Abstract

A cushioning member is located between each support frame and the corresponding side of the shutter. The cushioning member (20) includes a pair of belt-shaped base members (21) and pile yarns (22) bridging between the base members (21). Some of the pile yarns (22) are cut at an intermediate portion (23) between the base members (21), which forms opposing first and second cut pile yarns with a cut in between. One of the base members (20) is attached to each support frame, and the other base member (20) contacts the shutter. The cut (23) permits the cushioning member to flexibly respond to movements of the shutter and satisfactorily exerts a cushioning function to suppress swaying of the shutter.

Description

SHOCK ABSORBING MEMBER AND MANUFACTURING METHOD OF THE SAME FIELD OF THE INVENTION The present invention relates to a damping member and a method for manufacturing the damping member. For example, the present invention relates to a damping member for a shutter apparatus including a pair of opposed support structures and a shutter for movement between the support structures, the damping member is interposed between the supporting structures and the supporting structures. opposite sides of the shutter.

BACKGROUND OF THE INVENTION Conventionally, as described in the Model of Japanese Utility Register No. 2592349, a silencing band structure has been proposed as a damper member for the shutter apparatus of the type mentioned above. More specifically, a silencing band body according to this silencing band structure includes a band-shaped sliding element and a band-shaped base, both formed of a hard material, such as hard vinyl chloride. The sliding element and the base are bridged with mohair so that the components of the sliding element, the base, and the mohair are integrated Ref. 163473 to substantially form layers of a unitary member. The silencer band bodies are mounted on guide rails via the bases, and have sliding elements slidably placed in connection with the front and rear surfaces of a shutter curtain mounted on the guide rails. When the shutter curtain opens and closes, the silencing band structure causes the sliding elements to slide smoothly on the front and back surfaces of the shutter curtain, helping the curtain to contravene to open and close smoothly. In the conventional shutter apparatus, the shutter curtain (like a shutter) attempts to move in all directions with respect to the guide rails (support structures), including both front-back directions and lateral directions, causing rocking movements. This occurs in several situations, including not only when driven by the wind but also when the shutter opens and closes. In response to such movements, when the shutter curtain moves in the front-rear directions, the silencing band body has the mohair as strands of hair folded between the sliding element and the base via the sliding element. This suppresses the generation of noise, such as crackling noise caused by the wind.

More specifically, the silencing band body has a damping function by the operation of the mohair which suppresses the movements of the shutter curtain in the front-rear directions originated, for example, by the wind impulse. However, when the shutter curtain moves in the lateral directions, the sliding element after the movement is extracted by the mohair located on the opposite lateral sides with respect to the movement direction thereof, which makes it difficult to move the element. Sliding, and which prevents the buffering function from being completely performed. Then again, when the conventional silencer band body is currently manufactured, it is possible to employ a method of forming a mohair member by adjusting the mohair on the sliding element or the base, arranging the ends of the mohair in order, raising the mohair, and other necessary operations, and then joining the base or the sliding element to the mohair of the mohair member. It is possible to employ another method of forming a pair of mohair members, and joining mohair ends of the mohair members together. Any method can be employed, it is necessary to form the mohair member beforehand, and therefore the manufacturing process is complicated. Furthermore, since the mohair is flexible, it is difficult to attach the mohair only by the ends of the mohair, or by aligning them, which makes it very difficult to manufacture the band body BRIEF DESCRIPTION OF THE INVENTION One object of the present invention is to provide a master member that performs a damping function Another object of the present invention is to provide a method of manufacturing a damping member, which is capable of easily and easily fabricating the damping member comprised of a pair of base members and bridged hair strands between the base members. To achieve the above objects, the present invention provides a cushion member that includes a pair of these members positioned in an opposite manner to each other and having a band shape, and a plurality of hair strands lying between the base members. Some of the pile yarns are cut at an intermediate portion between the base members to form first cut pile yarns and second cut pile yarns. The first and second cut hair strands face each other with a cut in between. The present invention also provides a method of manufacturing a cushion member. The method includes a wrapping stage for wrapping the hair strands around the surfaces of a continuous band while rotating the web; a base member supply step for supplying the pile yarns wound around the web a pair of base members which are in the form of a band from the opposite side sides of the web; a joining step for placing the supplied base members in contact with the pile yarns, and joining the base members to the pile yarns using ultrasonic waves; a cutting step for cutting the hair strands located in one of the inner and outer circumferences of the continuous band in the intermediate portion between the base members, forming a cut in the hair strands; and a separation step for separating the pile yarns together with the base members of the web via the cut.

