This application relates to pool tables, and more particularly to a pool table, a table felt thereof, and a method for mounting the table felt.
Billiards has become a popular sport in the world. The pool table is an essential equipment infrastructure for all kinds of billiard games. The pool table includes a playing field, a table edge and multiple legs. The playing field and the table edge are fixedly connected and supported by the multiple legs. The playing field generally consists of multiple spliced slates and table felt laid on the surface of the slates. Table felt is a rectangular piece of velvet made from pure wool or a mixture of wool and chemical fiber. The front surface of the table felt is required to be extremely flat, with the velvet professionally and finely trimmed to be short and flat, while the velvet on the back surface is not required to be trimmed. The warp and weft of the velvet thread are required to be extremely uniform in thickness and arranged horizontally and vertically, otherwise it will affect the stability of the ball movement, causing the ball to change direction. Different from felt for clothing, the table felt for competition is extremely expensive. Due to the frequent rolling and high-speed friction of billiard balls, the constant pushing and rubbing by the hands of a player, the constant poking by the leather tip of the cue, or the bumping of the ball against the table felt when it bounces and falls, the table felt is susceptible to wear. The worn table felt exhibits a gradual decreased velvet, and the warp and weft lines appear microscopic unevenness, which might affect the smooth rolling of the billiard ball, cause the billiard ball to speed up and become difficult to control, or even lead to ball turn, seriously affecting the playability of billiards games and the performance of a player.
Generally, pool tables for households are used less frequently and wear out more slowly. However, in business places such as billiard clubs and bars, pool tables are used more frequently and wear out quickly, which need to be replaced at least three or four times a year.
In the prior art, the methods for laying table felt on a slate include a nailing method and a gluing method. Both of the two methods involve evenly laying a rectangular table felt slightly larger than the slate on the slate. The difference is that the nailing method is to nail the four sides of the table delt to the bottom or side surface of the narrow wooden strips on the bottom surface of the slate, while the gluing method does not require the mounting of the narrow wooden strips on the bottom surface of the slate, and is to directly glue the table felt to the side surface of the slate.
The nailing method is performed as follows. The table felt is nailed to the narrow wooden strips at the back of the slate via hardware nails or U-shaped nails. The narrow wooden strips can be fixed around the back surface of the slate via bolts. Nailing the table slate with hardware nails requires a technician with strong arms. First, the table felt is stretched with one hand and pressed by turning the wrist. Then, the hardware nail is positioned by using the thumb and index finger, so that the nail tip penetrates the table slate and the wooden strip on the back surface of the slate for fixation. The nail is quickly nailed into the wooden strips using a small hammer with the other hand. This method requires high arm strength, which is needed to stretch the table felt. Otherwise, the unstretched table felt may easily wrinkle when rubbed by hand, thereby affecting the speed of the ball. In addition, the table felt that is too loose is prone to be punctured by a cue with a missing tip. A technician without sufficient arm strength can assemble relatively few pool tables per day. Therefore, in order to improve efficiency and make up for the lack of arm strength, it is often necessary for two technicians to work together, one to stretch the table felt with both hands, and the other for nailing. U-shaped nails can be nailed with pneumatic nail guns or manual nail guns instead of small hammers, which improves nailing efficiency.
The nailing method has the following disadvantages.
Firstly, when nailing at the six arc-shaped pockets of the slate, especially the two middle pockets, the straight edge of the table felt here needs to be closely attached to the arc at the edge of the slate. However, the length of the straight edge is obviously not equal to the length of the arc of the slate. The straight edge of the table felt fails to be closely attached to the arc of the slate even when a lot of pressure is exerted. Poor nailing may cause the table felt to appear in central bulging and fail to closely attached to the arc-shaped pocket. The bulging will affect the ball falling into the pocket. When the ball is hit hard, it will bounce back to the arc of the slate after hitting the hole, where is prone to be bounced out by the tight and bulging table felt. In order to prevent bulging, the table felt is commonly nailed at the center point of the arc of the middle pocket on one side, and then nailed at the center point of the arc of the middle pocket on the other side. At this time, obvious horizontal wrinkles with a certain height will appear on the slate plane on both sides of the middle pocket. These wrinkles can only be eliminated by further stretching the table felt near the side. The closer to the arc, the greater the tension, the greater the deformation of the table felt. Sometimes it is necessary to stretch the table felt at the bottom pocket farther away to enhance the wrinkle removal effect. In summary, the effect of eliminating wrinkles by horizontal tension is not very ideal. The uneven tension leads to uneven table felt at the pocket opening. Even for the British table that Ding Junhui used when he won the championship, the British technician of the World Snooker Federation was a little overwhelmed by the wrinkles at the middle pocket after mounting. Finally, the table felt was sprayed with British wool softener and then smoothed with hands to improve the flatness.
