Description

Technical area

The present invention generally relates to synthetic ropes, and more specifically to a rope which is preferably made of synthetic polymer material, which has a fairly high breaking strength and which also has a fairly low weight compared to steel wire rope, and which can be used with power blocks, traction winches, motor-driven winches, motorized drums, drum winches, motorized walking winches and generally any mechanical turning and/or rotating element capable of applying force to a rope (hereafter collectively referred to as "power blocks"). Such synthetic ropes include, but are not limited to tow ropes, tow lines, trawl warps (also known as "trawl ropes"), deepwater hoisting/lowering ropes, power block rigged mooring lines, power block rigged derrick anchor ropes used with blocks and also with power blocks, "superwide "-ropes and paravan cables used in seismic monitoring, including but not limited to those used in towing seismic arrays, helicopter ropes, ropes for sport sailing, rigging ropes for pleasure craft, including but not limited to sailing vessels, running rigging, power block-rigged anchor rope, towing lines and any other type of rope and/or cable without exception (the terms "rope" and "cable" are used synonymously for the purpose of the present invention).

Background and known technique

High-strength synthetic ropes formed mainly from superfibres, such as Dyneema® (formed from UHMWPE), PBO Zylon and others, are important substitutes for steel wire ropes in many applications, and especially applications where personal safety and life are at risk as a result of handling steel wire rope. Such applications include, but are not limited to, applications utilizing power blocks. In such applications, the energy released from a wire rope breaking while under tension can be sufficient to cause a recoiling portion of the wire rope to cut through a steel plate, and is known to tear limbs and kill occupants and around the area by the wire rope. In addition to disabling and fatal injuries resulting from wire rope breaking while under tension, the use of wire rope, due to its heavy weight, results in an unacceptable risk of back injury to persons responsible for handling the wire rope, including loading the wire rope into egress equipment, including cranes, or handling the steel wire rope in dynamic applications, such as towing ropes and mooring lines. In contrast, the latest technology in high-strength synthetic ropes has a low weight and is not a significant risk factor for back injury in people responsible for running the synthetic rope, nor does it store enough kinetic energy at the breaking point to make them particularly dangerous if they were to break while under tensile load. One thus immediately understands that it is important to replace steel wire ropes with high-strength synthetic ropes at least for purposes and applications involving power blocks, especially cranes and other applications that use drum winches and also use walking winches, as well as all other purposes and applications where the rope and/ or the cable is used in places where people are near parts of the rope and/or cable - or in places where people could be hit by parts of the rope or associated equipment if the rope and/or cable breaks and is pushed back.

However, due to problems associated with running high-strength synthetic ropes with power blocks, wire ropes are still used in applications where their high weight compared to synthetic ropes causes back injuries to people running the wire ropes and also in applications where wire ropes if they break under load can maim or kill people nearby.

A main problem that slows down the spread of high-strength synthetic ropes as a replacement for steel wire ropes for use in connection with power blocks and other applications is that high-strength synthetic ropes exhibit fairly low surface friction and thus relatively little traction compared to the surface friction and traction exhibited by steel wire ropes , especially when run out with power blocks, or in applications that require different parts of the rope to grip themselves, such as in logging operations. The low surface friction, especially with wet or greasy surfaces, allows the high-strength synthetic ropes to slide on the gripping surface of power blocks, and also to slide on the corresponding surfaces of successive layers of the synthetic rope. When the high-strength synthetic rope is loaded and stored on a high-traction drum winch, the low surface friction allows the layers of the rope loaded on the drum winch to slip, with the result that later wraps of the high-strength synthetic rope stored on the drum winch under tensile load are often pinched between previously formed wraps of the rope, thereby causing tangles and tangles. The tangles and vases cause economic losses as a result of downtime caused by a need to dissolve the tangles and vases and repair equipment failures caused by such tangles and vases. However, much more seriously, the tangles and vases present a major hazard to the safety and life and limb of crew and equipment operators working near the high-strength synthetic ropes, as the tangles and vases can cause violent shock impulses when the tangles and vases are released up to and including causing an abrupt cessation of tensile loading followed by a sudden tensile shock load which, although the high strength synthetic rope does not break, is known to have caused failure of equipment with which the high strength synthetic rope is run out, such as blocks and pulleys, which results in an abrupt change in the position of both such associated equipment and the high strength synthetic rope under high speeds and high tensile loads, and which is known to have resulted in fatalities.

