Description
1(~6~3~Z
m e subject invention generally relates to books having protective covers and, in particular, to a book integrally manufactured with a removable protective cover.
It should be noted that a method, disclosed hereinafter, for manufacturing said book is the subject matter of a U.S.
Patent 3,940,904.
In business offices multi-page reports are frequently bound with adhesive strips to provide books for local and dis-tant distribution. To keep the books closed during distribu-tion the books are often placed in envelopes or have a band individually placed around them. While bands facilitate handling of books during a distribution process they are not useful when books contain sensitive subject matter because bands may be slipped into association and disassociation with a book without detection. Similarly, when envelopes are used for distributing or mailing books, books may be removed from the envelopes, ma~- be read, and may be reinserted in suitably addressed and similar envelopes.
It is an object of the present invention to provide mailable ~ooks having integrally associated protective covers.
It is another object of the present invention to provide a book having a security cover, any opening or removal of the cover being readily detectable.
Briefly, the invention herein provides a covered book. Structurally, the book comprises: (a) a stack of aligned sheets providing an edge surface; (b) a first pro-tective sheet located adjacent the first sheet of the stack;
(c) a second protective sheet located adjacent the last sheet of the stack and said first protective sheet; (d) an adhesive binding strip fixed to the sheets along said edge surface and :1061 331Z
to the outside of the protective sheets; and (e) means for flxing the first protective sheet to the second protective sheet.
Additional objects and features of the invention will become apparent by reference to the following descrip-tion in conjunction with the accompanying drawinys, in which:
Fig. 1 is a perspective view of a book, according to the invention;
Fig. 2 is a plan view of an end of the book shown in Fig. l; and Fig. 3 is a plan view of an end of the adhesive bearing strip, used in making the book, shown in Figs. 1 and

to the outside of the protective sheets; and (e) means for flxing the first protective sheet to the second protective sheet.
Additional objects and features of the invention will become apparent by reference to the following descrip-tion in conjunction with the accompanying drawinys, in which:
Fig. 1 is a perspective view of a book, according to the invention;
Fig. 2 is a plan view of an end of the book shown in Fig. l; and Fig. 3 is a plan view of an end of the adhesive bearing strip, used in making the book, shown in Figs. 1 and
2, a section of the strip having been removed to more fully disclose components of the strip.
Referring to Figs. 1 and 2, a ~ook 10, according to the invention, includes a rectangular stack of aligned sheets 11, 17,and 18 providing an edge surface 16. Adjacent the first sheet 18 of the stack there is located a rectangular protective sheet 12. Sheet 12, for example, may be manufac-tured from kraft paper with length and width dimensions suit-able for covering a longitudinal section of sheet 18. Adja-cent the last sheet 17 of the stack there is located another protective sheet 14 which, for example, may be manufactured from kraft paper. Rectangular sheet 14 has a width dimension large enough to cover the length of the book and long enough to extend around edge 30 of the stack into overlapping rela-tionship with sheet 12. The stack of aligned sheets 11, 17 and 18 and the protective sheets 12 and 14 are mutually coupled by an adhesive bearing strip 19.
As disclosed in Fig. 3, adhesive strip 19 comprises 1~68312 a formable substrate 20 of, typically, relatively heavy paper stock, and adhesive coatings 21 and 22. Adhesive coatings 21 and 22 constitute a plurality of strip-like formations com-prising two heat activated adhesive types. Heat activated adhesive may be either of the low or high tack types. A
low tack adhesive comprises an adhesive material which when heated becomes fairly molten or fluid, thereby providing a high degree of surface wet-out with a minimum application o~
pressure or heat. A typical low tack adhesive may be a mixture of about 80% by weight of an ethylene/vinyl acetate copolymer having a 90% ratio of ethylene to vinyl acetate and about 20% by weight of rosin acid ester. A high tack adhesive comprises an adhesive material which when heated remains highly viscous and somewhat immobile so that a definite amount of heat is necessary to wet-out a surface being adhered. A
typical high tack a & esive may be a mixture of polyethylene, a rosin acid, and a metal ~alt of a carboxylic acid, present in weight proportions of 80/10/10, respectively. High tack adhesives have the advantage that, on application of heat and pressure, the bond created thereby immediately possesses a high degree of strength.- on the other hand, the low tack adhesive ~lows readily or is wicked into the edges of paper sheets to be bound. The strip 19 preferably has the high tack adhesive 21 uniformly applied to the substrate 20 while the low tack adhesive 22 is applied along the center line of the substrate with a relatively greater thickness than that of the high tack material. Typically, the width of the adhe-sive 22 is approximately equal to or slightly greater than the overall thickness of the stack of sheets 11.
Referring to Figs. 1 and 2, protective sheet 14 extends snugly around the unbound edge 30 of the stack of iL~6~33~Z
sheets and is fixed, near its end 24, by an adhesive 25 to protective sheet 12. Adhesive 25 may be of the pressure sen-sitive type and, preferably, should have a holding strength sufficient to prevent separation of protective sheets 12 and 14 unless detectable tearing of either of the sheets 12 and 14 occurs.
Sheet 12 is scored with a linear series of slits 28 spaced from and parallel to edge 13 of the sheet and binding strip 19 is fixed to an area between slit 28 and edge 13.
Similarly, sheet 14 is scored with a linear series of slits spaced from its end 15 and adhesive strip 19 is fixed to an area of sheet 14 which is located between slit 27 and end 15.
Thus, substantial sections of the protective sheets 12 and 14 may be separated from the book along the series of slits 28 and 27, respectively, when they are no longer required.
Ends 13 and 15 of protective sheets 12 and 14, respectively, may be lo~ated so as to coincide with edge surface 12; however, it is preferred that they be spaced away from the edge surface to provide areas on sheets 17 and 18 engageable by strip 19. The stated preference exists because when said substantial parts of the protective sheets 12 and 14 are removed sheets 17 and 18 will remain as covers and in normal use shear s~résses between adhesive strip 19 and shee~s 17 and 18 are expected. Since sheets 17 and 18 will serve as covérs when the protective sheet~ are at least partially re-moved they should be manufactured from stock which is thicker and more durable than the sheets which make up the pages of book 10.
The book 10, described above, may be manufactured by aligning the stack of sheets 11, 17 and 18 to provide edge surface 16. The alignment may be accomplished, for example, by jogging the sheets against a flat sur~ace. During or after the alignment step sheets 12 and 14 may be located, as described above, adjacent sheets 1~ and 17, respectively. Thereafter, ad-hesive strip l9 is fixed to the edge surface 16, the protective sheets 12 and 14, and when the preference stated above is de-sired, to sheets 17 and 18. The alignment of the stack of sheets and the location of the protective sheets are steps which may be adequately performed manually. However, fixing of the adhesive strip l9 to the resulting structure is best accom-plished with a bookbinding machine such as is disclosed in pending U.S. Patent 3,928,118 by R. Kuhns. Subsequently, protective sheet 14 may be fixed to protective sheet 12 with, for example, a suitable adhesive.
It is noted that binding strîps and applicators other than those described above may be used to provide covered books according to the invention. In view of this and the fact that other modifications which do not deviate from the spirit of the invention will be readily apparent to those skilled in the art, it is to be understood that the descrip-tion set forth above of a preferred embodiment of the invention has been set forth as an example thereof and is not to be con-strued or interpreted as a limitation on the claims which follow and define the invention.
Referring to Figs. 1 and 2, a ~ook 10, according to the invention, includes a rectangular stack of aligned sheets 11, 17,and 18 providing an edge surface 16.

