Then, the transportation is facilitated compared with transporting the large functional roll 3. Furthermore, in the event that some of the module functional rolls X of the functional roll 3 have a failure, that module functional roll X can be replaced at the customer's place.
- the nonwoven fabric sheets 7 and 8 are used to produce a module functional roll X. It is possible to use only the nonwoven fabric sheets 7 to produce a module functional roll X.

FIG. 1 shows afunctional roll 3 according to this embodiment. Thefunctional roll 3 comprises a shaft body 300 (rotation shaft), aroll body 303,flanges 302, andbearings 301. Theshaft body 300 is cylindrical and hollow and has pores on the outer peripheral surface. Theshaft body 300 has grooves extending in the axial direction on the outer peripheral surface (not-shown). Theroll body 303 is formed around theshaft body 300. Theroll body 303 is in the form of a column having a bore in the center through which theshaft body 300 runs. Theflanges 302 andbearings 301 are formed at both ends of theshaft body 300, respectively. - The
roll body 303 of thefunctional roll 3 is formed by stacking multiple module functional rolls X.FIGS. 2A to 2C show a module functional roll X. The module functional roll X is in the form of a column having abore 300a in the center. The module functional roll X is formed by stacking multiplenonwoven fabric sheets 7 andnonwoven fabric sheets 8. The module functional roll X is united and cannot be disassembled unless some special treatment is done. Both thenonwoven fabric sheet 7 and thenonwoven fabric sheet 8 are in the form of a thin disc having a hole in the center. -
FIGS. 3A and3B show thenonwoven fabric sheet 7.FIG. 3A showsmultiple fabric sheets 7 stacked.FIG. 3B shows a piece of anonwoven fabric sheet 7. Thenonwoven fabric sheet 7 has a circular outer peripheral surface 6 and a through-hole 5 (opening) in the center. The outer periphery of the hole 5 (the inner peripheral surface of the nonwoven fabric sheet 7) is slightly irregular. Theshaft body 300 is inserted in thehole 5. Thenonwoven fabric sheet 7 hasmultiple notches 7a on the inner peripheral surface at given intervals. -
FIGS. 4A and 4B show thenonwoven fabric sheet 8.FIG. 4A showsmultiple fabric sheets 8 stacked.FIG. 4B shows a piece of anonwoven fabric sheet 8. Thenonwoven fabric sheet 8 has a circular outerperipheral surface 10 and a through-hole 9 (opening) in the center. The outer periphery of the hole 9 (the inner peripheral surface of the nonwoven fabric sheet 8) is slightly irregular. Theshaft body 300 is inserted in thehole 9. - As shown in
FIGS. 2A to 2C , the module functional roll X is formed by stacking multiplenonwoven fabric sheets 7 and onenonwoven fabric sheet 8 alternately. Thehole 5 of thenonwoven fabric sheets 7 and thehole 9 of thenonwoven fabric sheet 8 are stacked to form thebore 300a of the module functional roll X. - The center bore 300a of the module functional roll X has a diameter nearly equal to the diameter of the outer circumferential circle of the
shaft body 300 and theshaft body 300 is inserted in the center bore 300a of the module functional roll X. The protrusions of the above-describednonwoven fabric sheets shaft body 300 to prevent thenonwoven fabric sheets - After the
shaft body 300 is inserted in the center bore 300a of the module functional roll X, thenotches 7a of thenonwoven fabric sheets 7 face theshaft body 300 and create semicircular spaces between theshaft body 300 and module functional roll X. - On the other hand, the
nonwoven fabric sheet 8 has no notch. After theshaft body 300 is inserted in the center bore 300a of the module functional roll X, almost the entire inner periphery of thenonwoven fabric sheet 8 reaches the outer periphery of theshaft body 300. Stacked alternately with multiplenonwoven fabric sheets 7 havingnotches 7a, thenonwoven fabric sheet 8 seems to havemultiple extensions 8a reaching the outer periphery of theshaft body 300 around thebore 300a (the inter periphery of the nonwoven fabric sheet 8) at given intervals. Theextensions 8a partition a semicircular column space formed by anotch 7a and theshaft body 300 at given intervals in the axial direction. Multiplenonwoven fabric sheets 7 and onenonwoven fabric sheet 8 are stacked alternately so that thenonwoven fabric sheet 8 is situated at given intervals along a mountingshaft 2. - Both the
