Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a book decoration headband and a method of manufacturing the same.
[0002]
[Prior art]
In general, as shown in FIG. 8 (a), the headband H is composed of a single meandering weft a whose adjacent portions are parallel to each other and a plurality of warps b woven to intersect the parallel portion of the weft a. For example, by a narrow woven fabric woven in a belt shape by a needle type loom. Then, as shown in FIG. 9, after the headband H wound around the reel c and pulled out from the reel c is cut into a predetermined dimension by the cutting blade d, as shown in FIG. It is interposed between the upper and lower ends and the back cover f and is used for reinforcement and decoration of the binding portion of the book e. For this reason, beautiful colors and strengths that are common to textiles are required, but the length is cut into several centimeters for adhesion due to the particularity of the application, so high adhesion is also required. Therefore, in the headband of another manufacturing method called the flower cloth headband, in order to improve the adhesion, a material in which a thin paper is laminated on a fabric is used as a material and processed so that the thin paper appears on the adhesive surface. Yes.
[0003]
[Problems to be solved by the invention]
However, in a book binding headband formed by weaving a single meandering weft whose adjacent portions are parallel to each other and a plurality of warp yarns woven crossing the parallel portions of the weft, a thin paper is used. Although a method of laminating so as to appear on the adhesive surface is also conceivable, there is a problem that this method requires a lot of man-hours and labor and increases costs.
[0004]
In addition, if the cutting is forcibly performed, the cutting edge is narrowed as shown in FIG. 8 (b), and there is a possibility that a defective product may be continuously produced. This reduces the yield and the product quality in the continuous bookbinding process. There was a problem of causing a drop.
[0005]
By the way, in the bookbinding process, in recent years, automatic bookbinding machines having a capacity of several hundred to several thousand books per hour have become widespread. Become intense. Therefore, as shown in FIG. 8 (b), the cut of the headband H is incomplete, the width of the warp b of the cut end of the headband H followed by the weft a that has not been cut is reduced, There was a problem of causing a shift in the bonding position.
[0006]
The present invention has been made in view of the above circumstances, and provides a headband for book decoration and a manufacturing method capable of improving adhesion to a book and improving cutting performance by a simple manufacturing method. Objective.
[0007]
[Means for Solving the Problems]

[0012]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below in detail with reference to the drawings.
[0013]
FIG. 1 is a schematic configuration diagram showing an example of a book-dressing headband H according to the present invention, and FIG. 2 is a schematic configuration diagram showing a cutting portion C of the headband H.
[0014]
The headband H is formed to have an appropriate width, for example, 12 mm, and a single meandering weft 1 whose adjacent portions are parallel to each other, and a plurality of, for example, 10 woven to intersect the parallel portions of the weft 1. The warp yarns 2, 2... (For example, 6 are shown in the drawing) and the warp yarns 2 a for converging 8 to 10 yarns are woven in a band shape, and adjacent weft yarns 1 a and 1 b on both sides are woven. Connected in a loop. In this case, on one side of the headband H, adjacent wefts 1a, 1b form a large number of loop portions 3, and these loop portions 3 are inserted into the adjacent loop portions 3 with a certain directionality, The loop portion 3 is bent in a chain shape (this way of bending is hereinafter referred to as chain stitch). On the other hand, the ear part 4 having an appropriate width, for example, a bulge of about 3 mm, is formed on the other side part by weaving the warp yarns 2a for concentrating 8 to 10 pieces as described above. In addition, in the vicinity of the warp 2 of the loop portion 3 to which the chain stitch is applied, the lock yarn 5 having the winding portion 5a extends in the warp 2 direction, and each of the wefts 1a and 1b forming the loop portion 3 is It winds so that the said winding part 5a may clamp | tighten. As described above, the lock yarn 5 is wound so as to fasten each of the wefts 1a and 1b forming the loop portion 3, so that the position of the wefts 1a and 1b when the headband H is woven is maintained. On the other hand, the ear part 4 having an appropriate width, for example, a bulge of about 3 mm, is formed on the other side part by weaving the warp yarn 2a for the ear part made of the colored yarns of 8 to 10 as described above. Has been. The weft 1 is made of, for example, rayon fiber, and the warp 2 is made of, for example, suf fiber.
[0015]
The adhesion promoter 6 for improving the adhesiveness of the surface of the headband H and for improving the cutting property is applied to at least one surface of the ground portion where the ear portion 4 of the headband H is left. . In this case, the region to be applied is preferably a portion excluding the ear portion 4 of the headband H. As the adhesion promoter 6, a paste, for example, a dextrin aqueous solution mixed with pulp or hydrophilic short fibers (length is preferably 1 mm or less) in an appropriate amount is used.
