Description

  The present invention relates to a metal wire wrapping tape material and a long coated material comprising the metal wire wrapping tape material.

Flexibility and porosity by forming metal wires instead of metal plates and foils for the purpose of reinforcement against electromagnetic waves and other objects such as cables and rods (hereinafter referred to as “long materials”) In some cases, a long material is covered with a covering material having air permeability. Conventionally, various kinds of coating materials have been proposed.
For example, as a coating material of the first example, while braiding a metal wire that easily causes plastic deformation such as copper or aluminum into a tubular shape using a braid-like technique, the braided intersection generated during the braiding is pressed down in the cylinder axis direction. A sleeve is known that is plastically deformed so that the metal wires do not move independently (no gap is generated between the metal wires) (see Patent Document 1).

Further, as a covering material of the second example, a primary tubular knitted product is obtained by knitting a metal wire that easily causes plastic deformation such as copper or aluminum by a tubular knitting machine, and then the primary tubular knitted product is stretched in the cylinder axial direction. Thus, there is known a tubular knitted product that is reduced in diameter by plastic deformation in accordance with the outer diameter of a cable to be extrapolated (see Patent Document 2).
Further, as a covering material of a third example, a cover for a wiring cord formed into a cylindrical shape by knit knitting chemical fibers is known (see Patent Document 3).

  Further, as a covering material of the fourth example, after a thin stainless steel wire is knitted into a cylindrical shape, it is wound around a roller and formed into a two-layered strip that is flattened. There is known a gasket formed by rounding again into a cylindrical shape so that both ends in the direction overlap each other (see Patent Document 4). In this gasket, both ends in the longitudinal direction of the strip are overlapped so as to form a spiral around the cylindrical shape.

  The covering materials of the first to third examples described above are all formed as sleeves. That is, the shape is retained as a completed cylindrical shape and does not expand or contract in the radial direction. For this reason, it is very difficult to insert a long material into such a covering material, and there is a problem that it takes work time. In addition, there has been a problem in that the covering material after insertion has circumferential wrinkles, streaks in the tube axis direction, and the like, leading to deterioration in appearance.

Needless to say, the reason why it is difficult to insert the long material into the covering material is that the tip of the long material is caught on the inner surface of the covering material, or the cylinder that occurs between the outer surface of the long material and the inner surface of the covering material. There is an excessive accumulation of axial frictional resistance. In particular, in the coating materials of the first and second examples, the problem is solved when problems such as catching and frictional resistance occur due to the intentional selection of metal wires that are likely to cause plastic deformation. In some cases, the coating material or the long material may be damaged, or the coating material and the long material may be disabled. Further, when both ends of the long material are fixed by wiring or the like, subsequent coating is difficult.

  On the other hand, in the covering material of the above-described fourth example, it is gradually unrolled from one end side in the longitudinal direction and developed (while returning to a flat belt shape), and is covered with a long material in this developed state, and after that, it is again long. An extremely troublesome and skillful work such as regenerating the roundness surrounding the outer peripheral surface of the scale member is required. For this reason, it is still very difficult to attach to a long material, which leads to a problem of requiring work time. In addition, since the roundness imparted to the covering material is not backed up by the elastic force, there is a problem that the covering is released relatively easily after the covering.

  The present invention has been made in view of the above circumstances, and makes it possible to easily and quickly cover and attach a long material such as a cable or a bar, and then, as a covering state on the long material, Metal wire winding that can maintain a good appearance without causing wrinkles in the direction and streak in the cylinder axis direction, and that can provide effects such as reinforcement, soundproofing, and electromagnetic wave countermeasures in the longitudinal direction and for a long period of time. The object is to provide adhesive tape material.

  In addition, the present invention can maintain a good appearance without the occurrence of wrinkles in the circumferential direction and streaks in the cylindrical axis direction as a state covered with a metal wire wrapping tape material, and also has effects such as reinforcement and countermeasures against electromagnetic waves. An object of the present invention is to provide a long material which is uniform in direction and can be obtained over a long period of time.

In order to achieve the above object, the present invention has taken the following measures.
That is, the metal wire wrapping tape material according to the present invention is formed in a band shape by a knitted fabric knitted with a metal wire having an elastic restoring force that maintains a loop shape, and the course proceeds while forming a loop in the knitted fabric. A curling hook is provided to wind at least one side edge along the longitudinal direction of the belt toward the center of the width of the belt by setting the direction along the direction intersecting the longitudinal direction of the belt. .