BEST MODE FOR CARRYING OUT THE INVENTION Next, a first embodiment of the present invention will be described with reference to the figures. First, a description will be given of the construction of a shutter apparatus using damping members for a shutter apparatus. As shown in Figures 3 to 5, the shutter apparatus is comprised of a pair of support structures 12. placed straight on a floor 11 in an opposite manner to each other, a housing 13 bridging between the upper ends of the support structures 12, and a shutter 14 placed within the floor 11, the pair of support structures 12, and the housing 13. The support structures 12 function as guide members. The shutter 14, which functions as a mobile member, is formed by joining a plurality of vane plates 16 so that the vane plates 16 pivot relative to each other. The shutter 14 can be wound in a spiral manner by pivotally moving each vane plate 16. Furthermore, inside the housing 13, a hollow cylindrical drum, not shown, is rotatably supported, and an upper end of the shutter 14 is connected to an outer periphery of the drum. Further, when the drum rotates in one direction, the shutter 14 is wound around the outer periphery of the drum, and is received in the housing 13, which places the shutter apparatus in an open state. On the other hand, when the drum rotates in the other direction, the shutter 14 is unwound from the outer periphery of the drum, and removed from the housing 13, which places the shutter apparatus in a closed state. The support structures 12 each are formed as a hollow square metal pole, and each structure of Support 12 has a guide groove 15 formed between the inner end faces thereof so that the guide groove 15 opens towards the interior of the shutter apparatus. The shutter 14 has opposite ends. One of the opposite ends is inserted into the guide groove 15 of each of the support structures 12. When the opening or closing operation is performed to place the shutter apparatus in the open or closed state, each structure of Support 12 functions to support the shutter 14 while guiding the shutter 14 in the guide grooves 15 so that the shutter 14 can vertically correspond. In addition, each guide groove 15 has opposed internal surfaces each of which is formed with a linear receiver recess 17. The receiver linear recesses 17 extend along the longitudinal direction of the structure 12 and open towards the front surface and the rear surface of the shutter 14. These receiving linear recesses 17 each have open ends thereof formed with a pair of protrusions 18, whereby the opening of the receiving linear recesses 17 is limited to a predetermined width. The openings are formed between one of the inner surfaces of each guide groove 15 and the front and between the other inner surface of the guide groove 15 and the rear surface of the shutter 14, respectively.

The damping members 20 for a shutter apparatus respectively are received in the linear recesses 17 so that the damping members 20 block the openings. Next, the construction of the cushion member 20 will be described. As shown in Figs. 1 to 2 (e), the cushion member 20 is comprised of base members 21 having a band shape and positioned in an opposite manner to each other, and a plurality of hair strands 22 fitted on the shoulders. base members 21 in a way that bypasses the pair of base members. The base members 21 are formed of a synthetic resin film having excellent wear resistance and a low coefficient of kinetic friction. Examples of such a synthetic resin include olefinic resins, such as polyethylene polymer and ultra high polypropylene; amia resins, such as aliphatic polyamides and aromatic polyamides; acrylic resins, such as polyacryl; ester resins, such as polyethylene terephthalate; Fluorocarbon resins, and so on. Further, in an intermediate portion in the width of each base member 21, a pair of linear guide protrusions 21a is formed which extend along the length of the base member with a predetermined opening between the pair of protrusions. The pair of linear guide protrusions 21a are parallel to each other to the position of the pile yarns 22. The pile yarns 22 are folded in a U-shape, and the folded portion of the pile yarns 22 is inserted between the two Linear guide protrusions 21a. The methods of joining the hair strands 22 to the base member 21 include using an adhesive or ultrasonic waves, heat application welding, and so on, of which a suitable one is selected as desired. Among them, the ultrasonic bond is preferable since the base member 21 and the hair strands 22 can be firmly joined together, and changes in the shape of the hair strands 22 can be suppressed except in the attached portion of the hair strands 22. the same . The pile yarns 22 are formed of fiber yarns having a high durability and excellent in a recovery property and a non-water absorption property, such as filament yarns, spun yarns, or fimilar yarns. Examples of such fibers include synthetic fibers made from synthetic resins mentioned relative to the base members 21, semi-synthetic fibers made of rayon or the like, natural fibers made of cotton or the like, etc. Among these, particularly synthetic resins made of olefinic resins, such as polypropylene; Amide resins made, for example, from aliphatic polyamides and aromatic polyamides have a excellent recovery property to recover from the compressed state, which makes them more preferable as fibers for the pile yarns 22. Furthermore, when the pile yarns 22 are attached to the base member 21 by ultrasonic bonding, it is further preferable to use a synthetic resin that is of the same family as that used for the base member 21. As shown in Figures 4 and 5, the cushion member 20 is fixed to the guide groove 15 of the support structure 12 having a first base member 21 inserted in the linear receiver recess 17. In addition, the second base member 21 of the damper member 20 is supported on the pile yarns 22 projecting from the opening of the linear receiver recess 17, and at the same time is driven on the front surface or rear surface of the shutter 14 by the same hair strands 22, to be brought into contact with it. The shutter 14 is supported by a pair of damping members 20 in a manner interspersed from the front and rear sides. When the shutter is opened and closed, the shutter 14 is made to correspond vertically with the front and rear surfaces thereof being slid over the second base members 21 of the