In addition, lack of experience may often cause wrinkles to appear on the arc of the slate surface at four bottom pockets. In addition to affecting the appearance, high wrinkles may lead to an increased height of the rail, which will also affect the normal use of the pool table. Only professionally trained and skilled technicians can achieve no wrinkles and no bulges.
Secondly, the method of nailing U-shaped nails requires a pneumatic or manual nail gun. The pneumatic nail gun, while labor-saving and highly efficient, require an air source, i.e., an air pump. Generally, billiard clubs are not equipped with special air pumps. It is also inconvenient for professional technicians to carry air pumps. Moreover, the air pump will produce noise that affects business. Generally, the professional technicians are required to work after midnight in clubs, which causes long-term staying up late and is resisted. Manual mechanical nail guns are laborious and prone to wear, which not only have a short service life and need to be replaced frequently, but they also have low power and fail to nail hard wood. Most importantly, long-term use of manual nail guns will cause the technicians' hands to be damaged due to overwork, resulting in irreversible disability.
Thirdly, wooden boards must be arranged around the bottom of the slate for nailing. These wooden boards also need to meet certain requirements, including soft texture, no knots and easy to nail. Such wooden boards generally lead to high costs. In addition, 36 mounting holes need to be pre-processed on the edge of the slate, which need to be set with deeper chamfers.
Fourthly, when nailing, the table felt at the nailing position is fixed, and the other parts not fixed by the nails rebound under the action of elastic force, resulting in uneven stretched elastic force. The larger the spacing between the nails, the more obvious the rebound, resulting in obvious wavy shapes.
The gluing method is more labor-saving. First, structural glue is manually applied to the sides of the slate and the surfaces of the six pocket openings. Then, the edges of the four sides of the table felt are folded and turned up, so that the front surface of the table felt contacts the front surface of the table felt laid on the slate with the back surface facing up. The structural glue is manually and evenly applied with a width slightly wider than the side of the slate and the arc of the pocket opening. After the glue is dry, the gluing is performed in the following sequence. 1. The middle pocket of one side is bonded to the slate. 2. The middle pocket of the other side is bonded to the slate. 3. The bottom pocket of one side is bonded to the slate. 4. The bottom pocket of the other side is bonded to the slate. 5. Other two bottom pockets are bonded to the slate in the same way. 6. All the straight-edges of the table felt are flattened except the pocket opening.
The gluing method has the following disadvantages.
When replacing a new table felt, the adhesive layer on the bonding surface between the old table felt and the slate is thick due to the viscosity of the hand-brushed adhesive. Moreover, each time the table felt is replaced, a layer of velvet is detached. After several times, a mixture layer of structural adhesive and table felt velvet with uneven thickness will be formed. As the number of replacements increases, the mixture layer will become thicker and thicker, sometimes up to 1-2 mm. This leads to an increase in the thickness of both sides of the slate, making the original slate longer and the bottom pocket larger, changing the difficulty of scoring a goal. Moreover, the uneven thickened layer formed by the mixture destroys the 90° angle of the mounting surface of the rail, which is either tilted forward or backward, affecting the elasticity of the rail. The unevenness of the tough mixed layer destroys the straightness of the rail. In summary, the gluing method destroys the performance of the pool table, especially the competition-type pool table. Moreover, the thickened layer formed by the mixture of the adhesive and the velvet has extremely high toughness under the stretching and pressure of the screws at the rail for several months, which is difficult to be completely removed mechanically to restore the flatness of the original slate edge, and is also difficult to be removed chemically. In addition, the table felt cannot withstand a large tensile force due to the due to the weak adhesion of the velvet on its back, and is not as tight as the nailing method. The unstretched table felt affects the ball running speed. After bonding, the rail must be screwed on immediately to tightly press the table felt, thereby preventing the table felt from loosening.
The most serious problem of the two mounting methods is that they must be performed by professionally trained and skilled technicians. Due to the high labor costs in Europe and the United States, some clubs can only centralize the replacement of the table felt, and invite professional technicians from Asia, where has low labor costs, to fly back and forth for mounting once a year.
