To achieve the above, uniformly spaced gaps defined by adjacent ones of outer strands (2) and the outer peripheryof a core rope are formed by spacers, and the gaps are filled with a resin layer (301) integrated with an outer layer resin (300) positioned outside a circle circumscribing the outer strands.
Description
Technical field
The present invention relates to be suitable as the cladded type cable of the moving rope of usefulness such as crane or elevator.
Background technology
Employed moving ropes such as loading mechanization such as crane or elevator are owing to its rope moves via pulley or reels, so be in the length range under working tensions all and the crooked stringent condition.
In the prior art, the rope as this moving rope is used, as defineds such as JISG3525 or 3546, use the rope of following structure: its periphery configuration and twisted at the core rope of making of the twisted wire of fiber or steel, rope has many side twisted wires.
But, according to this structure, on core rope and side twisted wire, can produce high surface pressing, and, the friction that meeting is produced core rope and side twisted wire owing to rope by bendings such as pulleys.Thus, when the core rope weares and teares, when the diameter of rope reduces, the side twisted wire surface pressing each other of adjacency increases gradually.Its result exists each twisted wire to wear and tear, constitute the problem of each monofilament generation broken string of core rope and side twisted wire.
In addition, the side twisted wire often carries out relative the slip with pulley Metal Contact ground, so not only noise is big, also can cause soft relatively pulley to wear and tear usually, and the pulley of changing high price need spend a large amount of labours and time.
In addition, because the generation of rust and the raising of fatigability, in the use of rope, need oiling, because the effect pulley of this oil and the coefficient of friction between the rope reduce, and because the slip between pulley and the rope, the rotation of pulley is difficult to accurately be delivered on the rope, thereby the position control accuracy that is attached at the object on the rope descends.For example in elevator, rotatablely move and the moving up and down of sedan-chair body of pulley can not be linked exactly, thereby are difficult to control the accurate position of sedan-chair body.As its countermeasure, must be implemented in special processing such as undercut portions is set in the groove of pulley or carry out with processing such as dual winding method coiling ropes, its result has produced that equipment cost uprises, the installation of rope and change problems such as very consuming time.
As the solution countermeasure of the wearing and tearing that caused by the contact between the side twisted wire, it is effective at the side twisted wire distance piece being set each other.As its method, the side twisted wire is had a mind to be made for thin diameter, by such side twisted wire is configured to the core rope around, thereby between each side twisted wire, make the space, but when the twisted rope, it is unstable that the position of side twisted wire becomes, and makes the space between each side twisted wire become unequal inevitably.The side twisted wire can take place and be in direct contact with one another and produce wearing and tearing, or cause the problems such as broken string of monofilament in its result.Can not obtain actual effect.In addition, even cladding is set for the metallicity contact that prevents the side twisted wire, the thickness of the resin bed between the side twisted wire also can be unequal, can not prevent that thin part because of resin interlayer from taking place to destroy to wait causes the side twisted wire to be in direct contact with one another thereby wear problems takes place, so be not effective.
As countermeasure, the rope of following structure is arranged: in the space of its each general triangular shape between core rope and side twisted wire, the parts of making to become this shape (triangle) are set, and with the side twisted wire twist with the fingers into.According to the prior art, can prevent contacting between core rope and the side twisted wire, but still can not avoid the wearing and tearing that produce because of the mutual direct contact of side twisted wire.Take place for fear of this problem, need between each side twisted wire, also press from both sides and be set as the shape filling member, but the side twisted wire owing to twisted multifilament become and have complicated concavo-convex cross sectional shape, the filling member that make the cross sectional shape that coincide therewith is very difficult.In addition, when carrying out twisted, make the cross sectional shape of this filling member and side twisted wire be configured also very difficult accurately identically.Therefore, can not avoid the generation in gap and the breakage of filling member, the shaping filling member comes off easily and causes the side twisted wire to be in direct contact with one another in the use of rope.In addition, the circumscribed circle of side twisted wire part often with the relative slip in ground of pulley Metal Contact, so, still can not solve the problem that generation noise, soft pulley wear and tear, spend when changing pulley a large amount of labours and time.In addition, owing to need oiling, so the coefficient of friction between pulley and the rope changes owing to oily, the problem that the rotation of pulley can not be delivered on the rope exactly also still exists.