cushion members 20. At this time, since the second members of base 21 are formed from the synthetic resin that has a low coefficient of kinetic friction, the shutter 14 slides on the damping members 20, whereby the damping members 20 perform the function of reducing the sliding resistance offered when the shutter is opened and closed. When the shutter is opened and closed while the shutter is driven by the wind, or at similar times, the shutter 14 is propelled towards the second base members 21 due to the crackling or rocking movement thereof. At this time, the shutter 14 is received by the hair strands 22 via the second base members 21, and is driven again, whereby the shock absorbing members 20 suppress the crackling and rolling movements of the shutter 14. To make possible that the cushion members 20 perform satisfactorily the function of reducing the resistance and the damping function, the pile yarns 22 have a single yarn fineness of 5 to 110 decitex, more preferably 10 to 70 decitex, additionally preferably 10 to 35 decitex. Conventionally, a strand (strand of multiple strands) formed by co-twisting a plurality of strands, or fibers, is used for a strand of hair 22. The term "single strand fineness" refers to a degree of fineness of a strand in a strand. single hair thread 22. When the fineness of single thread is decreased, the rigidity of the pile yarns 22 is decreased, which may undesirably inhibit the cushion members 20 from completely accomplishing a desired cushioning function, and may cause inconveniences, such as performance of the hair yarns 22. When the fineness of single yarn it increases, the flexibility of the hair strands 22 decreases, which causes the second base member 21 to be pressed against the shutter 14 with a strong force. This makes it impossible for the damper members 20 to completely perform the strength reduction function, causing inconveniences when the shutter 14 is opened and closed. In addition, the fineness of the pile yarn 22 itself is preferably 100 to 2200 decitex, more preferably 500 to 2200 decitex, most preferably 600 to 1650 decitex. In some cases one. strand (monofilament strand) formed by a single filament, instead of a strand of multiple filaments, is used for the hair strand 22. For excellent performance of the function of reduction of resistance and the damping function, it is preferred that the fineness of the hair thread 22 - same as - described as described above. In addition, when the fineness of the pile yarn 22 is decreased, the rigidity of the pile yarns 22 is decreased, which makes it impossible for the shock absorbing members 20 to fully perform the desired damping function. When the The fineness of the pile yarn 22 increases, the flexibility of the pile yarns 22 decreases, which makes it possible to completely carry out the strength reduction function. The number of pile yarns 22 adjusted in the base member 21 is preferably 1000 to 10000 per inch along the length of the base member 21, more preferably 1000 to 8000, most preferably 1500 to 6500. When the number of hair strands 22 per inch along the length of the base member 21 decreases, the density of the hair strands 22 on the base member 21 decreases, which makes it easier to form the space between the hair strands 22. When the density of the pile yarns 22 is decreased, the pile yarns 22 can not be supported together, which decreases the stiffness of the full pile yarns 22. This makes it impossible to sufficiently receive the shutter 14, and to completely perform the damping function. When the number of strands of hair 22 per inch increases, the density of the strands 22 on the base member 21 becomes greater, which causes the strands 22 to be responsible for being excessively dense. When the density of the pile yarns 22 consequently becomes excessively dense, the flexibility of the full pile yarns 22 becomes low, so that the second base member 21 originates to be depressed against the shutter 14 with a strong force, which increases the sliding resistance, making it impossible for the damper members 20 to fully perform the function of resistance reduction. . As shown in FIGS. 1 to 2 (e), part of the pile yarns 22, specifically, the pile yarns 22 that fit toward one side of the center in the width direction of the base member 21 are cut to intermediate portion between the base members 21. The cut pile yarns 22 include first cut pile yarns 22 extended from the first base member 21, and second cut pile yarns 22 extended from the second base member 21. The distal ends (cut ends) of the first cut pile yarns 22 and the distal ends (cut ends) of the second cut pile yarns 22 face each other with the cut 23 in the middle. The cut 23 is formed so that it extends along the length of the base member 21 over the entire length of the cushion member 20. The cut pile yarns 22 are opened to have ends thereof extended apart. The distal portion of the cut pile yarns 22 is buckled in a lateral direction relative to the length of the base members 21. Therefore, the cut pile yarns 22 are denser in the proximal portion than in the distant portion. . The hair strands 22 differ from the cut pile yarns 22, ie, the uncut hair strands 22 connecting the base members 21 to each other flex between the base members 21 to buckle in a lateral direction relative to the length of base members 21. Therefore, uncut hair strands 22 are denser in the proximal portion than in the intermediate portion. The hair strands 22 as a whole expand in a central portion thereof between the two base members 21 in opposite lateral directions with respect to the longitudinal direction of the base members 21, whereby the cross section perpendicular to the length of the base members 21 is approximately diamond-shaped. The flexed portion of the uncut hair strands 22 is more easily bent compared to straight hair strands. If the pile yarns 22 are compressed when the pile yarns 22 receive external force via the second base member 21 when the shutter 14 moves, the pile yarns 22 generate elastic force to recover the original shape. The damping function of the damper member 20 is exhibited by the elastic force. However, when the elastic force of the pile yarns 22 is increased, the second base member 21 is pressed excessively against the shutter 14 with a greater force, which increases the sliding resistance of the shutter 14 to the damping members 20, to make it impossible for the damping members 