Description

  The present invention relates to a bookbinding facing sheet provided with a cured hot melt adhesive layer.

Bookbinding wrapped in a hard cover is well known. In such bookbinding, core papers such as paperboards that form the front palm, the back, and the back palm of the book on the back cover side of the book are juxtaposed, and the core papers are juxtaposed. Cover the top surface of the cover paper, fold it back to the appropriate width back along the edge of the core paper, and stick it to each core paper to create a hard cover. There is a so-called simple upper bookbinding that combines the main body (hereinafter referred to as the main body) created by binding the back with glue and sticking the facing paper on the back side and back side of the back, thereby completing the bookbinding. is there.

  However, when pasting the facing paper on the back of the palm, generally starch glue or water-soluble synthetic resin glue is used as an adhesive, and this glue is applied to the facing paper using a roller or a brush. Before being bent and before the adhesive strength becomes too strong, it is necessary to apply it quickly, and skill is required for the attaching operation. In addition, since it is a liquid adhesive, it takes time and effort to prepare and clean up, and it is good when a large amount of books are bound, but when the amount is small, the ratio of the setup time becomes large and the productivity is remarkably lowered. Furthermore, it may take a long time to correct the warpage of the cover due to the penetration of moisture into the cover.

  In order to reduce the time and effort of such affixing work, it is considered to use facing paper with a sheet adhesive or double-sided adhesive tape attached. If present, the facing paper can be pasted on the back of the palm by a simple operation of pressing the back of the palm on the adhesive. However, since the adhesive does not completely solidify over time, there is a problem that the facing paper may peel off from the cover in some cases.

  The problem to be solved by the present invention is that it can be easily performed without requiring skill in attaching the facing paper to the cover, reducing the labor and time required for the pasting work, and maintaining a strong adhesive force after pasting. To provide paper.

  The present invention is a facing paper that is bound to the back of the cover with the back of the text, and is cured on the entire surface of the facing paper on the side of the cover that is attached to the back of the cover. The main feature is that an adhesive layer is formed on the center surface excluding the peripheral surface.

  In the present invention, the cover is closed and the back side of the cover is turned over and pressed over the hot melt adhesive layer and the adhesive layer of the paper, and the cover and the paper are temporarily bonded with the adhesive, and the cover is attached in this state. The upper surface of the facing paper is heated and pressed to dissolve the hot melt adhesive, and the cover and the facing paper are finally bonded. Temporary adhesion with adhesive allows the facing paper to be pasted even if the cover is opened. Even if the cover is closed after bonding with hot-melt adhesive, bending of the facing paper near the groove of the book occurs. do not do.

  Therefore, according to the facing paper according to the present invention, it is possible to perform a simple operation of the temporary bonding with the cover closed and the main bonding with the cover open, and to accurately bond the cover and the facing paper in a short time. This is due to the melt adhesive, and the adhesive strength is strong, and there is no possibility that the facing paper will be peeled off from the cover. Thus, it is possible to easily apply the facing paper without requiring skill, and it is possible to efficiently create the upper bookbinding and the simple upper bookbinding even with a small number of copies.

  The purpose of providing facing paper is that it can be easily applied to the cover of facing paper without the need for skill, reduces the labor and time required for pasting work, and maintains strong adhesive strength after pasting. This was achieved by forming a combination of a hot melt adhesive and a pressure sensitive adhesive.

  1 is a perspective view showing the structure of the main body according to the embodiment, FIGS. 2 to 4 are process drawings showing the assembly of the main body and the cover, and FIG. In FIG. 1, H is the body, 1 is the text, 2 is the facing paper, and 3 is the cold coffee. The facing paper 2 is formed by folding one sheet into two, one of which is a paper 2a and the other is a paper 2b. A hardened hot melt adhesive layer 4 is formed on the entire outer surface of the paper 2a. A rectangular pressure-sensitive adhesive layer 5 is formed in the central portion excluding the peripheral edge surface of 2a and the portion where the cold water bottle 3 contacts.

  Then, the back of the main body 1 and the folding position of the facing paper 2 are arranged with the back, and a hot melt adhesive is applied to the back and bound with a cold chill 3 to form an appropriate throat groove, thereby completing the body H. . The completed body H is matched with a hard cover 6 prepared in advance as shown in FIG. The front cover 6 is formed by juxtaposing core papers 6a, 6b, and 6c such as paperboards that form the front cover, the back, and the back cover of the book on the back cover side of the book. A cover sheet 7 is placed on the cover sheet 7 and folded back 7a to the appropriate width back side along the edges of the core sheets 6a, 6b, 6c and attached to the respective core sheets to create a hard cover sheet.

  When there is a release paper on the upper surface of the hot melt adhesive layer 4 and the pressure-sensitive adhesive layer 5 in a state where the cover 6 and the body H are combined, this is peeled off and the cover 6 is closed and pressed. The pressure-sensitive adhesive layer 5 formed on the paper 2a of the facing paper 2 by this pressing causes the paper 2a located on both sides of the main body H to adhere to the back side of the front and back sides, respectively. In this state, the cover 6 is opened as shown in FIG. 3, and the hot melt adhesive layer is dissolved by pressing with a heating rod or the like from the upper surface of the paper 2a. Due to this dissolution, the paper 2a is adhered to the entire back surface of the front and back sides. After that, the cover 6 is closed as shown in FIG. 4 and pressed until the hot melt adhesive is almost cured to complete bookbinding as shown in FIG.

  In the case of facing paper formed by combining hot melt adhesive and adhesive in this way, the cover is opened with the adhesive sticking position of the facing paper fixed with the adhesive, and the melting of the hot melt adhesive is performed from above the facing paper. It is possible to perform the bonding with the hot melt adhesive reliably and easily. That is, a facing sheet in which a hot melt adhesive layer is formed in advance can be used for bonding the facing sheet to the cover. Accordingly, it is possible to easily apply the facing paper without requiring skill, and it is possible to efficiently create the upper bookbinding and the simple upper bookbinding even with a small number of copies.

  In the above embodiment, the rectangular pressure-sensitive adhesive layer is formed in the central portion excluding the peripheral edge surface of the facing paper on which the hot-melt adhesive layer is formed in advance to increase the adhesive strength of the peripheral edge surface. The pressure-sensitive adhesive layer formed on the paper is arbitrary, such as circular or linear, and may be applied to the peripheral edge surface of the facing paper. For example, the facing paper may be formed in a line extending from one end to the other end.

It is a perspective view which shows the structure of the main body based on the Example of this invention. It is process drawing which shows the assembly of the main body and cover shown in FIG. It is process drawing which shows the assembly of the main body and cover shown in FIG. It is process drawing which shows the assembly of the main body and cover shown in FIG. FIG.
