Description

[Technical Field]

[0001] The present invention relates to the technical field of billiards, and in particular to a billiard table, its clasp and mounting method. [Background technology]

[0002] Billiards has become a global sport. Billiard tables are an essential piece of equipment infrastructure for various billiards games. A billiard table consists of a table top, a rim, and support legs, with the table top and rim fixedly connected and resting on the ground via the support legs. The table top typically consists of several joined stone slabs and a cloth laid on the surface of the slabs. The cloth is a rectangular, fluffy fabric woven from pure wool or a blend of wool and synthetic fibers. The front of the cloth must be extremely flat, with the nap professionally trimmed to keep it short and flat, and the back must be untrimmed. The warp and weft threads of the fluffy yarn must be extremely uniform in thickness and aligned vertically and horizontally. Failure to do so will affect the stability of the ball's roll and cause it to change direction. This is quite different from cloth for clothing, and competitive cloth is very expensive. The frequent rolling of the ball and its high-speed friction, the constant pushing and rubbing by the player's hands, the constant stabbing by the cue head, and the ball bouncing and falling and hitting the lining make the lining very susceptible to wear. The worn lining gradually wears down, and microscopic irregularities appear in the warp and weft threads, affecting the stability of the ball's rolling, making the ball faster, more difficult to control, and in the worst case, causing it to change direction, which can seriously affect the enjoyment of the game and the player's performance.

[0003] A typical home billiard table is used less frequently and wears out slowly, but billiard tables in billiard clubs and bars are used more frequently and wear out faster, generally needing to be replaced at least three or four times a year.

[0004] In the prior art, there are two main methods for laying rags on a stone slab base. One is the nailing method, and the other is the gluing method. In both methods, rectangular rags slightly larger than the slab are laid evenly over the surface. The difference is that in the nailing method, the rags are nailed to the bottom or sides of a narrow wooden board at the bottom of the base slab, while in the gluing method, the rags are glued directly to the sides of the base slab without attaching a narrow wooden board to the bottom of the slab.

[0005] First, in the nailing method, a screw or U-shaped nail for the lining is nailed into a narrow wooden board under the slate base, and the narrow wooden board under the slate base is fastened with bolts around the periphery of the back of the slate base. When nailing the lining with a screw, a strong craftsman first pulls the lining with one hand, then reverses his wrist to press down on the base. Next, he receives the screw from his right hand with his thumb and index finger, piercing the tip of the nail into the lining and wooden board under the slate base to position it, and then uses a hammer with his other hand to quickly drive the screw into the board. This method places great demands on the craftsman's strength, requiring him to use his strength to pull the lining; otherwise, a lining that is not tightly tensioned will easily wrinkle when rubbed by hand, affecting ball speed. Furthermore, a lining that is too loose will easily tear when the cue head is dropped. If the craftsman's arms do not have sufficient strength, he will only be able to wear a small number of linings each day. Therefore, to improve efficiency and compensate for lack of strength, two engineers often need to complete the work together. One engineer holds the platform with both hands, while the other hammers the nail. U-shaped nails can be driven with a pneumatic nail gun or a manual nail gun instead of a hammer, which improves nailing efficiency.

[0006] The nailing method has the following drawbacks: First, when nailing the six arc-shaped pockets on the slate base, especially the two side pockets, the straight edge of the lining must fit snugly against the arcs on the sides of the slate base. However, because the length of the lining's straight edge is obviously not equal to the length of the arcs on the slate, applying significant pressure to the straight edge of the lining will not allow it to fit snugly against the arcs on the slate. Poor nailing results in the middle expanding, preventing it from fitting snugly against the arc-shaped pockets. This expansion not only affects the ball's entry into the pocket, but also makes it more likely that a strong strike will cause the ball to bounce off the arcs on the slate after hitting the pocket, resulting in it being easily ejected by the tightly tensed lining. To prevent this expansion, the lining of one side pocket is typically first secured at the center of the arcs, followed by the arcs on the other side pocket. In this case, the flat surface of the slab on both sides of the side pockets shows pronounced horizontal wrinkles of a certain height, which can be eliminated simply by pulling the cloth closer to the side. The closer to the arc, the greater the pulling force, and the greater the deformation of the cloth. Therefore, it is necessary to strengthen the effect of pulling the cloth in the more distant corner pockets to remove the wrinkles. In other words, the effect of using horizontal pulling force to eliminate semicircular wrinkles is not ideal. Due to uneven pulling force, the cloth on the table surface at the pockets is not flat. Even on the British-made billiard table used by Ding Junhui when he won the championship, the British fitting technician was unable to avoid the wrinkles in the side pockets after fitting; only after spraying British wool softener and rubbing it with his hand did the wrinkles improve slightly.

[0007] Furthermore, without experience, wrinkles often occur on the arcs of the stone table surface of the four corner pockets. This not only affects the aesthetic appearance, but also increases the height of the cushion, affecting the normal use of the billiard table. To prevent wrinkles and bulges, professional training and skilled technicians are required.

[0008] Second, the U-shaped nailing method requires either a pneumatic or manual nail gun. Pneumatic nail guns are labor-saving and highly efficient, but they require a gas source, i.e., an air pump. Billiard clubs generally do not have dedicated air pumps, making it inconvenient for professional technicians to carry them. Furthermore, the loud noise of the air pump disrupts business operations. Clubs generally require professional technicians to work after midnight, and technicians are reluctant to stay up late for long periods of time. Manual mechanical nail guns are labor-intensive, prone to damage, have a short lifespan, require frequent replacement, and are unable to drive nails into hard wood with low force. Most significantly, prolonged use of a manual nail gun places strain on the technician's hand while holding the nail gun, causing irreversible damage.