How to improve the mounting method of the table felt to maximize the horizontal and vertical alignment of the warp and weft lines of the table felt and ensure that the velvet is directed to the bottom pocket as straight as possible, thereby improving the installation quality and speed of the table felt, reducing the mounting difficulty and the demand for a large number of professional technicians, has become a difficulty in promoting the development of billiards.
An object of the disclosure is to provide a pool table, a table felt thereof and a method for mounting the table felt, which can not only solve the deficiencies of the nailing method and the gluing method to improve the mounting quality, but also contribute to replacing professional technicians with ordinary person, so that the mounting and replacement of the table felt can be completed without professional technicians.

In the process of stretching the table felt 2, the position of the table felt 2 can be adjusted with reference to the four longitudinal detection lines 3 and the two transverse detection lines 4, such that the table felt 2 is symmetrically arranged in the transverse and longitudinal directions. The transverse direction of the table felt 2 is an extension direction of the second edge of the slate 1, and the longitudinal direction of the table felt 2 is an extension direction of the first edge of the slate 1. The table felt 2 is bonded to the bottom surface of the slate 1 by means of the first double-sided tape 6 and the first CNC glue coating layer 5, so that the table felt 2 is fixedly mounted to the slate 1.
(S60) A protective film of the second double-sided tape 6 is teared off, and an adhesive surface of the second double-sided tape 6 is bonded to positions of the second CNC glue coating layer 7 where the side pocket opening and the corner pocket opening are located and the bottom surface of the slate 1, such that the top surface of the table felt 2 is bonded to the bottom surface of the slate 1 at the first arc-shaped notch and the second arc-shaped notch to prevent the table felt 2 from loosening. As shown in
For the method of the present disclosure, when mounting the table felt 2 to the slate 1, the first CNC glue coating layer 5 is provided around the bottom surface of the table felt 2, and the first double-sided tape 6 is bonded around the side surface and bottom surface of the slate 1. Edges of the table felt 2 are fixedly mounted to the side surface and bottom surface of the slate 1 be means of the adhesive connection between the first CNC glue coating layer 5 and the first double-sided tape 6. The table felt 2 is prevented from directly contacting the slate 1 due to the arrangement of the first CNC glue coating layer 5 and the first double-sided tape 6 between the table felt 2 and the slate 1. In this way, the velvet of the table felt 2 is prevented from bonding to the slate 1. The first CNC glue coating layer 5 with a width corresponding to that of the second adhesive surface is provided on the bottom surface of the table felt 2, which can improve the bonding strength between the table felt 2 and the slate 1. Since the velvet on the bottom surface of the table felt 2 is just a layer of floating fluff, when the bottom surface is bonded with the first double-sided tape 6, the table felt 2 is prone to rebound after bonding due to the small amount of glue, the weak bonding, and the small tensile force it can withstand. The rebound of the table felt 2 leads to relaxation, which affects the speed of the ball. Therefore, the first CNC glue coating layer 5 with structural adhesive properties is applied to the bottom surface of the table felt 2, so that the first CNC glue coating layer 5 is integrated with the base fabric woven by the warp and weft lines of the table felt 2, which can significantly increase the bonding strength between the table felt 2 and the first double-sided tape 6, thereby effectively preventing the table felt 2 from rebound. Moreover, the first adhesive surface is coated with the pressure-sensitive adhesive, so that the characteristic of the pressure-sensitive adhesive that it does not contaminate the bonded surface after peeling is utilized to solve the problem of the increasingly thick mixture layer of adhesive and the velvet on the slate 1.
The straight notch 10 and the first oblique notch 11 are set at the position on the table felt 2 where the side pocket opening 8 is located, and the straight notch 10 is configured for alignment. In this way, the straight notch 10 is coincident with the center line of the slate 1, which facilitates the alignment of the position of the table felt 2. The table felt 2 at each pocket opening is cut by setting the straight notch 10 and the oblique notch 11, such that the table felt 2 can be unloaded through the notches when the table felt 2 is stretched on the pocket openings of the slate. This facilitates the attachment of the table felt 2 to the arc-shaped notch of the slate 1, so that the table felt 2 can be firmly bonded to the slate 1 without wrinkles. Compared with the nailing method, the horizontal wrinkles of the table felt 2 are significantly reduced, and the unevenness of the table felt 2 at the pocket openings is avoided. In addition, the processing of 30 φ8×50 bolt holes on the bottom surface of the slate 1 and 30 φ15 countersinks on the top surface of the slate and 0.02 cubic meters of narrow wooden strips for nailing U-shaped nails can be eliminated. In this way, a large amount of high-quality softwood and the workload of on-site mounting of wooden strips can be saved every year.