The present invention makes for addressing the above problem just, its purpose is to provide a kind of cladded type cable, it can prevent core rope and caused wearing and tearing of contacting of outside twisted wire and the caused wearing and tearing of outside twisted wire contact each other reliably, improve fatigue durability, simultaneously, the wearing and tearing that cause with direct contact of outside twisted wire by pulley can be prevented reliably, and good driving force transmission and solemn silence with pulley can be realized simultaneously.
In addition, another object of the present invention is to provide a kind of cladded type cable, it can realize core rope and the contact preventing of side twisted wire and the mutual contact preventing of outside twisted wire of adjacency by simple structure, does not use special twisting machine to make cheaply.
Summary of the invention
For achieving the above object, the essential characteristic of cladded type cable of the present invention is, be to have the core rope, configuration and twisted are at many side twisted wires of this core rope periphery, rope with the resin-coating body that surrounds all aforementioned side twisted wires, the resin-coating layer that the core rigging has core rope main body and this core rope main body is wrapped outward, core rope main body and side twisted wire are isolated by this resin-coating layer, on the external peripheral zone of core rope, has the resinous distance piece in each paddy that is located in the side twisted wire in addition, between each side twisted wire, be formed with the gap of approximate equality by this distance piece, these gaps by with the outermost resin of the circumscribed circle that surpasses the side twisted wire integrated the resin bed landfill get up.
Constitute according to this, the resin-coating layer of the outsourcing core rope main body by the core rope is kept apart core rope main body and side twisted wire substantially, so, can prevent the caused wearing and tearing that contact between core rope and the outside twisted wire.In addition, by between each side twisted wire, form the gap of approximate equality by the resinite distance piece in each paddy that is folded in the side twisted wire, can prevent the contact each other of outside twisted wire, and, above-mentioned gap is by extend into centripetal resin bed landfill with the outermost resin that covers the side twisted wire integratedly, so place, the space of twisted wire can change.In addition, the resin bed that is folded between each side twisted wire works as bolster, so can prevent the wearing and tearing between each side twisted wire fully.Thus, improve fatigue durability, can prolong the life-span of rope.
In addition, owing to the integral coating resin bed that has above the circumscribed circle of side twisted wire, thus can prevent the caused wearing and tearing of Metal Contact of limited slip wheel and outside twisted wire, because the integral coating resin bed is littler than the hardness of pulley, so can prevent the wearing and tearing of limited slip wheel.And, utilize the noise when the integral coating resin bed is feasible to be contacted with pulley to reduce, kept solemnly silent property.Also obtained the coefficient of friction good, can be reliably the power of pulley be delivered on side twisted wire and the core rope with pulley.In addition, because the cross section of rope is rounded, so rotation or torsion effect have also alleviated.Aspect the use of rope,, avoided pollution on every side owing to needn't supply with oil.
In preferred first embodiment of the present invention, distance piece is a plurality of spiral helicine groove on the external peripheral zone of the resin-coating layer that equally spaced is formed on outsourcing core rope main body, each spiral helicine groove has the spacing that equates with the twisted spacing of rope, and has a width that enters with the upside monofilament that can make each side twisted wire, and the spiral helicine groove of each of adjacency is demarcated by the spiral helicine projection of the paddy that is used for being folded in the side twisted wire each other.
According to present embodiment, the mechanism of the resin-coating layer of core rope main body self double as isolated core rope main body and side twisted wire and between each side twisted wire, form the mechanism in impartial gap, so use number of components few, the also available general twisting machine of twisted operation carries out.In addition, the gap length in rope uses between each side twisted wire can not change, and can not cause moving or the abrasion damage of distance piece yet, so, the effect that can keep bolster at the monofilament life period reliably.
In the above-described embodiment, the resin-coating layer of outsourcing core rope main body and spiral helicine groove be by being encased in nozzle on the resin extruded machine, core rope main body being inserted lead in the aforementioned nozzle and the nozzle rotation is made, and described nozzle forms the groove of usefulness uniformly-spaced to have spiral helicine projection.Thus, the make efficiency height of resin-coating layer and distance piece can carry out with low cost.