It is preferable that the knitted fabric has a front and back asymmetric structure, particularly a flat knitted structure.
The knitted fabric is preferably tightly knitted with a stitch of 20 stitches / half inch or more.
In the knitted fabric, the course direction is preferably a direction that is non-perpendicular to the longitudinal direction of the band.
The knitted fabric may have a reinforcing edge formed of an elastic material at at least one side edge along the longitudinal direction of the band.

It is also possible that at least one surface of the front and back surfaces of the knitted fabric is covered with a resin coating layer. The knitted fabric can be knitted by knitting with resin fibers, organic fibers, or the like, or the knitted fabric can be knitted using covering yarn.
A knob formed of a non-conductive material may be provided so as to protrude outward in the band width direction at least at one end in the band longitudinal direction of the knitted fabric.

The metal wire may have a Young's modulus of 18 × 10 ¹⁰ N / m ² or more.
The metal wire may be any one metal such as tungsten, molybdenum, iron, nickel, chromium, tantalum, cobalt, rhodium, ruthenium, an alloy thereof, stainless steel, or the like. By including these metal wires, curl can be expressed in the knitted fabric. Therefore, if this is a condition, the knitted fabric was knitted with other fibers, natural fibers, and resin fibers. The knitting can be done arbitrarily.

  As a method of manufacturing the metal wire winding tape material according to the present invention, a knitted fabric is knitted with a metal wire having an elastic restoring force that maintains a loop shape, and the loop is formed in the knitted fabric. By adopting a method of generating a curl that winds up to the center of the band width with respect to at least one side edge in the band longitudinal direction by cutting so that the direction intersecting the course direction progressing becomes the band longitudinal direction Good.

Among the methods described above, the procedure for cutting the knitted fabric into a band shape may be performed such that the course direction is a non-perpendicular direction to the band longitudinal direction.
On the other hand, the coated long material according to the present invention has a long material as a winding core and a metal wire winding tape material covering the long material, and the metal wire winding tape material is a loop. It is formed in a band shape by a knitted fabric knitted with a metal wire having an elastic restoring force that retains its shape, and the course direction while forming a loop in the knitted fabric is set along the direction intersecting the longitudinal direction of the belt It is characterized by being provided with a curl that winds at least one side edge along the longitudinal direction of the belt toward the center of the width of the belt.

The metal wire wrapping tape material is formed by cutting from a tubular knitted fabric whose circumferential direction is the course direction, and a winding shaft set in parallel with the cylindrical shaft of the tubular knitted fabric. It is preferable that the course direction is arranged so as to intersect the longitudinal direction of the long material by winding along the longitudinal direction of the long material.
Alternatively, the metal wire wrapping tape material is formed by cutting from a tubular knitted fabric whose circumferential direction is the course direction, and is set so as to intersect with a cylindrical axis of the tubular knitted fabric. The course direction may be arranged along the longitudinal direction of the long material by winding the winding shaft along the longitudinal direction of the long material.

  In addition, although the said cylindrical knitted fabric based on the said metal wire winding tape material can be knitted with a circular knitting machine, you may make it knitted with a flat knitting machine.

  The metal wire wrapping tape material according to the present invention can be easily and quickly coated and attached to a long material such as a cable or a bar material. In addition, it is possible to maintain a good appearance without causing streaking or the like in the cylinder axis direction, and to obtain effects such as reinforcement, soundproofing, and electromagnetic wave countermeasures in the longitudinal direction uniformly and over a long period of time.

Note that the metal wire wrapping tape material according to the present invention has flexibility, so even if the long material is bent or the long material is a cable or the like and has movement, There is also an advantage of flexibly following the combined bent shape and movement.
In addition, the coated long material according to the present invention can maintain a good appearance without the occurrence of wrinkles in the circumferential direction, streaks in the cylindrical axis direction, and the like as coated with a metal wire wrapping tape material. In addition, effects such as electromagnetic wave countermeasures can be obtained in the longitudinal direction uniformly and over a long period of time.

