Description

  The present invention is a wire having no thorns in which the end side of a wire rope is bent into a ring shape and the free end of the bent end is connected and fixed to the wire rope to form a loop-shaped ball hook at the tip of the wire rope. The present invention relates to a method for manufacturing a rope sled rope and a sled rope for a wire rope without thorns.

  2. Description of the Related Art Conventionally, a metal wire rope is configured such that a plurality of strands of strands, which are strands formed by twisting several metal strands, are twisted to form a rope.

  In order to engage the wire rope with the protrusion, a ring-shaped loop portion is formed at the tip of the wire rope, and the loop portion is engaged with the protrusion.

  Therefore, such a loop portion is often used at the tip of the metal wire rope, and this loop shape is called a sling rope.

  Thus, as a method of forming the sled rope of the loop portion, first, for each bundle of strands formed by twisting the free end of the bent wire rope for each bundle of strands, that is, by twisting several metal strands Dissolve in pieces.

  Next, at the position that should be the base end of the loop of the wire rope, a gap between the bundle strands twisted with a needle member called a sharp spiky is opened, and the first strand of the previously separated strands is inserted. Insert through the gap.

  In this way, each separated bundle strand is passed through the different gaps of the twisted strand in the same way, and finally the free ends of all the separated strands are connected to the loop base end of the wire rope. The strand gap formed at the position to be inserted is inserted. Repeating this several times is called a rounding operation.

  After such a rounding operation is performed, the end of each bundle strand protruding through the gap is further branched into two sets of fine bundles, and the first set of fine bundle strands has a desired length from the surface of the wire rope. While cutting, other sets of fine strands that are not cut pass through different strand gaps. Repeating this several times is called half-insertion work.

  In this way, several strand insertion operations are completed and the free end protruding from the gap is cut, whereby the continuous fixing operation of the loop base end of the wire rope is completed, and a loop-shaped slinging cable is completed.

  That is, the wire rope used for the production of a conventional hand-knotted ball rope is made by arranging six pairs of strands in a hexagonal shape around the heart rope and its surroundings, and twisting them in a spiral shape. Is composed of a bundle of a plurality of wire strands constituting the inner side.

  In general, when manufacturing hand-knotted ropes using wire rope, the so-called eye processing that loops the tip of the wire rope into a loop shape follows the standards stipulated by laws and regulations, for example, basket insertion and winding It is made using a specific weaving method called.

  Each twisted strand that is twisted at the base side where the distal end portion is folded, that is, the position that should be the base end of the loop portion, is divided into six bundle strands and core ropes that constitute the wire rope on the folded distal end side The tips of the bundle strands are separated from each other in a predetermined order and are extracted from the determined interval.

  At the base end of the loop part, pass through the ends of the 6 strands of bundled bundles drawn from the main surface of the wire rope in the order determined by the type of weaving method. Repeat at least 3 times to extract from the space.

  After repeating three or more times, the tip side of each of the six separate strands coming out from the surface of the main line is further identified for each set as a fine bundle strand of the outer layer wire and a fine bundle strand of the inner layer wire. Then, it is subdivided into two sets to form 12 sets of free bundle strand free ends, and only the 6 sets of inner layer wire fine bundle strands coming out from the surface of the wire rope are positioned on the surface of the wire rope. Disconnect with.

  Further, the six bundles of the outer layer wires that were not cut are passed in between the specific strands of the strands of the wire rope that are twisted in the order determined by the type of the knitting method. Repeat the work of extracting from a specific interval at least twice (this is called "half-insertion work"). Thereafter, the six bundles of outer layer wires extending out from the surface of the wire rope are cut at the surface position of the wire rope.

  In addition, these work procedures to determine from which space each bundle strand or fine bundle strand of each outer layer wire is passed and from which other space are extracted are determined by the type of knitting method. Further, the surface of the wire rope is lightly leveled with a hammer during each step.

  Conventionally, hand-knitted ball ropes have been made using such a method using a wire rope.

JP 2006-69756 A

  However, in the conventional general slinging line formation work, each inner layer wire and the thin bundle strand of each outer layer wire cut at the surface position of the wire rope are a collection of wire strands having a plurality of strengths. The so-called thorns at the cut portion are sharp, and if the hand comes into direct contact with the thorns, the surface of the hand is cut, which is very dangerous. In addition, there are 6 thorns on the inner layer line of 6 fine bundles and 6 outer layer lines on the 6 fine bundles, and the twelve tangles in total are 12 wire ropes by the 12 fine bundle strands branched. Therefore, it was dangerous to wear gloves when grasping the base end surface of the loop portion of the wire rope.

  In addition, in conventional hand-knitted ball hanging ropes, the inner layer wire and outer layer wire bundles are initially cut at the very end of the surface of the main line, but the main line part where the thorns are dispersed may be bent many times. In the meantime, the thorns gradually protruded from the surface of the main line, and the protruding thorns were very dangerous because they sometimes split their gloves and cut their hands.

  In this way, the biggest problem with the sling rope is that the free ends of a plurality of separated strands are inserted through the gap between the twisted strands formed by spiking and the leading end is cut, so that the cut portion protrudes from the peripheral surface of the wire rope. There is a danger that the tip of the cutting part of the unwinding strand becomes sharp during work and there is a danger that the worker may be injured during the work, and further, the free end of the strand of the strand protrudes from the loop base end of the finally completed sling rope Therefore, it is that it was very dangerous for the user who uses the sling rope of the wire rope.

  For example, Patent Document 1 describes a method for treating an ice price end portion in which the protruding free end of the strand does not protrude from the peripheral surface of the wire rope.

  The processing method of the ice price end portion described in Patent Document 1 is pushed into the core gap formed at the center of the wire rope so that the cutting tip of the bundle strand, the so-called thorn, does not protrude from the peripheral surface of the wire rope. Although the technology has been disclosed, there is a possibility that the thorns gradually pushed in during use of the wire rope sling rope may protrude from between the twisted strands to the peripheral surface of the wire rope.

  Therefore, the inventor of the present application prevents the end of the strand finally inserted into the loop base end of the sling rope from gradually protruding from the surface during use of the wire rope, thereby ensuring the safety of the user of the wire rope. Developed a method for producing wire ropes without wire rope.

  The invention described in claim 12 is a wire rope slinging wire without barbs manufactured by the method for manufacturing a slingless wire rope slinging method according to any one of claims 1-11.

