Description

  The present invention relates to a manufacturing system and a manufacturing method for a decorative board used as a door material or a panel material used in furniture, a house, etc., and particularly when the decorative sheet is laminated to the base material, The present invention relates to a system and a method for removing an excess portion of a decorative sheet that protrudes.

  Conventionally, a decorative board using a wooden substrate such as a plywood or a particle board is known as a decorative board used for a door material or a panel material. Such a decorative board is a highly decorative and economical building material by sticking a thin decorative sheet printed with grain or other patterns on the exposed part of the base material, for example, the surface or end face part. It is realized.

  In addition, the magnitude | size of the decorative sheet utilized for such a decorative board is set larger than the size (area where a decorative sheet is stuck) which added the surface and end surface of the base material, and is stuck. This is because when a decorative sheet is applied to a large number of substrates in succession, the size of the decorative sheet that is required to be applied to the surface of the substrate without any gaps due to unevenness or variation in thickness of the substrate surface In order to absorb these variations, it is common to use a decorative sheet that is larger than the base material. Therefore, a trimming process for cutting off the excess excess decorative sheet is necessary.

  By the way, in the said decorative board, as a raw material of the decorative sheet stuck on a base material, a vinyl chloride resin is mentioned, for example. Vinyl chloride resin has many advantages such as easy adjustment of hardness due to the addition of a plasticizer, excellent workability, excellent printability, good embossability, and good machinability. However, it is said that hydrogen chloride gas is generated during incineration, causing acid rain and dioxins. Furthermore, since the vinyl chloride resin has a relatively low softening temperature of about 40 ° C., if it is trimmed immediately after being attached to the substrate surface, it tends to shrink as it cools and hardens. For example, immediately after trimming, even when the entire surface of the substrate K is covered as shown in FIG. 5A, after a certain period of time has passed and the vinyl chloride resin has cooled sufficiently and solidified, As shown in FIG. 5B, the surface of the base material K may be exposed (arrow a). For this reason, it cannot transfer to a trimming process until an adhesive agent and a vinyl chloride resin cool enough, and it is difficult to perform from a sticking process to a trimming process continuously on a series of conveyance lines. Therefore, instead of attaching a decorative sheet having a size larger than that of the base material K and performing trimming, measures such as winding the surplus part around the back surface of the base material K are taken. The design of the back side of the plate is remarkably deteriorated. Moreover, even if another decorative sheet is adhered to the back surface, there is a problem that the method of attaching the decorative sheet for the back surface is also limited by the excess portion of the encased surface decorative sheet. Therefore, in place of vinyl chloride resin, the use of thin paper such as coated paper, which is more environmentally friendly, excellent in cost, and has relatively little expansion / contraction after trimming, has become widespread.

  Here, when thin paper is applied as the decorative sheet, it is necessary to pay attention to the following points in the trimming process. That is, thin paper is a material having water absorption, unlike vinyl chloride resin. Therefore, when an adhesive is applied, the adhesive penetrates to the back of the fiber and becomes soft. When the cutting edge is applied to the thin paper in such a state, the thin paper of the portion hit by the cutting edge escapes and it is difficult to cut out with high accuracy. Therefore, after applying the adhesive, it is necessary to perform a trimming step after drying and recovering the strength of the thin paper after a while. Therefore, conventionally, after the sticking process is completed, the base material is removed from the conveying line, sufficiently dried in another place, and after the adhesive is solidified, the trimming operation is manually performed.

  The above prior art is naturally performed by those skilled in the art, and the applicant is not aware of a document describing the prior art.

  However, according to the above manufacturing method, from the sticking process to the trimming process, in addition to being unable to be performed continuously on a series of transport lines, because a dedicated space for drying is necessary, etc. Productivity was extremely poor. Also, the work of transporting and stacking the base material in such a dedicated space is very laborious and burdens the operator.

  Therefore, in view of the above situation, the present invention is directed to a decorative board manufacturing system and manufacturing method capable of continuously cutting off a surplus portion of a decorative sheet on a series of conveyance lines without bothering human hands. Offering is an issue.

  The decorative board manufacturing system according to the present invention includes: a coating device that applies an aqueous or solvent-based adhesive to the back surface of thin paper on a series of conveying lines, and an end of the thin paper that protrudes from the end surface of the substrate. As described above, an adhesive device that adheres the thin paper to the surface and end face of the base material, and the adhesive applied to the surplus part by cooling the surplus part of the thin paper protruding from the end face of the base material And a trimming device for cutting off the cooled excess portion. "

  Here, the “base material” is not particularly limited, and examples thereof include woody base materials such as particle board, veneer plywood, and MDF (Medium Density Fiberboard). “Cooling” is a temperature at which the solvent in the adhesive is aggregated to promote solidification, and is preferably a temperature lower than room temperature and a temperature that does not cause low-temperature embrittlement of the substrate or thin paper.