FIG. 4 is a photograph showing a curled state when the inclination angle θ is 45 ° in Example 1. FIG. 4 is a photograph showing a curled state when the inclination angle θ is 90 ° in Example 1. FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a main part of a winding tape material 1 according to a first embodiment of the present invention. This winding tape material 1 is made of a metal wire, and is formed into a tubular (hollow tubular) curled shape and a long shape (FIG. 1 is a diagram in which a part in the longitudinal direction is extracted). . And this winding tape material 1 is provided with abundant flexibility, although it is a metal wire, The longitudinal direction can be freely bent.

  The tubular shape of the winding tape material 1 is held by an elastic force that the original shape (so-called tape-shaped main body portion) tries to curl itself. Therefore, this winding tape material 1 is not only before winding (when the winding tape material 1 is present alone), but also after being wound around a long material 2 (see FIG. 5) such as a cable or bar. The tubular shape is maintained. The long material 2 may be a plurality of pieces, and the cross-sectional shape of the tube shape is not limited to a circular shape, and is not limited to an elliptical shape or a triangular rice ball shape.

  Maintaining the tubular shape in this manner is necessary and important for facilitating the operation of winding the winding tape material 1 around the long material 2 and for reliably maintaining the covering state after winding. The Even when the long material 2 (the coated long material 5 according to the present invention to be described later) is frequently bent after being wound around the long material 2, the covering state is elastic. Since it is backed up by force, it does not lead to slack, and it has the effect of ensuring a reliable covering state. In other words, the long covering material 5 according to the present invention has an effect that it can be used without any problem even in an environment in which it is bent frequently.

As is clear from the above description, the winding tape material 1 has its band length in a situation where it is unrolled and developed into a tape shape (= band shape) while resisting the elastic force that holds the tubular shape. It can be said that it is configured by giving a curl so as to be wound around at least one side edge along the direction toward the center of the band width. The method and means for imparting the curl are based on the manufacturing method for forming the original shape with a metal wire and the specific conditions for selecting the metal wire. These will be described below.

  FIG. 2 schematically shows a method for producing the wound tape material 1 (original shape). As is apparent from FIG. 2, the winding tape material 1 is formed based on a tubular knitted fabric 3 knitted by a circular knitting machine or the like. That is, the original form of the wound tape material 1 is a knitted fabric. It is preferable that the knitted structure is a flat knitting (asymmetrical on the front and back sides) in which a loop and a configuration difference occur between the front surface and the back surface.

  The cylindrical knitted fabric 3 knitted by the circular knitting machine is a direction in which the direction of traveling while forming a loop (hereinafter referred to as “course direction”) is perpendicular to the cylinder axis P and parallel to the circumferential direction of the cylinder It becomes. Such a tubular knitted fabric 3 expresses abundant stretchability (easiness of elongation) in the wale direction (direction along the cylinder axis P) perpendicular to the course direction as compared with the course direction. However, since the tubular knitted fabric 3 is selected as a metal wire having an elastic restoring force as will be described later, the contraction force (tightening force to return the elongation) is strong in the course direction. Will appear.

  That is, as shown in FIG. 3 (a), in the needle loop 4a, the portion that sinks between the sinker loops 4b, 4b of the previous course (the upper loop in FIG. 3 (a)) The curling action toward the back of the knitted fabric has occurred as indicated by the arrow X in Fig. 1, and it has been found that the stronger the elastic restoring force of the metal wire used, the stronger the curling action appears. . In this way, the curling action of the needle loop 4a attracts the sinker loops 4b, 4b on both sides, and the course direction is contracted by this attracting force, so the curl toward the back surface of the tubular knitted fabric 3 as shown in FIG. This leads to the generation of (two-dot chain line).

In addition, since a metal wire with elastic restoring force is selected, it is packed tightly (the sum of the number of wales per ½ inch and the number of courses) and dense (the operation to make this dense) By adopting a knitting method (referred to as “degree packing”), the curl is further strengthened (the elastic force is increased or the curl diameter is decreased).
That is, in the present invention, the tubular knitted fabric 3 used for the original form of the winding tape material 1 is selected from those having an elastic restoring force as a metal wire, thereby strengthening the contraction force appearing in the course direction (FIG. 3 and FIG. 4), and further, the shrinkage force is further strengthened by adopting degree filling, so that the so-called “lateral curl” that wraps around the course direction around the wale direction has occurred strongly. It has become a thing.