According to the first aspect of the present invention, when a bundle strand or a thin bundle strand is inserted between twisted strands at the loop base end portion of the wire rope, first, twisting in the same direction as the twisting of the wire rope or in the opposite direction is performed. The bundle strand is knitted by inserting between the strand strands along the knitting, this operation is performed several times, and then the bundle strand is knitted along the same direction as the twist of the wire rope or in the opposite direction, respectively. The second fine bundle, which is separated into two sets of fine bundles and separated into the first fine bundle and the second fine bundle, is inserted and knitted between twisted strands in the same direction as the wire rope twist or in the opposite direction. It is going.
Therefore, the twist direction of the wire rope for storing the cutting tip portion of the bundle strand and the cutting tip portion of the thin bundle strand pushed into the core region of the wire rope by weaving the bundle strand or the fine bundle strand; A bundle strand or a thin bundle strand is knitted in a cage insertion state intersecting in the opposite direction or a winding state wound in the same direction to form a knitted storage portion.
That is, the strand cutting tip is formed by a braided storage section in which the bundle strands and fine bundle strands crossed in a mesh form and / or the bundle strands and fine bundle strands wound spirally surround the core region. There is an effect that it can be sealed so that the thorns are wrapped so as not to protrude outside the wire rope.
When tensile stress or bending stress is applied during use as a wire rope sling rope, the crossed bundle strands and fine bundle strands are reduced, and the larger the tensile stress and bending stress, the closer the mesh becomes. By reducing the bundle strands and / or fine bundle strands that are spirally wound and / or spirally wound, the larger the tensile and bending stresses, the tighter the spirally wound eyes are, and there are no gaps. Since the circumferential side wall forms a so-called knitted storage portion, the bundle strand cutting tip and the bundle bundle cutting tip bundled in two or three sets in the gap in the core region of the knitting storage portion There is an effect that the thorns can be completely sealed so that the thorns are contained so that they cannot protrude outside the wire rope.
Further, if two or three pairs of thin bundle strand cutting tips are bundled, the diameter of the bundle strand becomes substantially the same as that of the bundle strand, and there is an effect that it becomes impossible to protrude from the gap in the core region to the outside of the wire rope. Also, by bundling as described above, two or three sets of fine bundle strand cutting tips are integrated so that they do not come apart, so that the fine bundle strand cutting tips are around the core region. It has the effect of making a single line from the stitches and not protruding again.
Then, the cut core wire once drawn to the outside is returned to the gap in the core area to eliminate the gap, and the direction of the thorn which is the cutting end of the thin bundle strand bundled in two or three sets is set to the longitudinal direction of the wire rope. It has the effect of preventing the wire rope from protruding to the outside.

According to the second aspect of the present invention, when the bundle strand is inserted between the twist strands at the loop base end portion of the wire rope, first, in the first weaving step, the wire rope is twisted in the opposite direction. The bundle strands are knitted by being inserted between the stranded strands along the twist, and this operation is performed several times.Then, in the second knitting process, the bundle strands are knitted along the same direction as the wire rope twist, In the third half-insertion knitting process, six sets of fine bundle strands made of the second fine bundle are knitted in the same direction as the wire rope twist.
Therefore, the wire rope for storing the cutting tip of the bundle strand or the cutting tip of the thin bundle strand pushed into the core region of the wire rope by weaving the bundle strand or the fine bundle strand of the second fine bundle The bundle strands are knitted to form a knitted storage portion in the cage insertion state crossing the direction opposite to the twisting direction and the winding state wound in the same direction, and the fine bundle strands are further knitted in the winding state. A knitted storage portion is formed.
That is, the strand cutting tip portion and the bundle strand intersecting in a mesh form, the bundle strand wound spirally, and the thin bundle strand wound spirally surround the periphery of the core region. There is an effect that it is possible to wrap the thorn which is the tip of the thin bundle strand cutting and seal it so as not to protrude to the outside of the wire rope.
And, when tensile stress and bending stress are applied when using it as a wire rope sling, the crossed bundle strands are reduced and the mesh becomes tighter and smaller as the tensile stress and bending stress are larger, Furthermore, by reducing the bundle strands and the thin bundle strands wound spirally, the larger the tensile stress and bending stress, the tighter the spirally wound eyes become, and the circumferential side walls without gaps. Since the so-called knitted storage portion is formed, the bundle strand cutting tip and the thorn which is the bundle strand cutting tip bundled in two or three sets are enclosed in the gap in the core region of the knitting storage portion. There is an effect that it can be completely sealed so as not to protrude outside the wire rope.

According to the third aspect of the present invention, when the bundle strand is inserted between the twisted strands at the loop base end portion of the wire rope, first, in the first weaving step, the twist in the direction opposite to the twist of the wire rope is performed. The bundle strands are knitted by inserting the strands between the strands, and performing this operation a plurality of times.Then, in the second knitting step, the bundle strands are knitted along the direction opposite to the twist of the wire rope, In the third half-insertion knitting step, six sets of fine bundle strands made of the second fine bundle are knitted in the same direction as the twist direction of the wire rope.
Therefore, the cutting tip of the bundle strand pushed into the core region of the wire rope and the cutting tip of the second bundle of fine bundle strands are stored by weaving the bundle strand or the fine bundle strand of the second fine bundle. For this reason, the bundle strands are knitted in a caged state in which the wire rope is twisted in the same direction as the direction of the twisted strands in a cage state crossing the direction opposite to the twisting direction of the wire rope to form a knitted storage portion Will do.
That is, a bundle strand crossed in a mesh shape and a thin bundle strand wound spirally encloses the thorn which is the tip of the strand cut by the braided storage portion surrounding the periphery of the core region, and outside the wire rope. There exists an effect which can be sealed so that it cannot protrude.
When tensile stress or bending stress is applied during use as a wire rope sling rope, the bundle strands crossed in a mesh form and the thin bundle strands wound spirally are reduced, so that tensile stress and bending stress are reduced. The larger the mesh, the tighter the meshes and spirally wound meshes, and the formation of a so-called knitted storage portion with a circumferential side wall without a gap. There is an effect that the bundle strand cutting tip portion and the thorn which is the bundle strand cutting tip portion bundled in two or three sets can be contained and completely sealed so as not to protrude outside the wire rope.

According to the invention described in claim 4, in inserting the bundle strand between the twisted strands at the loop base end portion of the wire rope, first, in the first weaving step, the twist in the same direction as the twist of the wire rope is performed. The bundle strands are twisted along the knitted strands and knitted, and this operation is performed a plurality of times. Then, in the second knitting step, the bundle strands are knitted along the same direction as the wire rope twist. In the half-insertion knitting step, six sets of fine bundle strands composed of the second fine bundle are knitted between the twisted strands of the wire rope along the direction opposite to the twist direction of the wire rope.
Therefore, the twist direction of the wire rope for storing the cutting tip portion of the bundle strand and the cutting tip portion of the thin bundle strand pushed into the core region of the wire rope by weaving the bundle strand and the fine bundle strand; Bundle strands are knitted in the winding state wound in the same direction to form a knitted storage portion, and further, narrow bundle strands are knitted in a basket insertion state crossing in the opposite direction to form a knitted storage portion. become.
That is, the strand cutting tip or the strand cutting tip is cut by the braided storage portion in which the bundle strand wound spirally and the fine bundle strand intersecting in a mesh shape surround the periphery of the core region. There is an effect that it can be sealed so as not to wrap and protrude outside the wire rope.
And when tensile stress or bending stress is applied at the time of use as a wire rope sling rope, the bundle strand wound spirally and the fine bundle strand intersecting the mesh shape are reduced, so that the tensile stress and bending stress are larger. Since the spirally wound meshes and meshes become tighter and smaller, a circumferential side wall without a gap is formed, so-called a knitted storage portion, so that a bundle strand is formed in the gap in the core region of the knitted storage portion. There is an effect that the cutting tip portion and the thorn which is the cutting end portion of the thin bundle strand bundled in two or three sets can be contained and completely sealed so as not to protrude outside the wire rope.