  The “water-based or solvent-based adhesive” is not particularly limited as long as it adheres thin paper and a substrate, but for example, a solvent-based adhesive such as a vinyl acetate resin solvent-based adhesive. And aqueous adhesives such as vinyl acetate emulsion adhesives.

  Further, the “cooling and solidifying device” is a device that accelerates the solidification of the solvent by cooling the adhesive applied to the surplus portion at a temperature lower than that at the time of sticking, for example, a blower. “Solidification” means not only the state in which the solvent contained in the adhesive is completely evaporated and solidified, but also the process in which the solvent content in the adhesive is lowered and solidified (so-called dry state) Also included is a state in which the viscosity of the solvent increases and becomes hard. Further, the “trimming device” may be any device as long as it has a blade.

  According to the decorative board manufacturing system of the present invention, the adhesive is evenly applied to the entire back surface of the thin paper by the coating device. And by a sticking process, thin paper is stuck so that it may protrude from the end surface of a base material. By cooling the surplus portion of the thin paper intensively with a cooling and solidifying device, the adhesive applied to the surplus portion can be quickly solidified. As the adhesive is solidified, the fiber component contained in the surplus portion is hardened, and the toughness is generated in the thin paper, and the back is raised. For this reason, even if it presses a blade part, an excess part will not escape, and it can trim easily and accurately. Further, since the adhesive is rapidly solidified by the cooling and solidifying device, a continuous manufacturing process on a series of conveyance lines can be realized.

  Further, according to the decorative board manufacturing system of the present invention, a large-scale and expensive apparatus such as an applicator having a heating tank is used as compared with a case where a hot-melt type (heat-melting type) adhesive is used. Without any problem, the thin paper can be attached to the substrate using a relatively simple configuration. Therefore, the manufacturing system of the decorative board excellent in cost can be provided.

  By the way, in the decorative board manufacturing system of the present invention, “the surplus is after the adhesive is applied to the base material by the applicator and before the surplus portion is cooled by the cooling and solidifying device. It further includes a drying device that evaporates and dries water or a solvent contained in the adhesive applied to the part.

  Here, the “drying device” may be any device that rapidly evaporates the solvent or the like contained in the adhesive, and for example, blows warm air over the surplus portion using a dryer or the like. Alternatively, a drying chamber may be provided on a series of transport lines, and the substrate may be transported and passed through the drying chamber to promote drying of the adhesive.

  According to the decorative board manufacturing system of the present invention, since the surplus portion is dried by the drying device, the solvent and the like contained in the adhesive applied to the surplus portion can be quickly evaporated. Thereby, it can transfer to a trimming process rapidly and can improve the production efficiency of a decorative board further.

  By the way, in the decorative board manufacturing system of the present invention, when the blade part of the trimming device is a straight blade of a type that slides and cuts back and forth, such as a knife or a cutter, chips and surplus parts after excision There is a problem that the adhesive of the adhesive adheres to the blade portion and the sharpness of the blade portion is liable to deteriorate. Further, due to subtle unevenness and inclination existing on the conveying line, the contact point between the blade portion and the base material fluctuates, and there is a possibility that the blade portion contacts not only the surplus portion but also the base material. In this case, the blade portion may bite into the substrate as the substrate is conveyed.

  In view of this problem, the present invention may be "the trimming device has a rotary blade that is disposed in a passage of the base material that is transported by the transport line and cuts off the surplus portion."

  According to the decorative board manufacturing system of the present invention, the trimming device for cutting off the surplus portion has a rotary blade. In the rotary blade, a plurality of blade portions are rotated, brought into contact with a portion to be cut (in this case, an excessive portion), and cut intermittently. At this time, the chips and adhesive adhering to the blade portion are blown away from the blade portion by the rotation of the blade portion, and thus are less likely to be clogged. In addition, since one blade part cuts intermittently, only one blade part does not always contact the part to be cut, so the blade part is not easily heated by frictional heat and prevents the blade part from becoming blunt. , Can last longer. Therefore, the frequency | count of replacing | exchanging a cutter is reduced and production efficiency can be improved.