[0016]
By applying such an adhesion promoter 6 to the surface of the headband H, the short fibers or fibrils or microfibrils (hereinafter referred to as short fibers) in the pulp are uniformly entangled with the surface of the headband H. Since the positional relationship between the weft 1 and the warp 2 in the headband H is maintained, and the weft 1 and the warp 2 are difficult to shift when the headband H is cut, the cutting performance is improved. In addition, the adhesive action of the adhesion promoter 6 can prevent the cut end from being cut. Moreover, since the above-mentioned hydrophilic short fibers or the like cause moderate fuzz and irregularities on the surface of the headband H, the adhesiveness by the adhesive is improved. Therefore, as shown in FIGS. 2 and 9, since the headband H cut to an appropriate length, for example, several centimeters, can be strongly bonded to the binding portion of the book, the reinforcing effect when the book is loaded is increased.
[0017]
Next, a method for improving the adhesiveness of the one-side surface of the headband H and improving the cutting performance of the headband H will be described with reference to FIGS.
[0018]
FIG. 3 is a schematic configuration diagram showing a process of applying the adhesion promoter 6 for improving the adhesiveness and cutting property of the surface of the headband H, and FIG. 4 is a schematic diagram showing the main part of FIG. It is a top view.
[0019]
The apparatus for applying the adhesion promoter 6 to the headband H is for drying while applying tension to the glued headband H for applying tension to the headband H sent after weaving and the glued headband H. The drying processing unit 15 and the adhesion promoting processing unit 19 for improving the adhesiveness and cutting property of the headband H according to the present invention are mainly configured.
[0020]
The gluing processing unit 12 has a lower end portion in which a dextrin tank 9 in which a paste, for example, a dextrin aqueous solution 8 is stored, and a headband H that is wider than at least the headband H and is fed through the guide roller 7 is in contact. In order to remove the excess dextrin aqueous solution 8 attached to the headband H after being immersed in the dextrin solution 9 and the holding member 10 arranged to be immersed in the dextrin aqueous solution 8 A pair of squeezing rollers 11a and 11b are provided. A roller 10 a that is wider than at least the headband H and is rotatable is disposed at the lower end of the holding member 10, that is, the portion that contacts the headband H.
[0021]
In addition, the drying processing unit 15 has a pair of guide frames 13a and 13b having a width wider than at least the headband H and arranged substantially parallel to each other and at substantially the same height with an appropriate interval therebetween, and below In addition, a plurality of rotating drums 14a to 14e (described in the case of five in the figure) are arranged in parallel with each other at an appropriate interval. In this case, the rotating drums 14a to 14e are formed so as to be rotatable around an axis (not shown) in an appropriate direction by driving from a driving means (not shown). The width of the rotating drums 14a to 14e, that is, the length in the axial direction is considerably larger than the width of the headband H. For example, the headbands H are arranged at an appropriate interval so as not to be substantially parallel to each other. , A width of about 10 to 20 is preferable.
[0022]
On the other hand, the adhesion promotion processing unit 19 is disposed so that the adhesion promoter tank 16 storing the solution of the adhesion promoter 6 and the lower end portion are immersed in the solution of the adhesion promoter 6 in the adhesion promoter tank 16. The application roller 17 is rotatable, and the guide roller 18 has a driving means (not shown) and is arranged so as to circumscribe the application roller 17. The width of the guide roller 18 is at least larger than that of the headband H, and the application roller 17 has a width corresponding to the area where the adhesion promoter 6 is applied, for example, the ear 4 in the headband H. The width is the extent of removal (see FIGS. 5A and 5B). In this case, the adhesion promoter 6 only has to be applied to the portion of the headband H where the ears 4 are left as a result. Therefore, even if the width of the application roller 17 is increased, the adhesion promoter 6 is applied by the scraper 17a. Just scrape.
[0023]
The means for applying the adhesion promoter 6 in the adhesion promotion processing section 19 is not limited to the application roller 17, and can apply the adhesion promoter 6 to an appropriate width on at least one surface of the headband H. If necessary, the configuration may be arbitrary. For example, the coating spray 30 may be used to spray the solution of the adhesion promoter 6 on the headband H in the vicinity of the guide roller 18a having a driving means (not shown) (see FIG. 6). . Alternatively, the frustoconical immersion roller 40 having the rotation shaft 40a inclined at an appropriate angle with respect to the vertical direction and having at least the same width as the headband H may be rotatably provided by a driving means (not shown). . In this case, the immersion roller 40 guides the headband H so that the ear portion 4 side faces upward, and the solution of the adhesion promoter 6 stored in the adhesion promoter tank 16a has a lower side of the headband H. The adhesion promoter 6 is disposed so as to be immersed by a width to be applied, that is, a width excluding the ear portion 4 (see FIG. 7).
[0024]
In addition, a receiving container 21 that houses the headband H that has been subjected to all the processes, and a rotatable pulley 20 having a driving means for guiding the headband H to the receiving container 21 are provided near the drying processing unit 15. And on the opposite side of the gluing section. Of the means for feeding the headband H, the rotational speed of the means having a driving means, for example, the guide roller 18, the rotating drums 14a to 14e, the squeezing rollers 11a and 11b, the pulley 20, etc. The feed speed is adjusted to be the same. By making such adjustments, the dextrin aqueous solution 8 and the adhesion promoter 6 can be dried while giving an appropriate tension without being bent in the process of feeding the headband H. Therefore, a headband H with a beautiful finish and high workability such as cutting can be obtained.