According to the invention described in claim 5, when the bundle strand is inserted between the twisted strands at the loop base end portion of the wire rope, first, in the first weaving step, the twist in the same direction as the wire rope twist is performed. The bundle strands are twisted along the strands and knitted between the strands. This operation is performed a plurality of times, and then in the second weaving step, the bundle strands are knitted along the direction opposite to the twist of the wire rope. In the three-half-insertion knitting step, six sets of fine bundle strands comprising the second fine bundle are knitted in the same direction as the wire rope twist.
Therefore, the wire rope for storing the cutting tip of the bundle strand or the cutting tip of the thin bundle strand pushed into the core region of the wire rope by weaving the bundle strand or the fine bundle strand of the second fine bundle Bundle strands are knitted in a state wound in the same direction as the twisting direction and crossed in the opposite direction to form a knitted storage portion, and further, a thin bundle strand is knitted in a wound state to form a knitted storage portion. Will form.
That is, the cutting tip of the strand is cut by the braided storage section in which the bundle strand wound spirally, the bundle strand intersecting in a mesh shape, and the fine bundle strand wound spirally surround the periphery of the core region. In addition, there is an effect that it is possible to wrap the thorn which is the cutting tip of the thin bundle strand and seal it so as not to protrude outside the wire rope.
When tensile stress or bending stress is applied during use as a wire rope sled rope, the helically wound bundle strands and fine bundle strands are also reduced, so that the higher the tensile stress and bending stress, the more spirally wound. As the tensile strands and bending stresses increase, the meshes become tighter and smaller, and the circumferential side walls without gaps are reduced. Since the so-called knitted storage portion is formed, the bundle strand cutting tip and the thorn which is the cutting tip of the thin bundle bundle bundled in two or three sets are contained in the gap in the core region of the knitting storage portion. Thus, it is possible to completely enclose the wire rope so that it cannot protrude to the outside.

According to the invention described in claim 6, when the bundle strand is inserted between the twisted strands at the loop base end portion of the wire rope, first, in the first weaving step, the wire rope is twisted in the opposite direction. The bundle strands are knitted by being inserted between the stranded strands along the twist, and this operation is performed several times.Then, in the second knitting process, the bundle strands are knitted along the same direction as the wire rope twist, In the third half-insertion knitting step, six sets of fine bundle strands made of the second fine bundle are knitted along the direction opposite to the twist of the wire rope.
Therefore, the wire rope for storing the cutting tip of the bundle strand or the cutting tip of the thin bundle strand pushed into the core region of the wire rope by weaving the bundle strand or the fine bundle strand of the second fine bundle Bundle strands are knitted to form a knitted storage state in a cage insertion state crossing the direction opposite to the direction of twisting and a winding state wound in the same direction, and further, a thin bundle strand is knitted in the cage insertion state. A knitted storage portion is formed.
That is, a strand cutting tip is formed by a braided storage section in which a bundle strand crossed in a mesh shape, a bundle strand wound in a spiral shape, and a fine bundle strand crossed in a mesh shape surround the periphery of the core region. In addition, there is an effect that it is possible to wrap the thorn which is the tip part of the thin bundle strand and to prevent it from protruding outside the wire rope.
When tensile stress or bending stress is applied during use as a wire rope sling rope, the crossed bundle strands and fine bundle strands are reduced, and the larger the tensile stress and bending stress, the closer the mesh becomes. In addition, the bundle strands wound spirally are also reduced, that is, the larger the tensile stress and bending stress, the tighter the spirally wound eyes become, and the circumferential side walls without gaps become smaller. Since the so-called knitted storage portion is formed, the bundle strand cutting tip and the thorn which is the bundle strand cutting tip bundled in two or three sets are enclosed in the gap in the core region of the knitting storage portion. There is an effect that it can be completely sealed so as not to protrude outside the wire rope.

According to the seventh aspect of the present invention, in inserting the bundle strand between the twisted strands at the loop base end portion of the wire rope, first, in the first weaving step, the twist in the direction opposite to the twist of the wire rope. The bundle strands are knitted by inserting the strands between the strands, and performing this operation a plurality of times.Then, in the second knitting step, the bundle strands are knitted along the direction opposite to the twist of the wire rope, In the third half-insertion knitting step, six sets of fine bundle strands made of the second fine bundle are knitted in the direction opposite to the twisting direction of the wire rope.
Therefore, the cutting tip of the bundle strand pushed into the core region of the wire rope and the cutting tip of the second bundle of fine bundle strands are stored by weaving the bundle strand or the fine bundle strand of the second fine bundle. For this reason, bundle strands are knitted in a basket insertion state crossing in the direction opposite to the twist direction of the wire rope to form a knitted storage portion, and further, fine bundle strands are knitted in the basket insertion state to form a knitted storage portion. Will be formed.
In other words, the braided storage section in which the bundle strands and the fine bundle strands which are crossed in a mesh shape surround the periphery of the core region wraps the thorn which is the tip of the strand cutting tip or the thin strand cutting end portion, and the outside of the wire rope. There is an effect that can be sealed so as not to protrude.
When tensile stress or bending stress is applied during use as a wire rope sled rope, the bundle strands and fine bundle strands that are crossed in a mesh shape are reduced, so that the larger the tensile stress or bending stress is, the more the wire strand is wound. Since the turning eyes become closer and smaller, and a circumferential side wall without a gap is formed, a so-called knitting storage portion is formed, so that the bundle strand cutting tip and two sets are formed in the gap in the core region of the knitting storage portion. Alternatively, there is an effect that the thorns, which are the cutting ends of the thin bundle strands bundled in three sets, can be enclosed and completely sealed so as not to protrude outside the wire rope.