20 to fully perform the strength reduction function. Therefore, in this embodiment, the damping members 20 are formed with the cut 23, whereby the damping function and the resistance reduction function are suitably performed depending on the situation. More specifically, the damping members 20 perform the damping function and the resistance reduction function in a well-balanced manner when they receive a weak external force. When receiving a strong external force, the damping members 20 perform the damping function preferentially on the strength reduction function. When the shutter 14 swings during the opening and closing of the shutter 14, the damping members 20 receive a relatively weak external force. When the shutter 14 is driven by the wind, the damping members 20 receive a relatively large external force. More specifically, when a weak external force is applied to the damping members 20 when the shutter 14 moves back and forth, the uncut hair strands 22 are bent and the complete uncut hair strands 22 are folded uniformly to generate the elastic force. On the other hand, in the hair strands cut 22, the ends of the first cut pile yarns 22 or the second pile yarns 22, with the cut 23 in between, enter between the ends of the other cut pile yarns 22. Therefore, the cut pile yarns 22 do not generate elastic force. This softens the elastic force applied from the full pile yarns 22 to the shutter 14. Therefore, when the external force is weak, the damping members 20 generate only an elastic force corresponding to the external force, but appropriately perform the damping function. to a necessary and sufficient degree to thereby eliminate the rolling of the shutter 14 and the generation of unusual noise, such as crackling, when the shutter 14 is opened and closed. Furthermore, since only the elastic force corresponding to the external force is generated, the damping function and the resistance reduction function are performed in a well balanced manner, therefore the operation of opening and closing the shutter 14 is performed properly. When the external force applied to the damping members 20 is relatively strong, the ends of the first cut pile threads 22 or the second pile threads 22, with the cut 23 in between, go deep between the ends of the other hair strands cut 22. In this time, since the hair strands cut 23 are more dense towards the proximal ends, the first and second cut pile yarns 22 are easily hooked together, which increases the resistance generated when the cut pile yarns 22 are coupled together. Alternatively, the ends of the cut pile yarns 22 engage the base members 21. This causes the cut pile yarns 22 to curve in a similar manner to the uncut yarns 22, and all of them uniformly it bends to generate the elastic force. When the external force applied to the damping members 20 increases, the resistance generated when the first or second cut pile yarns 22 facing into the other cut pile yarns 22 increases, or the number of the cut pile yarns 22 which they are hooked together if it increases. Accordingly, the elastic force generated by the cut pile yarns 22 is increased. Therefore, when the applied external force is relatively strong, the damping members 20 perform the damping function preferentially on the strength reduction function, thereby generating strong elastic forces capable of sufficiently receiving the strong external force. As a result, the cushion members 20 suppress the large movement of the shutter 14, as well as the generation of large unusual noise, such as crackling noise caused by the wind . The cushion members 20, each having a length of 10 years, were currently produced using pile yarns 22 made of polypropylene and having a fineness of 1350 decitex / 52 filaments, so that 1800 yarns were adjusted per inch along the length of the yarn. the length of the base members 21, and a distance between the base members 21 was equal to 7 mm. Then, the cushion member 20 was compressed in the extension direction of the pile yarns 22 (in a direction that decreases the distance between the base members 21), and the elastic force generated by the cushion members 20 was measured. The result of the measurement showed that until the amount of compression became equal to 2 mm, the elastic force increased linearly in proportion to the compressive force, and that when the amount of compression exceeded 2 mm, the elastic force increased. in a more than corresponding curve with the compressive force. Further, when the shutter 14 moves laterally, as shown in FIGS. 6 (a) and 6 (b), the first and second cut pile yarns 22, which face each other with the cut 23 in the middle, are they place laterally with respect to each other (in a lateral direction as seen in figures 6 (a) and 6 (b)). This makes it possible for the second base member 21 to flexibly follow the movement of the shutter 14, and the cushion member 20 always maintains contact between the second base member 21 and the shutter 14. Therefore, the damping members 20 flexibly follow all the movements of the shutter 14, and perform fully the damping function and the strength reduction function described above. Next, the construction of an apparatus for manufacturing the cushion member 20 will be described. As shown in Figures 7 (a) and 7 (b), the manufacturing apparatus includes a continuous band 51 formed by connecting the opposite ends of a member. in the form of a band. The web 51 extends around a plurality of rollers 52. Assuming that a left side end as seen in the figures is a start end and a right side end thereon is a terminus end, the web 51 is rotates inside the apparatus when the rollers 52 on the start end side are driven by a rotary pulse apparatus 50. Between the rollers 52 on the start end side and the rollers 52 on the end end side, is arranged a hair yarn supply section 54, a base member supply section 55, a joining section 56, a cutting section 57, and a collection section 58, in the order of the start end side end side of termination The hair strand supply section 54 includes a pair of reels 59 opposite each other with the web 51 between them. The reels 59 are configured to rotate about an axis along the extended direction of the web 51 while supplying the pile yarns 22 on the surface of the web 51. The base member supply section 55 includes a pair of supply drums 60 opposed to each other, with the web 51 between them. Each supply drum 60 has the base member 21 received therein in a rolled state around it, and the uncoiled base members 21 of the supply drum 60 are supplied to the opposite side sides of the web 51 to hold the band. continues 51, so that the supplied base members 21 move in parallel with the web 51. The link section 56 includes a pair of speakers 61 for transmitting ultrasonic vibrations to the base members 21 and a pair of thrust members. 