  In addition, according to the trimming device of the present invention, since the rotating blade is provided, even if the base material and the blade portion may contact each other, the edge portion of the base material is rotated by rotating the shaft that supports the blade portion. The blade portion can be moved to the lower side of the substrate while chamfering the (boundary portion). Therefore, there is little possibility of conveying a base material with the blade biting into the base material. Therefore, the manufacturing system which can manufacture a decorative board more efficiently on a series of conveyance lines can be provided.

  On the other hand, the method for producing a decorative board according to the present invention is described as follows: “A coating process in which an aqueous or solvent-based adhesive is applied to the back surface of a thin paper, and the end of the thin paper protrudes from the end surface of the base material. Adhering step for adhering the thin paper to the surface and the end surface, and a cooling and solidifying step for cooling the surplus portion of the thin paper protruding from the end surface of the base material and solidifying the adhesive applied to the surplus portion. And a trimming step of cutting off the cooled surplus portion are sequentially performed on a series of conveyance lines. "

  Therefore, according to the method for manufacturing a decorative board of the present invention, first, an adhesive is applied to the back surface of the thin paper. And the thin paper with which the adhesive agent was apply | coated is affixed on a base material. Here, in the attaching step, the thin paper is attached to the surface and the end surface of the substrate so that the end portion of the thin paper protrudes from the end surface of the substrate. Thereby, even if the thickness of a base material and the uneven | corrugated state of a surface may change for every base material, thin paper can be reliably affixed on all the base materials.

  Subsequently, the excess portion of the protruding thin paper is intensively cooled by the cooling and solidifying step, and the adhesive applied to the excess portion is quickly solidified. Therefore, with the solidification of the adhesive, the fiber of the paper is hardened, and the toughness is generated in the thin paper.

  Then, the surplus portion is removed by a trimming process. The excess thin paper has toughness due to the cooling and solidifying process, and thus the thin paper is difficult to escape even if the blade is pressed against it, and trimming can be performed relatively easily and accurately. In addition, in the cooling and solidification process, it is not necessary to solidify the adhesive on the entire surface of the thin paper adhered to the base material, it is sufficient to solidify only the adhesive applied to the surplus part, so that the process can be quickly shifted to the trimming process. The production efficiency of the decorative board can be improved.

  By the way, in the manufacturing method of the decorative board of the present invention, “after the application step, a drying step of evaporating and drying water or a solvent contained in the adhesive applied to the surplus portion” is performed. be able to.

  According to the method for producing a decorative board of the present invention, water or a solvent (hereinafter referred to as “solvent” or the like) contained in the adhesive applied to the surplus portion can be quickly evaporated by further performing a drying step. Therefore, a more productive manufacturing method can be provided.

  If the solvent or the like is completely evaporated in the drying step, the solidification reaction of the adhesive proceeds too rapidly, and there is a risk that the surplus portion will wrinkle or shrink. For this reason, it is important not to complete the evaporation in the drying process, but to complete the solidification of the adhesive in the subsequent cooling and solidification process, so that the surplus portion does not bend or curl without fail. The part can be trimmed.

  In this way, by using the decorative plate manufacturing system of the present invention, the process from the sticking process to the trimming process can be performed continuously on a series of transport lines without bothering human hands. It is possible to reduce the burden on the operator for trimming the surplus part. Moreover, since it performs sequentially on a series of conveyance lines, a highly productive manufacturing system can be provided.

  Hereinafter, a decorative board manufacturing system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is an explanatory view schematically showing a manufacturing system of the present invention, FIG. 2 is an explanatory view showing a process of attaching a decorative board, FIG. 3 is a schematic view of a trimming apparatus, and FIG. It is a top view of an apparatus.

  In addition, as shown in FIG. 2A, the decorative board 1 manufactured by the manufacturing system 2 of the present embodiment is applied with the thin paper P on the surface L and the end surface W of the base material K using the adhesive A. Wearing various patterns, colors, and textures. For the base material K, a woody base material such as MDF or particle board is applied. As the thin paper P, a paper-based material such as thin paper on which a pattern or a pattern is printed, coated paper, titanium paper, Japanese paper, or a thin plastic film is used, and preferably has a thickness of 0.05 to 0.4 mm. Applied. In addition, the adhesive A is not particularly limited, but in the present embodiment, a urethane-based adhesive or a vinyl acetate emulsion-type adhesive is used for the paper-based thin paper P, and a plastic film-based adhesive is used. For the thin paper P, a urethane-based adhesive or an ethyl vinyl acetate resin-based adhesive is used.