[0009] Third, wooden boards must be installed around the bottom of the stone base for nailing. These boards also have certain requirements. They must be soft, free of chips, and easy to nail. Such boards are generally expensive. Also, 36 mounting holes must be pre-drilled on the edges of the stone, and the holes must be deeply chamfered.

[0010] Fourth, when nailing, the lashing at the nailed area is fixed, and the part not fixed by the nail rebounds due to the action of elastic force, resulting in uneven tension of the elastic force. The larger the nail pitch, the more pronounced the rebound becomes, and a clear wave shape can be seen.

[0011] 2. Adhesion method The adhesive method is relatively easy to install. First, brush structural adhesive onto the sides of the base stone slab and the surfaces of the six pockets. Then, fold the four edges of the cloth over, place the front of the cloth edge against the front of the cloth laid on the base stone slab, and turn the other side up. Then, brush the structural adhesive evenly onto the sides of the slab and a width slightly wider than the arc of the pockets. Once the adhesive has dried, 1) first glue the cloth of one side pocket to the slab. 2) Glue the cloth of the other side pocket a little more firmly. 3) Glue the cloth of one corner pocket. 4) Glue the cloth of the other corner pocket even more firmly. 5) Glue the cloth of the other two corner pockets as above. 6) Pull flat and remove all the straight hedges of the pockets.

[0012] Disadvantages of adhesive methods: When replacing a new rag, the adhesive layer on the surface of the old rag is thick due to the adhesive's viscosity. When replacing the rag, some of the rag's fluff will adhere to the slate. After several replacements, an unevenly thick mixture of structural adhesive and rag fluff will form. As replacements increase, the mixture thickness can reach 1-2mm. As the thickness of both sides of the slate increases, the original slate becomes longer, the corner pockets become larger, and the ball's accessibility changes. Furthermore, the uneven buildup layer formed by the mixture destroys the 90° corners of the cushion's mounting surface, causing them to expand and contract, affecting the cushion's elasticity. The unevenness of the tough mixture layer destroys the cushion's straightness. In other words, using the adhesive method can destroy the performance of the billiard table, which is unacceptable, especially for match-style billiard tables. The buildup layer, made by mixing adhesive and rag, is extremely tough under the pressure of several months of screw tightening on the cushion, making it extremely difficult to completely remove mechanically and restore the original flatness of the stone slab edge, and even chemical removal is difficult. Furthermore, the nap on the back of the rag is not sufficiently adhesive, so it cannot withstand relatively large tensile forces, and the rag is not as tight as when nailed. A loose rag affects the ball's movement speed, and it is necessary to tighten the cushion immediately after gluing to press the rag against the cushion and prevent it from loosening.

[0013] The biggest drawback of both nailing and adhesive installation methods is that they require specialized, skilled technicians. For example, at our factory, over 200 installation technicians travel to various locations around Japan every year. In Europe and the United States, labor costs are high, so there are clubs that replace rags en masse, and every year they fly specialized technicians from Asia, where labor costs are lower, to install the rags.

[0014] How to improve the method for installing billiard table cloth, ensure that the warp and weft threads are as straight as possible vertically and horizontally, ensure that the nap flows as straight as possible toward the corner pockets, improve the quality and speed of installing billiard table cloth, reduce the difficulty of installation, and reduce the need for a large number of professional installers is a difficult issue in promoting the development of billiards. Summary of the Invention [Problem to be solved by the invention]

[0015] In view of these circumstances, the present invention provides a billiard table, its lining, and an installation method.

When tightening the cloth, the method further includes overlapping the vertical attachment detection line with the upper ridge line of the long side of the base stone slab, and overlapping the horizontal attachment detection line with the upper ridge line of the short side of the base stone slab.

[0019] Furthermore, both the longitudinal attachment detection line and the transverse attachment detection line are formed by a numerically controlled wire drawing machine.

[0020] The method further includes step 6 of peeling off the second protective film of the reinforcing double-sided tape, adhering the second adhesive surface to the front numerically controlled adhesive layer of the pocket and the bottom surface of the base stone slab, and adhering the front surface of the cloth adhered to the bottom surface of the base stone slab with the arc-shaped notch to the bottom surface of the base stone slab, thereby preventing the cloth from loosening.

[0021] Furthermore, both the numerically controlled adhesive layer and the front numerically controlled adhesive layer are formed by automatically spraying with a numerically controlled adhesive applicator.

[0022] According to the present invention, there is further provided a billiard table using the method for attaching the clasp provided by the above technical means. The billiard table includes a base stone slab, clasp, and double-sided tape, The cloth is laid on the base stone slab, and a numerically controlled adhesive layer is provided on the four periphery of the surface opposite to the surface attached to the base stone slab. The cloth has linear stress relief notches and oblique stress relief notches at positions corresponding to the side pockets of the base stone slab, and oblique stress relief notches are provided at positions corresponding to the corner pockets of the cloth, and the linear stress relief notches have a centering function. The double-sided tape includes a first adhesive surface and a second adhesive surface, the first adhesive surface is attached to the four peripheries of the side and bottom surfaces of the base stone slab, and the second adhesive surface is attached to the numerically controlled adhesive layer and is used to attach the clasp to the base stone slab.

[0023] Furthermore, the base stone slab is provided with an arc-shaped notch that forms a pocket, and a front numerically controlled adhesive layer is provided on the front surface of the cloth surrounding the arc-shaped notch, and the front numerically controlled adhesive layer and the bottom surface of the base stone slab are adhered together with reinforcing double-sided tape.

[0026] Furthermore, the vertical attachment detection line and the horizontal attachment detection line are both formed by a straight line, a plurality of plotted points, or a plurality of line segments.

[0027] Furthermore, the color of the longitudinal attachment detection line and the transverse attachment detection line is different from the color of the cloth.