61 for driving the base members 21 against the continuous band 51. Each speaker 61 forms a pair with one of the push members 62. Each pair of one of the horns 61 and the associated push member 61 intersperses the web 51, and the two pairs are arranged in an alternate configuration with respect to the direction of rotation of the web 51. That is, the first speaker 61 faces the first push member 62, and the second speaker 61 faces the second push member 61. The cutting section 57 includes a cutting blade 63 which faces the internal or external circumference of the web 51. In Figs. 7 (a) and 7 (b), the cutting blade 63 faces the internal circumference of the web 51, and the cutting blade '63 is placed in the web. center in the direction of the width of the web 51. The collection section 58 has a collection drum 54 positioned to one side of the web 51, and the fabricated cushion members 20 are taken in the collection drum 64, for be collected Next, a description will be given of a method of manufacturing the damper member 20 using the above manufacturing apparatus. The cushion member 20 is made through a wrapping step, a base member supply step, a joining step, a cutting step, and a separation step. The wrapping step is performed to wrap the pile yarns 22 around the surfaces of the web 51, and is executed by the hair yarn supply section 54 of the manufacturing apparatus. In the hair yarn supply section 54, the pair of spools 59 supplies hair yarns 22 on the web 51 while rotating around the web 51. Then, the hair yarns 22 supplied on the web 51 wrap around the surfaces of the web 51 in a spiral manner, and they move toward the terminating end in conjunction with the web 51. The base material supply step is performed by supplying the base members 21 from the side sides of the web 51 to the hair strands wound around the web 51 , and is executed by the base member supply section 55 of the manufacturing apparatus. In the base member supply section 55, the unwound base members 21 of the respective supply drums 60 are provided so that the base members 21 are positioned on the opposite side sides of the web 51. At this time , the positioning is carried out in such a way that the hair strands 22 wound around the web 51 are positioned between a pair of linear guide protrusions 21a provided in each base member 21. The joining step is carried out by bridging the base members supplied 21 in contact with the hair strands 22 and causing the base members 21 and the hair strands 22 to be joined together using ultrasonic waves, and executed by the attachment section 56 of the apparatus manufacturing. In the joining section 56, while each pushing member 62 urges one of the base members 21 from a lateral side of the web 51 to bring them into contact with the hair strands 22, the horns 61 come into contact with the other base member 21 from the other lateral side of the web 51. Then, the ultrasonic vibrations are transmitted via the speakers 61 to the base members 21, and due to the vibrations of the ultrasonic waves, the base members 21 and the hair strands 22 are joined at the site where they are in contact with each other. The cutting step is performed to cut the hair strands 22 into an intermediate portion of the base members 21 at one of the inner and outer circumferences of the web 51, to form the cut 23, and is executed by the cross section of the web. cutting 57 of the manufacturing apparatus. In the cutting section 57, a center of the lower half of the pile yarns 22 wound around the web 51 is cut by the cutting blade 63 facing the internal circumference of the web. As a result, the cushion member 20 having the cut 23 is made in a manner covering the web 51. The separation step is performed by separating the hair threads 22, together with a pair of base members 21, via the cut 23 from the other side of the web 51, and is executed by the collection section 58 of the manufacturing apparatus. In the collection section 58, the cushion member 20 on the web 51 is pulled upwards, either by rotation of the drum 64 or manual operation of the workers. This causes the first and second cut pile yarns 22 facing each other with the cut 23 in the middle to bend, expanding the cut 23, whereby the cushion member 20 is extracted from the web 51, and is separated from the band. continuous 51. Then, the manufactured cushion member 20 is wound around the collection drum 64, to be collected. The following gives a description of the advantages exhibited by the previous modality. The cushion member 20 of the present embodiment includes a pair of base members 21, and bristles 22 bridged between the base members 21. Some of the hair yarns 22 are cut in the intermediate portion between the base members 21, forming the first and second cut hair strands 22 facing each other with the cut 23 in between. By providing the cut 23, the hair strands 22 appropriately perform the damping function and the resistance reduction function in a well-balanced manner, in response to a relatively weak force applied to them, for example, by rolling shutter 14 which occurs when the shutter 14 opens and closes, and preferentially perform the buffer function in response to a relatively strong force applied to these, for example, by wind impulse. Further, when the shutter 14 is laterally balanced, the first and second cut pile yarns 22 move laterally relative to each other with the cut 23 as a limit in a manner that is handled with the movement of the shutter 14, thereby the state of the shutter 14 being in contact with the second base members 21 is maintained. This makes it possible for the damping members 20 to respond flexibly to the movements of the shutter 14, and thus to perform the damping function of suppressing the rolling of the shutter 14. The hair strands 22 are formed so that the cross section perpendicular to the The length of the base members 21 is generally diamond-shaped. Therefore, in response to a relatively weak external force applied to the damping members 20 by the shutter 14, some of the hair