  Therefore, the tubular knitted fabric 3 (see FIG. 2) is cut so as to have a tape shape (constant width) in an oblique direction with an inclination angle θ that is non-perpendicular and non-parallel to the course direction. The original shape of the wound tape material 1 is taken out. Then, since the original form of the winding tape material 1 obtained by this cutting has a fiber structure in which the course direction intersects with the band longitudinal direction at an inclination angle θ, it intersects with the band longitudinal direction. Elasticity and tightening force act in the state. For this reason, this action causes a curl that winds toward the center of the band width at at least one side edge along the band longitudinal direction.

In addition, when performing flat knitting with a circular knitting machine using chemical fibers or natural fibers for the purpose of knitting clothing, etc., curls (courses) that wind up both ends of the cylinder axis in the first place are knitted on the knitted tubular fabric. A so-called “vertical curl” that winds up the wale direction around the direction tends to occur. If the curl is too strong, it is unsuitable as a product (defective product).
Accordingly, when knitting clothing or the like, secondary processing such as steam set is necessary, and therefore it is common technical knowledge to refrain from filling as much as possible.

According to the present inventor, in the present invention, a metal wire having an elastic restoring force is selected, and further, the filling is also adopted, so that the expression of “lateral curl” is expressed rather than “vertical curl”. Although it is the greatest factor of being superior, I guess that not only that, but also the following may be a factor.
That is, in the case of natural fiber or chemical fiber, circumferential extensible residual stress is generated in the tubular knitted fabric so as to repel the circumferential shrinkage force applied to the tubular knitted fabric when pulled out from the circular knitting machine. . Therefore, assuming that the tape-shaped fabric is cut out from the tubular knitted fabric (residual stress is released), “vertical curl” is easily generated at both side edges of the fabric due to the contraction force in the cylindrical axis direction. I think that. On the other hand, in the case of a metal wire, the tubular knitted fabric 3 is stretchable in the cylinder axial direction because the circumferential shrinkage force of the tubular knitted fabric 3 is not released when it is pulled out from the circular knitting machine. Residual stress occurs. Therefore, when the winding tape material 1 is cut out from the tubular knitted fabric 3, the “lateral curl” caused by the shrinkage force in the circumferential direction is not likely to occur at both side edges of the winding tape material 1. I think.

As described above, the present invention is based on a technical idea that is different from general technical common sense in the case of knitting clothing and the like, and is premised on using a metal wire having an elastic restoring force. In addition, it can be said that the knitting is actively carried out and the knitting is performed.
In addition to pre-packing, a metal wire is tightly wound around a thin cone, etc., and the metal wire is unwound from the outer peripheral surface of the wound cylindrical surface. In some cases, the method of imparting the curl is also useful in strengthening the curl against the wound tape material 1.

In the present invention, the actual degree of packing is determined according to the thickness and type of metal wire, properties such as stretchability and tightening force, the number of yarns to be inserted into the yarn feeder of the circular knitting machine, and chemical fibers. Since it depends on various conditions such as whether or not, it cannot be specified unconditionally.
For example, compared with the case where the metal wire is made of stainless steel and the mesh is 54.5 mesh / half inch and the fabric weight is 207 g / m ² , the mesh is approximately half the size 27.5 mesh / half inch and the fabric weight is 78 g / m ^2. It has been found that the curling action is weakened. From this, it can be said that the same material and the same wire diameter can increase the curling effect as the degree is increased.

The wire diameter of the metal wire is preferably about 10 μm or more and 500 μm. If it is thinner than 10 μm, the strength is insufficient and cutting (thread breakage) may occur, and if it is thicker than 500 μm, the rigidity becomes too high and knitting becomes impossible. In addition, it can be said that it is suitable for the thing with a wire diameter of about 10-50 micrometers to arrange a plurality (2-3 etc.).
The elastic restoring force required as a metal wire selection condition (required characteristic) refers to an action for maintaining a loop shape. Specifically, a material having a Young's modulus (10 ¹⁰ N / m ² ) exceeding 18 is suitable. That is, it is preferable that it is difficult to plastically deform and has a repulsive force. Examples of such materials include any one metal such as tungsten, molybdenum, iron, nickel, chromium, tantalum, cobalt, rhodium, and ruthenium, an alloy thereof, stainless steel, and the like.