[0028] Furthermore, the cloth is cut by a numerically controlled laser cutting machine. [Effects of the Invention]

[0029] Beneficial effects 1. In the method of attaching a cloth to a base stone slab, not only is a numerically controlled adhesive layer applied around the back of the cloth, but double-sided tape is also applied around the sides and bottom of the base stone slab. The numerically controlled adhesive layer and double-sided tape are then used to secure the cloth to the sides and bottom of the base stone slab. The numerically controlled adhesive layer and double-sided tape are placed between the cloth and the base stone slab, preventing direct contact between the cloth and the base stone slab. Therefore, by attaching the cloth to the base stone slab with the numerically controlled adhesive layer and double-sided tape, the fuzz of the cloth is prevented from adhering to the base stone slab. The adhesive strength between the cloth and the base stone slab is increased by adding a numerically controlled adhesive layer on the back of the cloth, with a width that matches the second adhesive surface on the base stone slab. Because the fuzz on the back of the cloth is a floating layer, the amount of adhesive is small after it is attached to the double-sided tape, resulting in weak adhesion. Because the tensile strength that can withstand the loose fluff on the backside is very small, the cloth easily rebounds after being glued. The rebound loosens the cloth on the base stone slab, affecting the ball's speed. Therefore, by applying a numerically controlled adhesive layer with structural adhesive properties to the backside of the cloth and integrating the numerically controlled adhesive layer with the base fabric woven from the warp and weft of the cloth, the adhesive strength between the cloth and the double-sided tape is significantly increased, effectively solving the problem of cloth rebound. Furthermore, because the first adhesive surface of the double-sided tape is pressure-sensitive and does not stain the bonded surface after peeling, the problem of the cloth becoming thicker as it is bonded to the base stone slab and the fluff of the cloth is solved.

[0030] 2. In the method for attaching the lining of the present invention, linear stress relief notches and oblique stress relief notches are provided on the lining at positions corresponding to the side pockets of the base stone slab. The linear stress relief notches have a centering function. The overlapping of the linear stress relief notches with the center line of the base stone slab makes it easy to align the lining. The linear stress relief notches and oblique stress relief notches divide the lining at each pocket location. The notches relieve stress on the lining when fastening it to the pocket of the base stone slab, allowing the lining to easily fit into the arc-shaped pocket of the base stone slab and firmly adhere to the base stone slab without wrinkles. Compared to the nailing method, the horizontal wrinkles in the cloth are significantly reduced, unevenness of the cloth at the pockets is avoided, the amount of stonework required to machine 30 φ8×50 bolt holes on the backside of each billiard table and 30 φ15 counterbores on the frontside is reduced, and the 0.002m used to nail the cloth with U-shaped nails is reduced. 3 Based on our factory's production capacity of 30,000 units, this not only saves a large amount of high-quality cork material every year, but also reduces the workload of installing wooden boards on site.

[0031] 3. According to the method for attaching the lining of the present invention, the surface of the lining is provided with a longitudinal attachment detection line extending along the length of the lining and a transverse attachment detection line extending along the width of the lining. Because the attachment detection lines, parallel or perpendicular to the center line of the lining, are pre-drawn, anyone pulling the lining can align it with the upper ridge of the edge of the base slab with both hands, balancing the pulling force on the lining and ensuring that the warp and weft threads are straight both vertically and horizontally. In this way, the nap directions of the lining, which have both reverse and normal pile orientations, are aligned, ensuring stable ball movement and less change in direction. This significantly improves the quality of the lining.

[0032] 4. In the fabric installation method of this invention, the CNC adhesive layer on the fabric and the CNC adhesive layer on the front can be automatically sprayed using a CNC adhesive applicator. The CNC adhesive applicator can accurately control the width, thickness, and shape of the adhesive, reducing the amount of adhesive used, ensuring adhesive quality, significantly improving work efficiency, and saving labor. When applying structural adhesive manually, it is difficult to accurately control the width and amount of adhesive.

[0033] 5. The flannel used in the flannel attachment method of the present invention is cut using a numerically controlled laser cutter. The numerically controlled laser cutter can accurately cut the pocket arc, linear stress relief notches, and oblique stress relief notches. The use of a numerically controlled laser cutter in conjunction with a numerically controlled adhesive applicator allows for efficient assembly line production.

[0034] 6. The front of the rag is provided with a vertical detection line for alignment with the long edge of the base stone slab and a horizontal detection line for alignment with the short edge of the base stone slab. Both the vertical and horizontal detection lines are formed directly by a numerically controlled drawing machine, which has the advantages of accurate drawing position, high reliability, and efficiency. The combination of a numerically controlled drawing machine, a numerically controlled laser cutting machine, and a numerically controlled adhesive applicator enables an efficient assembly line for the rag, facilitating industrial production and reducing costs.

[0035] 7. The flannel of the present invention is cut using a numerically controlled laser cutter. By using a numerically controlled laser cutter, it is possible to cut according to the actual shape formed after installation. Since the flannel cut using a numerically controlled laser cutter does not have any excess parts that need to be manually removed after installation, the workload of the installer who has to trim the excess flannel after installation is reduced.

One oblique stress relief notch 11 is provided at a position corresponding to the corner pockets 9 of the base slab 1 of the cloth 2.

[0040] Step 2 S20: Peel off the first protective film from the double-sided tape 6, and adhere the first adhesive surface of the double-sided tape 6 to the sides and four peripheries of the bottom surface of the base stone slab 1. After peeling off the first protective film from the double-sided tape 6, the first adhesive surface of the double-sided tape 6 is exposed, and the double-sided tape 6 is adhered to the sides and four peripheries of the bottom surface of the base stone slab 1 via the first adhesive surface.

[0041] Step 3 S30: Lay the cloth 2 on the base stone slab 1, with the numerically controlled adhesive layer 5 of the cloth 2 facing the base stone slab 1. As shown in Figure 4, during the process of laying the cloth 2 on the base stone slab 1, the length direction of the cloth 2 is aligned with the length direction of the base stone slab 1, the cloth 2 covers the top of the base stone slab 1, and the four edges of the cloth 2 cover the four edges of the base stone slab 1.