strands 22 (uncut hair strands 22) are bent whereby both the damping function and the function of resistance reduction that cause the shutter 14 to open and close smoothly can be performed in a well-balanced manner. In addition, in response to a relatively strong external force applied to the cushion members 20 by the shutter 14, the full pile yarns 22 (the yarns of cut hair 22 and the uncut hair strands) are bent whereby the damping function is preferentially performed to suppress the movement of the shutter 14 and the generation of unusual noise such as crackling noise caused by the wind. The cushion member 20 is fabricated through the wrapping step to wrap the pile yarns 22 around the surfaces of the web 51, the base member supply step for supplying the base members 21 from the opposite side sides. of the pile yarns 22, the joining step for joining the base members 21 to the pile yarns 22 by ultrasonic waves, and the cutting step for cutting some of the pile yarns 22 to form the cut 23. In addition, in the separation step, the cushion member 20 thus made is separated from the web 51 via the cut 23, and collected. This makes it possible to manufacture the damping members 20 almost automatically using the manufacturing apparatus without performing complicated operations. Therefore, it is possible to easily and reliably fabricate the damper member 20 comprised of a pair of base members 21 and bristles 22 bridged between the base members 21. Figure 8 illustrates an example in which the damper members 20 they use as support members to support the sides of a door or a wire mesh window 70. The damping members 20 are attached to the side structures 71 of a door or a window (only one of the side structures is shown in figure 8). Each side structure 71, which is a guide member, has a guide groove 72 that extends vertically (in a direction perpendicular to the elevation of Figure 8). A vertically extended linear receiver recess 17 is formed on each of the internal sides of the guide groove 72 facing each other. The damper member 20 is fixed to the guide groove 72 of the side structure 71 having base members 21 inserted into the linear recesses 73. Each side of the wire cloth 70, which is a movable member, is located at one of the guide grooves 72, and the wire cloth can be moved up and down along the guide grooves 72. Each side section of the wire cloth 70 is inserted into a cut 23 of one of the cushion members 20. The first cut pile yarns 22 and the second cut pile yarns 22, which face each other with the cut 23 in the middle, maintain the side section of the metal fabric 70 and support the metal fabric 70 from the front sides and rear. Therefore, the wire cloth 70 is raised and lowered with the side sections that are held by the cushion members 20, while sliding over the wires cut hair 22. The cut pile yarns 22 satisfactorily perform a damping function to suppress the shaking of the wire cloth 70 forward and backward (in a vertical direction as seen in Figure 8). On the other hand, the uncut hair strands 22 of the shock absorber member 20 receive a side edge of the wire cloth 70, and exert a satisfactory damping function to suppress the shaking of the wire cloth 70 in the width direction (shake to the left). and right as seen in figure 8). As described above, the damping member 20 is not only applicable to the shutter apparatus, but can also be used as support members for the wire gauze 70. Different from the support members for the wire gauze 70, the damping member 20 is it can be used as support members for various types of sheet members and plate members, such as panels and glass sheets. In this case, the cushion member 20 can be used for fixed sheet members or sheet members or for plate members or sliding sheet members. In addition, the cushion member 20 can be attached to the edge of a wire mesh fabric. In this case, the distal ends of the cut pile yarns 22 of the shock absorber member 20 mesh with the mesh of the metal mesh, so they work to prevent the entry of small animals such as insects. Now a third embodiment of the present invention will be described with reference to Figures 9 and 11 (c). The differences of the first modality of figures 1 to 8 will mainly be discussed. As shown in Figure 9, a damper member 120 in this embodiment is different from the damper member 20 of Figure 1 in that a film 80 extends between the base members 21. The film 80 is located centrally in the direction in width of the base members 21, and extends along the entire length of the cushion member 120 in the longitudinal direction of the base members 21. The cut pile yarns 22 are provided on one side of the film 80, and the uncut hair strands 22 are located provided on the other side of the film 80. The film 80 is formed of a material having a high durability and excellent in a recovery property and a non-water absorption property. Preferably, the film 80 is formed of a polypropylene sheet. The thickness of the film 80 is selected in accordance with the use of the cushion member 120. In a case where a high flexibility of the cushion member 120 is primarily required, a relatively thin film is used as the film 80. In a case where a high load carrying capacity is required, a relatively thin film is used as the film 80. In a case where the shock absorbing member 120 having the film 80 is applied to the shutter apparatus shown in figure 4 instead of the shock absorbing member 20 of Figure 1 which does not have film 80, the following advantages are obtained. That is, compared to the cushion member 20 that does not have film 80, the cushion member 120 having the film 80 has a greater elastic force (elastic force), and has a better protective effect against foreign matter and liquids. Therefore, in a situation where the damping member receives relatively large load from the shutter 14 of the shutter apparatus, the damping member 120 having the film 80 is preferably applied to the shutter apparatus. Further, if the cushion member 120 having the film 80 is applied to the shutter apparatus, wind, rain, and dust are reliably prevented from entering the interior of the support structure 12. Since the film 80 is located in the center in the width direction of the damping member 120, the damping member 120 is deformed by the received load in a well-balanced manner, and consequently performs the damping function and the resistance reduction function in a satisfactory manner.

