M \s 6 J7 CONTINUOUS SELF-SEALING ADHESIVE FORMS ESPECIALLY FOR FORMING BOOKLETS This invention relates generally to continuous selfsealing adhesive forms, and more particularly to such forms comprised of detachable form units which may be respectively stacked on one another without s'elfadhering but which may be respectively folded and/or stacked between webs and thereafter slit for the formation of booklets and the like.

In the formation of books and booklets of especially detachable coupons, staples or other fasteners commonly used of different sizes, shapes and strengths are required depending on the number and sizes of sheets per booklet. The drawbacks are apparent when considering the need for stocking a large variety of such fasteners. Moreover, it becomes tedious and timeconsuming and oftentimes amounts to a large waste of fasteners when other than a consistent number of sheets are to be fastened together.

Adhesive of the commonly known self-sealing or drysealing type is herein used for securing the sheets together to form booklets. Such adhesive is such that, when dry, it will adhere only to itself. Other self-sealing adhesives of common usage are those which adhere only to themselves upon impact, upon squeeze or pressure, and those which self-adhere upon heating. Lines of such adhesive are provided along continuous webs comprising detachable form units so that, when the adhesive lines are out of contact with each other in a stacked or storage rolled condition of the webs and/or detached units, self-sealing is avoided. Those heat bonding adhesives referred to also avoid self-sealing even in heated environments and during extended storage periods. On the other hand, when the lines of adhesive are placed in registry with one another, self-sealing is effected (with heat applied when necessary) so that the detachable form units can be formed into booklets. This constitutes the principal object of the invention.

Another object of the invention is to provide at least a pair of continuous forms each comprised of a succession of detachable form units having lines of selfsealing adhesive thereon which, when the continuous forms are rolled up or when the detached units of the respective forms are stacked, the lines of adhesive are out of registry to thereby avoid sticking. However, the lines of adhesive of the detachable units on one form or between forms are registrable for self-sealing to thereby form any number of interconnected booklet sheets.

Another object of the present inven ion is to provide such forms of the character described wherein lines of self-sealing adhesive are formed on the top surface of one form which are offset from the lines of adhesive provided on the bottom surface thereof, and wherein lines of adhesive are formed on at least one of the surfaces of another form in such a manner as to be aligned with the lines of adhesive on one of the surfaces of the one form.

A further object of the invention is to provide such continuous webs wherein the form units may be quickly and easily separated and folded or stacked for selfadhering to produce a booklet or similar product in a I conjunction with the accompanying drawings wherein: FIGS. 1 and 2 are respectively plan views showing portions of two continuous webs used in carrying out the invention;

FIGS. 3 and 4 are sectional views of the webs taken respectively along lines 3-3 and 44 of FIGS. 1 and FIG. 5 is a plan view of a portion of another continuous form used in carrying out the invention;

FIG. 6 is a sectional view of the form taken along line 6-6 of FIG. 5;

FIG. 7 is an end view of a pair of stacked form units of FIG. 1;

FIG. 8 is an expanded perspective view of an assembly of the FIGS. 1, 2 and 5 forms used in carrying out the invention;

FIG. 9 is an end view of the assembly of FIG. 8 showing the units interconnected and spaced apart for clar- FIG. 10 is an expanded perspective view of an assembly of one of the FIGS. 1 and 2 forms together with the FIG. 5 form used in carrying out the invention; and

FIG. 11 is an end view of the assembly of FIG. 10 showing the units interconnected and spaced apart for clarity.

Turning now to the drawings wherein like reference characters refer to like and corresponding parts throughout the several views, a continuous web 10 as shown in FIG. 1 has parallel marginal edges 11 and 12 and a longitudinal fold line 13 along its center. Equally spaced transverse lines of weakening 14 are provided along the web to define a succession of form units 15 of the same size which are detachable along these transverse lines of weakening. Spaced feed holes 16 are provided near each marginal edge 11 and 12, or along one marginal edge only if desired, to facilitate feeding the form through a printer for the application of indicia on one and/or the other surface of the detachable form units in succession.

Referring also to FIG. 3, narrow and continuous lines 17 and 18 of self-sealing adhesive are provided along top surface 19 of web 10 between feed holes 16 and marginal edges 11 and 12, respectively. In a similar manner, lines 21 and 22 of self-sealing adhesive are provided along bottom surface 23 of web 10 respectively inwardly of the two sets of feed holes 16. Longitudinal tear lines 24 are respectively located along the web inwardly of lines 21 and 22 of adhesive and parallel to their respective marginal edges 11 and 12.

Continuous web 25 of FIG. 2 is similar in many respects to the construction of web 10, and like elements are designated by an additional reference letter a. Therefore, parallel marginal edges 11a and 12a define detachable form units 15a together with transverse lines 14a of weakening provided along the form, longitudinal center line 13a and feed holes being provided in a manner similar to that described for web 10. The principal difference in the formation of this web is that lines 17' and 18 of self-sealing adhesive formed along top surface 19a of the web are respectively located inwardly of feed holes 16a as shown in FIGS. 2 and 4. Also, lines 21 and 22 of self-sealing adhesive, which are formed along bottom surface 230 of the web, are located adjacent their respective marginal edges 11a and 12a outwardly of the sets of feed holes 160. By comparison, web 25 is a mirror image" of the construction of web 10. The indicia applied successively on units 15a is, however, similarly carried out as that described for units 15 of web 10. Lines 17' and 18 are respectively spaced equally from center line 13a as are lines 21 and 23 which spacing is identical to that for lines 17 and 18'. Likewise, lines 21" and 22' are respectively spaced the same distance from center line 13a as are lines 17 and 18, and the spacing of these lines for both forms is identical.

