The inner surface material 40 is slightly smaller than the core material 20 and can cover the portions where the extension portions 32a and 32b of the surface material 30 and the extension portions 32c and 32d are bent to the back surface side of the core material 20. A rectangular polypropylene sheet having a size.

表紙１６の背表紙部１４の内側（内面材４０の表面）には、図２及び図７において示すように、両面粘着テープ５２又は接着剤で、ポリプロピレン製シートからなるシート体５０が接着されている。接着剤は、ホットメルト型接着剤のような加熱して接着するものではなく、加熱しないで接着するものがよい。
このシート体５０は、表紙１６の背表紙部１４の大きさに対応した長方形で、厚さ０．８ないし１．0ｍｍのポリプロピレン製シートで、熱を加えても湾曲しにくく、且つ、被綴じシート１８と熱溶着することができるものである。 As shown in FIGS. 2 and 7, a sheet body 50 made of a polypropylene sheet is bonded to the inner side of the back cover portion 14 of the cover 16 (the surface of the inner surface material 40) with a double-sided adhesive tape 52 or an adhesive. Yes. Adhesives are not heated and bonded like hot melt adhesives, but are preferably bonded without heating.
This sheet body 50 is a rectangular sheet corresponding to the size of the spine cover portion 14 of the cover 16 and is a polypropylene sheet having a thickness of 0.8 to 1.0 mm, is not easily bent even when heat is applied, and is bound. The sheet 18 can be heat-welded.

被綴じシート１８は、多数枚重ね合わせられ、その重ね合わされた端面、すなわち被綴じシート１８のポケットが形成されていない綴じ代である被綴じシート１８が固着される領域において、表紙１６に固着されている。
表紙１６の被綴じシート１８が固着される領域である背表紙部１４の内側のシート体５０の内側面は、溶融され、被綴じシート１８の固着領域たる綴じ代も溶融され、溶融したシート体５０の内面側と被綴じシート１８の綴じ代とを接触させて両者を接合し、被綴じシート１８は表紙１６に固着されている。 A large number of the sheets to be bound 18 are overlapped, and are fixed to the cover 16 in the overlapped end face, that is, in the region where the binding sheets 18 that are binding margins where the pockets of the sheets to be bound 18 are not formed are fixed. ing.
The inner surface of the sheet body 50 on the inner side of the spine cover portion 14, which is an area to which the bound sheet 18 of the cover 16 is fixed, is melted, and the binding margin that is the fixing area of the bound sheet 18 is also melted. The inner surface side of 50 and the binding margin of the binding sheet 18 are brought into contact with each other to join them, and the binding sheet 18 is fixed to the cover 16.

この実施の形態においては、シート体５０は比較的厚みを有し、被綴じシート１８の端縁近傍とシート体５０とを、一定温度に加熱された熱板などからなる発熱体をもって加熱し、被綴じシート１８の固着される領域とシート体５０の固着される領域とを溶融させても、シート体５０は全体が溶融することがなく、その被綴じシート１８に固着される領域の厚み方向の中間まで溶融されるに過ぎない。したがって、発熱体の熱が背表紙部１４まで及ぶことは無い。
また、表紙１６の芯材２０は、ボール紙のような加熱されても比較的カールしにくい材料をもって形成されているので、発熱体による熱が表紙１６の背表紙部１４に及んだとしても、表紙１６はカールすることはない。 In this embodiment, the sheet body 50 has a relatively thick thickness, and heats the vicinity of the edge of the binding sheet 18 and the sheet body 50 with a heating element such as a hot plate heated to a constant temperature, Even if the region to which the binding sheet 18 is fixed and the region to which the sheet body 50 is fixed are melted, the entire sheet body 50 is not melted, and the thickness direction of the region to which the binding sheet 18 is fixed is melted. It is only melted to the middle. Therefore, the heat of the heating element does not reach the back cover portion 14.
Further, since the core member 20 of the cover 16 is formed of a material that is relatively difficult to curl even when heated, such as cardboard, even if heat from the heating element reaches the spine portion 14 of the cover 16. The cover 16 does not curl.