Fig. 10 illustrates an example in which the damping member 120 of Fig. 9 is used as a support member for a glass pane 90 of a sliding window. The cushion member 120 is attached to a lower structure 91 of the sliding window so that the cut 23 faces upwards. The lower structure 91, which is a guide member, has a guide groove 92 extending horizontally (in a direction perpendicular to the elevation of Figure 10). The base members 21 of the shock absorber member 120 are fixed to the internal sides of the guide groove 92 facing each other. The coupling positions of the pile yarns 22 to the base members 21 move from the center of the width of the base members 21, so that the uncut hair strands 22 contact the bottom of the guide groove. 92. The underside of the glass sheet 90, which is a movable member, is located in the guide groove 92, and the glass sheet 92 can be moved horizontally along the guide groove 92. The side bottom of the glass sheet 90 is inserted into the cut 23 of the cushion member 120. The first cut pile yarns 22 and the second cut pile yarns 22, which face each other with the cut 23 in between, maintain the section bottom end of the glass sheet 90 and support the glass sheet 90 from the front and back sides. Therefore, the glass sheet 90 moves with the lower end section being held by the cushion member 120, while sliding on the cut pile yarns 22. The cut pile yarns 22 satisfactorily perform a buffer function to prevent that the glass sheet 90 is shaken forward and backward (left and right as seen in Figure 10). On the other hand, the film 80 receives the lower edge of the glass sheet 90. To carry the load applied by the glass sheet 90, a relatively thick material is preferably used as the film 80. Specifically, a polypropylene sheet having a thickness that is greater than the size of the hair strands 22 is preferably used as the film 80. Part of the uncut hair strands 22 between the bottom portion of the guide groove 92 and the film 80 functions, together with the 80 film, as a shock absorber to receive the vertical load. Accordingly, glass sheet 90 is satisfactorily prevented from shaking vertically, and vertical impacts are absorbed satisfactorily. Similar to the cushion member 20 of Figure 1 which has no film 80, the cushion member 120 of Figure 9 having the film 80 can be used as a support member for various types of blade members and different plate members of the support member for the glass sheet 90. For example, the damper member 120 having the film 80 can be applied to the wire cloth 70 shown in the figure 8, doors, and panels. In this case, the cushion member 20 can be used for fixed sheet members or sheet members or for plate members or sliding sheet members. Figs. 11 (a) to 11 (c) illustrate an apparatus for manufacturing the cushion member 120 shown in Fig. 9. The manufacturing apparatus shown in Figs. 11 (a) and 11 (b) is formed by adding a supply section of film 65 to the manufacturing apparatus shown in Figures 7 (a) and 7 (b). The film supply section 65 is located upstream of the hair strand supply section 54. The film supply section 65 has a coil 66 for accommodating the film 80 in a rolled state. The film 80 extracted from the reel 66 is supplied to the outer circumferential surface of the web 51, and then, in conjunction with the web 51, is supplied to the hair yarn supply section 54. The cushion member 120 is made through, after the film supply stage, the wrapping stage, the base member supply step, the joining step, the cutting step and the separation step.

The film supply step is performed to supply the film 80 to the outer circumferential surface of the web 51, and is executed by the film supply section 65. The film 80 withdrawn from the coil 66 is supplied to the circumferential surface of the web 51, and covers the external surface of the web 51 (see Figure 11 (c)). In the next wrapping stage, the pile yarns 22 supplied by the pair of the reels 59 are wrapped around the web 51 covered with the film 80 (see Figure 11 (c)). Then, in the same manner as the procedure shown in FIGS. 7 (a) and 7 (b), the base member supply step, the joining step, the cutting step, and the separation step are performed. Particularly, in the joining step, the base members 21, the hair strands 22, and the film 80 are joined together in the contact areas by ultrasonic wave vibrations generated by the horns 61. A third embodiment of the present invention will now be described. the present invention with reference to figures 12 to 15 (c). The differences of the second modality of Figures 9 to 11 (c) will mainly be discussed. As shown in Figure 12, a cushion member 220 in this embodiment has a film 80 stretched between the base members 21 similar to the member. damper 120 of figure 9. However, this damper member 220 of this embodiment is different from the damper member 120 of figure 9 in that the film 80 is located outwardly from the hair strands 22. The film 80 covers the strands of uncut hair 22 on an opposite side of the cut 23. Figure 13 illustrates an example in which the damping members 220 of Figure 12 are used in a shutter apparatus. The damping members 220 are attached to the support structure 12 so that the cuts 23 face the interior of the support structure 12, or the film 80 faces outwardly from the support structure 12. Since the films 80 face outward, this configuration has a better protective effect compared to a case where the damper member 120 of Figure 9 is applied to a shutter apparatus. In addition, since the hair strands 22 are covered from the outside of the support structure 12 with the film 80, the hair strands 22 are prevented from being contaminated. Figure 14 illustrates an example in which the damping member 220 of Figure 12 is used in a ventilation system. The ventilation system includes a blower apparatus 95 and a conduit 96 extended from the blower apparatus 95. The cushion member 220 is located between the blower apparatus 95 and the duct 96. The cushion member 220 hermetically connects the blower apparatus 95 to the duct 96. One of the base members 21 is attached to the blower apparatus 95, and the other base member 21 is attached to the duct 96. The film 80 is arranged to face the outside. The blower apparatus 95 has a motor (not shown) and generates an air flow in the duct 96 activating the motor. The damper member 220 having the film 80 prevents air from leaking from the junction between the blower apparatus 95 and the conduit 96 and forms an air-tight space between the blower apparatus 95 and the conduit 96. In addition, the damper member 220 it allows the blower apparatus 95 and the duct 96 to move relative to each other, thereby preventing the vibrations generated by the motor from being transmitted from the blower apparatus 95 to the