Description

Billiard table, table cloth and installation method thereof Technical Field

[0001] The present invention relates to the technical field of billiards, in particular to a billiard table, a table cloth and an installation method thereof. Background Art

[0002] Billiards has become a popular sport worldwide. A pool table is essential equipment for all types of billiards. A pool table consists of a tabletop, sides, and legs. The tabletop and sides are fixed together and supported on the ground by the legs. The tabletop typically consists of multiple joined stone slabs and a blanket covering the stone slabs. Blanket is a rectangular piece of velvet woven from pure wool or a blend of wool and synthetic fibers. The front side of the blanket must be perfectly flat, with the pile carefully trimmed short and flat, while the back side remains untrimmed. The warp and weft yarns must be of extremely uniform thickness and arranged horizontally and vertically, otherwise the ball's smoothness will be compromised and may cause it to deviate. This is distinct from cloth used for clothing, as competitive tableware is extremely expensive. The frequent rolling and high-speed friction of billiard balls, the constant pushing and rubbing of the player's hands, the constant poking of the cue tip, and the impact of bouncing and falling balls on the blanket all cause the blanket to wear easily. After wear and tear, the nap of table cloth gradually decreases, and microscopic unevenness appears on the warp and weft. At the very least, it affects the smooth rolling of the billiard ball, the ball speed becomes faster, and it is difficult to control. At worst, the ball changes direction, seriously affecting the fun of entertainment and the athletes' competition results.

[0003] Generally, pool tables for households are used less frequently and wear out more slowly. However, in business places such as billiard clubs and bars, they are used more frequently and wear out quickly. Generally, they need to be replaced at least three or four times a year.

[0004] There are two main methods for installing tablecloth on slate countertops: nailing and gluing. Both methods involve evenly laying a rectangular piece of tablecloth slightly larger than the slate countertop. The difference is that the nailing method nails the four sides of the tablecloth to the bottom or sides of narrow wooden strips on the bottom of the slate, while the gluing method avoids installing narrow wooden strips on the bottom of the slate and instead glues the tablecloth directly to the sides of the slate.

[0005] First, the nailing method: Use tacking nails or U-shaped nails to nail the tablecloth to the narrow wooden strips beneath the slate countertop. The narrow wooden strips beneath the slate countertop can be tightened around the sides of the countertop with bolts. Using tacking nails requires a technician with strong arms. First, hold the tablecloth taut with one hand, then twist your wrist to compress it. Then, use your thumb and index finger to receive the tacking nail from your right hand, piercing the nail tip into the tablecloth and wooden strips on the opposite side of the slate countertop to secure the position. With your other hand, use a small hammer to quickly hammer the tacking nail into the wooden strips. This method requires a lot of arm strength, as the technician must rely on this strength to hold the tablecloth taut. Otherwise, loose tablecloth will wrinkle easily when rubbed, affecting the speed of the ball. Furthermore, too loose tablecloth is easily punctured by a club with a missing tip. Without sufficient arm stamina, the technician will install fewer tables per day. Therefore, to improve efficiency and compensate for the lack of arm strength, two technicians are often required to complete the work together. One technician uses both hands to hold the fabric tight while the other technician nails it. U-shaped nails can be driven with a pneumatic or manual nail gun instead of a small hammer, which improves nailing efficiency.

[0006] The DingTalk method has the following disadvantages:

[0007] First, when nailing the six arc-shaped pockets on the slate countertop, especially the two middle pockets, the straight edge of the felt needs to align closely with the arc of the slate side. The length of the straight edge of the felt is significantly different from the length of the arc of the slate. Even applying significant pressure on the straight edge of the felt will not allow it to adhere to the arc of the slate. If nailing is not done properly, the felt will bulge in the middle and not fit snugly against the arc of the pocket. Not only will this bulge affect the ball's placement in the pocket, but when a powerful shot is struck, the ball will bounce back against the arc of the slate after impacting the hole, where it can easily be deflected by the taut, bulging felt. To prevent this bulge, the felt is usually nailed first at the center point of the arc of the middle pocket on one side, then the felt at the arc of the middle pocket on the other side is nailed. At this point, noticeable horizontal wrinkles of considerable height will appear on the flat stone surfaces on either side of the center pocket. These wrinkles can only be eliminated by further tightening the fabric adjacent to the sides. The closer to the arc, the greater the tension, and the greater the deformation of the fabric. Sometimes, tightening the fabric farther from the bottom pocket is necessary to enhance the wrinkle removal effect. In short, relying solely on horizontal tension to eliminate semicircular wrinkles is not ideal. Uneven tension causes unevenness in the fabric surface at the pocket opening. Even the British table used by Ding Junhui in his championship victory was difficult for the World Snooker Federation's British installer to remove wrinkles from the center pocket after installation. Finally, spraying British wool softener and manually smoothing it out improved the wrinkles.

[0008] In addition, wrinkles often appear on the curved surface of the slate surface at the four bottom pockets if you are inexperienced. In addition to affecting the appearance, the higher wrinkles will increase the height of the edge of the pool table, which will also affect the normal use of the pool table. If you want to avoid wrinkles and bulging, you need professional training and a skilled technician to achieve it.