nonwoven fabric sheet 7 and thenonwoven fabric sheet 8 are made of porous materials. The nonwoven fabric sheet 8 (the second nonwoven fabric sheet) has a lower density than the nonwoven fabric sheet 7 (the first nonwoven fabric sheet).FIG. 5 shows a nonwovenfabric sheet material 1 used as the material of thenonwoven fabric sheet 7 ornonwoven fabric sheet 8. Membrane-like bridgingelastic bodies 100 are present on thesuperimposed surfaces fabric sheet material 1.FIG. 6A is an enlarged view of the superimposedsurface 1a inFIG. 5 .FIG. 6B is an enlarged cross-sectional view of a nonwoven fabric sheet material. As shown inFIGS. 6A and6B , the bridgingelastic bodies 100 are present on thesuperimposed surfaces fabric sheet material 1. - The method of producing the above-described
functional roll 3 will be described hereafter. First, the method of producing the nonwovenfabric sheet material 1 used as the material of thenonwoven fabric sheet 7 andnonwoven fabric sheet 8 will be described.FIGS. 7A and 7B show an exemplary method of producing the nonwovenfabric sheet material 1. First, as shown inFIG. 7A , a strip of nonwoven fabric material B is stacked/superimposed in a pleat-like fashion on a transfer conveyer A so as to create a wide nonwoven fabric C. Then, as shown inFIG. 7B , the nonwoven fabric C is immersed in a bridging elastic material reservoir D so that a bridging elastic material E is attached to the entire nonwoven fabric C. With the bridging elastic material E (the bridging elastic bodies 100) attached to the front and back sides of the nonwoven fabric C, a larger amount of the bridging elastic material E is attached to the front and back sides (thesuperimposed surfaces fabric sheet material 1. The completed nonwovenfabric sheet material 1 is used to form thenonwoven fabric sheet 7 and/ornonwoven fabric sheet 8. Thenonwoven fabric sheets fabric sheet material 1 or forming a ring shape from the strip. - The method of producing the module functional roll X using the formed
nonwoven fabric sheets pressing machine 12 shown inFIG. 8A is used for producing the module functional roll X. Thepressing machine 12 has acylinder 1200, aframe 12a, and apressing collar 1201. -
FIG. 8B is an enlarged perspective view of a part of thepressing machine 12.FIG. 8B shows thecylinder 1200, one clampingjig 16, and a mountingshaft 2. The mountingshaft 2 has a hollow 2a, pores 2b, and lockinggrooves 2c. The hollow 2a is a hollow space inside the mountingshaft 2. Themultiple pores 2b are formed in the peripheral wall of the mountingshaft 2. Thepores 2b communicate with the hollow 2a. Themultiple locking grooves 2c extend in the axial direction of the mountingshaft 2 and situated at given intervals on the peripheral wall of the mountingshaft 2. The protrusions provided on the inner peripheral surface of thenonwoven fabric sheets grooves 2c. - The
pressing collar 1201 inFIG. 8A is movable in the vertical direction along theframe 12a. Thepressing collar 1201 comprises an insert hole for the mountingshaft 2 shown inFIG. 8B . - In the module functional roll X production process, first, as shown in
FIG. 9A , thenonwoven fabric sheets shaft 2 in sequence so that multiplenonwoven fabric sheets nonwoven fabric sheets shaft 2 inserted in theirholes nonwoven fabric sheets 8 are not shown (the same applies hereafter). Then, as shown inFIG. 9B , another clamping jig 17 (the second jig) is fitted on the mountingshaft 2 and additionally placed on top of a given number of stackednonwoven fabric sheets - After the additional placement, as shown in