Another web 26, formed of a succession of detachable form units used as cover sheets for the booklets assembled of units 15 and/or 15a, has parallel marginal edges 27 and 28, and a longitudinal fold line 29 along its center (see FIG. Spaced transverse lines 31 of weakening are provided along this web to define a succession of form units 32 of equal size to that of form units 15 and 15a. In referring also to FIG. 6, it can be seen that lines 33 and 34 of adhesive are provided along bottom surface 35 of the web at a spacing from their respective marginal edges equal to lines 17, 18 and 21', 22, or alternatively equal to lines 21, 22 and 17', 18. These lines 33 and 34 of adhesive may likewise be alternatively provided along top surface 36 of web 26 with the same spacing as that described when provided along the bottom surface thereof, depending upon whether units 30 are to be used as top or bottom sheets for the booklets.

With the offset relationship of the aforedescribed lines of adhesive on each of the webs 10, 25 and 26, the detached form units of these respective webs can be stacked on top of one another in a stored condition as shown for example in FIG. 7 wherein the detached units 15 of web are shown stacked with lines 17, 18, 21 and 22 in contact only with some portion of the web rather than with another line of adhesive. The stacking is carried out, of course, with the top surface of one form facing the bottom surface of its adjacent form unit. Separation of units a from web and separation of units from web 26 may likewise be respectively stacked in a stored condition without the units sticking to one another.

Webs, 10, 25 and 26 may also be respectively rolled in their stored condition without the likelihood of any of the successive form units thereof sticking to one another.

When it is desired to form a booklet of coupons or the like, form units 15, 15a and 30 may be separated from their respective webs and collated in a manner as shown in FIG. 8. It can therefore be seen that the inner sheets of the booklet are formed by units 15 and 15a, and that the outer cover sheets are formed by the detached units 30. This collating may take place after these form units are separated from their respective webs, or the collating may take place before the form units are so detached. In any event, lines 33 and 34 of adhesive of outer cover units 30 are respectively placed in registry with lines 17 and 18 of adhesive on units 15, and in registry with lines 22' and 21' of adhesive on units 15a. Further, lines 21 and 22 of adhesive of form units 15 are respectively placed in registry with lines 17' and 18' of adhesive of form units 150. Such a registration effects a self-sealing between the various units collated in a manner shown in FIG. 8. Thereafter, the collated form units may be slit along coincident center lines 29, 13 and 13a so as to be separated into two coupon books each having outer cover sheets and four inner sheets removable along their respective tear lines 24 and 24a. A typical booklet 37 is shown in FIG. 9

with the above-described registered lines of adhesive between form units now offset from one another between the top and bottom sheets. Such an offset relation between registered lines of adhesive offers another advantage of avoiding a concentration of adhesive lines directly above one another. Book 37 is therefore rendered not quite as thick as would be the case if the registered lines of adhesive were all aligned.

In lieu of collating the form units as aforedescribed, one or the other of form units 15, 15a may be used together with a form unit 30 in forming a booklet as in the manner shown in FIG. 10. In this example, two form units 15 are used with one form unit 30 in forming a sixply booklet by folding each form unit 15 about its respective center line 13. In such manner, lines 21 and 22 of adhesive of both units are placed in registry with one another, and lines 17 and 18 between form units are likewise placed in such registry. Thereafter, form unit 30 is folded about its center line 29 and completely over the top and bottom of the folded form units 15 so that lines 33 and 34 are placed in registry respectively with lines 17 and 18 of the already folded form units 15. Unit 30 is shown in FIG. 10 broken away in the interest of clarity. After such folding operation is completed, the folded form units may be slit or otherwise separated along respective fold lines 13 and 29. It should be noted that a similar booklet can be formed using form units 15a together with a form unit 30. For such an operation, lines 33 and 34 of adhesive on form unit 30 would be located inwardly of one another from that shown in FIG. 6 so as to be placed respectively in alignment with lines 17' and 18 of adhesive. Otherwise, units 15a would need to be folded so that its top surface would be inside the folded unit. In any case, a booklet 38 is formed as shown in FIG. 11 after the folded units are slit along their center lines as aforedescribed. This booklet is identical to booklet 37 in that the registered lines of adhesive are offset from one another.

From the foregoing, it can be seen that a simple, yet effective and highly economical manner of securing together sheets to form booklets has been devised simply with the use of a self-sealing adhesive located along narrow lines and staggered between the top and bottom surfaces of webs 10 and 25 so that a flat stacking of detached form units of these webs respectively on top of each other in a top surface-to-bottom surface contact disposes these lines of adhesive in offset spaced parallel relationship and out of contact with each other to avoid self-sealing of the stacked form units. Also, the detached units of web 26 may be stacked one on top of the other without self-adhering, and each of the webs may be respectively storage rolled without their respective form units self-adhering together. At the same time, the lines of adhesive of units 15 and 15a are registrable for self-sealing incident to a stacking between them, and are likewise registrable for self-sealing incident to a respective folding thereof along their respective fold lines.

Obviously, many modifications and variations are made possible in the light of the above teachings. For example, any number of booklet sheets may be formed using fewer or more than the number of form units described. It is therefore to be understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described.