According to the invention described in claim 8, when the bundle strand is inserted between the twisted strands at the loop base end portion of the wire rope, first, in the first weaving step, the twist in the same direction as the wire rope twist is performed. The bundle strands are twisted along the knitted strands and knitted, and this operation is performed a plurality of times. Then, in the second knitting step, the bundle strands are knitted along the same direction as the wire rope twist. In the half-insertion knitting process, six sets of fine bundle strands comprising the second fine bundle are knitted in the same direction as the twist direction of the wire rope.
Therefore, the wire rope for storing the cutting tip of the bundle strand or the cutting tip of the thin bundle strand pushed into the core region of the wire rope by weaving the bundle strand or the fine bundle strand of the second fine bundle The bundle strands are knitted in a winding state wound in the same direction as the twisting direction of the yarn to form a knitted storage portion, and further the thin bundle strands are knitted in a winding state to form a knitted storage portion. .
That is, the strand strand that is the strand cutting tip or the strand bundle cutting tip is wrapped by the spirally wound bundle strand and the spirally wound fine bundle strand that surrounds the periphery of the core region. Thus, there is an effect that it can be sealed so as not to protrude outside the wire rope.
When tensile stress or bending stress is applied during use as a wire rope sled rope, the helically wound bundle strands and fine bundle strands are also reduced, so that the higher the tensile stress and bending stress, the more spirally wound. Since the eyes are tightly reduced and a circumferential side wall without a gap is formed, a so-called knitted storage portion is formed. Has the effect that it can be completely sealed so that the thorns, which are the cutting ends of the thin bundle strands bundled in three sets, are contained and cannot protrude outside the wire rope.

According to the ninth aspect of the present invention, the second fine bundle after being divided into the first fine bundle and the second fine bundle is the same direction as the twist of the wire rope in the third half-insertion knitting step or In the opposite direction, it is inserted between the stranded strands and knitted. Accordingly, the twisted wire rope for storing the cutting tip of the second bundle bundle strand pushed into the gap in the core region of the wire rope by weaving the second bundle bundle. In a state intersecting with the direction opposite to the direction or wound in the same direction, the fine bundle strands of the second fine bundle are knitted to form a knitted storage portion.
That is, the fine bundle strands are formed by the braided storage section in which the second fine bundle strands crossed in a mesh shape or the second fine bundle strands wound spirally surround the core region. There is an effect that it can be sealed so that the thorn which is the cutting tip portion of the wire is wrapped and cannot protrude to the outside of the wire rope.
And when tensile stress or bending stress is applied at the time of use as a wire rope sling rope, the fine bundle strands of the second fine bundle crossed in a mesh shape are reduced, and the mesh becomes larger as the tensile stress or bending stress is larger. As the tension strand and bending stress are larger, the spirally wound eyes are more tightly reduced by shrinking the second strands of the second bundle bundle spirally or smaller. Since it becomes a state in which a so-called knitted storage portion with a circumferential side wall without a gap is formed, a bundle strand cutting tip and two or three pairs of fine bundle strands bundled in the gap in the core region of the knitted storage portion There is an effect that it is possible to completely enclose the thorn which is the cutting tip portion so as not to protrude outside the wire rope.

According to the invention of claim 10, the outer layer wire after being separated into the inner layer wire and the outer layer wire is then twisted in the same direction as the twist of the wire rope or in the opposite direction in the third half-insertion knitting process. They are inserted and knitted between them. Therefore, crossing in the direction opposite to the twisting direction of the wire rope for storing the cut end of the thin bundle strand pushed into the gap in the core region of the wire rope by weaving the thin bundle strand of the outer layer wire In this state or wound in the same direction, the fine bundle strands are knitted to form a knitted storage portion.
That is, the fine bundle strands of the outer layer wires crossed in a mesh form or the fine bundle strands of the outer layer wires wound in a spiral shape are the leading ends of the fine bundle strands cut by the braided storage portion surrounding the periphery of the core region. There is an effect that it can be sealed so that the thorns are wrapped so as not to protrude outside the wire rope.
And when tensile stress or bending stress is applied when using it as a wire rope sling rope, the fine bundle strands of the outer layer wires that are meshed and crossed shrink, so that the larger the tensile stress and bending stress, the tighter the mesh The outer strands of strands wound in a spiral shape are reduced in size, and as the tensile and bending stresses increase, the spirally wound eyes become tighter and the circle without gaps. Since the circumferential side wall is in a state of forming a so-called knitting storage portion, it is a bundle strand cutting tip portion and a narrow bundle strand cutting tip portion bundled in two or three sets in the gap in the core region of the knitting storage portion. There is an effect that the thorns can be completely enclosed so that the thorns are contained and cannot protrude outside the wire rope.

According to the eleventh aspect of the present invention, after the inner layer wire is separated into the inner layer wire and the outer layer wire, the inner layer wire is twisted in the same direction as the twist of the wire rope or in the opposite direction in the third half insertion braiding process. They are inserted and knitted between them. Therefore, the braided strands of the inner-layer wire are knitted to reverse the twist direction of the wire rope for storing the cutting tip of the inner-layer wire-strand strand pushed into the gap in the core region of the wire rope. In a state intersecting with each other or wound in the same direction, the thin bundle strands of the inner layer wire are knitted to form a knitted storage portion.
That is, the fine bundle strands of the inner bundle wire crossed in a mesh form or the fine bundle strand of the inner coat wire wound in a spiral form is the leading end portion of the fine bundle strand cut by the braided storage portion surrounding the periphery of the core region. There is an effect that it can be sealed so that the thorns are wrapped so as not to protrude outside the wire rope.
And when tensile stress or bending stress is applied when using it as a wire rope sling rope, the fine bundle strands of the inner layer wires that are meshed and crossed shrink, and the mesh becomes tighter and smaller as the tensile stress increases. Alternatively, the inner strand wire bundle strands wound spirally are reduced, and the larger the tensile stress, the tighter the spirally wound eyes become, and the circumferential side walls without gaps, so-called knitting. Since it is in a state in which a knitted storage portion is formed, the bundle strand cutting tip portion and the thorn which is a bundle bundle cutting tip portion bundled in two or three sets are sealed in the core region of the knitted storage portion, and the outside of the wire rope There is an effect that it can be completely sealed so as not to protrude.

  According to the invention described in claim 12, since it is a slingless wire rope slinging cable manufactured by the method of manufacturing a slingless wire rope sling rope, the free end of the strand as well as the core rope is in the gap in the core region. By returning to, the cut portion of the strand does not protrude from the surface of the wire rope, and the hollow portion of the core region is buried, and the steel properties and strength of the wire rope are dramatically improved along with safety during use. There is an effect that can be improved.

(3) The third bundle strand 3 is inserted from between the strand strands B and C on the main wire 11a side of the wire rope 11, and the space between the strands A and B is pulled out.

(4) The fourth bundle strand 4 is inserted between the twisted strands C and D on the main wire 11a side of the wire rope 11 and the space between the twisted strands B and C is removed.

(5) The fifth bundle strand 5 is inserted from between the strand strands D and E on the main wire 11a side of the wire rope 11, and the space between the strands C and D is pulled out.