[0009] Second, nailing requires a pneumatic or manual nail gun. While pneumatic nail guns are labor-saving and highly efficient, they require an air source—an air pump. Billiards clubs generally don't have dedicated air pumps, making it inconvenient for professional technicians to carry them around. Furthermore, the noise is disruptive, disrupting business. Clubs typically require professional technicians to work after midnight, requiring extended late-night work, a practice often resisted by technicians. Manual, mechanical nail guns are labor-intensive, prone to wear and tear, have a short lifespan, and require frequent replacement. They also lack power and are unable to penetrate hardwood. Most importantly, long-term use of manual nail guns can lead to wear and tear in the hands of technicians, resulting in irreversible disability.

[0010] Third, to allow for nailing, a ring of wooden planks must be placed around the base of the stone countertop. These planks also have certain requirements: they must be soft, knot-free, and easy to nail, but such planks are generally expensive. Furthermore, up to 36 mounting holes must be pre-cut into the edges of the stone slab, and the holes must have deep chamfers.

[0011] Fourth, when nailing, the fabric is fixed where the nails are placed, while the rest of the fabric, unfixed by the nails, rebounds under the action of elastic force, making the tension uneven. The larger the spacing between the nails, the more obvious the rebound, resulting in a distinct wavy pattern.

[0012] 2. Adhesive method

[0013] The gluing method is more labor-saving. First, manually apply structural adhesive to the sides of the countertop stone slabs and the surfaces of the six pockets. Then, fold the edges of the tablecloth up so that the front of the edge of the tablecloth is in contact with the front of the tablecloth laid on the stone slab, with the back facing up. Manually apply structural adhesive evenly, using a width slightly wider than the side of the stone slab and the arc of the pocket. When the adhesive is dry, follow the following order to paste: 1. First, glue the tablecloth on the middle pocket side of one side to the stone slab; 2. Then, with a little force, glue the tablecloth on the middle pocket side on the opposite side; 3. Glue the tablecloth on one bottom pocket; 4. Then, with force, glue the tablecloth on the opposite side; 5. And so on, glue the other two bottom pockets; 6. Then, smooth all the straight-edge tablecloths except the pockets.

[0014] Disadvantages of gluing method:

[0015] When replacing the tablecloth with new one, the adhesive layer on the old tablecloth where it meets the slate becomes thicker due to the hand-brushed adhesive's viscosity. This, combined with the added nap of the tablecloth during the next replacement, creates an uneven layer of adhesive and nap. This mixture thickens with each replacement, sometimes reaching 1-2 mm. The increased thickness of the slate lengthens the original slate, widening the opening of the bottom pocket and making it harder to score. Furthermore, the unevenness of the thickened layer disrupts the 90° angle of the table's edge, causing it to tilt forward or backward, affecting its elasticity. The unevenness of the tough, mixed layer disrupts the straightness of the edge. In short, gluing compromises the performance of the pool table, especially in a competition-grade pool table. Furthermore, the thickened layer of adhesive and nap, after months of tightening and pressurizing the edge screws, becomes extremely tough, making it difficult to completely remove mechanically and restore the original flatness of the stone edge. Chemical removal is also difficult. Furthermore, the nap on the back of the nap is weak in adhesion and cannot withstand significant tension, so the nap is not as taut as nailing. Untightened nap reduces ball speed. Furthermore, the edge must be screwed on immediately after gluing to hold the nap securely in place to prevent it from loosening.

[0016] The biggest drawback of both nailing and gluing installation methods is that they require professionally trained and skilled technicians. For example, our factory employs over 200 installation technicians each year, traveling across the country. Labor costs are high in Europe and the United States, forcing some clubs to centrally replace the tablecloth and fly professional technicians from Asia, where labor is cheaper, for an annual round-trip installation.

[0017] How to improve the installation method of billiard table cloth, ensure the horizontal and vertical warp and weft of the cloth to the greatest extent, ensure that the direction of the pile is as straight as possible to the bottom pocket, improve the installation quality and speed of the billiard table cloth, reduce the difficulty of installation, and reduce the large number of professional installation technicians, is a difficulty in promoting the development of billiards.

[0018] Summary of the Invention

[0019] In view of this, the present invention provides a billiard table, table cloth and installation method thereof. The table cloth installation method can not only solve the many disadvantages of the nailing method and the gluing method and improve the installation quality, but also has the significant advantage of replacing professional technicians with ordinary people, so that the installation and replacement of table cloth can be completed without professional technicians.

[0020] The present invention adopts the following specific technical solutions:

[0021] The present invention provides a method for installing table cloth for a billiard table. The billiard table includes a tabletop stone slab, table cloth, and double-sided tape for bonding the table cloth to the tabletop stone slab. The double-sided tape has a first bonding surface with pressure-sensitive adhesive properties, a second bonding surface with structural adhesive properties, a first protective film covering the first bonding surface, and a second protective film covering the second bonding surface. The tabletop stone slab has an arc-shaped notch forming a pocket. The table cloth has a back surface bonded to the surface of the tabletop stone slab, a CNC-coated adhesive layer bonded to the side and bottom surfaces of the tabletop stone slab, and a front CNC-coated adhesive layer bonded to the double-sided tape for reinforcement. The installation method comprises the following steps:

[0022] Step 1: Set a CNC glue coating layer around the back of the table cloth, set a straight force unloading cut and a diagonal force unloading cut at the position corresponding to the middle pocket of the table cloth, and set a diagonal force unloading cut at the position corresponding to the bottom pocket of the table cloth. The straight force unloading cut also has a centering function.