[0042] Step four S40: Peel off the second protective film of the double-sided tape 6. The second protective film of the double-sided tape 6 is located on the outside, and after the second protective film is peeled off, the second adhesive surface of the double-sided tape 6 is exposed.

[0043] Step five S50: The cloth 2 is tightened, and the numerically controlled adhesive layer 5 of the cloth 2 is adhered to the second adhesive surface of the double-sided tape 6. The cloth 2 covering the base stone slab 1 is tightened, and the numerically controlled adhesive layer 5 of the cloth 2 is adhered to the second adhesive surface of the double-sided tape 6, and the cloth 2 is adhered to the sides and bottom of the base stone slab 1 via the double-sided tape 6 and the numerically controlled adhesive layer 5 of the cloth 2, thereby fixing and attaching the cloth 2 to the base stone slab 1.

[0044] Example 2 As shown in FIG. 2, this embodiment provides a method for attaching a billiard table cloth 2 to the billiard table. The billiard table includes a table slab 1, a cloth 2, and a double-sided tape 6 for adhering the cloth 2 to the table slab 1. The double-sided tape 6 has a first adhesive surface with pressure-sensitive adhesive, a second adhesive surface with structural adhesive, a first protective film covering the first adhesive surface, and a second protective film covering the second adhesive surface. The table slab 1 has an arc-shaped notch that forms a pocket. The billiard table has a total of six pockets, including two side pockets 8 and four corner pockets 9. The four corner pockets 9 are located at the four corners of the billiard table, and the two side pockets 8 are located in the center. The cloth 2 has a back surface that is attached to the surface of the table slab 1, a numerically controlled adhesive layer 5 that is attached to the sides and bottom of the table slab 1, and a front numerically controlled adhesive layer 7 that is attached to the reinforcing double-sided tape. This attachment method includes the following steps.

[0045] Step 1 S10: As shown in Figures 4 and 5, a numerically controlled adhesive layer 5 is formed around the back of the cloth 2, with linear stress relief notches 10 and oblique stress relief notches 11 formed at positions corresponding to the side pockets 8 of the cloth 2, and oblique stress relief notches 11 formed at positions corresponding to the corner pockets 9 of the cloth 2. Three notches are formed at the center of the long side of the cloth 2, i.e., at a position corresponding to the side pockets 8 of the base slab 1 of the cloth 2, including one linear stress relief notch 10 and two symmetrically arranged oblique stress relief notches 11. One oblique stress relief notch 11 is formed at a position corresponding to the corner pockets 9 of the base slab 1 of the cloth 2. The linear stress relief notch 10 has a centering function. The linear stress relief notch 10 notches not only relieve stress but also serve to center the base slab 1 and align the linear stress relief notch 10 with the center line of the base slab 1. The front of the cloth 2 is provided with four longitudinal attachment detection lines 3 extending along the length of the cloth 2 and two transverse attachment detection lines 4 extending along the width of the cloth 2. The longitudinal attachment detection lines 3 and the transverse attachment detection lines 4 may be straight lines, formed from a plurality of plotted points spaced apart along a straight line, or formed from a plurality of line segments arranged along a straight line. The longitudinal attachment detection lines 3 and the transverse attachment detection lines 4 can be formed using a numerically controlled wire drawing machine. That is, the longitudinal attachment detection lines 3 and the transverse attachment detection lines 4 are drawn on the cloth 2 using a numerically controlled wire drawing machine. For ease of distinction, the longitudinal attachment detection lines 3 and the transverse attachment detection lines 4 may be a different color from the cloth 2. For example, if the cloth 2 is green, the longitudinal attachment detection lines 3 and the transverse attachment detection lines 4 may be straight lines, plotted points, line segments, or patterns in a color such as white, gold, red, or black. The back surface of the cloth 2 is attached to the base stone slab 1, and the opposite surface faces away from the base stone slab 1. That is, the surface of the cloth 2 that is attached to the base stone slab 1 is the back surface, and the front surface is in contact with the ball and allows the ball to roll along it. A numerically controlled adhesive layer 5 is provided on the back surface of the cloth 2. Four vertical attachment detection lines 3 are each parallel to the long sides of the cloth 2 and correspond one-to-one to the upper ridge lines of the long sides of the base stone slab 1.That is, two vertical attachment detection lines 3 are provided near each long side of the cloth 2, and the extensions of the two vertical attachment detection lines 3 overlap. Two horizontal attachment detection lines 4 are provided perpendicular to the vertical attachment detection lines 3 and correspond one-to-one to the short sides of the cloth 2. That is, one horizontal attachment detection line 4 is provided near each short side of the cloth 2. By providing the horizontal attachment detection lines 4 and the vertical attachment detection lines 3, after the cloth 2 is attached to the base stone slab 1, the horizontal attachment detection line 4 overlaps with the upper ridge line of the short side of the base stone slab 1, and the vertical attachment detection line 3 overlaps with the upper ridge line of the long side of the base stone slab 1. That is, the two horizontal attachment detection lines 4 and the four vertical attachment detection lines 3 limit the attachment position of the cloth 2. The horizontal attachment detection lines 4 and the vertical attachment detection lines 3 can assist in the attachment of the cloth 2 and can also detect the attachment quality of the cloth 2.

[0046] Step 2 S20: Peel off the first protective film from the double-sided tape 6, and adhere the first adhesive surface of the double-sided tape 6 to the sides and four peripheries of the bottom surface of the base stone slab 1. After peeling off the first protective film from the double-sided tape 6, the first adhesive surface of the double-sided tape 6 is exposed, and the double-sided tape 6 is adhered to the sides and four peripheries of the bottom surface of the base stone slab 1 via the first adhesive surface.