Unlike metal wires that are easily plastically deformed, such as copper and aluminum, these metal wires are less likely to be deformed or crushed by the elastic restoring force that holds the loops, and even after the winding tape material 1 is finally formed. The loop shape is reliably maintained, and the entangled state between the loops flexibly follows the movement of the winding tape material 1. However, a predetermined Young's modulus is not required for all metal wires used. That is, since it is only necessary to obtain a large elastic restoring force for the entire knitted fabric, it is also possible to mix and align metal wires having a low Young's modulus if, for example, a plurality of metal wires are aligned.

  The inclination angle θ when the original form of the wound tape material 1 is taken out from the tubular knitted fabric 3 by cutting may be set to 45 °, for example. However, this inclination angle θ is closely linked to the knitting structure, stitches, metal wire type and wire diameter, and so on, and greatly influences the strength of the curl applied to the original shape. In addition, the strength of the curl varies depending on the thickness of the long material 2, the usage environment, the purpose of use, and the like. From these circumstances, the specific numerical value of the inclination angle θ is not particularly limited. In other words, the inclination angle θ may be appropriately determined in relation to other conditions within a range exceeding 0 ° and less than 90 °.

  Note that the smaller the inclination angle θ, the stronger the curl generated in the longitudinal direction of the winding tape material 1 and the more the number of windings tends to increase. It is good to do. However, the smaller the inclination angle θ, the stronger the winding wrinkles from one (one side) side edge of the winding tape material 1, and conversely, the larger the inclination angle θ, the larger the angle from both side edges of the winding tape material 1. Since there is a tendency that the curl becomes stronger, it is preferable to determine the inclination angle θ by comprehensively considering these tendencies.

  The tubular knitted fabric 3 is not limited to a flat knitting. For example, in a circular knitting machine, it is possible to adopt a knitted structure by rubber knitting or smooth knitting and its application structure by knitting the drawing amount, yarn feeding amount, etc. as biased toward the cylinder side or dial side. . In short, various knitting structures can be used as long as the knitting structure causes a loop and a configuration difference on the front and back surfaces of the knitted fabric and causes curling. In this way, curl that is expressed for each knitting structure of the tubular knitted fabric 3 may be used, and as a result, the curl that is expressed may be a vertical curl or a horizontal curl. ,It turns out that.

In addition, we adopt a knitting method in which elastic yarn such as polyurethane is knitted by plating or knitting to the metal wire, or weaving heat-welding yarn (welding yarn) or molten yarn, and then heat setting treatment It is also possible to adopt a method to do.
5 and 6 show the long coated material 5 according to the present invention. The long coated material 5 has a long material 2 as a winding core and a winding tape material 1 covering the long material 2. In order to coat the winding material 1 on the long material 2, the heel is similar to the procedure for wrapping a bandage around a leg, arm, etc., and the winding tape material 1 is long from one band end side. What is necessary is just to make it coat | cover while making it circulate around the scale material 2 helically. However, since it is not limited at all whether it is performed manually or mechanically, the coating method is not particularly limited.

  By the way, when covering the long tape 2 with the winding tape 1, the winding axis Q (see FIGS. 2 and 5) set as a direction approximating parallel or parallel to the cylinder axis P of the tubular knitted fabric 3 is used. It is good to make it run along the longitudinal direction of the long material 2. By performing such winding, the angle α at which the course direction intersects the longitudinal direction of the long material 2 is arranged so as to be substantially orthogonal.

  The side edge portions on both sides in the band width direction of the winding tape material 1 are preferably overlapped (see also FIG. 6). In addition, as shown in FIG. 7, you may perform the winding which piles up many times, or the winding which piles up the several winding tape material 1. FIG. Further, as shown in FIG. 8, a guard layer 7 is provided by extrapolating a covering tube material, winding a vinyl tape or the like, or attaching a resin coat to the outer surface around which the winding tape material 1 is wound. It may be. In the example shown in the figure, there is a circumferential gap between the wound outer surface of the winding tape material 1 and the guard layer 7, but the circumferential gap may be eliminated to allow close contact.