Preferably, the cladded type cable of first embodiment is made by following operation: use equally spaced is formed with the core rope of a plurality of spiral helicine grooves on the external peripheral zone of the resin-coating layer of outsourcing core rope main body, as distance piece, the mode of each spiral helicine groove disposes and each side twisted wire of twisted so that the side monofilament more than enters into, and is produced on the operation of the naked rope in the gap that is formed with approximate equality between each side twisted wire; Thereby when making naked rope form the resin skin of the circumscribed circle that surpasses the side twisted wire, molten resin is pressed in the gap that is filled between aforementioned each side twisted wire, thereby the operation of formation middle resin layer by extruder.Constitute according to this, can carry out the making of naked rope, in addition, need not apply the resin-coating body that surrounds each side twisted wire, once finish the coating operation with general twisting machine, so, make easily, can make rope with low-cost high-efficiency ground.
Preferred second embodiment of the present invention is, distance piece is made of many resin thread like bodies, and these resin thread like bodies are configured in the periphery of core rope in the mode between each side twisted wire, with side twisted wire twisted together.According to present embodiment, form the gap of approximate equality by each resin thread like body each other at the side twisted wire, between side twisted wire and core rope main body, also form the gap in addition.The resin thread like body is the parts that are independent of the core rope, so how still few the radical of the side twisted wire of the rope that no matter will make is, and can both be corresponding freely.The resin-coating layer of outsourcing core rope main body can be thin thickness, does not need helicla flute in addition, so the making of core rope does not need to coat especially nozzle.The resin thread like body preferably has line feeder at the center, thus, can reliably prevent contacting and the contact each other of side twisted wire between core rope and the side twisted wire under the situation of not losing the steel filling rate in the area of section.
In this second embodiment, above-mentioned resin thread like body, fusion is not integrated energetically with the resin bed of filling with the shape that diverges out from the inboard of integral coating resin bed, but exists with solid forms independently.Constitute according to this, the action of side twisted wire becomes smooth and easy when crooked rope, so, can make amount of deflection good.
In preferred the 3rd embodiment of the present invention, the resin thread like body fusion at least partly in second embodiment becomes the part of resin bed.Thus, the resin thread like body not only works as distance piece, also become the part of middle resin layer, so, got up by the resin landfill in each corner of the side twisted wire of adjacency, thus between each side twisted wire by the complete landfill of resin, and, also filled between side twisted wire and the core rope by resin, integrated with outermost resin.Therefore, can prevent by the caused wearing and tearing of contact between the outside twisted wire that contacts caused wearing and tearing, adjacency between core rope and the outside twisted wire and the caused wearing and tearing of Metal Contact of pulley and outside twisted wire, and, can Keep silence property, and can control and pulley between good coefficient of friction, the power from pulley can be delivered on side twisted wire and the core rope via resin bed reliably.

[first embodiment]
In Fig. 1, mark RP1 represents rope integral body, and it is wrapped the integral coating resin 3 that the mode of stating side twisted wire 2 applies and constitute by single core rope 1, many side twisted wires 2 with interior.
Above-mentioned resin-coating layer 1b has the distance piece that is used for forming each other at the side twisted wire gap integratedly.That is, on the periphery of resin-coating layer 1b, with the radical of side twisted wire 2, be formed with spiral helicine groove 10 with the interval of equalization, the spacing of each spiral groove 10 forms with the twisted spacing of rope and equates.
Each spiral groove 10 has the degree of depth and the width of the outer field monofilament 202 that can put at least one side twisted wire 2.In this example, form the arcuation cross section that to place three monofilament 202.And each adjacent spiral groove 10,10 is demarcated by spiral helicine continuous projection 11, and each projection 11 has the height that can extend as shown in Figure 4 in the paddy of each side twisted wire 2, and the projection top is a flat condition.