[0047] Step 3 S30: Lay the cloth 2 on the base stone slab 1, with the numerically controlled adhesive layer 5 of the cloth 2 facing the base stone slab 1. In the process of laying the cloth 2 on the base stone slab 1, align the length direction of the cloth 2 with the length direction of the base stone slab 1, cover the top of the base stone slab 1 with the cloth 2, and cover the four sides of the base stone slab 1 with the cloth 2.

[0048] Step four S40: Peel off the second protective film of the double-sided tape 6. The second protective film of the double-sided tape 6 is located on the outside, and after the second protective film is peeled off, the second adhesive surface of the double-sided tape 6 is exposed.

[0049] Step 5 S50: The cloth 2 is tightened, aligning the vertical mounting detection line 3 with the upper ridge of the long side of the base stone slab 1 and the horizontal mounting detection line 4 with the upper ridge of the short side of the base stone slab 1, and the numerically controlled adhesive layer 5 of the cloth 2 is adhered to the second adhesive surface of the double-sided tape 6. The cloth 2 is tightened to cover the base stone slab 1. During the tightening process, the vertical mounting detection line 3 and the horizontal mounting detection line 4 are used as reference to adjust the position of the cloth 2 so that the cloth 2 is symmetrical in both the horizontal and vertical directions. The horizontal direction of the cloth 2 is the extension direction of the short side of the base stone slab 1, and the vertical direction of the cloth 2 is the extension direction of the long side of the base stone slab 1. The numerically controlled adhesive layer 5 of the cloth 2 is adhered to the second adhesive surface of the double-sided tape 6, and the cloth 2 is adhered to the bottom surface of the base stone slab 1 via the double-sided tape 6 and the numerically controlled adhesive layer 5 of the cloth 2, thereby securing and attaching the cloth 2 to the base stone slab 1.

[0050] Example 3 As shown in FIG. 3, this embodiment provides a method for attaching a billiard table cloth 2 to the billiard table. The billiard table includes a table slab 1, a cloth 2, and a double-sided tape 6 for adhering the cloth 2 to the table slab 1. The double-sided tape 6 has a first adhesive surface with pressure-sensitive adhesive, a second adhesive surface with structural adhesive, a first protective film covering the first adhesive surface, and a second protective film covering the second adhesive surface. The table slab 1 has an arc-shaped notch that forms a pocket. The billiard table has a total of six pockets, including two side pockets 8 and four corner pockets 9. The four corner pockets 9 are located at the four corners of the billiard table, and the two side pockets 8 are located in the center. The cloth 2 has a back surface that is attached to the surface of the table slab 1, a numerically controlled adhesive layer 5 that is attached to the sides and bottom of the table slab 1, and a front numerically controlled adhesive layer 7 that is attached to the reinforcing double-sided tape. This attachment method includes the following steps.

[0051] Step 1 S10: As shown in Figures 4, 5, and 6, a numerically controlled adhesive layer 5 is formed around the back of the cloth 2. Linear stress relief notches 10 and oblique stress relief notches 11 are formed at positions corresponding to the side pockets 8 of the cloth 2, and oblique stress relief notches 11 are formed at positions corresponding to the corner pockets 9 of the cloth 2. Three notches are formed at the center of the long side of the cloth 2, i.e., at a position corresponding to the side pockets 8 of the base slab 1 of the cloth 2, including one linear stress relief notch 10 and two symmetrically arranged oblique stress relief notches 11. One oblique stress relief notch 11 is formed at a position corresponding to the corner pockets 9 of the base slab 1 of the cloth 2. The linear stress relief notch 10 has a centering function. The linear stress relief notch 10 notches not only relieve stress but also serve to center the base slab 1 and align the linear stress relief notch 10 with the center line of the base slab 1. A front numerically controlled adhesive layer 7 is provided on the front surface of the cloth 2 surrounding the arc-shaped notch. The front surface of the cloth 2 is provided with four longitudinal attachment detection lines 3 extending along the length of the cloth 2 and two transverse attachment detection lines 4 extending along the width of the cloth 2. The longitudinal attachment detection lines 3 and the transverse attachment detection lines 4 may be straight lines, formed from a plurality of plotted dots spaced apart along a straight line, or formed from a plurality of line segments arranged along a straight line. The longitudinal attachment detection lines 3 and the transverse attachment detection lines 4 can be formed using a numerically controlled line drawing machine. That is, the longitudinal attachment detection lines 3 and the transverse attachment detection lines 4 are drawn on the cloth 2 using a numerically controlled line drawing machine. For ease of distinction, the longitudinal attachment detection lines 3 and the transverse attachment detection lines 4 may be a different color from the cloth 2. For example, if the cloth 2 is green, the longitudinal attachment detection lines 3 and the transverse attachment detection lines 4 may be straight lines, plotted dots, line segments, or patterns in a color such as white, gold, red, or black. The back surface of the cloth 2 is attached to the base stone slab 1, and the front surface is in contact with the ball so that the ball can roll along it. A numerically controlled adhesive layer 5 is provided on the back surface of the cloth 2. Four vertical attachment detection lines 3 are parallel to the long sides of the cloth 2 and correspond one-to-one to the upper ridges of the long sides of the base stone slab 1.That is, two vertical attachment detection lines 3 are provided near each long side of the cloth 2, and the extensions of the two vertical attachment detection lines 3 overlap. Two horizontal attachment detection lines 4 are provided perpendicular to the vertical attachment detection lines 3 and correspond one-to-one to the short sides of the cloth 2. That is, one horizontal attachment detection line 4 is provided near each short side of the cloth 2. By providing the horizontal attachment detection lines 4 and the vertical attachment detection lines 3, after the cloth 2 is attached to the base stone slab 1, the horizontal attachment detection line 4 overlaps with the upper ridge line of the short side of the base stone slab 1, and the vertical attachment detection line 3 overlaps with the upper ridge line of the long side of the base stone slab 1. That is, the two horizontal attachment detection lines 4 and the four vertical attachment detection lines 3 limit the attachment position of the cloth 2. The horizontal attachment detection lines 4 and the vertical attachment detection lines 3 can assist in the attachment of the cloth 2 and can also detect the attachment quality of the cloth 2. As shown in Fig. 4, the base stone slab 1 includes two side pockets 8 and four corner pockets 9 at the four corners. As shown in Fig. 6, a front numerically controlled adhesive layer 7 is provided on the front surface of the cloth 2 around the side pockets 8 and corner pockets 9.