As shown in FIG. 9, it is preferable that the winding tape material 1 is formed with reinforcing edges 8 made of an elastic material at both side edges along the longitudinal direction of the band. By forming the reinforcing edge 8 as described above, effects such as prevention of fraying of the stitch and reinforcement of the side edge of the tape can be obtained. For example, a rubber material such as urethane or silicone may be employed as the elastic material forming the reinforcing edge 8.
Further, as shown in FIG. 10, a resin coating layer 9 may be formed on at least one of the front and back surfaces of the winding tape material 1. Naturally, both sides of the wound tape material 1 may be used, or the entire tape may be impregnated. This resin coating layer 9 can be appropriately formed by a coating method, a laminating method, or the like. It can also be realized by the heat setting method described above.

  As shown in FIG. 11, a knob 10 formed of a non-conductive material may be provided so as to project outward in the band width direction at least at one end in the band longitudinal direction of the winding tape material 1. . By providing such a knob 10, the manual winding of the long material 2 can be performed more easily. The non-conductive material forming the knob 10 is preferably a resin sheet, cloth, paper, or the like.

In the case where the long tape 2 is covered with the winding tape material 1, as shown in FIG. 12, the winding axis R (see FIG. 12) set by intersecting (for example, orthogonal) with the cylindrical axis P of the cylindrical knitted fabric 3 2 may also be set along the longitudinal direction of the long material 2. By performing such winding, the course direction is arranged so as to be substantially parallel to the longitudinal direction of the long material 2.
FIG. 13: is the perspective view which showed the principal part about 2nd Embodiment of the winding tape material 1 which concerns on this invention. The most different place of the winding tape material 1 of the second embodiment from the first embodiment (FIGS. 1 to 5) is that the original form of the winding tape material 1 is a tubular knitted fabric 3 as shown in FIG. From this point, it is cut out in a direction substantially perpendicular to the course direction (that is, the inclination angle θ described in the first embodiment is approximately 90 °).

  For the original form of the wound tape material 1 obtained by such cutting, stretchability and tightening force act in a state intersecting with the longitudinal direction of the band (that is, corresponding to the course direction). Therefore, a curl that winds toward the center of the band width is generated at both side edges along the longitudinal direction of the band. Using this curl, it is wound around the long material 2 as shown in FIG. 15 (it is not a spiral winding but a covering operation to wrap up).

As in the case of the first embodiment, since a specific metal wire is used for the knitting of the tubular knitted fabric 3, the curl is strengthened by performing the filling (elastic force). Or increase the curl diameter). Various embodiments as described with reference to FIGS. 6 to 10 can be similarly employed in the second embodiment.
When the winding tape material 1 of the second embodiment is manufactured, the division schedule line that matches the width of the band so that the longitudinal direction is aligned with the direction of the cylinder axis P at the stage of knitting the tubular knitted fabric 3. Can be created. This scheduled division line can be realized by adopting a method of making a mistake by always operating (or not operating) a specific needle selector in a circular knitting machine, or a method of removing a needle.

16 shows a curled state when the inclination angle θ is 0 ° in Example 1, FIG. 17 shows a curled state when the inclination angle θ is 45 °, and FIG. 18 shows an inclination angle θ. The curl state is shown when the angle is 90 °.

On the other hand, in Examples 4 and 5, although the curl number is smaller than in Examples 1 to 3, the expression of curl is recognized. In particular, when θ is set to 0 °, it can be seen that a curl number (number of windings) exceeding one time is obtained within a length of 20 cm. Therefore, implementation as winding tape material 1 of the present invention is recognized by setting θ in the range of 0 ° to 45 °.
In contrast, in Comparative Examples 1 to 3, almost no curl was observed, and the curl number could not be counted.

By the way, this invention is not limited to the said embodiment, It can change suitably according to embodiment.
For example, the wrapping tape material 1 according to the present invention may be used daily by an individual for the purpose of preventing the adverse effects of electromagnetic waves on a power cord, a communication cable, etc. (long material 2). In addition, a coating process may be incorporated in a production line such as a power cord or a communication cable to make it a product specification.

In addition, the long material 2 may be used for the purpose of reinforcement, heat insulation, sound insulation, etc., using a fluid delivery pipe such as a water pipe, an air conduit, and a gas conduit as the long material 2.
Since the winding tape material 1 is formed of a metal wire, it can be used as a heater by applying a voltage. Therefore, for example, the winding tape material 1 may be covered with the handle of an automobile or a motorcycle as the long material 2.