Use many (in the accompanying drawing being eight) side twisted wires 2.The structure of each side twisted wire 2 is arbitrarily, but in this example, by 8 * S (19), in other words 8 * S (1+9+9) structure constitutes.That is, become following form: configuration and nine thin relatively monofilament 203 of twisted around core monofilament 201 and form internal layer 2a, configuration and nine side monofilament 202 that diameter is thick comparatively speaking of twisted around it.
Each side twisted wire 2, along each spiral groove 10 of resin-coating layer 1b, twisted together under this state.This state as shown in Figure 4, each side twisted wire 2, it is as on outer field three side monofilament contact is at the bottom of being the spiral groove of circular arc, keep thus with being stabilized, between each such side twisted wire 2, be folded with the spiral helicine projection 11 of impartial arranged spaced, so, between the side twisted wire, guaranteed the gap S1 of equal-sized.
Above-mentioned each monofilament uses the steel monofilament.The steel monofilament when requiring rope to have high strength, uses to have TENSILE STRENGTH and be 240kg/cm
2The steel monofilament of above characteristic.This steel monofilament is by being that wire raw material wire rods more than the 0.70wt% carries out wire drawing and obtains to carbon content.Monofilament comprises and has for example monofilament of zinc plating layer, allumen plating layer etc. of thin corrosion resistance clad.Can select monofilament diameter in case can with undertaken by pulley that alternating bending produced was tired corresponding.
Each resin bed 301 forms as one with outer 300, extends into entad shape with the shape from outer 300 forks between side twisted wire 2, up to the projection 11 that arrives resin-coating layer 1b.
Here, resin as skin coating 3, can be polyethylene, polypropylene etc., but be preferably following thermoplastic: it is except mar proof, weather fastness, flexibility (proof stress disruptiveness), also have and be used to realize the suitable elasticity adjusted with the coefficient of friction of pulley, coefficient of friction is higher, can not add water decomposition.As its example, propylene class, polyurethanes for example ethers polyurethane or its elastomer etc. have been enumerated.
On the other hand, the resin of the synthetic resin layer 4b of core rope 1 can use the copolymer etc. of polyvinyl chloride, nylon, polyester, polyethylene, polypropylene and these resins and the good material of cementability of core rope main body 1a.But as rope integral body, inner resin is physics, chemical characteristic homogeneity or better approximate, so synthetic resin layer 4b is preferably particularly identical or approximate with integral coating resin 3 material of thermoplastic resin.When using the resin different, be preferably the material good with the cementability of integral coating resin 3 with integral coating resin 3.
Method to the rope of making first embodiment describes, and makes core rope main body 1a continuously by the resin extruded machine, produces the core rope 1 with band spiral fluted resin-coating layer 1b.
Fig. 5-A to Fig. 5-C shows this operation, on the end of the extruder 9 of spiral grade, is incorporated with the rotary body 92 of the special nozzle 91 of having packed into.Nozzle 91 has through hole, this through hole upwards alternately be provided with repeatedly in week be used for grooving 10, to mould portion 911 that internal diameter direction protrudes and the projection 11 that is used to be shaped to the recessed mould portion 910 of external diameter direction.This nozzle 91 is packed in the rotary body 92 that has gear on periphery in the mode that can not rotate.Rotary body 92 is rotated around axis by 93 extruding of driving bodies such as turbine apparatus.And, driving body 93 with the towing capstan 12 in downstream synchronously the modes of rotation be loaded in the drive system 14, the rotation of rotary body 92 and core rope 1 draw speed synchronization.
Therefore, core rope main body 1a inserted lead in the nozzle 91 of extruder 9, drive towing capstan 12 and it is drawn, if it is batched on coiling machine 13 and with resin 30 pressurizations of 9 pairs of heating and meltings of extruder, then, around core rope main body 1a, be formed on the resin-coating layer 1b that outside diameter has groove and projection by the mould portion 911,910 of nozzle 91.And the driving body 93 of the power by transmitting tractive capstan winch 12 rotates rotary body 92 and nozzle incorporate with it 91, so groove and projection become the helical form that does not have seam.
Then, as shown in Figure 6, send above-mentioned core rope 1 with band spiral fluted resin-coating layer 1b, and, to send side twisted wire 2, and pass end plate 6 its importing twisted device (ボ イ ス) 7, twisted becomes rope.