In addition to the very serious problems related to the safety and health of people on and around a steel wire rope under tension, there are still very real and serious economic consequences caused by the relatively low tensile strength of synthetic superfibre ropes compared to steel wire ropes which are troublesome and increasingly cause major economic damage in certain industries. One of these industries is the search for and development of oil deposits. In this industry, there is a growing need for research and installation of equipment in increasingly deeper waters, known as the deep sea. This growing need for research and installation of equipment in deep water requires the use of increasingly longer cables. As a result of the relatively high density of steel wire cable in air and water, including salt water, the gradually and increasingly longer cable lengths make research and development work difficult due to the fact that the weight of the metal cables takes up so much payload with its own weight that it often remains for low payload capacity for other equipment. In extreme cases, the steel wire used in deep sea operations, and when long lengths are used, can break under its own weight. Furthermore, existing cranes, lifting equipment and winches on vessels are not capable of carrying the weight required to run out the necessary lengths of cable for operations in increasingly deeper water. In addition to the long-felt and urgent safety needs for a synthetic rope that generates little energy and has sufficient traction to replace steel wire rope, one immediately understands that there is a long-felt and urgent economic need in the industry for a high-strength synthetic rope with low weight that exhibits sufficient tensile strength to replace steel wire ropes in applications that today face serious economic challenges as a result of the use of steel wire ropes and/or cables, for example in deep sea applications.

Attempts to resolve this issue include:

a) forming sheaths of steel wire around strength elements formed from high-strength synthetic fibers (the term "fibre" can be used here synonymously with the term "filament"); b) mixing relatively low strength synthetic fibers exhibiting relatively high friction with super fibers exhibiting relatively low friction, forming cord members from such combinations of fibers and then forming an outer cladding around a high strength synthetic strength member with such cord members; c) wrapping cord parts formed of high tenacity super fibers with a thin layer of cord parts formed of fibers of relatively high friction and relatively low tenacity, and forming a rope from such wrapped cord parts (as shown in US 7,735,308 and US 7,908,955); and d) forming synthetic claddings around strength elements where either the entire strength element is sealed from the surroundings by the synthetic cladding,

or where the synthetic covering lies between adjacent cord parts forming the outer layer of cord parts forming the rope and/or cable, so that the outer surface of the rope and/or cable includes both the synthetic covering and cord parts of the cable projecting from the synthetic covering .

Known designs of synthetic rope and steel wire rope intended for use where a high tensile force is desired either: a) does not include any covering around the strength element, the strength element being mixed with cord parts including cord parts with relatively low strength and high friction; b) includes a cover around the strength element, parts of the strength element projecting from the cladding so that these parts of the strength element can come into contact with working surfaces and provide traction; c) includes a final layer of chord elements that form a cover around the strength element, where this last layer of chord elements either has the same or a similar pitch (pitch) as a majority of the chord elements that form the rest of the strength element, or a greater pitch than the majority of the chord elements that forms the strength element, and is made and designed to share load-carrying capacity in accordance with all or the majority of the chord parts that form the strength element.

Another technique teaches attaching a coating with relatively high friction directly to a strength element, or attaching a coating with low friction directly to a strength element or otherwise forming a strength element with super fibers that have relatively low friction, but attaching to the outside of the strength element a substance which has higher friction than the super fibers that form the strength element. For example, a substance with relatively high friction can be attached directly to the strength element by coating the strength element with a substance with relatively high friction, or by spinning the strength element with fibers and/or cord parts (including yarn) formed from a substance with relatively high friction, or by coating and/or wrapping cord parts that form the strength element with a substance with relatively high friction and then forming the strength element with these cord parts so that the outer surface of this strength element is completely or mainly covered by the substance with relatively high friction (such as, for example, shown in US 7,735,308 and US 7,908,955).

Known techniques for forming a rope and/or cable with a high friction strength element include an embodiment of such rope and/or cable in which the rope and/or cable exhibits a lateral deformation when subjected to a certain tensile force and when brought against a hard working surface on a traction winch and/or drum winch, i.e. a lateral deformation of the cross-sectional shape of the rope and/or cable exhibited in such cases by known wire ropes, it being the trend in the industry and state-of-the-art to preserve the ability of a rope with high tensile force to exhibit such lateral deformation, and it is the dominant belief in the industry that such lateral deformation is important to maintain and/or maximize the rope's and/or cable's ability to exhibit a desired and necessary tensile force.

However, no prior art has presented a suitable solution to the problem of vases and entanglements that occur when using high strength synthetic rope with power blocks.

Due to the economic consequences of the low surface friction exhibited by high-strength synthetic ropes, especially in wet and/or greasy environments, steel wire ropes are therefore still often used even in cases where loss of life and limb is likely, and indeed occurs if the loaded and/or the stretched wire rope breaks.