[0052] Step 2 S20: Peel off the first protective film from the double-sided tape 6, and adhere the first adhesive surface of the double-sided tape 6 to the sides and four peripheries of the bottom surface of the base stone slab 1. After peeling off the first protective film from the double-sided tape 6, the first adhesive surface of the double-sided tape 6 is exposed, and the double-sided tape 6 is adhered to the sides and four peripheries of the bottom surface of the base stone slab 1 via the first adhesive surface.

[0053] Step 3 S30: Lay the cloth 2 on the base stone slab 1, with the numerically controlled adhesive layer 5 of the cloth 2 facing the base stone slab 1. In the process of laying the cloth 2 on the base stone slab 1, align the length direction of the cloth 2 with the length direction of the base stone slab 1, cover the top of the base stone slab 1 with the cloth 2, and cover the four sides of the base stone slab 1 with the cloth 2.

[0054] Step four S40: Peel off the second protective film of the double-sided tape 6. The second protective film of the double-sided tape 6 is located on the outside, and after the second protective film is peeled off, the second adhesive surface of the double-sided tape 6 is exposed.

[0055] Step 5 S50: The cloth 2 is tightened, aligning the vertical mounting detection line 3 with the upper ridge of the long side of the base stone slab 1 and the horizontal mounting detection line 4 with the upper ridge of the short side of the base stone slab 1, and the numerically controlled adhesive layer 5 of the cloth 2 is adhered to the second adhesive surface of the double-sided tape 6. The cloth 2 is tightened to cover the base stone slab 1. During the tightening process, the vertical mounting detection line 3 and the horizontal mounting detection line 4 are used as reference to adjust the position of the cloth 2 so that the cloth 2 is symmetrical in both the horizontal and vertical directions. The horizontal direction of the cloth 2 is the extension direction of the short side of the base stone slab 1, and the vertical direction of the cloth 2 is the extension direction of the long side of the base stone slab 1. The numerically controlled adhesive layer 5 of the cloth 2 is adhered to the second adhesive surface of the double-sided tape 6, and the cloth 2 is adhered to the bottom surface of the base stone slab 1 via the double-sided tape 6 and the numerically controlled adhesive layer 5 of the cloth 2, thereby securing and attaching the cloth 2 to the base stone slab 1.

[0056] Step 6 S60: Peel off the second protective film from the reinforcing double-sided tape 6, and adhere the second adhesive surface to the front CNC adhesive layer 7 at the pocket and the bottom surface of the base stone slab 1. This adheres the front of the cloth 2, which is adhered to the bottom surface of the base stone slab 1 at the arc-shaped notch, to the bottom surface of the base stone slab 1, preventing the cloth 2 from loosening. As shown in Figure 6, one part of the double-sided tape 6 is adhered to the front CNC adhesive layer 7, and the other part is adhered to the bottom surface of the base stone slab 1. The adhesive surface of the double-sided tape 6 covers the front CNC adhesive layer 7 and the bottom surface of the base stone slab 1. Furthermore, the cloth 2 around the arc-shaped notch is adhered to the bottom surface of the base stone slab 1 for reinforcement, thereby making the connection between the cloth 2 around the pocket and the base stone slab 1 stronger and more reliable.

[0057] In the three embodiments of the method for attaching the cloth 2 to the base stone slab 1, not only is a numerically controlled adhesive layer 5 applied around the back of the cloth 2, but double-sided tape 6 is also attached to the four peripheries of the sides and bottom of the base stone slab 1, and the four peripheries of the cloth 2 are fixed to the sides and bottom of the base stone slab 1 by bonding the numerically controlled adhesive layer 5 and double-sided tape 6. Because the numerically controlled adhesive layer 5 and double-sided tape 6 are provided between the cloth 2 and the base stone slab 1, the numerically controlled adhesive layer 5 prevents direct contact between the cloth 2 and the base stone slab 1. Therefore, by bonding the cloth 2 to the base stone slab 1 with the numerically controlled adhesive layer 5 and double-sided tape 6, the fuzz of the cloth 2 is prevented from sticking to the base stone slab 1. By adding a numerically controlled adhesive layer 5 on the back of the cloth 2, whose width matches the second adhesive surface on the base stone slab 1, the adhesive strength between the cloth 2 and the base stone slab 1 is increased. Because the nap on the back of the cloth 2 is a floating nap layer, the adhesive strength is weak after it is attached to the double-sided tape 6 due to the small amount of adhesive. The tensile strength that can withstand the floating nap on the back is very small, so the cloth 2 is prone to rebound after being attached. The rebound causes the cloth 2 on the base stone slab 1 to loosen, affecting the ball's speed. Therefore, by applying a numerically controlled adhesive layer 5 with structural adhesive properties to the back of the cloth 2 and integrating the numerically controlled adhesive layer 5 with the base fabric woven from the warp and weft yarns of the cloth 2, the adhesive strength between the cloth 2 and the double-sided tape 6 is greatly increased, effectively solving the rebound problem of the cloth 2. Furthermore, because the first adhesive surface of the double-sided tape 6 has pressure-sensitive adhesive properties and does not stain the adhered surface after peeling, the problem of the cloth 2 becoming thicker as it is attached to the base stone slab 1 is solved.