FIG. 9C , the oneclamping jig 16 and stackednonwoven fabric sheets cylinder 1200 while the other clampingjig 17 is pressed with thepressing collar 1201. In this pressurizing/provisional clamping process, the stackednonwoven fabric sheets 7 and 8 (a nonwoven fabric sheet group) and the oneclamping jig 16 are pressed up while the other clampingjig 17 is pressed down.FIG. 9D shows the state after the pressurizing/provisional clamping process. Consequently, the stackednonwoven fabric sheets jigs nonwoven fabric sheets shaft 2 via the clamping jigs 16 and 17. In the pressurizing/provisional clamping process, pressurized by the pressingmachine 12, multiple strips of bridgingelastic bodies 100 scattered on the front andback sides fabric sheet material 1 are press-bonded to each other. After the pressurizing/provisional clamping process, as shown inFIG. 9E , restrainers 18 are mounted (the restrainer mounting process). Consequently, the clamping jigs 16 and 17 are immobilized to each other and the stackednonwoven fabric sheets - The above stacking, pressurizing/provisional clamping, and restrainer mounting processes are each performed once in sequence to provisionally form one module
functional roll 15. The stacking, pressurizing/provisional clamping, and restrainer mounting processes are collectively called "the module functional roll provisional-forming process."FIG. 9F is a perspective view showing a provisionally-formed modulefunctional roll 15. - In this embodiment, the module functional roll provisional-forming process is repeated multiple times to provisionally form multiple module functional rolls 15. More specifically, as shown in
FIG. 10A , the other clampingjig 17 with which the previous pressurizing/provisional clamping process is completed is used as the oneclamping jig 16 this time. Thenonwoven fabric sheets jig 17 with which the pressurizing/provisional clamping process is completed to stack multiplenonwoven fabric sheets nonwoven fabric sheets shaft 2 running through thenonwoven fabric sheets FIG. 10B , another clamping jig 17 (the third jig) is fitted on the mountingshaft 2 and additionally placed on top of a given number of stackednonwoven fabric sheets 7 and 8 (a nonwoven fabric sheet group consisting of multiple newly stacked nonwoven fabric sheets) (the stacking process). - After the additional placement, as shown in
FIGS. 10C and 10D , the pressurizing/provisional clamping process is performed.FIG. 10C shows the state before the pressurizing/provisional clamping process andFIG. 10D shows the state after the pressurizing/provisional clamping process. In the pressurizing/provisional clamping process, the stackednonwoven fabric sheets jigs nonwoven fabric sheets shaft 2 via the clamping jigs 16 and 17.FIG. 10E shows how therestrainers 18 are mounted after the pressurizing/provisional clamping process (the restrainer mounting process). - The above module functional roll provisional-forming process is repeated multiple times, and multiple module
functional rolls 15 are provisionally formed along the mountingshaft 2. - After multiple module
functional rolls 15 are provisionally formed along the mountingshaft 2, as shown inFIG. 11A , asuspension jig 20 is attached to the upper opening of the hollow 2a of the mountingshaft 2.FIG. 11B shows the state after thesuspension jig 20 is attached. After thesuspension jig 20 is attached, the multiple modulefunctional rolls 15 are suspended along with the mountingshaft 2 using a crane (not shown) and awire 21 as shown inFIG. 11C . The multiple modulefunctional rolls 15 are transported as shown inFIG. 11D . An enlarged view of the part in a broken-line circle inFIG. 11C is given below theFIG. 11C . The modulefunctional rolls 15 are secured by the restrainers 18 and clampingjigs - Then, a boiling process is performed. In the boiling process, a
hot water tank 22 shown inFIG. 12A is used. Thehot water tank 22 holds hot water. The temperature of the hot water is almost the boiling point. In the boiling process, as shown inFIG. 12B , the modulefunctional rolls 15 are immersed in the hot water along with the mountingshaft 2.FIG. 12C shows how the modulefunctional rolls 15 are immersed. The immersion time is approximately one to two hours. Because of the heat from the hot water, the strips of bridgingelastic bodies 100 scattered on the front andback sides fabric sheet material 1 undergo thermal fusion and adhere to each other, whereby the modulefunctional rolls 15 are united. In other words, thenonwoven fabric sheets functional rolls 15 do not adhere to each other because of the clamping jigs 16 and 17 in-between. - Because the mounting
shaft 2 has the hollow 2a andpores 2b, the hot water infiltrates evenly and the adhesion progresses efficiently and reliably. The hollow 2a and pores 2b of the mountingshaft 2 serve as fluid passages. - The boiling process is followed by a drying process. The