  As shown in FIG. 1, the manufacturing system 2 of the decorative board 1 of this embodiment manufactures the decorative board 1 on a series of conveyance lines 3, and mainly applies the coating device 4, the sticking device 5, and the drying device. 6, a cooling solidification device 7, a trimming device 8, and the like.

  The conveyance line 3 includes a base 9, a belt conveyor 10, a substrate clamp table 11, a mounting table 12, and the like. The base 9 is a base that forms the base of a series of transfer lines 3, and the total length is set according to the production scale and the site area of the factory. The belt conveyor 10 includes a belt mechanism 13, a pair of belt wheels 14, a driving unit M, and the like. The belt mechanism 13 is a wide endless annular belt, circulates in the base 9 by a pair of belt wheels 14 disposed on both ends of the belt conveyor 10, and conveys the base material K from the right side to the left side of the drawing.

  The base clamp table 11 is used for positioning the base material K in the cooling and solidification process and the trimming process (described later), and the vertical height can be adjusted by a pair of adjusting mechanisms 15. The base clamp table 11 conveys the base material K while holding the left and right end portions (ends on the width direction side from the front side of the drawing) of the base material K in cooperation with the belt mechanism 13. In particular, in the trimming step, the base material K is prevented from moving and being displaced. The mounting table 12 is provided in a state of projecting in a flange shape from the side surface of the base 9 to the outside, so that the trimming device 8 and a polishing machine 35 to be described later can be mounted. .

  The coating device 4 is a device that applies the adhesive A to the back surface of the thin paper P as shown in FIG. As the coating device 4, a known knife coater is applied in this example, but is not limited to this configuration, and a normal roll coater, a reverse roll coater, a gravure coater, a kiss coater using an applicator roll, and the like are known. The coating device can be appropriately selected.

  The sticking apparatus 5 sticks the thin paper P to the end surface W and the surface L of the base material K, as shown in FIG. As a structure, it does not specifically limit and well-known sticking apparatuses, such as a press apparatus, can be illustrated. Note that the length of the thin paper P in the width direction (perpendicular to the conveyance direction of the base material K) is necessary with respect to the width direction of the base material K in order to absorb the size variation of each of the base materials K. Longer than the length (that is, the height of the end face W × 2 + the length in the width direction of the surface L). Therefore, a part of the thin paper P adhered to the end surface W protrudes from the end surface W as a surplus portion Y.

  The drying device 6 (see FIG. 1) is for drying the base material K to which the thin paper P is adhered. In the present embodiment, the drying device 6 has a box-shaped dome shape, and is configured so that the base material K placed on the belt mechanism 13 can pass through the inside. The base material K passes through the inside of the drying device 6, so that hot air is applied to the adhesive A (see FIG. 2B) applied to the surplus portion Y and dried.

  The cooling and solidifying device 7 cools and solidifies the adhesive A (see FIG. 2B) applied to the surplus portion Y of the base material K, and causes the surplus portion Y to become waisted. Examples of the configuration include a blower using a compressor, and a configuration in which cool air of dry ice is blown by a blower. The configuration is configured to blow cool air against the surplus portion Y.

  As shown in FIGS. 3 and 4, the trimming device 8 cuts off the surplus portion Y, and includes a base member 16, a block body 17, a support body 18, a motor 19, a main copying roll 20, an auxiliary copying roll 21, And a rotary blade 22 and the like. The base member 16 is a member that forms the base of the trimming device 8, and is a substantially U-shaped member that is fixed to the mounting table 12. A pair of vertical rails 23 erected in the vertical direction are provided, and the block body 17 can be guided in the vertical direction by the vertical rails 23. An adjustment mechanism 24 is provided between the lower portion of the block body 17 and the support body 16 so that the height of the block body 17 can be adjusted.

  As shown in FIG. 4, a horizontal rail 25 further passes through the block body 17. Both ends of the horizontal rail 25 are fixed with respect to the support 18, and the support 18 can move in the direction of arrow X within the range of the stroke a. The support 18 is disposed on the side surface side of the wall 26, the bottom plate 27 horizontally disposed in the direction of the arrow c from the lower portion of the wall 26, and the wall 26 facing the bottom plate 27. , A member provided with a pair of side plates 28a, 28b extending perpendicularly to the direction of arrow b. The side plates 28 a and 28 b are fixed to the horizontal rail 25, and the motor mounting table 29 is mounted on the bottom plate 27. The motor 19 is mounted on the motor mounting table 29.

