion and a lower portion.

[0079] At step (140a), a third cross-fold (F3) is made on the second intermediate folded item (1c) to obtain a final intermediate folded item (Id). The final intermediate folded item (Id) is having an upper portion and a lower portion. The upper portion has a length which is unequal to a length of the lower portion of the final intermediate folded item (Id). The second intermediate folded item (1c) is folded from the first closed end (204) towards the second closed end (206).

The outsert (le) is having an upper portion and a lower portion. The upper portion has a length which is equal to a length of the lower portion. After making the final cross-fold (F4), the second closed end (206) is overlapped with the third closed end (207). The outsert (le) is having a length (L”), a width (W”) and a thickness. The length (L”) and the width (W”) of the outsert (le) are approximately same as the length (L’) and the width (W’) of one virtual segment of the plurality of virtual segments.