End plate 6 has the hole 60 of inserting logical core rope 1 at the center, 60 periphery is uniformly-spaced to have the hole 62 of inserting logical side twisted wire 2 in the hole.Cross lay attaches together and puts 7 if rotation end plate 6 and the above-mentioned core rope 1 in river and side twisted wire 2 pass this end plate 6, then each side twisted wire 2,2 fitly is configured in respectively with each spiral groove 10 on the periphery that uniformly-spaced is arranged in resin-coating layer 1b, is keeping this state and is carrying out twisted.Thus, become the such naked rope A of Fig. 4.Preferably, the twisted direction of side twisted wire is opposite with the twisted direction of rope, for example, when the twisted direction with the side twisted wire is made as the S direction, the twisted direction of rope is made as the Z direction.
In this naked rope A, because core rope 1 has resin-coated layer 1b, so the diameter of core rope 1 has correspondingly increased, thereby between side twisted wire 2, form the gap easily, and, utilize the effect of spiral helicine groove 10 and projection 11, between each side twisted wire 2,2, can form impartial gap S 1 exactly.Simultaneously, separate by resin-coating layer 1b in fact between side twisted wire 2 and the core rope 1.
After naked rope A is cleaned by not shown cleaning machine under the state that temporarily batches or do not batch, pass in the mould 90 of extruder 9 of resin 30 of pressurization extrusion molten, carry out continuous integral coating.When this coats extruding, if the ethers polyurethane of Shore D scale 90 for example then is pressed into about 180～200 ℃ molten resin 30 from full week of naked rope A and is filled into the gap S1 impartial between each side twisted wire 2,2.Thus, between side twisted wire 2,2, form impartial resin bed 301.
Side twisted wire 2 is concavo-convex bigger complex cross-sectional shape, and molten resin 30 fills up this shape, finally covers whole side twisted wires 2.Therefore, cylindraceous outer 300 the inside part of making in the mode of surrounding side twisted wire 2 and the bonding force height of side twisted wire 2 are big with respect to the resistance of the changing of the relative positions.
And, to separate by each resin bed 301 fully between the above-mentioned side twisted wire 2,2, the intrusion front end of each resin bed 301 arrives the projection 11 of resin-coating layer 1b.And, since finally by mould 90 from radial direction compression, so, between the side twisted wire 2,2 of adjacency, between side twisted wire 2 and the core rope 1 by the resin landfill.
When the resin of core rope 1 and outer 3 resin are identical or approximate material because physics, the chemical property homogeneous of the resin in the cross section, so cladding be difficult for the effect of the frictional force of pulley or shearing force under break or the changing of the relative positions.
The projection 11 of each resin bed 301 and resin-coating layer 1b becomes at least closely relation of contact.If molten resin 30 is big with the temperature difference of resin-coated layer 1b when coating, each resin bed 301 and resin-coating layer 1b are difficult to integrated, and temperature difference is little, then takes place bonding or welding.Requiring resin bed 301 and resin-coating layer 1b to try one's best when integrated, preferably, as shown in Figure 6, heater 8 is set on production line, for example if use resin to be ethers polyurethane, then be preheating to naked rope A below 150 ℃, 60～120 ℃ of front and back for example.
This first embodiment does not need in advance each side twisted wire 2 to be carried out the operation of resin-coating, carries out the coating of side twisted wire when the integral coating of rope, so the productivity ratio height can make with low cost.If do not adopt structure of the present invention, offside twisted wire 2 carries out resin-coating in advance respectively, then with its with by resin-coating core rope twisted, implement resin-coating in its periphery again, then between coated sides twisted wire cylindraceous and core rope, be easy to generate the space because of resin can not be impregnated into, might damage the integrated of side twisted wire and core rope, but the present invention solved this problem.In addition, owing to can improve the steel filling rate, so can also obtain good line strength.
The rope production process can adopt various schemes.That is, also can the resin-coating layer 1b of core rope 1 not under the state of completely crued stickness offside twisted wire 2 carry out twisted.That is, also can a row formula ground continuously with the making of resin-coated core rope 1, the making and the integral coating of naked rope.Replace, also can be discontinuously with the making of resin-coated core rope 1 and the making of naked rope, and carry out integral coating sending the naked rope that has temporarily batched thereafter.