[0023] Step 2: Remove the first protective film of the double-sided tape and adhere the first adhesive surface of the double-sided tape to the sides and bottom of the countertop stone slab;

[0024] Step 3: Lay the table cloth on the countertop stone slab with the CNC glue coating layer of the table cloth facing the side of the countertop stone slab;

[0025] Step 4: Tear off the second protective film of the double-sided tape;

[0026] Step 5: Tighten the tablecloth and adhere the CNC glue coating layer of the tablecloth to the second bonding surface of the double-sided tape.

[0027] Furthermore, before step 5, the method further includes:

[0028] On the front of the table cloth, there are four longitudinal installation detection lines arranged along the length direction of the table cloth and two transverse installation detection lines arranged along the width direction of the table cloth;

[0029] When tightening the table cloth, make the longitudinal installation detection line coincide with the upper edge of the long side of the countertop stone slab, and make the transverse installation detection line coincide with the upper edge of the short side of the countertop stone slab.

[0030] Furthermore, the longitudinal installation detection line and the transverse installation detection line are both formed by a CNC line drawing machine.

[0031] Furthermore, the method also includes step six, tearing off the second protective film of the double-sided tape used for reinforcement, and adhering the second adhesive surface to the CNC adhesive layer on the front side of the bag opening and the bottom side of the countertop stone slab, so as to adhere the front side of the table cloth pasted with the arc-shaped notch and the bottom side of the countertop stone slab to the bottom side of the table cloth to prevent the table cloth from loosening at this location.

[0032] Furthermore, the CNC glue coating layer and the front CNC glue coating layer are both formed by automatic spraying using a CNC glue coating machine.

[0033] The present invention also provides a billiard table using the table cloth installation method provided by the above technical solution, the billiard table comprising a tabletop stone slab, table cloth and double-sided tape;

[0034] The table cloth is laid on the table top stone slab, and a CNC glue coating layer is provided around the back surface that is in contact with the table top stone slab. A straight force unloading cut and an oblique force unloading cut are provided at the position of the table cloth corresponding to the middle pocket opening of the table top stone slab, and an oblique force unloading cut is provided at the position of the table cloth corresponding to the bottom pocket opening. The straight force unloading cut has a centering function.

[0035] The double-sided tape has a first bonding surface and a second bonding surface. The first bonding surface is bonded to the sides and bottom of the countertop stone slab, and the second bonding surface is bonded to the CNC glue layer for installing the table cloth on the countertop stone slab.

[0036] Furthermore, the countertop stone slab is provided with an arc-shaped notch forming a pocket, and a front CNC glue layer is provided on the front of the table cloth surrounding the arc-shaped notch; the front CNC glue layer and the bottom surface of the countertop stone slab are bonded and connected by reinforcing double-sided tape.

[0037] In addition, the present invention also provides a table cloth for a billiard table, the table cloth having a back surface and a front surface;

[0038] A numerically controlled glue coating layer is provided around the back side;

[0039] The six pocket openings on the front are provided with a front CNC glue coating layer;

[0040] Marking cuts are provided at both ends of the longitudinal centerline;

[0041] A straight line unloading cutout and an oblique line unloading cutout are provided at both ends of the transverse center line;

[0042] There are oblique force-relieving cuts at all four corners.

[0043] Furthermore, the front side is provided with four longitudinal installation detection lines extending along the length direction of the table cloth and parallel to the long side edges of the table top stone slabs, and two transverse installation detection lines parallel to the bottom side edges of the table top stone slabs.

[0044] Furthermore, the longitudinal installation detection line and the transverse installation detection line are both formed by a straight line, a plurality of marking points or a plurality of line segments.

[0045] Furthermore, the colors of the longitudinal installation detection line and the transverse installation detection line are different from the color of the table cloth.

[0046] Furthermore, the table cloth is cut by a CNC laser cutting machine. Beneficial effects:

[0047] 1. When the table cloth is installed on the countertop stone slab using the table cloth installation method of the present invention, not only is a circle of CNC glue layer provided on the back of the table cloth, but double-sided tape is also adhered around the sides and bottom of the countertop stone slab. The CNC glue layer and the double-sided tape are bonded and connected to fix the table cloth around the sides to the side and bottom of the countertop stone slab. Since the CNC glue layer and the double-sided tape are provided between the table cloth and the countertop stone slab, the CNC glue layer and the double-sided tape can prevent the table cloth from directly contacting the countertop stone slab. Therefore, the CNC glue layer and the double-sided tape are used to adhere the table cloth to the countertop stone slab, which can prevent the fluff of the table cloth from adhering to the countertop stone slab. On the back of the table cloth, Adding a CNC-coated adhesive layer with a width corresponding to the second bonding surface of the countertop stone slab can improve the bonding strength between the tablecloth and the stone slab. Because the nap on the back of the tablecloth is merely a layer of loose hair, when it is bonded to the double-sided tape, the adhesive is insufficient and the bonding is weak. Furthermore, the loose hair on the back can withstand very little tension, causing the tablecloth to easily rebound after being bonded. This rebound causes the stone slab to relax, affecting the ball's speed. Therefore, applying a CNC-coated adhesive layer with structural adhesive properties to the back of the tablecloth, integrating the CNC-coated adhesive layer with the base fabric woven from the warp and weft of the tablecloth, significantly increases the bonding strength between the tablecloth and the double-sided tape, effectively solving the rebound problem. Furthermore, because the first bonding surface of the double-sided tape is pressure-sensitive, the adhesive's characteristic of not contaminating the bonded surface after peeling solves the problem of thickening the nap between the stone slab and the tablecloth.

[0048] 2. In the table cloth installation method of the present invention, a straight unloading cut and an oblique unloading cut are set at the middle pocket of the table cloth corresponding to the table top stone slab, and the straight unloading cut has a centering function. By aligning the straight unloading cut with the center line of the table top stone slab, the position of the table cloth can be easily aligned; the table cloth at each pocket is divided by the set straight unloading cut and oblique unloading cut, and the cut can unload the table cloth when it is tightened to the pocket of the table top stone slab, so that the table cloth and the table top stone slab can be fitted together in the arc-shaped pocket, so that the table cloth and the table top stone slab can be firmly bonded without wrinkles. Compared with the nailing method, the horizontal wrinkles of the table cloth are significantly reduced, and the unevenness of the table cloth at the pocket is avoided. In addition, each table also reduces 30 on the back. Bolt holes and 30 on the front The processing volume of countersunk stone slabs is reduced by 0.02 cubic meters, and the narrow wooden strips for nailing U-shaped nails are reduced by 0.02 cubic meters. Based on our factory's output of 30,000 units, a large amount of high-quality softwood and the workload of on-site installation of wooden strips can be saved every year.

[0049] 3. With the table cloth installation method of the present invention, a longitudinal installation detection line extending along the length direction of the table cloth and a transverse installation detection line extending along the width direction of the table cloth are provided on the surface of the table cloth. Since the installation detection lines parallel to or perpendicular to the center line of the table cloth are drawn in advance, anyone can pull the table cloth with both hands to align it with the upper edge of the edge of the table stone slab, so that the tension on the table cloth is balanced, and the warp and weft are horizontal and vertical. In this way, the hairs of the table cloth with reverse and forward hair directions can be pointed in the same direction, the ball can move smoothly, and it is not easy to change line; therefore, the installation quality of the table cloth can be significantly improved.

[0050] 4. In the table cloth installation method of the present invention, the CNC glue coating layer and the front CNC glue coating layer of the table cloth can be formed by automatic spraying using a CNC glue coating machine. The CNC glue coating machine can accurately control the glue coating width, thickness and shape, which can reduce the amount of glue coating, ensure the quality of glue coating, and greatly improve work efficiency, thereby saving labor; it is difficult to accurately control the glue coating width and amount by manually applying structural glue.

[0051] 5. The table cloth used in the table cloth installation method of the present invention is cut by a CNC laser cloth cutting machine. The CNC laser cloth cutting machine can accurately cut the arc of the bag opening, the straight line unloading incision and the oblique line unloading incision. The CNC laser cloth cutting machine and the CNC glue coating machine can cooperate to form an efficient assembly line operation.

[0052] 6. The table cloth of the present invention is provided with a longitudinal installation detection line for aligning with the long side edge of the table top stone slab and a transverse installation detection line for aligning with the short side edge of the table top stone slab on the front. The longitudinal installation detection line and the transverse installation detection line are directly formed by a CNC marking machine, which has the characteristics of accurate, reliable and efficient marking position. The CNC marking machine can be used in conjunction with a CNC laser cloth cutting machine and a CNC glue coating machine to perform efficient assembly line operations on the table cloth, which is convenient for industrial production and reduces costs.

[0053] 7. The table cloth of the present invention is cut by a CNC laser cloth cutting machine, which can be cut according to the actual shape formed after installation. The table cloth cut by the CNC laser cloth cutting machine has no excess parts that need to be manually removed after installation, reducing the workload of the installer in trimming the excess table cloth after installation.

The tablecloth 2 has a back surface bonded to the surface of the tabletop stone 1, a CNC glue layer 5 bonded to the side and bottom surfaces of the tabletop stone 1, and a front CNC glue layer 7 bonded to the double-sided tape for reinforcement. The installation method includes the following steps:

[0078] Step 1 S10, as shown in the structures of Figures 4, 5 and 6, a CNC glue coating layer 5 is set around the back of the tablecloth 2, a straight force unloading cut 10 and a diagonal force unloading cut 11 are set at the position of the tablecloth 2 corresponding to the middle pocket opening 8, and a diagonal force unloading cut 11 is set at the position of the tablecloth 2 corresponding to the bottom pocket opening 9. In the middle position of the long side of the tablecloth 2, that is, the position where the tablecloth 2 corresponds to the middle pocket opening 8 of the tabletop stone 1, three cuts are set, including one straight force unloading cut 10 and two symmetrically set diagonal force unloading cuts 11. The tablecloth 2 is provided with an diagonal force unloading cut 11 at the position corresponding to the bottom pocket opening 9 of the tabletop stone 1; the straight force unloading cut 10 has a centering function, and the straight force unloading cut 10 is also used to unload force while being used to align with the tabletop stone slab. 1 is aligned with the center line of the table cloth 2 so that the straight unloading cut 10 coincides with the center line of the table top stone slab 1; a front CNC glue coating layer 7 is provided on the front side of the table cloth 2 surrounding the arc-shaped notch, and four longitudinal installation detection lines 3 extending along the length direction of the table cloth 2 and two transverse installation detection lines 4 extending along the width direction of the table cloth 2 are provided on the front side of the table cloth 2; the longitudinal installation detection lines 3 and the transverse installation detection lines 4 can both be straight lines, or can be formed by a plurality of marking points arranged at intervals along the straight line, or can be formed by a plurality of line segments arranged along the straight line; the longitudinal installation detection lines 3 and the transverse installation detection lines 4 can be formed by a CNC line drawing machine, that is, the longitudinal installation detection lines 3 and the transverse installation detection lines 4 can be directly drawn on the table cloth 2 by the CNC line drawing machine. , and for the convenience of distinction, the longitudinal installation detection line 3 and the transverse installation detection line 4 can also use a different color from the table cloth 2. For example, when the table cloth 2 is green, the longitudinal installation detection line 3 and the transverse installation detection line 4 can use straight lines, marking points, line segments or patterns in white, golden, red, black and other colors; the back of the table cloth 2 is in contact with the table stone slab 1, and the front is in contact with the billiard ball for rolling; the CNC glue coating layer 5 is provided on the back of the table cloth 2; the four longitudinal installation detection lines 3 are respectively parallel to the long sides of the table cloth 2, and correspond one-to-one to the ridge lines on the long sides of the table stone slab 1, that is, two longitudinal installation detection lines 3 are provided near each long side of the table cloth 2, and the extension lines of the two longitudinal installation detection lines 3 coincide; the two transverse installation The detection lines 4 are arranged perpendicular to the longitudinal installation detection lines 3 and correspond one-to-one with the short sides of the table cloth 2, that is, a transverse installation detection line 4 is provided near each short side of the table cloth 2. The purpose of providing the transverse installation detection lines 4 and the longitudinal installation detection lines 3 is to ensure that when the table cloth 2 is assembled on the countertop stone slab 1, the transverse installation detection lines 4 coincide with the upper edge lines of the short sides of the countertop stone slab 1, and the longitudinal installation detection lines 3 coincide with the upper edge lines of the long sides of the countertop stone slab 1. In other words, the two transverse installation detection lines 4 and the four longitudinal installation detection lines 3 define the installation position of the table cloth 2. The transverse installation detection lines 4 and the longitudinal installation detection lines 3 can assist in the installation of the table cloth 2 and can also detect the installation quality of the table cloth 2.As shown in the structure of FIG4 , the table stone slab 1 includes two middle pockets 8 and four bottom pockets 9 at the four corners. As shown in the structure of FIG6 , a front CNC glue coating layer 7 is provided on the front of the table cloth 2 around the middle pockets 8 and the bottom pockets 9;

[0079] Step 2 S20: tear off the first protective film of the double-sided tape 6, and adhere the first adhesive surface of the double-sided tape 6 to the sides and bottom of the countertop stone slab 1; after tearing off the first protective film of 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 bottom of the countertop stone slab 1 through the first adhesive surface;

[0080] Step 3 S30: Lay the tablecloth 2 on the countertop stone slab 1, with the CNC-coated adhesive layer 5 of the tablecloth 2 facing one side of the countertop stone slab 1. During the process of laying the tablecloth 2 on the countertop stone slab 1, the length direction of the tablecloth 2 is aligned with the length direction of the countertop stone slab 1, so that the tablecloth 2 covers the top of the countertop stone slab 1 and the sides of the tablecloth 2 cover the sides of the countertop stone slab 1.

[0081] Step 4 S40, tearing 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 tearing off the second protective film, the second adhesive surface of the double-sided tape 6 is exposed;

[0082] Step five S50, tighten the table cloth 2 so that the longitudinal installation detection line 3 coincides with the upper edge of the long side of the countertop stone slab 1, and the transverse installation detection line 4 coincides with the upper edge of the short side of the countertop stone slab 1, and adhere the CNC adhesive layer 5 of the table cloth 2 to the second adhesive surface of the double-sided tape 6; tighten the table cloth 2 covering the countertop stone slab 1, and during the tightening process, the longitudinal installation detection line 3 and the transverse installation detection line 4 can be used as a reference to adjust the position of the table cloth 2 so that the table cloth 2 is symmetrical in the transverse and longitudinal directions, the transverse direction of the table cloth 2 is the extension direction of the short side of the countertop stone slab 1, and the longitudinal direction of the table cloth 2 is the extension direction of the long side of the countertop stone slab 1; and adhere the CNC adhesive layer 5 of the table cloth 2 to the second adhesive surface of the double-sided tape 6, and adhere the table cloth 2 to the bottom surface of the countertop stone slab 1 through the double-sided tape 6 and the CNC adhesive layer 5 of the table cloth 2 to achieve fixed installation of the table cloth 2 on the countertop stone slab 1;