The top surface of the table felt 2 is provided with four longitudinal detection lines 3 extending along the length direction of the table felt 2 and two transverse detection lines 4 extending along the width direction of the table felt 2. Since the four longitudinal detection lines 3 and the two transverse detection lines 4 have been drawn in advance, anyone can pull the table felt 2 with both hands for aligning with the edges of the slate 1, so that the tension on the table felt 2 is balanced and the warp and weft lines are respectively horizontal and vertical. In this way, the velvet of the table felt 2 can be directed in the same direction, making the ball move smoothly and not prone to change line. Therefore, this method can significantly improve the mounting quality of the table felt 2. With the assistance of the four longitudinal detection lines 3 and the two transverse detection lines 4, the table felt 2 is bonded to the slate 1 through the first double-sided tape 6 and the first CNC glue coating layer 5, resulting in easy, simple and quick mounting of the table felt 2. This reduces the difficulty of mounting the table felt 2, so that even ordinary person enables to mount and replace the table felt 2 instead of a professional technician, thereby reducing the using cost and maintenance cost of the pool table.
The first CNC glue coating layer 5 and the second CNC glue coating layer 7 can be formed by automatic spraying using a CNC glue coating machine. The CNC glue coating machine can accurately control the width, thickness and shape of the glue coating, which can reduce the amount of glue coating, ensure the quality of glue coating, and significantly improve work efficiency, thereby saving labor effort. It is difficult to accurately control the width and amount of glue coating by manually coating structural adhesive.
In the method of the present disclosure, the table felt 2 is formed by cutting using a CNC laser fabric cutting machine. The CNC laser fabric cutting machine can accurately form the arc-shaped notches, the straight notches 10 and the oblique notches 11 by cutting. The cooperation of the CNC laser fabric cutting machine and the CNC glue coating machine can form an efficient assembly line operation.
In addition, the second CNC glue coating layer 7 is arranged at the areas on the top surface of the table felt 2 around the side pocket openings 8 and the corner pocket openings 9, and is adhesively connected to the bottom surface of the slate 1 through the second double-sided tape 6. In this way, the table felt 2 at the portions corresponding to the pocket openings can be firmly bonded to the slate 1 to prevent the table felt 2 from loosening due to the rebound of the tension.
A pool table adopting the above method is provided. As shown in
For the pool table of the present disclosure, the table felt 2 is bonded to the slate 1 by means of the first CNC glue coating layer 5 and the first double-sided tape 6, which can prevent the velvet of the table felt 2 from bonding to the slate 1. The first CNC glue coating layer 5 can improve the bonding strength between the table felt 2 and the slate 1. The first CNC glue coating layer 5 with structural adhesive properties is provided on the bottom surface of the table felt 2, so that the first CNC glue coating layer 5 is integrated with the base fabric woven by the warp and weft lines of the table felt 2, which can significantly increase the bonding strength between the table felt 2 and the first double-sided tape 6, thereby effectively preventing the table felt 2 from rebound. Moreover, the first adhesive surface is coated with the pressure-sensitive adhesive, so that the characteristic of the pressure-sensitive adhesive that it does not contaminate the bonded surface after peeling is utilized to solve the problem of the increasingly thick mixture layer of adhesive and the velvet on the slate 1. The table felt 2 is bonded to the slate 1 through the first double-sided tape 6 and the first CNC glue coating layer 5, resulting in easy, simple and quick mounting of the table felt 2. This reduces the difficulty of mounting the table felt 2, so that even ordinary person enables to mount and replace the table felt 2 instead of a professional technician, thereby reducing the using cost and maintenance cost of the pool table.
In an embodiment, the slate 1 is provided with the first arc-shaped notch for forming the side pocket opening and the second arc-shaped notch for forming the corner pocket opening. Areas on a top surface of the table felt 2 around the first arc-shaped notch and the second arc-shaped notch are each provided with the second CNC glue coating layer 7. As shown in
The areas on the top surface of the table felt 2 around the first arc-shaped notch and the second arc-shaped notch are each provided with the second CNC glue coating layer 7, and the second CNC glue coating layer 7 is bonded to the bottom surface of the slate 1 through the second double-sided tape 6, which can also prevent the velvet of the table felt 2 from bonding to the bottom surface of the slate 1. In addition, by virtue of such arrangement, the table felt 2 at the portions corresponding to the pocket openings can be firmly bonded to the slate 1 to prevent the table felt 2 from rebounding due to tension to affect the performance and appearance of the table felt 2, thereby improving the assembly quality of the table felt 2.
