The present invention relates to a method for producing a synthetic resin billiard cue, a glass cloth (including a carbon cloth) is rolled on a taper rod while applying a resin liquid to dry the common glass rod (Gla) ss Rod (including carbon rod) is used as a counterpart to the cue, a wooden core is built in the center line of the glass rod, and urethane is provided with foamability in the space formed between the glass rod and the core. In filling (Urethane Form Fillers), in particular, the urethane 훰 filling is injected into the large diameter side of the glass rod, the filling operation while sucking the air in the glass rod on the small diameter side.

As described above, the fine bubble layers formed in the urethane 훰 filler filled between the glass rod and the core and cured by the foam molding process form a bubble group in the longitudinal direction of the glass rod, and the fibrous roots are made of the urethane 훰 filler between the bubble groups. The glass rods are also formed in the longitudinal direction of the glass rod, and as described above, the bubble groups formed in the longitudinal direction of the glass rod become a urethane 훰 tissue gradually formed in the thin diameter as it goes from the large diameter side to the small diameter side of the glass rod. Since it is similar to wood, the synthetic billiard cue can obtain the same effect as the wood cue because the concentration of force when hitting the ball and the absorbing power that absorbs the repulsive force reflected by the cue at the moment of hitting.

The origin of billiards is an indoor game play originated in Europe. It requires 10 cues to hit the ivory ball. The length of billiards is 146-148cm and the weight is 15-20 depending on the game. . The cue is composed of opponents and bases. The opponents are usually made of wood, and the bases only function to adjust the weight regardless of the material.

Looking at the tissue of the tree used as described above is composed of a solid long-fiber tissue and soft capillary tissue in the longitudinal direction is excellent in the absorption effect of the repulsive force (shock wave) due to the concentration of force and hitting the billiard ball hit. When hitting the ball with the ball, the diameter of the tap area of the ball is usually 14 mm, and the maximum impact value at the time of hitting is close to 1 ton. If it is made of solid wood, the batik can not absorb the impact blood, so the repulsive force (shock wave) is transmitted to the elbow as it is.

As mentioned above, the maple tree is particularly preferred for the long-term experience of billiards and the absorption of other shock waves in the concentration and repulsion of batting forces. The Britannica dictionary (Britann ica encyclopedia) You can also see. Maple trees are suitable to be grown in coniferous areas such as Canada, and are suitable for the maple trees. Qiu's maple trees have reached the end of their supply. In particular, Korea's total dependence on imports. Maple trees are popular because they are expensive to use. There is a problem.

Therefore, in recent years, billiard cues are manufactured and used in inexpensive aluminum and synthetic resin instead of wood. For example, billiards of Korean Utility Model No. 82-2224, which consists of a sponge bar inserted in an aluminum tube, constitutes a counterpart. You can see the kyuwoo, but you can't expect the same weight as wood from them, and it is composed of non-ferrous metal, which can be used for a long time, but it can't extinguish shock waves that are close to 1 ton. The shock wave can not exclude the fact that it causes an abnormality in the body.

In addition, the prefabricated billiard body which compulsively filled the polyurethane resin in the synthetic resin (glass fiber) tube to function as a shock absorber has been registered as Utility Model No. 89-9711, but the structure of the filled polyurethane resin is of the same density. Although it has a specific gravity similar to wood, it has a similar repulsion and absorbing power when hitting the ball. Therefore, the concentration of force and resilience of shock waves due to repulsion are not good, and it is not obtained by professional billiards. It has been found that a preferred synthetic resin billiard cue is needed.

In addition, the above-mentioned drawbacks are solved, and the billiard cue excellent in the feel and action of the batting ball is selected as a utility layer registration application No. 85-14652, in particular, which has a filling layer similar to that of the wood fiber and has a specific gravity similar to that of wood. In addition, it has been found that the composition of the filler with a specific gravity similar to that of wood, in particular, requires the production of an inseparable method of injecting the filler and releasing the air (vacuum degree).

As described in the Utility Model Application No. 85-14652, the present invention gradually expands the bubble group while going to the upper end of the opponent constituting the cue while having a specific gravity surpassing that of wood by making the bubble group of the urethane filler filling in the longitudinal direction. The narrow and urethane fibrous tissue has been expanded to create a manufacturing method of a cue that can provide a synthetic resin cue that can be harmonized well with the concentration of shock and absorption of shock waves. The above is as follows.