[0083] Step six S60, tear off the second protective film of the double-sided tape 6 used for reinforcement, and adhere the second adhesive surface to the front CNC adhesive layer 7 at the bag opening and the bottom surface of the countertop stone slab 1, so as to adhere the front surface of the tablecloth 2 pasted with the arc-shaped notch and the bottom surface of the countertop stone slab 1 to the bottom surface of the countertop stone slab 1 to prevent the tablecloth 2 at this location from loosening; as shown in the structure of Figure 6, a 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 countertop 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 countertop stone slab 1, further connecting and reinforcing the tablecloth 2 around the arc-shaped notch with the bottom surface of the countertop stone slab 1, so that the connection between the tablecloth 2 around the bag opening and the countertop stone slab 1 is more firm and reliable.

[0084] According to the tablecloth installation method of the above three embodiments, when the tablecloth 2 is installed on the countertop stone slab 1, not only is a circle of CNC glue layer 5 provided on the back of the tablecloth 2, but double-sided tape 6 is also adhered around the sides and bottom of the countertop stone slab 1. The CNC glue layer 5 and the double-sided tape 6 are bonded and connected to fix the tablecloth 2 on the sides and bottom of the countertop stone slab 1. Since the CNC glue layer 5 and the double-sided tape 6 are provided between the tablecloth 2 and the countertop stone slab 1, the CNC glue layer 5 can prevent the tablecloth 2 from directly contacting the countertop stone slab 1. Therefore, the CNC glue layer 5 and the double-sided tape 6 are used to bond the tablecloth 2 to the countertop stone slab 1, which can prevent the fluff of the tablecloth 2 from adhering to the countertop stone slab 1. Adding a CNC-coated adhesive layer 5 on the back of the tablecloth 2, with a width corresponding to the second bonding surface on the countertop stone 1, can improve the bonding strength between the tablecloth 2 and the tablecloth 1. Because the fuzz on the back of the tablecloth 2 is merely a layer of loose hair, when it is bonded to the double-sided tape 6, the adhesive is small and the bond is weak. Furthermore, the loose hair on the back can withstand very little tension, causing the tablecloth 2 to easily rebound after bonding. This rebound causes the tablecloth 2 on the tablecloth 1 to relax, affecting the ball's speed. Therefore, applying a CNC-coated adhesive layer 5 with structural adhesive properties to the back of the tablecloth 2, integrating the CNC-coated adhesive layer 5 with the base fabric woven from the warp and weft of the tablecloth 2, significantly increases the bonding strength between the tablecloth 2 and the double-sided tape 6, effectively solving the rebound problem. Furthermore, because the first bonding surface of the double-sided tape 6 is pressure-sensitive, the characteristic of the pressure-sensitive adhesive that does not stain the bonded surface after peeling solves the problem of thickening fuzz between the tablecloth 1 and the tablecloth 2.

[0085] A straight unloading cutout 10 and an oblique unloading cutout 11 are provided at the position of the middle pocket 8 of the table cloth 2 corresponding to the tabletop stone 1, and the straight unloading cutout 10 has a centering function. By aligning the straight unloading cutout 10 with the center line of the tabletop stone 1 extending along its width direction, the position of the table cloth 2 can be easily aligned. The straight unloading cutout 10 and the oblique unloading cutout 11 are provided to divide the table cloth 2 at each pocket. The cutouts can unload the table cloth 2 when the table cloth 2 is tightened to the pocket of the tabletop stone 1, making it easier for the table cloth 2 to fit the arc-shaped pocket of the tabletop stone 1, thereby firmly bonding the table cloth 2 to the tabletop stone 1 without wrinkles. Compared with the nailing method, the horizontal wrinkles of the table cloth 2 are significantly reduced, the unevenness of the table cloth 2 at the pocket is avoided, and 30 wrinkles on the back of each billiard table are reduced. Bolt holes and front 30 The processing volume of countersunk stone slabs can be reduced by 0.002 cubic meters, and the narrow wooden strips for nailing U-shaped nails can be reduced by 0.002 cubic meters. Based on the output of 30,000 units of our factory, it can not only save high-quality softwood every year, but also save the workload of on-site installation of wooden strips.

[0086] The surface of the table cloth 2 is provided with a longitudinal installation detection line 3 extending along the length direction of the table cloth 2 and a transverse installation detection line 4 extending along the width direction of the table cloth 2. Since the installation detection lines are pre-drawn and parallel or perpendicular to the center line of the table cloth 2, anyone can pull the table cloth 2 to align it with the upper edge of the edge of the table stone slab 1, so that the tension on the table cloth 2 is basically balanced, and the warp and weft are also horizontal and vertical. In this way, the nap of the table cloth 2 with reverse and forward hair direction can be aligned, so that the ball moves smoothly and is not prone to line change; therefore, the installation quality of the table cloth 2 can be significantly improved; with the assistance of the longitudinal installation detection line 3 and the transverse installation detection line 4, the table cloth 2 is bonded to the table stone slab 1 by double-sided tape 6 and the CNC glue layer 5, making the installation of the table cloth 2 easy, simple and quick, reducing the installation difficulty of the table cloth 2, even ordinary people can install and replace the table cloth 2, and can replace professional technicians, thereby also reducing the use cost and maintenance cost of the billiard table.