[0058] Linear stress relief notches 10 and oblique stress relief notches 11 are provided in the lining 2 at positions corresponding to the side pockets 8 of the base stone slab 1. The linear stress relief notches 10 have a centering function. The overlap of the linear stress relief notches 10 with the center line extending along the width direction of the base stone slab 1 makes it easy to align the lining 2. The linear stress relief notches 10 and oblique stress relief notches 11 divide the lining 2 at each pocket location. The notches allow stress to be relieved in the lining 2 when fastening it to the pocket of the base stone slab 1, allowing the lining 2 to easily fit into the arc-shaped pocket of the base stone slab 1 and firmly adhere to the base stone slab 1 without wrinkles. Compared to the nailing method, the lateral wrinkles in the lining 2 are significantly reduced, unevenness of the lining 2 at the pockets is avoided, the amount of stone slab processing required to process 30 φ8×50 bolt holes on the backside of each billiard table and 30 φ15 counterbores on the frontside is reduced, and the 0.002m used to nail the lining with U-shaped nails is reduced. 3 Based on our factory's production capacity of 30,000 units, this not only saves high-quality cork material every year, but also reduces the workload of installing wooden boards on site.

[0059] The surface of the cloth 2 is provided with a longitudinal attachment detection line 3 extending along the length of the cloth 2 and a transverse attachment detection line 4 extending along the width of the cloth 2. Because the attachment detection lines, parallel or perpendicular to the center line of the cloth 2, are pre-drawn, anyone pulling the cloth 2 can align it with the upper ridge of the edge of the base stone slab 1. This essentially balances the tensile force on the cloth 2, and the warp and weft threads are also straight vertically and horizontally. In this way, the nap orientation of the cloth 2, which has both reverse and normal orientation, is aligned, ensuring stable ball movement and less directional change. This significantly improves the attachment quality of the cloth 2. With the aid of the longitudinal attachment detection line 3 and transverse attachment detection line 4, the cloth 2 is attached to the base stone slab 1 using double-sided tape 6 and a numerically controlled adhesive layer 5, making the attachment of the cloth 2 easy, simple, and quick, and reducing the difficulty of attaching the cloth 2. Lasha 2 can be installed and replaced by anyone, instead of a professional technician, reducing the cost of using and maintaining the billiard table.

[0060] The CNC adhesive layer 5 on the backing 2 and the CNC adhesive layer 7 on the front can both be sprayed automatically using a CNC adhesive applicator. The CNC adhesive applicator can precisely control the width, thickness, and shape of the adhesive, reducing the amount of adhesive used, ensuring adhesive quality, significantly improving work efficiency, and saving labor. When applying structural adhesive manually, it is difficult to precisely control the width and amount of adhesive.

[0061] The flannel 2 used in the above flannel attachment method is cut by a numerically controlled laser cutter. The numerically controlled laser cutter can accurately cut the pocket arc, linear stress relief notch 10, and oblique stress relief notch 11. The combined use of the numerically controlled laser cutter and numerically controlled adhesive applicator allows for efficient assembly line production.

[0062] In addition, in the above-mentioned method for attaching the lining, a front numerically controlled adhesive layer 7 is provided on the front of the lining 2 around the pocket, and the front numerically controlled adhesive layer 7 and the bottom surface of the base stone slab 1 are bonded with double-sided tape 6. The front numerically controlled adhesive layer 7 and the double-sided tape 6 firmly bond the lining 2 in the pocket to the base stone slab 1, preventing the lining 2 from loosening due to rebound caused by tensile force.

[0063] Example 4 This embodiment provides a billiard table to which a flax 2 is attached using any of the flax attachment methods described above. As shown in Figures 4 and 5, the billiard table includes a base slab 1, a flax 2, and double-sided tape 6 for adhering the flax 2 to the base slab 1. The flax 2 is placed on the base slab 1. A numerically controlled adhesive layer 5 is provided around the four periphery of the surface of the flax 2 opposite the surface attached to the base slab 1. Linear stress relief notches 10 and oblique stress relief notches 11 are provided on the flax 2 at positions corresponding to the side pockets 8 of the base slab 1, and oblique stress relief notches 11 are provided on the flax 2 at positions corresponding to the corner pockets 9. The linear stress relief notches 10 have a centering function. The double-sided tape 6 has a first adhesive surface with pressure-sensitive adhesive properties and a second adhesive surface with structural adhesive properties. The first adhesive surface is adhered to the four peripheries of the side and bottom surfaces of the base stone slab 1, and the second adhesive surface is adhered to the numerically controlled adhesive layer 5 and is used to attach the cladding 2 to the base stone slab 1.

[0064] In the billiard table described above, the cloth 2 is attached to the base slab 1 using a numerically controlled adhesive layer 5 and double-sided tape 6, preventing the wool yarn of the cloth 2 from sticking to the base slab 1. The numerically controlled adhesive layer 5 improves the adhesive strength between the cloth 2 and the base slab 1. The structurally adhesive layer 5 is applied to the back of the cloth 2, integrating the layer 5 with the base fabric woven from the warp and weft of the cloth 2. This significantly increases the adhesive strength between the cloth 2 and the double-sided tape 6, effectively resolving the problem of the cloth 2 rebounding. Furthermore, the first adhesive surface of the double-sided tape 6 is pressure-sensitive, meaning that the pressure-sensitive adhesive does not stain the bonded surface after peeling, thereby resolving the problem of the pile of cloth 2 becoming thicker as it is bonded to the base slab 1. The double-sided tape 6 and the numerically controlled adhesive layer 5 allow the cloth 2 to be attached to the base slab 1 easily, simply, and quickly, reducing the difficulty of attaching the cloth 2. Lasha 2 can be installed and replaced by anyone, instead of a professional technician, reducing the cost of using and maintaining the billiard table.