そして、芯材２０の上端縁２２ａおよび下端縁２２ｂよりも外方に延びた表面材３０の延長部３２ａおよび延長部３２ｂ（くるみ領域３６）を芯材２０の上端縁２２ａおよび下端縁２２ｂ近傍において芯材２０の他方主面たる裏面（内側表面）側に折り曲げ、芯材２０の裏面（内側表面）に重ねて接着するとともに、芯材２０の左端縁２２ｃおよび芯材２０の右端縁２２ｄよりも外方に延びた表面材３０の延長部３２ｃおよび延長部３２ｄ（くるみ領域３６）を芯材２０の左端縁２２ｃおよび右端縁２２ｄ近傍において芯材２０の裏面（内側表面）側に折り曲げ、芯材２０の裏面（内側表面）に重ねて接着して芯材２０をくるみ、表紙部材を形成する（図３及び図４図示）。 And the extension part 32a and extension part 32b (case region 36) of the surface material 30 extended outward from the upper end edge 22a and the lower end edge 22b of the core member 20 are located in the vicinity of the upper end edge 22a and the lower end edge 22b of the core member 20. Bend to the back surface (inner surface) side, which is the other main surface of the core material 20, and overlap and adhere to the back surface (inner surface) of the core material 20, and more than the left end edge 22c of the core material 20 and the right end edge 22d of the core material 20. The extended portion 32c and extended portion 32d (case region 36) of the surface material 30 extending outward are bent toward the back surface (inner surface) side of the core material 20 in the vicinity of the left end edge 22c and the right end edge 22d of the core material 20, The core material 20 is wrapped and adhered to the back surface (inner surface) of the cover 20 to form a cover member (shown in FIGS. 3 and 4).

次に、図５に示すような内面材４０を準備する。内面材４０は、芯材２０よりも若干小さく且つ表面材３０の延長部３２ａおよび延長部３２ｂならびに延長部３２ｃおよび延長部３２ｄが芯材２０の裏面側に折り曲げられた部分を覆うことが可能な大きさを有する、芯材２０と相似形である方形のポリプロピレン製シートである。
内面材４０は、表面材３０の延長部３２ａ及び延長部３２ｂ並びに延長部３２ｃ及び延長部３２ｄが芯材２０の裏面側に折り曲げられたくるみ領域３６を覆うように、その裏面接着領域４４を芯材２０の裏面に接着し且つ表面材３０のくるみ領域３６の表面（内側表面側）に、例えば水溶性接着剤によって接着する。 Next, an inner surface material 40 as shown in FIG. 5 is prepared. The inner surface material 40 is slightly smaller than the core material 20 and can cover the portions where the extension portions 32a and 32b of the surface material 30 and the extension portions 32c and 32d are bent to the back surface side of the core material 20. This is a rectangular polypropylene sheet having a size similar to that of the core material 20.
The inner surface material 40 has the back surface adhesion region 44 in the core so that the extension portion 32a and the extension portion 32b of the surface material 30 and the extension portion 32c and the extension portion 32d cover the case region 36 bent to the back surface side of the core material 20. It adheres to the back surface of the material 20 and adheres to the surface (inner surface side) of the case region 36 of the surface material 30 with, for example, a water-soluble adhesive.

次に、背表紙部１４と表表紙部１２ａとの境界線上（表紙１６の上端縁１６ａと表紙１６の下端縁１６ｂと交差する仮想線Ｘ−Ｘ線上）と、背表紙部１４と裏表紙部１２ｂとの境界線上（表紙１６の上端縁１６ａと表紙１６の下端縁１６ｂと交差する仮想線Ｙ−Ｙ線上）において、芯材２０の折り曲げを容易にするために、表面（外側表面）から裏面（内側表面）に向けて表紙１６を凹ませるヒンジ加工を施す（図６図示）。
ヒンジ加工は、芯材２０の折り曲げ部２８ａ（芯材２０の上端縁２２ａと芯材２０の下端縁２２ｂと交差する仮想線Ｘ−Ｘ線上）及び折り曲げ部２８ｂ（芯材２０の上端縁２２ａと芯材２０の下端縁２２ｂと交差する仮想線Ｙ−Ｙ線上）において施されている。 Next, on the boundary line between the spine part 14 and the front cover part 12a (on the imaginary line XX line intersecting the upper edge 16a of the cover 16 and the lower edge 16b of the cover 16), the spine part 14 and the back cover part 12b (on the imaginary line YY line intersecting the upper edge 16a of the cover 16 and the lower edge 16b of the cover 16) on the boundary line with the surface 12b, in order to facilitate the bending of the core member 20, from the front surface (outer surface) to the back surface Hinge processing is performed to dent the cover 16 toward the inner surface (shown in FIG. 6).
Hinge processing is performed on the bent portion 28a of the core member 20 (on the imaginary line XX line intersecting the upper end edge 22a of the core member 20 and the lower end edge 22b of the core member 20) and the bent portion 28b (upper edge 22a of the core member 20). (On the imaginary line YY line intersecting the lower end edge 22b of the core material 20).