One therefore immediately understands that there is a long-felt and urgent need within the industry for a high-strength synthetic rope that can be used unproblematically in connection with power blocks without entailing the risk of tangles and tangles, and without significantly increasing the frequency of failure of side walls in the drum winch

One therefore also immediately understands that there is a long-felt and urgent need within the industry for a high-strength synthetic rope that can be used without problems in connection with power blocks, where this high-strength synthetic rope exhibits a surface friction against a steel and/or iron surface when it is exposed for wet and/or greasy conditions, where this surface friction is at least greater than the surface friction currently exhibited by known high-strength synthetic ropes in such conditions and where preferably this surface friction is equivalent to or greater than the surface friction of steel and/or iron in such wet conditions and/or greasy conditions.

Published International PCT (Patent Cooperation Treaty) Publication WO 2004/020732 A2, International Application Number PCT/IS2003/000025, discloses a cable having a thermoplastic core within a braided synthetic strength element. The cable is a heat-stretched cable that is ultra-compact and effective in high-traction power block applications. In one embodiment, a cable is shown where the material of the thermoplastic core is in contact with both the synthetic reinforcement element and a braided synthetic sheath formed around the outside of the reinforcement element. However, this embodiment has not been generally accepted for the reasons stated above, i.e. due to the fact that the strength of the cable is reduced by such a construction.

In all embodiments, it is taught that heat stretching and compaction of the cable is done either by simultaneously heating and stretching with a tensile load the combination of the strengthening element, the thermoplastic core and a second sheath formed around the thermoplastic core and also contained within the strengthening element, where the purpose of this second sheath is to prevent uncontrolled flow of molten phase of the thermoplastic core during treatment of the rope, or by first applying the heat and then applying the tensile load. This cable has achieved more mainstream acceptance than any other synthetic rope for use with high-traction power blocks, and is the only viable synthetic rope in the prior art for use with high-traction power blocks, such as trawl winches for purposes such as trawl warps, and this cable and the processes shown for the production of this represent both the latest technology and the trend within the industry.

PCT/IS2010/000012 (publication WO 2011/027367) discloses a method and an embodiment of forming a high-strength synthetic rope for power blocks, said method and embodiment including attaching an outer braided sheath to a strength element by means of a highly elastic substance, such as a two-component polyurethane composition, and includes forming a layer of such substance around the outer surface of the braided jacket. This solution provides very low surface friction in wet and/or greasy conditions, especially in marine environments.

Description

None of the known techniques show a method for or the production of a synthetic rope containing a strength element with high tensile force which is shown by the present invention.

It is an object of the present invention to provide a rope containing a high-strength synthetic strength element for use with power blocks which meets the long-felt needs in the industry indicated above.

It is an object of the present invention to provide a high-strength synthetic rope which can be used without problems in connection with power blocks, while at the same time presenting a reduced risk of vases and tangles compared to known synthetic ropes, and which at the same time significantly reduces the frequency of failure of side walls in drum winches compared with the frequency of failure of such drum winch sidewalls when drum winches are used with known synthetic ropes.

It is another object of the present invention to provide a high-strength synthetic rope which can be used without problems in connection with power blocks, where this high-strength synthetic rope exhibits a surface friction against a steel and/or iron surface when it is exposed to wet and/or greasy conditions , where this surface friction is in any case greater than the surface friction currently exhibited by known high-strength synthetic ropes in such conditions, and where preferably the surface friction is similar to or greater than the surface friction of steel and/or iron in such wet and/or greasy conditions.

A method is described for producing a rope containing a high-strength synthetic strength element that can be used with power blocks, where said rope has a lower weight and the same or higher strength than a rope containing steel wire strength elements used with power blocks, while at the same time exhibiting an equal or greater friction against a steel and/or iron surface in wet and/or greasy conditions compared to a surface friction exhibited by steel wire in such conditions. A product resulting from this method is also described.

Most generally, the product includes a synthetic strength member, a first synthetic portion that is placed between a braided sheath and the strength member and adheres the braided sheath to the exterior surface of the strength member, a second synthetic portion located outside the braided sheath and affixed to the exterior surface of the braided sheath, portions of material attached to the second synthetic portion and projecting from the outer surface of the second synthetic portion and from the outer surface of the rope, where the portions of material attached to the second synthetic portion are formed of a material which: a) is distinct from a substance which essentially forms the second synthetic portion located outside the braided mantle (ie the second

synthetic share);

b) has a different hardness than the substance which mainly forms the synthetic part placed outside the braided mantle (i.e. the other

synthetic share);

c) has higher friction when it is wet and/or in greasy environments than the substance that mainly forms the synthetic part placed outside it

the braided mantle (ie the second synthetic portion); and

d) may have a different affinity for water, and may have a greater affinity for water and in some cases a lower affinity for water than the substance that mainly forms

the synthetic portion placed outside the braided sheath (ie the second synthetic portion).