(6) The sixth bundle strand 6 is inserted from between the strand strands E and F on the main wire 11a side of the wire rope 11 and pulled between the strand strands D and E.

  In this way, the knitted storage portion is formed by weaving the bundle strand into the twisted strand of the wire rope.

V-a1. [Narrow bundle strand forming process]
Thus, the six sets of bundle strands 1 to 6 are completely inserted through the twisted strands A to F by the cage insertion and winding methods. Then, each protruding end of the bundle strands 1 to 6 is further divided into two sets of bundles to form a first fine bundle and a second fine bundle. That is, a fine bundle strand forming process is performed in which the fine bundle strands 1c to 6c of the first fine bundle and the fine bundle strands 1d to 6d of the second fine bundle are divided into two.

VI-a1. [First fine bundle cutting step]
The fine bundle strands 1c to 6c of the first fine bundle of the six bundle bundles 1 to 6 are subjected to the first fine bundle cutting step of cutting at the position of the surface of the wire rope, and the six second fine bundles, that is, the six sets. The thin bundle strands 1d to 6d are left (see FIG. 6). At this time, the core rope 7 is drawn and cut from between the twisted strands A to F, and a gap 11b in the core region is formed at a location where a part of the core rope 7 at the center of the twisted strands A to F is removed.

VII-a1. [First fine bundle tip pushing process]
The cutting ends of the six strands 1c to 6c of the first bundle of the first six bundles, so-called six first bundles, are pulled out of the core rope 7 at the center of the stranded strands A to F. A first narrow bundle tip pushing process of pushing into the generated gap 11b in the core region is performed (see FIG. 6). At this time, the bundle strand encloses the thorn which is the distal end portion of the strand cutting by the knitted storage portion surrounding the periphery of the core region.

VIII-a1. [Third half-insertion process of winding]
The second thin bundle strands 1d to 6d that are left protruding are subjected to a third half-insertion knitting process of being inserted between the twisted strands A to F by an operation by a half-insertion winding method. That is, as shown in FIG. 6, the first to sixth sets of second fine bundle strands 1 d to 6 d are inserted between predetermined twist strands A to F while being wound in the same direction as the twist.

(1) For example, as shown in FIG. 6, the first set of second thin bundle strands 1d is inserted between the strand strands A and F on the main line 11a side of the wire rope 11, and the twisted strands E and F are inserted. Remove the space.

(2) Insert the second strand of the second bundle of thin strands 2d from between the strand strands A and B on the main wire 11a side of the wire rope 11 and remove the space between the strands of strands A and F.

(3) Insert the third strands 3d of the second bundle of strands from between the strand strands B and C on the main wire 11a side of the wire rope 11, and remove the space between the strands A and B.

(4) Insert the 4th set of second bundles of fine strands 4d from between the strand strands C and D on the main wire 11a side of the wire rope 11 and remove the space between the strands B and C.

(5) Insert the fifth strand 5d of the second bundle of strands from between the strand strands D and E on the main wire 11a side of the wire rope 11, and remove the space between the strands C and D.

(6) The 6th set of the second fine bundle strand 6d is inserted from between the strand strands E and F on the main wire 11a side of the wire rope 11 and pulled out between the strand strands D and E.

  Thus, the first two insertion operations of the strands 1 to 6d of the six second bundles into the twisted strands A to F by the winding method are completed.

  Next, the operation | work by the winding method of the 2nd time of six sets of 2nd bundle strand 1d-6d of a 2nd bundle is performed in the same procedure. This will be described in detail with reference to FIG.

(1) For example, as shown in FIG. 7, the first set of second thin bundles 1 d of strands is inserted between the strands A and F on the main line 11 a side of the wire rope 11, and the strands E and F are inserted. Remove the space.

(2) Insert the second strand of the second bundle of thin strands 2d from between the strand strands A and B on the main wire 11a side of the wire rope 11 and remove the space between the strands of strands A and F.

(3) Insert the third strands 3d of the second bundle of strands from between the strand strands B and C on the main wire 11a side of the wire rope 11, and remove the space between the strands A and B.

(4) Insert the 4th set of second bundles of fine strands 4d from between the strand strands C and D on the main wire 11a side of the wire rope 11 and remove the space between the strands B and C.

(5) Insert the fifth strand 5d of the second bundle of strands from between the strand strands D and E on the main wire 11a side of the wire rope 11, and remove the space between the strands C and D.

(6) The 6th set of the second fine bundle strand 6d is inserted from between the strand strands E and F on the main wire 11a side of the wire rope 11 and pulled out between the strand strands D and E.

  With the above, the second insertion operation of the six strands of the second thin bundles 1d to 6d through the twisted strands A to F by the respective winding methods is completed.

  Thus, the braided storage portion is formed by weaving the fine bundle strands into the twisted strands of the wire rope.

  In the third half-insertion knitting process described above, the winding operation in half-insertion is performed twice, but is not particularly limited to two, and may be performed twice or more.

IX-a1. [Second fine bundle cutting step and second fine bundle tip pushing step]
When the operation of winding two to three times is completed, a second fine bundle cutting step of cutting six sets of fine bundle strands 1d to 6d protruding at the wire rope surface position is performed. The cut portion of the cut second fine bundle is subjected to a second fine bundle tip pushing process for pushing into the gap 11b in the core region of the twisted strands A to F.

  For example, as shown in FIG. 8, two sets of each of the six bundles of the second bundles 1 d to 6 d are bundled to tap the root, and three sets of taping strand bundles are newly formed. Then, the thin bundle strand protruding from the tip of the taping is cut and the tip portions of the three sets of taping bundle strands are inserted into the gap 11b in the core region. Then, the heart rope 7 drawn out to the outside is returned to the gap 11b in the core region. The thorns, which are the tip portions of the taping bundle strands that are bundled in two sets, can be enclosed in the gap in the core region of the braided storage portion and completely sealed so as not to protrude outside the wire rope. At this time, when two pairs of fine bundle strands are bundled, the diameter becomes substantially the same as the diameter of the bundle strand, and it is impossible to protrude from the gap in the core region to the outside of the wire rope. Then, the cut core wire once drawn to the outside is returned to the gap in the core region to eliminate the gap, and the direction of the thorn which is the tip of the thin bundle strand bundled in two or three sets is set in the longitudinal direction of the wire rope. The wire rope can be prevented from protruding to the outside.

  It should be noted that the six bundles of the second bundle of thin bundles 1d to 6d described in FIG. 8 are bundled two by two so as to fit in the gap 11b in the core region. Three strands may be bundled and stored in the gap 11b in the core region.

  Through the above steps I-a1 to IX-a1, a wire rope sling without rope is completed (see FIG. 50).

  In this way, the knitted storage portion is formed by weaving the bundle strand into the twisted strand of the wire rope.