次に、図７において示すように、背表紙部１４の内側面（内面材４０の表面）に、両面粘着テープ５２によって、厚さ０．８ないし１．０ｍｍの長方形のポリプロピレン製シート体５０を貼り付ける。 Next, as shown in FIG. 7, a rectangular polypropylene sheet 50 having a thickness of 0.8 to 1.0 mm is applied to the inner side surface (the surface of the inner surface material 40) of the spine cover portion 14 by a double-sided adhesive tape 52. paste.

一方、被綴じシート１８を多数枚重ね合わせた被綴じシート群を準備し、その固着される領域である端縁の近傍すなわち綴じ代を、背表紙部１４の内側に対向させる。
このとき、表紙１６は、表表紙部１２ａと裏表紙部１２ｂとを折り曲げ部２８ａ及び折り曲げ部２８ｂで折り曲げ、表表紙部１２ａと裏表紙部１２ｂとは対向した状態にする。 On the other hand, a group of sheets to be bound in which a large number of sheets to be bound 18 are overlapped is prepared, and the vicinity of the edge, that is, the binding area, that is, the binding margin, is opposed to the inside of the spine portion 14.
At this time, the front cover 16 bends the front cover portion 12a and the back cover portion 12b with the bent portions 28a and 28b so that the front cover portion 12a and the back cover portion 12b face each other.

そして、図８において示すように、対向した背表紙部１４の内側のシート体５０の内側面と被綴じシート１８の綴じ代との間に、内部にシーズヒーター等が内蔵された板状の発熱体６０を介在させ、ポリプロピレン製シート体５０の溶融温度が１２０℃ないし１３０℃に対し、発熱体６０を１７０℃ないし１８０℃前後に加熱し（図９参照）、背表紙部１４のシート体５０と被綴じシート１８の綴じ代に接触させて両者を溶融させる（図１０参照）。その後、発熱体６０を引き抜き（図１１参照）、被綴じシート１８とシート体５０とを接触させて（図１２参照）、シート体５０の内側面に被綴じシート１８の綴じ代を溶着し、表紙１６に被綴じシート１８からなる被綴じシート群を固着する（図１３参照）。 Then, as shown in FIG. 8, a plate-like heat generation in which a sheathed heater or the like is built in between the inner side surface of the sheet body 50 inside the facing spine portion 14 and the binding margin of the binding sheet 18. With the body 60 interposed, the heating element 60 is heated to around 170 ° C. to 180 ° C. with respect to the melting temperature of the polypropylene sheet 50 between 120 ° C. and 130 ° C. (see FIG. 9). And the binding margin of the binding sheet 18 is brought into contact with each other to melt them (see FIG. 10). Thereafter, the heating element 60 is pulled out (see FIG. 11), the bound sheet 18 and the sheet body 50 are brought into contact (see FIG. 12), and the binding margin of the bound sheet 18 is welded to the inner surface of the sheet body 50. A bound sheet group including the bound sheets 18 is fixed to the cover sheet 16 (see FIG. 13).

この実施の形態によれば、発熱体６０の熱は、シート体５０にのみ及び、シート体５０の内側面近傍と被綴じシート１８の綴じ代を溶融させるのみで、シート体５０の外側面、すなわち背表紙部１４に接着された面側を溶融させること無く、且つ、表紙１６の背表紙部１４には余り及ばない。仮に熱が及んだとしても、芯材２０は、カールしにくいものからなるために、表紙１６と背表紙部１４は湾曲することなく適宜な形状を保持している。 According to this embodiment, the heat of the heating element 60 is applied only to the sheet body 50, and only by melting the vicinity of the inner surface of the sheet body 50 and the binding margin of the binding sheet 18, That is, the surface side bonded to the spine portion 14 is not melted and does not reach the spine portion 14 of the cover 16 so much. Even if heat is applied, since the core member 20 is made of a material that is difficult to curl, the cover 16 and the spine portion 14 are kept in an appropriate shape without being curved.
