クロス等の新規な目開き矯正法及び装置に関する。Detailed Description of the Invention (Field of Industrial Application) The present invention provides a novel method and device for correcting the opening that occurs in a fabric whose density is relatively low relative to the diameter of the yarn used. In particular, the present invention relates to a novel method and device for correcting the opening of textiles used as industrial materials, such as coati cloth, cloth for fiber-reinforced plastics, and the like.

於いては、繊維と樹脂が別個に存在し、ＦＲＰの物性を
落とす結果ともなる。(Prior Art) There are various kinds of textiles used as industrial materials, but among them, many of the textiles used as sheets have a relatively low density and have a mesh structure. When a coating such as rubberization is applied to such textiles, the surface becomes uneven, reducing its commercial value. It may drop. Furthermore, in cloth for fiber-reinforced plastics (hereinafter abbreviated as FRP), fibers and resin exist separately, resulting in deterioration of the physical properties of FRP.
この様なクロスのメソシュ構造（目開き）は時として問
題となる場合があり、従来、この様なクロスの組織から
発生する目開きを矯正する有効な手段はなく、従って一
般的にはクロスを構成する糸の密度を増加せしめること
によって目開きを少なくする手段がとられて来た。This kind of mesh structure (opening) of cloth can sometimes be a problem, and conventionally there is no effective means to correct the opening caused by the structure of cloth. Measures have been taken to reduce the opening by increasing the density of the constituent threads.
しかし、この様な手段により目開きを少なくすることは

にＦＲＩ’に使用される織物を構成する糸は高弾性で脆
く、他の目開き矯正方法であるプレスにより繊維が折損
する現象があり、適切な方法がないのが現状である。However, reducing the opening by such means is not an economically preferable method, and there has been a demand for a method of reducing the opening without changing the density of the fabric. In particular, the threads constituting the fabric used in FRI' are highly elastic and brittle, and there is a phenomenon in which the fibers break when pressed, which is another method for correcting openings, and there is currently no suitable method.
また、プレスによる目開き矯正法は予期する程にはその

、金網等）を通過せしめる方法では、該金属が圧延され
て織物の空間部を閉じ目開きの矯正が行われる。Furthermore, the reality is that the eye opening correction method using a press is not as effective as expected. In the general method of opening correction using a press, that is, a method in which a fabric (e.g., wire mesh, etc.) made of a malleable material such as metal is passed between a pair of pressurized rolls, the metal is rolled. Then, the space in the fabric is closed and the opening is corrected.

なるためである。On the other hand, for fabrics with high elastic modulus used in FRP,
As mentioned above, only the highly brittle fibers break, and the effect of correcting the opening is small. This is because the texture of the fabric is fixed and restricted by pressing, which restricts the movement of fibers, and the theory of opening correction is different between malleable and non-malleable materials.
更にこの様な目開き矯正は、ＦＲＰの材料の一つである
クロスプリプレグ（強化繊維から成る織物にマトリック
ス樹脂を含浸せしめた状態）に於いても要求される。Furthermore, such eye opening correction is also required for cross prepreg (a fabric made of reinforcing fibers impregnated with matrix resin), which is one of the materials for FRP.

の進行方向に逆らって移動することと同じ現象である。In FIG. 2, a number of freely rotatable spherical bodies 4 are placed in a space in a mesoche-like object 5 for fixing the position of the spherical bodies 4. A fabric 6 whose opening is to be corrected is placed below the large number of spherical bodies 4, and the fabric 6 is pulled in the direction of the arrow 7. At this time, the spherical body 4 rotates in the direction of the arrow in the sphere in FIG. This phenomenon occurs when the fabric 6 is rotated while the spherical body 4 rotates.
This is the same phenomenon as moving against the direction of travel.

とも出来る。At this time, the warp 1 and weft 2 constituting the fabric 6 are subjected to a dividing action at the lower apex of the spherical body 4, resulting in the expansion [[1 effect]. This widening effect increases as the diameter of the spherical body 4 becomes smaller and as the pressure of the spherical body 4 on the fabric increases, but in the illustrated example, the pressure is generated by the weight of the spherical body 4 itself. If higher pressure than this is required,
The pressure can be adjusted by a pressure belt or the like that touches the top of the spherical body 4 and moves in the opposite direction to the fabric 6. If the spherical body 4 is a steel ball, a magnetic sheet or the like is placed at the bottom of the fabric 6. Pressure can also be generated by placing