duct 96. That is, the damping member 220 functions satisfactorily as a seal air tight and a vibration moderator. Figures 15 (a) to 15 (c) illustrate an apparatus for manufacturing the damper member 220 shown in Figure 12. The manufacturing apparatus of Figures 15 (a) and 15 (b) is different from the apparatus for making the Figures 11 (a) and 11 (b) in which the film supply section 65 is located between the hair strand supply section 54 and the base member supply section 55. The cushion member 220 is made by performing the film supply stage after the wrapping stage, and then performing the base member supply step, the joining step, the cutting step, and the separation step. In the film delivery stage, the film 80 is supplied to the pile yarns 22, which have been wrapped around the web 51 in the wrapping stage, from the outer circumference of the web 51. The film 80 taken from the reel 66 of the film supply section 65 covers the pile yarns 22 on the outer circumferential surface of the web 51 (see Figure 15 (c)). In the base member supplying step, the base members 21 unwound from the respective supply drums 60 are provided so that the base members 21 are positioned on the opposite side sides of the web 51. At this time, the positioning is performed so that each side section of the web 51 is located between the linear guide projections 21a of the base members 21, and the end faces of the film 80 are folded to include the hair strands 22 on the web continue 51 (see Figure 15 (c).) Next, in the same manner as the procedure shown in Figures 11 (a) and 11 (b), the joining step, the cutting step, and the separation step are carried out. It should be noted that these modalities are can modify to provide the following variations of them. As shown in Figs. 16 (a) to 16 (c), a attached damping member 300 can be formed by connecting a pair of the damping members 20 of Fig. 1. The attached damping member 300 is formed by positioning the two damping members 20. side by side and engaging each adjacent pair of the base members 21. The adjacent base members 21 are coupled together with an adherent member 301, which is, for example, an adhesive tape or a Typar (a registered trademark of Du. Pont). In Figure 16 (a), the damping members 20 are engaged so that the cuts 23 face the same direction. In Figure 16 (b), the cushion members 20 are engaged so that the cuts 23 face away from each other (facing outwards). In Figure 16 (b), the cushion members 20 are engaged so that the cuts 23 face each other (faced inwardly). Figure 17 illustrates an example in which the attached damping members 300 of Figure 16 (a) are used in a shutter apparatus. Since the attached damping members 300 contact the shutter 14 in a large area, the shutter 14 is more satisfactorily prevented from shaking and vibrating than a case where the damping members 20 of Figure 1 are used. It is useless mention that the Buffer member United 300 of Figures 16 (b) and 16 (c) can be applied to a shutter apparatus. Any of the attached damping members 300 shown in Figures 16 (a) to 16 (c) is selected according to the type of shutter apparatus and the environments in which the shutter apparatus is installed. Although not illustrated, each of the attached damping members 300 shown in Figures 16 (a) to 16 (c) can be formed by coupling a pair of the damping members 120 shown in Figure 9 or by coupling a pair of damping members. 220 shown in Fig. 12. In this case, the attached damping member 300 can be applied to an apparatus that requires airtightness, such as the ventilation system shown in Fig. 14. In addition, each of the attached damping members 300 shown in FIG. Figures 16 (a) to 16 (c) can be formed by engaging any two of the damping member of Figure 1, the damping member 120 of Figure 9, and the damping member 220 of Figure 12. At least one of the members of base 21 and the hair strands 22 can be given with weather resistance. Weatherability can be given by a method for mixing a weathering agent in a synthetic resin used for the base members 21 or the hair strands 22, a method for coating the base members 21 or the hair strands 22 with a processing liquid containing the weathering agent, and so on. As the weathering agent, mention may be made of a hindered amine-based light stabilizer, a benzotriazole-based ultraviolet light absorber, etc. This configuration can improve the durability of the base members or the hair strands. In the damping members 120, 220 each has the film 80, the film 80 can also be provided with weather resistance in the same manner. The base members 21 are not limited to a film, but can be formed by a woven fabric, knitted fabric, a non-woven fabric, a sheet, or the like, made of a synthetic resin. The shutter apparatus is not limited to a type that is vertically open and closed, but other types that open and close horizontally, including a type that opens and closes in a front to back direction and a type that opens and it closes in a direction from left to right, or a type that once opens / closes in ^ a direction from front to back and then opens / closes vertically, can be done. The back surface of the first members of base 21 fixed to each support structure 12 in the shutter apparatus can be formed with a layer of adhesive, for example, by applying a pressure sensitive adhesive agent, such as a rubber based agent or an acrylic based agent , or a double-sided adhesive tape formed by coating a pressure-sensitive adhesive agent on both sides of a core material. Then, the cushion member 20 can be attached to the inner bottom surface of the receiver linear recess 17 via the adhesive layer. Alternatively, the support structure 12 can be formed by omitting the receiver linear recesses 17 or the guide slot 15, and the buffer member 20 can be attached to a predetermined location of the support structure 12 via the adhesive layer. When the damping members are applied to a device other than the shutter apparatus, it is useless to mention that the base members 21 can be attached to an object via the adhesive layer. In the manufacturing method according to the illustrated embodiments, the cushion member 20 (120, 220) is separated from the web 51 and then wound around the collection drum 64, to be collected. This is not limiting. That is, after the cushion member 20 (120, 220) is removed and separated from the web 51 by the manual operation of the workers, the cushion member 20 (120, 220) when separated can be cut to a desired length without being rolled up, to be collected as cushion members 20 (120, 220) having a linear shape. When configured as described above, the collection drum 64 can be omitted, and the construction of the manufacturing apparatus can be simplified. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention.