[0065] Furthermore, a circular arc notch that forms a pocket is provided in the base stone slab 1. A front numerically controlled adhesive layer 7 is provided on the front surface of the cladding 2 that surrounds the circular arc notch. As shown in Figure 6, the front numerically controlled adhesive layer 7 and the bottom surface of the base stone slab 1 are adhered together with reinforcing double-sided tape 6.

[0066] A front numerically controlled adhesive layer 7 is applied to the front of the cloth around the pocket, and the front numerically controlled adhesive layer 7 is attached to the bottom of the base stone slab 1 with double-sided tape 6. The front numerically controlled adhesive layer 7 and the double-sided tape 6 prevent the wool of the cloth 2 from sticking to the bottom of the base stone slab 1. The cloth 2 in the pocket is firmly connected to the base stone slab 1, preventing rebound due to the tensile force of the cloth 2 from affecting its usability and aesthetic appearance, and further improving the attachment quality of the cloth 2.

[0067] Example 5 In this embodiment, a cloth 2 for use on a billiard table is provided. As shown in FIG. 5 , the cloth 2 includes a back and a front. A numerically controlled adhesive layer 5 is provided around the four edges of the back. A front numerically controlled adhesive layer 7 is provided at six pocket areas on the front of the cloth 2. As shown in FIGS. 4 and 5 , a marking notch 12 is provided at both ends of the longitudinal centerline of the cloth. The longitudinal centerline is a centerline extending along the length of the cloth 2. The longitudinal centerline divides the cloth 2 into symmetrical left and right portions. The longitudinal centerline is parallel to the long sides of the cloth 2. A linear stress relief notch 10 and a diagonal stress relief notch 11 are provided at both ends of the horizontal centerline. The horizontal centerline is a centerline extending along the width of the cloth 2. The horizontal centerline divides the cloth 2 into symmetrical upper and lower portions. The horizontal centerline is parallel to the short sides of the cloth 2. Oblique stress relief notches 11 are provided at all four corners.

[0068] A numerically controlled adhesive layer 5 is provided around the back of the cloth 2, so that the base slab 1 and the cloth 2 can be connected by the numerically controlled adhesive layer 5 and double-sided tape 6. This allows for quick installation and replacement of the cloth 2 and prevents the fluff of the cloth 2 from sticking to the base slab 1. A front numerically controlled adhesive layer 7 is provided at six pocket locations on the front of the cloth 2. When the back of the cloth 2 is glued to the bottom of the base slab 1, part of the front of the cloth 2 is located at the bottom of the base slab 1, and the front numerically controlled adhesive layer 7 is also located at the bottom of the base slab 1. Part of the double-sided tape 6 is glued to the front numerically controlled adhesive layer 7, and the other part is glued to the bottom of the base slab 1. This connects and reinforces the front of the cloth 2 around the arc-shaped notch to the bottom of the base slab 1, making the connection between the cloth 2 around the pockets and the base slab 1 stronger and more reliable. Marking notches 12 at both ends of the longitudinal centerline facilitate quick positioning of the lining 2 and the base stone slab 1 in the width direction. Linear stress relief notches 10 at both ends of the transverse centerline facilitate quick positioning of the lining 2 and the base stone slab 1 in the length direction. In addition, oblique stress relief notches 11 divide the lining 2 at the pocket area. The notches relieve stress on the lining 2 when fastening it to the pocket of the base stone slab 1, so that the lining 2 can easily fit into the arc-shaped pocket of the base stone slab 1 and firmly adhere to the base stone slab 1 without wrinkles. Stress in the pocket of the lining 2 is reduced. Compared to the nailing method, transverse wrinkles in the lining 2 are significantly reduced, unevenness of the lining 2 at the pocket is avoided, and the 0.002m U-nail used to nail the lining is also reduced. 3 This also reduces the amount of narrow wooden boards used and the workload for installation.

[0069] To facilitate the gluing of the cloth 2, the front surface of the cloth 2 is provided with four vertical attachment detection lines 3 extending along the length of the cloth 2 and parallel to the long edges of the base stone slab 1, and two horizontal attachment detection lines 4 parallel to the bottom edge of the base stone slab 1. The vertical attachment detection lines 3 and the horizontal attachment detection lines 4 may be straight lines or may be formed from a plurality of plotted points or a plurality of line segments spaced apart along a straight line. The vertical attachment detection lines 3 and the horizontal attachment detection lines 4 can be formed using a numerically controlled line drawing machine. That is, the vertical attachment detection lines 3 and the horizontal attachment detection lines 4 are formed on the cloth 2 by drawing straight lines, plotted points, or line segments using a numerically controlled line drawing machine. For ease of distinction, the vertical attachment detection lines 3 and the horizontal attachment detection lines 4 may be a different color from the cloth 2. For example, if the cloth 2 is green, the vertical attachment detection line 3 and the horizontal attachment detection line 4 may be straight lines, plotted dots, line segments or patterns in colors such as white, golden yellow, red, black, etc.

[0070] When attaching the cloth 2, the vertical attachment detection lines 3 and horizontal attachment detection lines 4 on the surface of the cloth 2 after tightening are aligned with the upper ridge lines around the four edges of the base stone slab 2. This indicates that the attachment position of the cloth 2 is as expected. Intuitive detection of the cloth 2 using the vertical attachment detection lines 3 and horizontal attachment detection lines 4 facilitates quick positioning of the cloth 2 on the base stone slab 1, improving the efficiency of attaching the cloth 2.

[0071] The longitudinal attachment detection line 3 and the transverse attachment detection line 4 of the above-mentioned cloth 2 are both formed directly by a numerically controlled wire drawing machine, which has the advantages of accurate drawing position and high reliability. The combination of a numerically controlled wire drawing machine, a numerically controlled laser cutting machine and a numerically controlled adhesive applicator enables an efficient assembly line process for the cloth 2.