Fig. 7 to Figure 10 shows other examples of first embodiment.The rope of present embodiment is represented integral body with mark RP11.Basic structure is same as described above, so only difference is described, core rope main body 1a is for configuration and twisted around center monofilament 101 have 1 * 7 structure of six roots of sensation side monofilament 102.In addition, side twisted wire 2 has used the six roots of sensation, and configuration and twisted are around above-mentioned core rope 1.In this example, the side twisted wire has 1 * 7 structure of the monofilament 202 that six roots of sensation side uses to constitute by configuration and twisted around the monofilament 201 at center.
The spiral helicine groove 10 of resin-coating layer periphery be the six roots of sensation with the quantity of spiral helicine projection 11 thereupon, and each spiral helicine groove 10 is for falling trapezoidal cross section, have the width of the side usefulness monofilament 202 that can embed one or two side twisted wire 2.Certainly can be the groove in arcuation cross section in the same manner also with the basic embodiment situation.Other formations are quoted and above-mentioned explanation, and same section marks with identical mark.
[second embodiment]
In Figure 11, mark RP2 represents rope integral body, by single core rope 1, many side twisted wires 2, wrap the integral coating resin 3 that the mode of stating side twisted wire 2 applies and constitute with the distance piece 4 of its equal number with interior.
Above-mentioned core rope 1, with first embodiment in the same manner, by core rope main body 1a with the resin-coating layer 1b of its encirclement constituted, but originally do not form on one's body as the spiral helicine groove of distance piece and the projection of wire at resin-coating layer 1b.The structure of core rope main body 1a can be selected arbitrarily.Side twisted wire 2 is the six roots of sensation in this example, and structure can be selected arbitrarily.
Second embodiment is characterised in that, use the resin thread like body as distance piece 4, it is configured between the paddy and core rope 1 of each side twisted wire 2,2, carry out twisted with each twisted wire 2,2, before coating, as shown in figure 13, each side twisted wire 2,2 is separated equably by resin thread like body 4, forms gap S1 each other at side twisted wire 2,2.
Side twisted wire 2, though under the state of the naked rope A of Figure 13, and have suitable gap between the resin-coating layer 1b, but in the rope of having finished, by the stretching of the length direction in the manufacturing process, as shown in figure 14, contact with resin-coating layer 1b near the rope center.Resin thread like body 4 is because the compressing that above-mentioned action caused of side twisted wire 2 and transmission by the heat that produces with contacting of the molten resin that should form resin bed can produce some distortion, thereby be close at least with resin-coating layer 1b.
Above-mentioned resin thread like body 4, its diameter is chosen to be, and can form to make molten resin fully be pressed into gap between the side twisted wire 2,2.This diameter changes according to radical of side twisted wire etc., under the situation that is six roots of sensation twisted wire, is preferably about 1/6～1/2 of twisted wire diameter usually.Resin thread like body 4 before molten resin is pressed into during in work as distance piece, as long as have above-mentioned functions when molten resin is bulged-in, its shape can change, so cross sectional shape can be direction-free simple toroidal.
Resin thread like body 4 can be thermoplastic resin bar-shaped or the twisted wire by integral body, but in order when carrying out twisted, to guarantee appropriate rigidity with side twisted wire 2,2, and in order when rope is finished, intensity to be produced booster action, shown in Figure 12-A and Figure 12-B, preferably, synthetic resin layer 4b is set around it at center configuration line feeder 4a.Synthetic resin layer 4b is to make in the resin bath of line feeder 4a by fusion to adhere to, and adjusts adhesion amount by carrying out throttling in outlet, or makes in its mould that passes through extruder, obtains serially.
Above-mentioned line feeder 4a can be one like that shown in Figure 12-A, also can be shown in Figure 12-B many 400 of twisteds like that.Usually use the steel monofilament identical as material, also can be other metals such as copper, also can be synthetic fiber with the monofilament of above-mentioned core rope main body or side twisted wire.As synthetic fiber, be preferably the low ductility fiber of the high strength of from aromatic polyamide, ultra-high molecular weight polyethylene, Wholly aromatic polyester etc., selecting.Line feeder is made as described below: form bundle by gathering the many yarns that are made of this fiber, this is restrainted doubling abreast or the lay pitch twisted to grow again, thereby make.