[0025]
Next, the operation | movement aspect of the apparatus which performs the application | coating process of the adhesion promoter 6 shown in FIG.3 and FIG.4 is demonstrated.
[0026]
One headband H woven from the weft 1 and the warp 2 is woven, and then sent to the apparatus for performing the adhesion promoting process, and is first sent to the gluing processing section 12 via the guide roller 7. The sent headband H is immersed in the dextrin aqueous solution 8 stored in the dextrin tank 9 so as to be restrained by the roller 10a provided at the lower end of the restraining member 10, and is glued. After that, the glued headband H that has come out of the dextrin tank 9 is sent to a pair of squeezing rollers 11a and 11b arranged so as to be parallel and close to each other, and is sandwiched between the squeezing rollers 11a and 11b. Thus, excess dextrin aqueous solution 8 is removed in the process of passing.
[0027]
The headband H sent out from the gluing processing unit 12 is sent to the drying processing unit 15 for drying the adhered glue. In the drying processing unit 15, first, the headband H passes through the guide frames 13 a and 13 b in this order, and is sent to the upper side opposite to the gluing processing unit 12 of the drying processing unit 15. Of the rotating drums 14a to 14e disposed below 13b, the rotating drums 14a to 14e are fed so as to come into contact with the lower side of the rotating drum 14a disposed at the same side end as the feeding direction from the guide frames 13a to 13b. The headband H that has passed through the lower part of the rotating drum 14a is guided to contact the upper part of the rotating drum 14b that is adjacent obliquely above the rotating drum 14a, and is then guided to the rotating drum 14c that is adjacent obliquely below, Similarly, the rotary drums 14d and 14e are guided so as to come into contact with each other.
[0028]
In this way, the headband H passes through the rotating drums 14a to 14e so as to form a meandering shape, and the headband H that has passed through the rotating drum 14e is sent to the guide frame 13a again. In the same manner, the same process is repeated after the guide frame 13b is sequentially sent to the rotating drums 14a to 14e, and further returned to the guide frame 13a. In this way, a series of steps of making a round from the guide frame 13a and returning to the guide frame 13a is repeated a plurality of times, for example, about 10 to 20 times. In this case, when the headband H returns to the guide frame 13a, The headband H gradually shifts its position while making a round of the drying processing section 15 so as not to overlap with the headband H of the headband H, and is sent so as to be substantially parallel to each other. (See FIG. 4 (a)). Such a process is repeated an appropriate number of times, and the headband H that has passed through the rotary drum 14e in the last round is sent to the guide roller 18. By performing such treatment, the dextrin aqueous solution 8 can be dried while applying tension to the headband H, so that the headband has a beautiful finish and has high workability such as cutting without being twisted or wrinkled. H can be obtained.
[0029]
After the drying process is completed, the adhesion promoter 6 is applied by the adhesion promotion processing unit 19 in the process in which the headband H is sent from the rotary drum 14e to the guide roller 18. In this case, the application roller 17 provided so as to circumscribe the lower side of the guide roller 18 rotated by the driving means and so that the lower end portion is immersed in the adhesion promoter 6 stored in the adhesion promoter tank 16 is provided. Rotate according to the guide roller 18. Thereby, when contacting the headband H guided by the guide roller 18, the adhesion promoter 6 that adheres to the edge of the application roller 17 at any time is applied to the region where the ear portion 4 does not exist.
[0030]
The headband H that has been subjected to adhesion promotion processing is again sent to the guide frame 13a, and then guided to the pulley 20 that rotates by the driving means. The headband H that has passed so as to contact the pulley 20 is accommodated in a receiving container 21 provided in the lower portion of the pulley 20, and a series of steps of the adhesion promoting process is completed.
[0031]
In the above-described embodiment, the case where the adhesion promotion processing unit 19 is provided at a position where the adhesion promotion process is performed immediately after the drying process has been described. An adhesion promotion processing unit 19 may be provided at a position where the adhesion promotion processing can be performed immediately after that, that is, between the squeezing rollers 11a and 11b and the guide frame 13a.
[0032]
In the above embodiment, a chain stitch is applied to the loop portion 3 formed of the weft 1 on one side of the headband H, and a plurality of, for example, 8 to 10 ear warps 2a are provided on the other side. Although the case where the converged ear part 4 is formed has been described, it is needless to say that it can be applied to other headbands.
[0033]
In the above embodiment, the headband for book decoration has been described. However, if the woven fabric is required to have a high cutting property and / or adhesiveness, the same effect as that of the above embodiment can be obtained by applying the present invention. It is done.