図のＡ−Ａ′断面図である。The present invention can be more effectively embodied by the apparatus shown in FIGS. 4 and 5. In FIG. 4, a cylindrical body (hereinafter abbreviated as roll) 8 has a large number of spherical bodies 4 on its surface, and the spherical bodies 4 are connected to a carrier 9.
The rollers are combined without coming off the roll surface, and rotate together on the roll surface. This structure is similar to, for example, the structure of a pole guide bearing for a guiset. A rotating body having such a structure in which the spherical body 4 and the roll 8 are combined is hereinafter abbreviated as a straightening roll. ) is combined with the bottom roll 10, and the fabric 6 to be straightened is held between the spherical body 4 and the bottom roll IO and placed under slight pressure. In this state, when the surface speed of the bottom roll 10 and the speed of the fabric 6 in the direction of the arrow are made to be the same, and the surface speed of the roll 8 is made higher than the speed of the fabric 6, the spherical body 4 rotates on the surface of the fabric. The large number of spherical bodies 4 rotate as one around the roll 80 in the direction of the arrow 11. The state of the spherical body 4 and the fabric 8 at this time is shown in FIG. Figure 5 is the 4th
It is a sectional view taken along the line AA' in the figure.

るために凹凸ロール表面で織物を擦過する時には織物を
構成する繊維に損傷を与えやすい。The woven fabric 6 moves from the front side of the page to the back side, and the spherical bodies 4 rotate and move the warp 1 and weft 2 constituting the woven fabric 6 on the surface thereof, causing an effect of widening the warp 1 and the weft 2. By the way, when pressing a fabric on an uneven surface, the width of the yarn is larger than when pressing a fabric on a flat surface. The reason for this is that, as mentioned above, pressing on a plane merely defines the structure of the fabric. On the other hand, when pressing is performed on a surface having an uneven surface, the texture of the fabric is not restricted in the concave portions, so there is room for the threads or single fibers that make up the fabric to move, and the opening can be easily corrected. However, simply pressing with a textured roll has only a few points of action (it is not possible to process the fabric in a short time.Also, in order to increase the number of points of action, when the fabric is rubbed on the surface of the textured roll, it is difficult to process the fabric). Easy to damage fibers.
これに対し本発明の如く織物表面を球状体が加圧接触状

しい装置である。On the other hand, when the spherical body rotates and moves on the surface of the fabric in a pressurized contact state as in the present invention, the greatest advantage is that damage to the fibers can be kept to a minimum and the number of points of action can be increased. Therefore, in the mechanism shown in FIG.
The rotation speed of the roll should be as high as possible, and the spherical body 4 on the roll surface should be
It is preferable that the rollers are arranged so as to give a uniform effect in the longitudinal direction of the roll 8 (in the width direction of the fabric), similar to the device shown in FIG. This apparatus is more preferable than the apparatus shown in FIG. 2 because it can apply more points of action to the fabric.
なお、球状体４の移動方向は特に限定するものではない
が、被矯正織物の進行方向と逆方向に設定することが好
ましい。Note that the moving direction of the spherical bodies 4 is not particularly limited, but it is preferably set to the opposite direction to the traveling direction of the fabric to be straightened.

For example, as shown in FIG. 6, the fabric 6 is guided by guide rolls 12, 13 and rolled over the straightening roll shown in FIG. At this time, by applying tension to the fabric 6, it is possible to create a pressurized contact state between the fabric 6 and the spherical body 4.

用点に運ばれる。Furthermore, the present invention can also be implemented by the apparatus shown in FIG. The fabric 6 moves on the surface of the roll 14 in the direction of the arrow. On the other hand, the spherical body 4 is pressed against the fabric 6 and rotated by a belt 15 arranged substantially concentrically with the roll 14. After the spherical body 4 imparts a straightening effect to the fabric 6, it falls freely from the upper part of the belt 15, is guided by a guide surface formed on the inner surface of the casing, and is conveyed by the belt 15 to the point of action again.

出来る。As described above, the present invention is characterized in that a large number of spherical bodies are rotated and moved in pressurized contact with the surface of a fabric, and is not limited to the above-mentioned example of the apparatus. In addition,
The dimensions of the spherical bodies 4 are selected depending on the specifications of the fabric to be straightened, but generally a diameter of about 21mm to 10mm gives good results. Further, although steel balls are often used as the material, plastic balls may also be used in some cases.

ことが必要である。In addition, while the explanation has been made regarding a normal reinforcing fabric (generally referred to as greige fabric) that does not contain a matrix resin as the fabric to be straightened, the present invention also applies to cross prepregs containing a matrix resin. However, in this case, it is necessary to interpose a plastic film or the like between the cross prepreg and the spherical bodies to prevent the resin from moving to the spherical bodies.