The resin of synthetic resin layer 4b, when using the resin different with the resin of core rope clad 1b and integral coating resin 3, consider mar proof etc., can from the copolymer of polyvinyl chloride, nylon, polyester, polyethylene, polypropylene and these resins etc., select, but from resin and this point of compatibility of integral coating resin 3 and the homogeneous viewpoint of internal resin characteristic of core rope clad 1b, be preferably and have and the resin of core rope clad 1b and the thermoplastic resin of integral coating resin 3 homogeneities or approximate characteristic.Specifically, identical with first embodiment, use with polyurethanes, for example ethers polyurethane etc. to have mar proof, weather fastness, flexibility (proof stress disruptiveness), a suitable flexible resin as representative.
For obtaining the rope of second embodiment, make core rope main body 1a by extruder, produce the core rope 1 of tape tree fat clad 1b.In addition, make and need the side of radical twisted wire 2.On the other hand, therewith dividually, make the resin thread like body 4 that needs radical.
Then, as shown in figure 15, send above-mentioned core rope 1, and send resin thread like body 4 and side twisted wire 2, pass end plate 6 and import twisted device 7, carry out twisted.End plate 6, have the hole 60 of inserting logical core rope 1 at the center, 60 periphery equally spaced has the hole 61 of inserting logical resin thread like body 4 in the hole, on the periphery more outer than hole 61, be positioned at the mode of centre in the hole 61,61 of resin thread like body 4 with the position on the circumference, have the hole 62 of inserting logical side twisted wire 2.
If rotation end plate 6 also passes above-mentioned core rope 1, resin thread like body 4 and side twisted wire 2 and imports twisted device 7, then resin thread like body 4 is twisted with the fingers to go between each side twisted wire 2,2, and equally spaced be configured in the periphery of core rope 1, become naked rope A shown in Figure 13.The twisted direction of side twisted wire is opposite with the twisted direction of rope preferably, for example, when the twisted direction with the side twisted wire is made as the S direction, the twisted direction of rope is made as the Z direction.
In this naked rope A, equally spaced dispose spiral helicine resin thread like body 4 in the periphery of core rope 1, between each side twisted wire 2,2, be formed with impartial gap S1.At this moment, also can utilize resin thread like body 4 between side twisted wire 2 and core rope 1, to form suitable gap S2.
Naked rope A is cleaned by not shown cleaning machine under by the state that temporarily batches or do not batched, and as shown in figure 15, makes in its mould 90 by the extruder 9 of the resin 30 of the extrusion molten that pressurizes, and carries out continuous integral coating.When the temperature that is had at naked rope A is low, preferably carry out preheating by 8 couples of naked rope A of heater, so that being pressed into of molten resin, flowing and suitably carry out, but be not to make 4 fusions of resin thread like body, so do not need the preheating under the high-temperature, the temperature in the time of can be than first embodiment is low.
When this coated extruding, molten resin 30 was by from being pressed into the gap S1 impartial between each side twisted wire 2,2 of naked rope A in full week, also was pressed on the surface of each monofilament that constitutes side twisted wire 2 and in the paddy between the monofilament.
Each resin thread like body 4 is by being heated with the contacting of molten resin 30 of high temperature, and each the side twisted wire 2,2 that produces in the traction of the rope in downstream is oppressed under the effect of moving of rope center position, and the resin-coated layer 1b so can how much deform with core rope 1 is close to.And each side twisted wire 2,2 contacts with the resin-coated layer 1b of core rope 1.
Thus, as shown in figure 14, separated by equal equal thickness and resin bed at interval 301 between the side twisted wire 2,2, side twisted wire 2 is all equally spaced separated by the resin-coated layer 1b of ring-type with core rope main body 1a.Side twisted wire 2 is concavo-convex bigger complex cross-sectional shape, and molten resin 30 fills up this shape and the whole side twisted wire 2 of final covering.