A table felt 2 of a pool table is provided herein. As shown in
Since the first CNC glue coating layer 5 is provided around the bottom surface, the table felt 2 can be adhesively connected to the slate 1 through the first CNC glue coating layer 5 and the first double-sided tape 6, thereby achieving the rapid mounting and replacement of the table felt 2, and preventing the velvet of the table felt 2 from bonding to the slate 1. Portions of the top surface corresponding to six pocket openings are each provided with the second CNC glue coating layer 7. When the bottom surface of the table felt 2 is bonded to the bottom surface of the slate 1, the second CNC glue coating layer 7, as well as a part of the top surface of the table felt 2, is located at the bottom surface of the slate 1. A part of the second double-sided tape 6 is bonded to the second CNC glue coating layer 7, and the other part of the second double-sided tape 6 is bonded to the bottom surface of the slate 1, so as to connect and reinforce the top surface of the table felt 2 around the arc-shaped notches with the bottom surface of the slate 1, resulting in a more firm and reliable connection between the table felt 2 and the slate 1. The marking cuts 12 at both ends of the longitudinal center line facilitate the rapid positioning of the table felt 2 and the slate 1 in the width direction. The straight notches 10 provided at both ends of the transverse center line facilitate the rapid positioning of the table felt 2 and the slate 1 in the length direction. Moreover, the portions of the table felt 2 at each pocket opening is cut by setting the straight notches 10 and the oblique notches 11, such that the table felt 2 can be unloaded through the notches when the table felt 2 is stretched on the pocket openings of the slate. This facilitates the attachment of the table felt 2 to the arc-shaped notch of the slate 1, so that the table felt 2 can be firmly bonded to the slate 1 without wrinkles, thereby reducing the stress applied to the portions of the table felt 2 at each pocket opening. Compared with the nailing method, the horizontal wrinkles of the table felt 2 are significantly reduced, and the unevenness of the table felt 2 at the pocket openings is avoided. In addition, the use and workload of 0.02 cubic meters of narrow wooden strips for nailing U-shaped nails can be eliminated.
In order to facilitate the bonding of the table felt 2, the top surface is provided with four longitudinal detection lines 3 extending along a length direction of the table felt 2 and parallel to a first edge of a slate 1, and is provided with two transverse detection lines 4 parallel to a second edge of the slate 1. The first edge of the slate 1 is longer than the second edge of the slate 1. The four longitudinal detection lines 3 and the two transverse detection lines 4 are each formed by a straight line, a plurality of marking points or a plurality of line segments using a CNC line drawing machine, that is, the straight line, the plurality of marking points or the plurality of line segments are drawn on the table felt 2 by the CNC line drawing machine to form the four longitudinal detection lines 3 and the two transverse detection lines 4. For the convenience of distinction, the four longitudinal detection lines 3 and the two transverse detection lines 4 can be different from the table felt 2 in color. For example, in a case where the table felt 2 is green, the four longitudinal detection lines 3 and the two transverse detection lines 4 can be straight lines, marking points, line segments or patterns in white, golden, red or black.
When mounting the table felt 2, the four longitudinal detection lines 3 and the two transverse detection lines 4 on the top surface of the stretched table felt 2 are coincident with edges of the side surface of the slate 1, which indicates that the table felt 2 is located at the expected mounting position. The table felt 2 can be visually detected through the four longitudinal detection lines 3 and the two transverse detection lines 4, which facilitates the rapid positioning of the table felt 2 on the slate 1, thereby improving the table felt mounting efficiency.
The four longitudinal detection lines 3 and the two transverse detection lines 4 are directly formed by means of a CNC line drawing machine, which is accurate in line positioning, reliable and efficient. The cooperation of the CNC laser fabric cutting machine and the CNC line drawing machine facilitates efficient assembly line operation on the table felt, thereby facilitating industrial production and cost reduction.
In summary, the embodiments described above are merely illustrative of the present application, and are not intended to limit the scope of the present application. It should be understood that various modifications, replacements and improvements made by those of ordinary skill in the art without departing from the spirit of this application shall fall within the scope of the disclosure defined by the appended claims.