  As shown in FIG. 9, six sets of bundle strands 1 to 6 are completely inserted into the twisted strands A to F by the cage insertion method.

V-b1. [Narrow bundle strand forming process]
With the above, the six sets of bundle strands 1 to 6 have been inserted through the twisted strands A to F by each of three methods of cage insertion and cage insertion once. Then, each protruding end of the bundle strands 1 to 6 is further divided into two sets of bundles to form a first fine bundle and a second fine bundle. That is, a fine bundle strand forming process is performed in which the fine bundle strands 1c to 6c of the first fine bundle and the fine bundle strands 1d to 6d of the second fine bundle are divided into two.

VI-b1. [First fine bundle cutting step]

The thin bundle strands 1d to 6d are left (see FIG. 10). At this time, the core rope 7 is drawn and cut from between the twisted strands A to F, and a gap 11b in the core region is formed at a location where a part of the core rope 7 at the center of the twisted strands A to F is removed.

VII-b1. [First fine bundle tip pushing process]

IX-b1. [Second fine bundle cutting step and second fine bundle tip pushing step]
When the operation of winding two to three times is completed, a second fine bundle cutting step of cutting six sets of fine bundle strands 1d to 6d protruding at the wire rope surface position is performed. The cut portion of the cut second fine bundle is subjected to a second fine bundle tip pushing process for pushing into the gap 11b in the core region of the twisted strands A to F.

The thorns, which are the tip portions of the taping bundle strands that are bundled in two sets, can be enclosed in the gap in the core region of the braided storage portion and completely sealed so as not to protrude outside the wire rope. At this time, when two pairs of fine bundle strands are bundled, the diameter becomes substantially the same as the diameter of the bundle strand, and it is impossible to protrude from the gap in the core region to the outside of the wire rope. Then, the cut core wire once drawn to the outside is returned to the gap in the core region to eliminate the gap, and the direction of the thorn which is the tip of the thin bundle strand bundled in two or three sets is set in the longitudinal direction of the wire rope. The wire rope can be prevented from protruding to the outside.

That is, in the same procedure (1) to (6), the insertion work by the winding method is performed, and the insertion work by the winding method of the six sets of bundle strands 1 to 6 is completed.

  In this way, the knitted storage portion is formed by weaving the bundle strand into the twisted strand of the wire rope.

V-c1. [Narrow bundle strand forming process]
Thus, the six sets of bundle strands 1 to 6 are completed to be inserted into the twisted strands A to F by the three winding methods and the one winding method. Then, each protruding end of the bundle strands 1 to 6 is further divided into two sets of bundles to form a first fine bundle and a second fine bundle. That is, a fine bundle strand forming process is performed in which the fine bundle strands 1c to 6c of the first fine bundle and the fine bundle strands 1d to 6d of the second fine bundle are divided into two.

VII-c1. [First fine bundle tip pushing process]
The cutting ends of the six strands 1c to 6c of the first bundle of the first six bundles, so-called six first bundles, are pulled out of the core rope 7 at the center of the stranded strands A to F. A first fine bundle tip pushing process of pushing into the generated gap 11b in the core region is performed. At this time, the bundle strand encloses the thorn which is the distal end portion of the strand cutting by the knitted storage portion surrounding the periphery of the core region.

When the operation | work of 2-3 times of basket insertion is complete | finished, the 2nd fine bundle cutting process which cut | disconnects 6 sets of 2nd fine bundle strands 1d-6d protruded in the wire rope surface position is performed. The cut portion of the cut second fine bundle is subjected to a second fine bundle tip pushing process for pushing into the gap 11b in the core region of the twisted strands A to F.

  For example, as shown in FIG. 16, two sets of six bundles of each of the second bundles 1d to 6d are bundled to tap the root, and three sets of taping strand bundles are newly formed. Then, the thin bundle strand protruding from the tip of the taping is cut and the tip portions of the three sets of taping bundle strands are inserted into the gap 11b in the core region.

At this time, when two pairs of fine bundle strands are bundled, the diameter becomes substantially the same as the diameter of the bundle strand, and it is impossible to protrude from the gap in the core region to the outside of the wire rope. Then, the cut core wire once drawn to the outside is returned to the gap in the core region to eliminate the gap, and the direction of the thorn which is the tip of the thin bundle strand bundled in two or three sets is set in the longitudinal direction of the wire rope. The wire rope can be prevented from protruding to the outside.

At this time, when two pairs of fine bundle strands are bundled, the diameter becomes substantially the same as the diameter of the bundle strand, and it is impossible to protrude from the gap in the core region to the outside of the wire rope. Then, the cut core wire once drawn to the outside is returned to the gap in the core region to eliminate the gap, and the direction of the thorn which is the tip of the thin bundle strand bundled in two or three sets is set in the longitudinal direction of the wire rope. The wire rope can be prevented from protruding to the outside.

At this time, when two pairs of fine bundle strands are bundled, the diameter becomes substantially the same as the diameter of the bundle strand, and it is impossible to protrude from the gap in the core region to the outside of the wire rope. Then, the cut core wire once drawn to the outside is returned to the gap in the core region to eliminate the gap, and the direction of the thorn which is the tip of the thin bundle strand bundled in two or three sets is set in the longitudinal direction of the wire rope.

Process, II-a1. Preparatory work process and III-c1. First knitting process of winding and IV-c1. This is the same as the second weaving step for winding, and duplicate explanation is omitted.

V-c2. [Narrow bundle strand forming process]
Thus, the six sets of bundle strands 1 to 6 are completed to be inserted into the twisted strands A to F by the three winding methods and the one winding method. Then, a fine bundle strand forming step is performed in which the protruding ends of the bundle strands 1 to 6 are separated into the fine bundle strands 1a to 6a of the inner layer wire and the fine bundle strands 1b to 6b of the outer layer wire. In general, a composite wire constituting a single strand is composed of inner and outer layer wires, which are referred to as inner layer wires and outer layer wires, and here, an operation of separating them into inner and outer layer wires is performed. In the ninth embodiment, as in the seventh embodiment, the first thin bundle is described as an inner layer line, and the second thin bundle is described as an outer layer line.

VI-c2. [First fine bundle cutting process as inner layer wire]
Six pairs of bundle strands 1 to 6 of inner layer wire thin bundle strands 1a to 6a are subjected to a first fine bundle cutting step of cutting at the position of the surface of the wire rope, and six sets of outer layer wires, that is, six sets of fine bundle strands. Leave 1b-6b (see FIGS. 27, 46 and 47). At this time, the core rope 7 is pulled out from between the strands A to F and cut (see FIG. 48), and a portion of the core rope 7 at the center of the twist strands A to F is removed, and the gap in the core region is removed. 11b is formed.