[0087] The CNC glue coating layer 5 and the front CNC glue coating layer 7 of the table cloth 2 can be formed by automatic spraying using a CNC glue coating machine. The CNC glue coating machine can accurately control the glue coating width, thickness and shape, reduce the amount of glue coating, ensure the quality of glue coating, and greatly improve work efficiency, thereby saving labor; it is difficult to accurately control the glue coating width and amount by manually applying structural glue.

[0088] The table cloth 2 used in the above table cloth installation method is cut by a CNC laser cloth cutting machine. The CNC laser cloth cutting machine can accurately cut the pocket curvature, the straight line unloading cut 10 and the oblique line unloading cut 11. The CNC laser cloth cutting machine and the CNC glue coating machine can cooperate to form an efficient assembly line operation.

[0089] In addition, the above table cloth installation method provides a front CNC glue layer 7 on the front side of the table cloth 2 around the pocket, and is bonded and connected to the front CNC glue layer 7 and the bottom surface of the table top stone slab 1 through double-sided tape 6. The front CNC glue layer 7 and double-sided tape 6 can firmly bond the table cloth 2 at the pocket to the table top stone slab 1 to prevent the table cloth 2 from loosening due to the tensile rebound.

[0090] Example 4

[0091] The present embodiment provides a billiard table in which table cloth 2 is installed using any of the above-mentioned table cloth installation methods, as shown in the structures of Figures 4 and 5. The billiard table includes a tabletop stone 1, table cloth 2, and double-sided tape 6 for bonding the table cloth 2 to the tabletop stone 1; the table cloth 2 is laid on the tabletop stone 1, and a CNC glue layer 5 is provided around the back side where the table cloth 2 and the tabletop stone 1 are in contact, and a linear force-releasing cut 10 and an oblique force-releasing cut 11 are provided at positions corresponding to the middle pocket 8 of the table cloth 2 and the tabletop stone 1, and an oblique force-releasing cut 11 is provided at positions corresponding to the bottom pocket 9 of the table cloth 2. The linear force-releasing cut 10 has a centering function; the double-sided tape 6 has a first bonding surface with pressure-sensitive adhesive properties and a second bonding surface with structural adhesive properties. The first bonding surface is bonded to the side and bottom surfaces of the tabletop stone 1, and the second bonding surface is bonded to the CNC glue layer 5, and is used to mount the table cloth 2 on the tabletop stone 1.

[0092] The billiard table utilizes a CNC-coated adhesive layer 5 and double-sided tape 6 to bond the tablecloth 2 to the tabletop slate 1. This prevents the yarn of the tablecloth 2 from adhering to the tabletop slate 1 and improves the bonding strength between the tablecloth 2 and the tabletop slate 1. A CNC-coated adhesive layer 5 with structural adhesive properties is applied to the back of the tablecloth 2, integrating the CNC-coated adhesive layer 5 with the base fabric woven from the warp and weft of the tablecloth 2. This significantly increases the bonding strength between the tablecloth 2 and the double-sided tape 6, effectively resolving the rebound problem of the tablecloth 2. Furthermore, because the first adhesive surface of the double-sided tape 6 is pressure-sensitive, the adhesive's characteristic of not contaminating the bonded surface after peeling resolves the problem of thickening the nap between the tabletop slate 1 and the tablecloth 2. The table cloth 2 is bonded to the tabletop stone slab 1 by the double-sided adhesive tape 6 and the CNC adhesive coating layer 5, making the installation of the table cloth 2 easy, simple, and quick, and reducing the installation difficulty of the table cloth 2. Even ordinary people can install and replace the table cloth 2, and can replace professional technicians, thereby reducing the use cost and maintenance cost of the billiard table.

[0093] Furthermore, the countertop stone slab 1 is provided with an arc-shaped notch forming a pocket, and a front CNC glue layer 7 is provided on the front side of the table cloth 2 surrounding the arc-shaped notch. As shown in the structure of Figure 6, the front CNC glue layer 7 and the bottom surface of the countertop stone slab 1 are bonded and connected by a double-sided tape 6 for reinforcement.

[0094] Since the front surface of the table cloth around the pocket is coated with a front CNC glue layer 7, and the front CNC glue layer 7 is bonded to the bottom surface of the countertop stone slab 1 through the double-sided tape 6, the front CNC glue layer 7 and the double-sided tape 6 can also prevent the wool of the table cloth 2 from bonding to the bottom surface of the countertop stone slab 1, and can also firmly bond the table cloth 2 in the pocket part to the countertop stone slab 1, preventing the tensile rebound of the table cloth 2 from affecting the performance and appearance of the table cloth 2, thereby further improving the assembly quality of the table cloth 2.