  The motor 19 is composed of known driving means such as an electric motor, and rotationally drives the rotary blade 22. The rotary blade 22 is driven to rotate by the motor 19 and is configured to cut off the surplus portion Y. The motor mounting table 29 (see FIG. 3) is provided with an adjusting screw 33 so that the position of the rotary blade 22 can be finely adjusted.

As shown in FIG. 3, the support 18 is further provided with an adjustment mechanism 40 and an urging means 30 for adjusting the positional relationship between the base material K and the rotary blade 22. The adjustment mechanism 40 is attached to the fixed member 41, the moving shaft 42 assembled to the fixed member 41, the slide member 44 pivotally supported on one end side of the moving shaft 42, and the inclination angle of the main copying roll 20. And the main copying roll 20 pivotally supported by the tilt adjusting member 45 so as to be rotatable. The fixing member 41 is fixed to the upper part of the support body 18, and the moving shaft 42 is configured to be movable in the directions of the arrows d and e by turning the adjusting screw 32. The slide member 44 adjusts the tilt angle by sliding the position of the tilt adjusting member 45 in accordance with the amount of movement of the moving shaft 42. The main copying roll 20 is pivotally supported at the end of the inclination adjusting member 45, and the peripheral edge 31 has a disk shape with a taper. The urging means 30 includes a spring, an air cylinder, and the like, and is provided between the side surface 43 of the support 18 and the support 16. The urging means 30 urges the entire support 18 toward the end face W side (arrow e side) of the base material K at a certain constant pressure, for example, a pressure of about 0.5 kg / cm ² . The peripheral edge portion 31 of the main copying roll 20 is configured to be pressed against the end surface W with a predetermined pressure. Therefore, even when the size of the base material K and the transport position change and the position of the end face W moves away from the rotary blade 22 (that is, when the position shifts to the arrow e side), the motor is driven by the biasing force of the biasing means 30. 19 and the rotary blade 22 shift to the base K side. On the other hand, when the position of the base material K is shifted to the arrow d side, the peripheral portion 31 of the main copying roll 20 comes into contact with the end face W, thereby resisting the biasing force of the biasing means 30 and the entire support 18. Is shifted to the arrow d side. By using such a configuration, the positional relationship between the rotary blade 22 and the surplus portion Y can always be kept constant even when the position of the base material K varies. In addition, by turning the adjusting screw 32, the position of the main copying roll 20 that is pivotally supported at the tip of the moving shaft 42 can be moved in the directions of the arrow d and the arrow e. It is a structure which can finely adjust the positional relationship with.

  Further, the support 18 is provided with an auxiliary copying roll 21. The auxiliary copying roll 21 prevents the surplus portion Y of the base material K from adhering to the back surface of the base material K and being left uncut without being able to contact the rotary blade 22. And is arranged so as to be in contact with the lower surface of the base material K. And the surplus part Y is comprised so that it may stand in contact with the rotary blade 22 easily.

  The trimming device 8 further includes a suction device 34 as shown in FIG. The suction machine 34 includes a suction device (not shown), a suction passage 36 having one end connected to the suction device, and a cup (not shown) connected to the other end of the suction passage 36 and surrounding the periphery of the rotary blade 22. In this configuration, dust such as chips generated in a trimming process described later is received by a cup and sucked by a suction device through the suction passage 36.

  The polishing machine 35 (see FIG. 1) is provided with a cloth file (not shown) that is rotatably connected in a state of being pressed against the cut surface of the substrate K, and the base after the surplus portion Y is cut off. It is comprised so that the cut end of the material K may be sharpened and smoothed.

  Then, the manufacturing method of the decorative board 1 of this invention is demonstrated based on FIG. 1 thru | or FIG. The manufacturing method of the decorative board 1 of the present invention can be roughly divided into five steps, namely, “application step”, “sticking step”, “drying step”, “cooling and solidifying step”, and “trimming step”. it can.

  First, in the “application step”, as shown in FIG. 1, the adhesive A is applied to the back surface of the thin paper P (see FIG. 2A). In the “sticking step”, as shown in FIG. 2A, the thin paper P is stuck on the surface L and the end face W of the base material K that has been transported on the belt conveyor 10. Here, since the size of the thin paper P is set larger than the width of the area of the base material K to be pasted, the end portion protrudes from the end portion of the base material K as the surplus portion Y.