VII-c2. [First fine bundle tip pushing process as inner layer wire]
The tip cut portions of the first bundles of strands 1a to 6a as six sets of inner layer wires that have been cut, so-called six inner layer wire spikes, are part of the core rope 7 at the center of the stranded strands A to F. A first fine bundle tip pushing process is performed as an inner layer line to be pushed into the void 11b in the core region generated by the extraction. At this time, the bundle strand encloses the thorn which is the distal end portion of the strand cutting by the knitted storage portion surrounding the periphery of the core region.

VIII-c2. [The third half weaving process of basket insertion]
The thin bundle strands 1b to 6b of such outer layer wires that remain protruding are subjected to a third half-insertion knitting process of being inserted between the twisted strands A to F by an operation by a cage insertion method by half insertion. That is, as shown in FIG. 27, the thin bundle strands 1b to 6b of the first to sixth sets of outer layer wires are inserted between predetermined twisted strands A to F while being wound in a direction opposite to the twist.

(1) For example, as shown in FIG. 27, between the twisted strands E and F by inserting the thin bundle strand 1b of the first outer layer wire from between the twisted strands A and B on the main wire 11a side of the wire rope 11. Unplug.

(2) The second bundle of thin strands 2b of the outer layer wire is inserted between the twisted strands B and C on the main wire 11a side of the wire rope 11, and the space between the twisted strands A and F is removed.

(3) The third bundle of thin strands 3b of the outer layer wire is inserted from between the strand strands C and D on the main wire 11a side of the wire rope 11, and the space between the strands A and B is pulled out.

(4) The fourth bundle of thin strands 4b of the outer layer wire is inserted between the twisted strands D and E on the main wire 11a side of the wire rope 11, and the space between the twisted strands B and C is removed.

(5) Insert the thin bundle strands 5b of the fifth set of outer layer wires from between the strand strands E and F on the main wire 11a side of the wire rope 11, and remove the space between the strand strands C and D.

(6) The sixth bundle of outer layer wire thin bundle strands 6b is inserted between the strand strands A and F on the main wire 11a side of the wire rope 11 and pulled between the strand strands D and F.

  Thus, the six strands 1b to 6b of outer-layer wires are completely inserted through the twisted strands A to F by the cage insertion method.

  Next, the operation | work by the 2nd time cage | basket insertion method of the 6 bundles of outer layer wire fine bundle strands 1b-6b is performed in the same procedure.

(1) For example, as shown in FIG. 28, between the stranded strands B and C by inserting the thin bundle strands 1b of the first outer layer wire from between the stranded strands D and E on the main wire 11a side of the wire rope 11. Unplug.

(2) The second bundle of thin strands 2b of the outer layer wire is inserted between the twisted strands E and F on the main wire 11a side of the wire rope 11, and the space between the twisted strands C and D is removed.

(3) The third bundle of thin strands 3b of the outer layer wire is inserted between the twisted strands A and F on the main wire 11a side of the wire rope 11, and the space between the twisted strands D and E is removed.

(4) Insert the fourth bundle of thin strands 4b of the outer layer wires from between the strand strands A and B on the main wire 11a side of the wire rope 11, and remove the space between the strands E and F.

(5) The fifth bundle of outer strands 5b is inserted from between the strand strands B and C on the main wire 11a side of the wire rope 11, and the space between the strands A and F is pulled out.

(6) The sixth bundle of the outer layer wire thin bundle strands 6b is inserted between the twisted strands C and D on the main wire 11a side of the wire rope 11 and pulled between the twisted strands A and B.

  Then, the second bundle of strands 1 to 6b of the six sets of outer layer wires is inserted into the twisted strands A to F by each method of cage insertion.

  Thus, the braided storage portion is formed by weaving the fine bundle strands into the twisted strands of the wire rope.

  In the above-described third half-weaving process, the basket insertion operation in half-insertion is performed twice. However, the operation is not particularly limited to two times, and may be twice or more.

IX-c2. [Second fine bundle cutting step as outer layer wire and second fine bundle tip pushing step as outer layer wire]
When the operation | work of 2 or 3 times basket insertion is complete | finished, the 2nd fine bundle cutting process as an outer layer line which cuts the 6 bundle outer strand thin bundle strands 1b-6b protruded in the wire rope surface position is performed. The cut portion of the cut outer layer wire performs a second fine bundle tip pushing process as an outer layer wire pushed into the gap 11b in the core region of the stranded strands A to F.

  For example, as shown in FIG. 29, two sets of each of the six bundles of outer layer wires 1b to 6b are bundled to tap the root, and three sets of taping strand bundles are newly formed. The thin bundle strands protruding from the tip of the tape are cut, and the tip portions of the three sets of taping bundle strands are inserted into the gap 11b in the core region (see FIG. 49). Then, the heart rope 7 drawn out to the outside is returned to the gap 11b in the core region. The thorns, which are the tip portions of the taping bundle strands that are bundled in two sets, can be enclosed in the gap in the core region of the braided storage portion and completely sealed so as not to protrude outside the wire rope. At this time, when two pairs of fine bundle strands are bundled, the diameter becomes substantially the same as the diameter of the bundle strand, and it is impossible to protrude from the gap in the core region to the outside of the wire rope. Then, the cut core wire once drawn to the outside is returned to the gap in the core region to eliminate the gap, and the direction of the thorn which is the tip of the thin bundle strand bundled in two or three sets is set in the longitudinal direction of the wire rope. The wire rope can be prevented from protruding to the outside.

  In addition, the six sets of outer layer wire thin bundle strands 1b to 6b described in FIG. 29 are bundled two by two so as to be stored in the gap 11b in the core region, but the six sets of outer layer wire thin bundle strands 3 They may be bundled one by one and stored in the gap 11b in the core region.

  Through the above steps I-a1 to II-a1, III-c1 to IV-c1, and V-c2 to IX-c2, a wire rope sling without rope is completed (see FIG. 50).

(6) The sixth set of inner layer wire fine bundle strands 6a is inserted between the strand strands E and F on the main wire 11a side of the wire rope 11 and pulled between the strand strands D and E.

  Thus, the six strands 1a to 6a of the inner-layer wires are completely inserted through the twisted strands A to F by the winding method.

  Next, the operation | work by the winding method of the 2nd time of six sets of inner layer wire fine bundle strands 1a-6a is performed in the same procedure. This will be described in detail with reference to FIG.

When the operation | work of 2 to 3 times winding is complete | finished, the 2nd fine bundle cutting process as an inner layer line which cuts the 6 bundle inner layer wire fine bundle strands 1a-6a protruded in the wire rope surface position is performed. The cut portion of the cut inner layer wire performs a second fine bundle tip pushing process as an inner layer wire pushed into the gap 11b in the core region of the twisted strands A to F.