[0095] Example 5

[0096] The present embodiment provides a table cloth 2 for a billiard table, as shown in the structure of Figure 5, the table cloth 2 has a back and a front; a CNC glue layer 5 is provided around the back; a front CNC glue layer 7 is provided at the six pockets on the front of the table cloth 2; as shown in the structures of Figures 4 and 5, marking cuts 12 are provided at both ends of the longitudinal center line of the table cloth, the longitudinal center line is the center line extending along the length direction of the table cloth 2, the longitudinal center line divides the table cloth 2 into symmetrical left and right parts, and the longitudinal center line is arranged parallel to the long side of the table cloth 2; straight force unloading cuts 10 and oblique force unloading cuts 11 are provided at both ends of the transverse center line, the transverse center line is the center line extending along the width direction of the table cloth 2, the transverse center line divides the table cloth 2 into symmetrical upper and lower parts, and the transverse center line is arranged parallel to the short side of the table cloth 2; oblique force unloading cuts 11 are provided at all four corners.

[0097] Since a circle of CNC glue layer 5 is provided on the back of the table cloth 2, the table top stone slab 1 and the table cloth 2 can be bonded together through the CNC glue layer 5 and the double-sided tape 6, which realizes the rapid installation and replacement of the table cloth 2 and can also prevent the fluff of the table cloth 2 from adhering to the table top stone slab 1; a front CNC glue layer 7 is provided at the 6 pocket openings on the front of the table cloth 2. When the back of the table cloth 2 is bonded to the bottom surface of the table top stone slab 1, a part of the front of the table cloth 2 is located at the bottom of the table top stone slab 1, and the front CNC glue layer 7 is also located at the bottom of the table top stone slab 1. A part of the double-sided tape 6 is bonded to the front CNC glue layer 7, and the other part is bonded to the bottom surface of the table top stone slab 1, so that the front of the table cloth 2 on the side around the arc-shaped notch is connected and reinforced with the bottom surface of the table top stone slab 1, so that the connection between the table cloth 2 and the table top stone slab 1 around the pocket opening is more firm and reliable. By the marked incisions 12 at both ends of the longitudinal center line, it is convenient for the table cloth 2 and the table top stone slab 1 to be quickly positioned in the width direction, and by the straight force-relieving incisions 10 set at both ends of the transverse center line, it is convenient for the table cloth 2 and the table top stone slab 1 to be quickly positioned in the length direction; at the same time, the table cloth 2 at the pocket portion is divided by the oblique force-relieving incision 11, and the incision can unload the force of the table cloth 2 when the table cloth 2 is tightened to the pocket portion of the table top stone slab 1, so that the arc-shaped pocket portion of the table cloth 2 and the table top stone slab 1 can be fitted together, so that the table cloth 2 and the table top stone slab 1 can be firmly bonded without wrinkles; reducing the stress of the table cloth 2 at the pocket portion, compared with the nailing method, significantly reducing the transverse wrinkles of the table cloth 2, avoiding the unevenness of the table cloth 2 at the pocket portion, and also reducing the use of 0.002 cubic meters of narrow wooden strips for nailing the table cloth U-shaped nails and the installation workload.

[0098] In order to facilitate the bonding of the table cloth 2, four longitudinal installation detection lines 3 extending along the length direction of the table cloth 2 and parallel to the long side edges of the table top stone slab 1, and two transverse installation detection lines 4 parallel to the bottom side edges of the table top stone slab 1 are provided on the front side of the table cloth 2; the longitudinal installation detection lines 3 and the transverse installation detection lines 4 can both be straight lines, or can be formed by multiple marking points or multiple line segments arranged at intervals along the straight lines; the longitudinal installation detection lines 3 and the transverse installation detection lines 4 can be formed by drawing lines using a CNC line drawing machine, that is, straight lines, marking points, or line segments are drawn on the table cloth 2 by a CNC line drawing machine to form the longitudinal installation detection lines 3 and the transverse installation detection lines 4, and for the sake of convenience in distinction, the longitudinal installation detection lines 3 and the transverse installation detection lines 4 can also use different colors from the table cloth 2, such as: when the table cloth 2 is green, the longitudinal installation detection lines 3 and the transverse installation detection lines 4 can use straight lines, marking points, line segments or patterns in white, golden, red, black and other colors.

[0099] When installing the table cloth 2, the longitudinal installation detection line 3 and the transverse installation detection line 4 on the surface of the tightened table cloth 2 are made to coincide with the upper ridges of the table top stone slab 2. This indicates that the installation position of the table cloth 2 is as expected. The intuitive detection of the table cloth 2 by the longitudinal installation detection line 3 and the transverse installation detection line 4 facilitates the rapid positioning of the table cloth 2 on the table top stone slab 1, thereby improving the installation efficiency of the table cloth 2.

[0100] The longitudinal installation detection line 3 and the transverse installation detection line 4 of the above-mentioned tablecloth 2 are directly formed by a CNC marking machine, which has the characteristics of accurate and reliable marking position. The CNC marking machine can be used in conjunction with a CNC laser cloth cutting machine and a CNC glue coating machine to perform efficient assembly line operations on the tablecloth 2.