hot water tank 22 is also used in the drying process. More specifically, the hot water in thehot water tank 22 is drained (discharged) and thehot water tank 22 is used as a drying tank. In the drying process, first, as shown inFIG. 13A , a vacuum pump is connected to thehot water tank 22 via a hose in order to dry and/or cool the module functional rolls 15. For drying and cooling, the hollow 2a and pores 2b of the mountingshaft 2 serve as air passages. For drying and cooling, for example, hot air of approximately 80 °C is sent for 10 hours, which is followed by cooling. - After the drying process ends, as shown in
FIG. 13B , the modulefunctional rolls 15 are withdrawn from thehot water tank 22. Then, as shown inFIG. 13C , the modulefunctional rolls 15 are transferred again to thepressing machine 12 along with the mountingshaft 2. - Then, a disassembling process is performed. In the disassembling process, as shown in
FIG. 14 , starting with the lowest modulefunctional roll 15, the multiple modulefunctional rolls 15 are removed from the mountingshaft 2 in sequence by detaching therestrainers 18 and clampingjigs functional rolls 15 are subject to a finishing process such as surface polishing and clarification. Then, multiple module functional rolls X are produced. In the module functional roll X, thenonwoven fabric sheets - The module functional rolls X are packaged as they are and delivered to a customer such as a plant and processing place. Then, at the place where they are delivered such as a plant, the
functional roll 3 shown inFIG. 1 is finally assembled. - More specifically, multiple module functional rolls X are stacked with the
shaft body 300 running through thebore 300a, theflanges 302 are fitted on the ends of theshaft body 300, and thebearings 301 are provided on the ends, whereby thefunctional roll 3 shown inFIG. 1 is assembled. Consequently, the multiple module functional rolls X are united with theshaft body 300 inserted. This is an assembling work: thefunctional roll 3 can be produced simply and in a short time without skill. Furthermore, no special equipment (for example, the above-described pressing machine 12) is required for the assembling work. Therefore, the assembling work can be done at the customer's place. - In the case of delivering the module functional rolls X to the customer and finally assembling the
functional roll 3 at the customer's place as shown in the above embodiment, the module functional rolls X, which are smaller than thefunctional roll 3, are transported to the customer. Then, the transportation is facilitated compared with transporting the largefunctional roll 3. Furthermore, in the event that some of the module functional rolls X of thefunctional roll 3 have a failure, that module functional roll X can be replaced at the customer's place. - An embodiment of the present invention is described above. Other embodiments having the same object and characteristics naturally fall under the scope of the present invention. For example, in the above embodiment, the
nonwoven fabric sheets nonwoven fabric sheets 7 to produce a module functional roll X. In other words, one kind of nonwoven fabric sheets can be used to produce a module functional roll X. Alternatively, three or more kinds of nonwoven fabric sheets can be used to produce a module functional roll X. - In the above embodiment, the diameter of the circumference of the
nonwoven fabric sheets 7 is equal to the diameter of the circumference of thenonwoven fabric sheets 8. This is not restrictive. The outer diameter of thenonwoven fabric sheets 8 can be smaller than the outer diameter of thenonwoven fabric sheets 7. Furthermore, thenonwoven fabric sheets 8 can be made of the same material as thenonwoven fabric sheets 7. In the above embodiment, thehot water tank 22 is used as the drying tank. The drying tank can be prepared separately. However, if the hot water tank in the boiling process is also used as the drying tank in the drying process, the same place and the same tank make the work smooth and simple. It is possible to perform a vacuum process after the boiling process of the embodiment in which a hose provided to the mountingshaft 2 is connected to a pump to suck the water. - 1