  For example, as shown in FIG. 35, two sets of the six thin bundle strands 1a to 6a of the inner layer wire are bundled to tap the root, and three sets of taping strand bundles are newly formed. The thin bundle strands protruding from the tip of the tape are cut, and the tip portions of the three sets of taping bundle strands are inserted into the gap 11b in the core region (see FIG. 49). Then, the heart rope 7 drawn out to the outside is returned to the gap 11b in the core region. The thorns, which are the tip portions of the taping bundle strands that are bundled in two sets, can be enclosed in the gap in the core region of the braided storage portion and completely sealed so as not to protrude outside the wire rope. At this time, when two pairs of fine bundle strands are bundled, the diameter becomes substantially the same as the diameter of the bundle strand, and it is impossible to protrude from the gap in the core region to the outside of the wire rope. Then, the cut core wire once drawn to the outside is returned to the gap in the core region to eliminate the gap, and the direction of the thorn which is the tip of the thin bundle strand bundled in two or three sets is set in the longitudinal direction of the wire rope. The wire rope can be prevented from protruding to the outside.

  It should be noted that the six bundles of the second bundle of fine bundles 1d to 6d are bundled two by two so as to be stored in the gap 11b in the core region, but the six sets of the second bundle of fine bundle strands are arranged three by three. They may be bundled and stored in the gap 11b in the core region.

VI-b3. [First fine bundle cutting step as outer layer wire]
The thin bundle strands 1b to 6b of the outer layer wires of the six sets of bundle strands 1 to 6 are subjected to the first fine bundle cutting process as outer layer wires to be cut at the position of the surface of the wire rope, and six sets of inner layer wires, that is, six sets The thin bundle strands 1a to 6a are left (see FIG. 36). At this time, the core rope 7 is pulled out from between the strands A to F and cut (see FIG. 48), and a portion of the core rope 7 at the center of the twist strands A to F is removed, and the gap in the core region is removed. 11b is formed.

VII-b3. [First fine bundle tip pushing process as outer layer wire]
The tip cut portions of the six cut strand bundles that are cut, so-called six outer layer wire thorns, are in the void 11b in the core region generated by pulling out part of the core rope 7 at the center of the twisted strands A to F. A first fine bundle tip pushing process as an outer layer line to be pushed in is performed. At this time, the bundle strand encloses the thorn which is the distal end portion of the strand cutting by the knitted storage portion surrounding the periphery of the core region.

VIII-b3. [Third half-insertion process of winding]
The thin bundle strands 1a to 6a of the inner-layer wire that is still protruding are subjected to a third half-insertion knitting process of being inserted between the twisted strands A to F by an operation by a half-insertion winding method. That is, as shown in FIG. 36, the thin bundle strands 1a to 6a of the first to sixth sets of inner layer wires are inserted between predetermined twisted strands A to F while being wound in the same direction as the twist.

(1) For example, as shown in FIG. 36, between the twisted strands B and C by inserting the thin bundles 1a of the first set of inner layer wires from between the twisted strands C and D on the main wire 11a side of the wire rope 11. Unplug.

(2) Insert the second bundle of inner strand thin strands 2a from between the strand strands D and E on the main wire 11a side of the wire rope 11 and remove the space between the strands C and D.

(3) Insert the third bundle of thin strands 3a of the inner layer wires from between the strand strands E and F on the main wire 11a side of the wire rope 11, and remove the space between the strands D and E.

(4) Insert the fourth bundle of the inner layer wire bundle strands 4a from between the strand strands A and F on the main wire 11a side of the wire rope 11 and remove the space between the strands E and F.

(5) Insert the fifth strand of the inner-layer wire bundle 5a from between the strand strands A and B on the main wire 11a side of the wire rope 11 and remove the space between the strands A and F.

(6) The sixth set of inner strand thin bundle strands 6a are inserted between the strand strands B and C on the main wire 11a side of the wire rope 11 and pulled between the strands A and B.

  Thus, the six strands 1a to 6a of the inner layer wire complete the first insertion operation into the twisted strands A to F by the respective winding methods.

  Next, as shown in FIG. 37, the work by the second winding method of the six sets of inner layer wire fine bundle strands 1a to 6a is performed in the same procedure as the above (1) to (6).

  Then, for the six sets of inner layer wire thin bundle strands 1a to 6a, the second insertion operation into the twisted strands A to F by each method of winding is completed.

  Thus, the braided storage portion is formed by weaving the fine bundle strands into the twisted strands of the wire rope.

  In the third half-insertion knitting process described above, the winding operation in half-insertion is performed twice, but is not particularly limited to two, and may be performed twice or more.

IX-b3. [Second fine bundle cutting step as inner layer wire and second fine bundle tip pushing step as inner layer wire]
When the operation | work of 2 to 3 times winding is complete | finished, the 2nd fine bundle cutting process as an inner layer line which cuts the 6 bundle inner layer wire fine bundle strands 1a-6a protruded in the wire rope surface position is performed. The cut portion of the cut inner layer wire performs an inner layer wire (second fine bundle) tip pushing process for pushing into the gap 11b in the core region of the stranded strands A to F.

  For example, as shown in FIG. 38, two sets of each of the six bundles of inner-layer wires 1a to 6a are bundled to tap the root to form three sets of taping strand bundles, and then taping. The thin bundle strands protruding from the tips of the tape are cut, and the tip portions of the three sets of taping bundle strands are inserted into the gap 11b in the core region. Then, the heart rope 7 drawn out to the outside is returned to the gap 11b in the core region. The thorns, which are the tip portions of the taping bundle strands that are bundled in two sets, can be enclosed in the gap in the core region of the braided storage portion and completely sealed so as not to protrude outside the wire rope. At this time, when two pairs of fine bundle strands are bundled, the diameter becomes substantially the same as the diameter of the bundle strand, and it is impossible to protrude from the gap in the core region to the outside of the wire rope. Then, the cut core wire once drawn to the outside is returned to the gap in the core region to eliminate the gap, and the direction of the thorn which is the tip of the thin bundle strand bundled in two or three sets is set in the longitudinal direction of the wire rope. The wire rope can be prevented from protruding to the outside.

  It should be noted that the six sets of inner layer wire thin bundle strands 1a to 6a described in FIG. 38 are bundled two by two so as to be stored in the gap 11b in the core region, but the six sets of inner layer wire thin bundle strands 3 They may be bundled one by one and stored in the gap 11b in the core region.

  Through the steps I-a1 to III-a1, IV-b1, V-a2, and VI-b3 to IX-b3, a wire rope slinging line without barbs is completed (see FIG. 50).

At this time, when two pairs of fine bundle strands are bundled, the diameter becomes substantially the same as the diameter of the bundle strand, and it is impossible to protrude from the gap in the core region to the outside of the wire rope. Then, the cut core wire once drawn to the outside is returned to the gap in the core region to eliminate the gap, and the direction of the thorn which is the tip of the thin bundle strand bundled in two or three sets is set in the longitudinal direction of the wire rope.