  In addition, it is preferable that the sealing agent, such as abrasive powder, is applied to the surface L and the end surface W that are the surfaces to be bonded as pretreatment for bonding. According to this, the space | gap (space | gap between the small pieces of a piece of wood) formed in the surface L and the end surface W is filled with the sealing agent, and the sticking process is ensured. In particular, if a rubber-based paint or resin is applied as a sealing agent, a moisture-proof effect can be obtained in addition to smoothing the surface to be adhered.

  In the “drying step”, as shown in FIG. 1, the adhesive A applied to the surplus portion Y is dried by allowing the substrate K to pass through the drying device 6. Here, it is not preferable to dry the adhesive A too rapidly and completely because it may cause deformation of the surplus portion Y (such as wrinkles and rounding), and the solvent content in the adhesive A is: It is preferable to dry so that it may become 10% or less and 1% or more.

  In the “cooling and solidifying step”, cooling air is blown to the surplus portion Y by the cooling and solidifying device 7. Thereby, the adhesive A applied to the surplus portion Y is quickly solidified. Therefore, the surplus portion Y is not deformed rapidly and the toughness is generated and the waist is raised.

  In the “trimming step”, as shown in FIG. 3, the excessive portion Y of the thin paper P protruding from the end portion of the base material K is cut using the rotary blade 22. The position of the contact point between the rotary blade 22 and the surplus portion Y can be finely adjusted by adjusting the adjusting screws 32 and 33. Further, since the positional relationship between the entire support 18 and the substrate K is kept constant according to the position of the main copying roll 20, the positional relationship between the rotary blade 22 and the substrate K is also kept constant, and is always stable. Maintained contact position. Then, the polishing machine 35 removes the mark remaining at the boundary (fiber components of the thin paper P and the base material K remaining after cutting). That is, an unnecessary part is removed and the whole shape is adjusted. Then, when the operator separates the thin paper P at the boundary portion D (see FIG. 1) of the base material K with a cutter or the like, the decorative sheet 1 for each sheet is taken out.

  As mentioned above, according to the manufacturing system 2 of the decorative board 1 of this example, the surplus part Y solidifies quickly by providing a cooling solidification apparatus. Therefore, the processes from the coating process to the trimming process can be continuously performed on the series of conveyance lines 3. Further, since a series of steps can be sequentially performed on the transfer line 3, the productivity is extremely high.

  Moreover, in this embodiment, by providing a drying device, the cooling and solidifying step can be made efficient, and a production system with higher productivity can be provided. Further, by using the solvent-based adhesive A, it is possible to stick the thin paper P to the base material K using a relatively simple device, and therefore it is possible to provide the decorative board 1 having excellent cost performance.

  Furthermore, according to the present embodiment, by providing the trimming device having the rotary blade, the rotary blade 22 is unlikely to bite into the end surface W, so that it is possible to reduce the possibility that the conveyance is stopped or the rotary blade 22 is broken. In addition, since the rotary blade 22 is rotated and cut intermittently, only the same part of the rotary blade 22 does not always contact the part to be cut (the surplus part Y in this case), so that the sharpness is made longer. An even more efficient and highly productive manufacturing system 2 can be provided.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  In the said embodiment, although the drying apparatus 6 illustrated what sprays warm air with respect to the adhesive agent A apply | coated to the surplus part Y, it is not limited to this, What dry the base material K whole It may be. Further, instead of warm air, it may be one that blows air at normal temperature, and instead of blowing air, the inside of the drying device 6 is kept at a high temperature and the base material K is allowed to pass therethrough. good. In short, any adhesive may be used as long as the adhesive A applied to the surplus portion Y can be quickly dried.

  In the above embodiment, the “drying process” is exemplified as being performed after the “sticking process” and before the “trimming process”. It may be after the “application step” for applying the adhesive A and before the “adhesion step” for attaching the thin paper P to the substrate K. Furthermore, the “drying step” may be performed twice before and after the “sticking step”, and the substrate K is transported on the transport line 3 without applying the drying device 6. The adhesive A may be dried only by natural drying when going. However, as in the present embodiment, at least before the “trimming step”, if the adhesive A is actively dried by the drying device 6, the adhesive of the surplus portion Y is solidified more quickly and reliably. Since trimming can be performed, it is more preferable.

  In the said embodiment, although the operation | work which cuts the thin paper P and takes out one sheet of decorative board 1 illustrated what was performed manually by an operator, it is not limited to this, A well-known automatic cutting machine etc. are used. It is good also as a structure which uses and isolate | separates. Although not shown, as a method for collecting the taken-out decorative board 1, an appropriate method can be selected such as automatic collection by a robot or the like, or loading on a wagon or the like and transported by an operator. is there.