The stack of aligned sheets 11, 17 and 18 and the protective sheets 12 and 14 are mutually coupled by an adhesive bearing strip 19.
As disclosed in Fig. 3, adhesive strip 19 comprises 1~68312 a formable substrate 20 of, typically, relatively heavy paper stock, and adhesive coatings 21 and 22. Adhesive coatings 21 and 22 constitute a plurality of strip-like formations com-prising two heat activated adhesive types. Heat activated adhesive may be either of the low or high tack types. A

Typically, the width of the adhe-sive 22 is approximately equal to or slightly greater than the overall thickness of the stack of sheets 11.
Referring to Figs. 1 and 2, protective sheet 14 extends snugly around the unbound edge 30 of the stack of iL~6~33~Z
sheets and is fixed, near its end 24, by an adhesive 25 to protective sheet 12. Adhesive 25 may be of the pressure sen-sitive type and, preferably, should have a holding strength sufficient to prevent separation of protective sheets 12 and 14 unless detectable tearing of either of the sheets 12 and 14 occurs.
Sheet 12 is scored with a linear series of slits 28 spaced from and parallel to edge 13 of the sheet and binding strip 19 is fixed to an area between slit 28 and edge 13.
Similarly, sheet 14 is scored with a linear series of slits spaced from its end 15 and adhesive strip 19 is fixed to an area of sheet 14 which is located between slit 27 and end 15.
Thus, substantial sections of the protective sheets 12 and 14 may be separated from the book along the series of slits 28 and 27, respectively, when they are no longer required.
Ends 13 and 15 of protective sheets 12 and 14, respectively, may be lo~ated so as to coincide with edge surface 12; however, it is preferred that they be spaced away from the edge surface to provide areas on sheets 17 and 18 engageable by strip 19. The stated preference exists because when said substantial parts of the protective sheets 12 and 14 are removed sheets 17 and 18 will remain as covers and in normal use shear s~résses between adhesive strip 19 and shee~s 17 and 18 are expected. Since sheets 17 and 18 will serve as covérs when the protective sheet~ are at least partially re-moved they should be manufactured from stock which is thicker and more durable than the sheets which make up the pages of book 10.
The book 10, described above, may be manufactured by aligning the stack of sheets 11, 17 and 18 to provide edge surface 16. The alignment may be accomplished, for example, by jogging the sheets against a flat sur~ace. During or after the alignment step sheets 12 and 14 may be located, as described above, adjacent sheets 1~ and 17, respectively. Thereafter, ad-hesive strip l9 is fixed to the edge surface 16, the protective sheets 12 and 14, and when the preference stated above is de-sired, to sheets 17 and 18. The alignment of the stack of sheets and the location of the protective sheets are steps which may be adequately performed manually. However, fixing of the adhesive strip l9 to the resulting structure is best accom-plished with a bookbinding machine such as is disclosed in pending U.S. Patent 3,928,118 by R. Kuhns. Subsequently, protective sheet 14 may be fixed to protective sheet 12 with, for example, a suitable adhesive.
It is noted that binding strîps and applicators other than those described above may be used to provide covered books according to the invention. In view of this and the fact that other modifications which do not deviate from the spirit of the invention will be readily apparent to those skilled in the art, it is to be understood that the descrip-tion set forth above of a preferred embodiment of the invention has been set forth as an example thereof and is not to be con-strued or interpreted as a limitation on the claims which follow and define the invention.