Portions of leather, such as portions of rawhide produced by grinding up dry rawhide, are currently preferred for use as the portions of material adhered to and projecting from the outer surface of the second synthetic portion, and likewise portions of rubber, such as rubber parts produced by grinding up tires.

Preferably, the elasticity of the first and second synthetic portions is within an elasticity range of from twenty percent (20%) to five hundred and fifty percent (550%) measured at any temperature, with within two (2) degrees C of zero (0) degrees C preferred.

In a most preferred embodiment, a further synthetic substance is placed inside the interior of the strength element and the strength element is a hollow, braided strength element which was formed around this further synthetic substance when said further synthetic substance was a solid core of a thermoplastic material, and after forming the reinforcing member around said solid core of thermoplastic material, the combination of the thermoplastic core and the reinforcing member was subjected to sufficient heat to enable flow of the thermoplastic core and was also subjected to sufficient tensile stress to permanently elongate the reinforcing member and fibers forming the reinforcing member, followed by cooling the combination of the reinforcing member and the thermoplastic core while under tensile loading until cooling is complete, followed by the adhesion of the braided jacket to the reinforcing member with the first synthetic portion, followed by the application of the second synthetic the portion on the outer surface of the braided jacket, where: a) The material portions formed by a substance different from the substance forming the second synthetic portion is incorporated into the second synthetic portion before applying it to the outer surface of the braided jacket; and/or b) The portions of material formed from a substance different from the substance forming the second synthetic portion are brought into contact with the second synthetic portion after placement of the second synthetic portion around the outer surface of the braided sheath, which may be done for for example by blowing, dropping or pressing down on the surface of the second synthetic portion said material portions formed from a substance that is different from the substance that forms the second synthetic portion.

The preferred dimensions of the material portions formed from a substance different from the substance forming the other synthetic portion are about one-half (0.5) millimeter in a granular form, and also one-half (0.5) millimeter if a fiber or filament form is used.

In order to adhere the material parts formed by a substance different from the substance forming the second synthetic part to the second synthetic part and thus to the outer surface of the rope: a press stamp or a roller stamp is preferably used to smooth the second synthetic part including the material parts formed from a substance different from the substance forming the second synthetic part into a uniform shape around the outer surface of the braided sheath after either: a) placing in contact with the second synthetic part, the material parts formed from a substance different from the substance which

forms the second synthetic portion; or

b) applying to the outer surface of the braided mantle, while in a liquid or semi-liquid state, a mixture formed by a

combination of the substance forming the second synthetic part with the material parts formed from a substance different from the substance forming the second synthetic part.

Alternatively, the second synthetic portion may first be brought into contact with the outer surface of the braided mantle and then smoothed to a desired or uniform shape using a press die, the material portions being formed of a substance different from the substance forming the second synthetic the portion may then be brought into contact with the second synthetic portion, to which they permanently adhere after curing (including "drying") of the substance forming the second synthetic portion.

In the most preferred embodiment of the present invention, it is

the braided sheath formed with a design and structure that prevents cord members forming the braided sheath from carrying a proportional load (including tensile stress) compared to the majority of cord members forming the strength member, so that the cord members forming the braided sheath carry a smaller load relative to their breaking strength compared to most of the cord sections forming the strength element, and preferably compared to all the cord sections forming the strength element, when the rope is loaded to at least ten percent (10%) of its maximum load-carrying capacity (ie, its "breaking load"). One embodiment of a sheath for the rope according to the present invention which fulfills this important requirement is a braided cover formed from cord parts of synthetic material where the cord parts forming the braided cover have a lower pitch than the majority of the cord parts forming the strength element, and preferably have a lower pitch than all the cord parts that form the strength element. This design and structure of a high tensile synthetic rope provides optimal friction and traction when used as the braided sheath for the rope of the present invention, and is contrary to the state of the art and the trend in the industry of exterior design and construction the wire layer for a rope with high tensile strength.

An advantage of the described synthetic rope with high tensile force for power blocks is that it allows reduced sidewall dimensions in drum winches, and thus makes it possible to reduce costs for machines and superstructures and associated costs for floating mooring and/or anchor lines necessary to anchor derricks, especially deep-water oil rigs and other floating structures, and trawling vessels.

Another advantage of the described high tensile strength synthetic rope for power blocks is that it enables much higher safety for persons in and around the area of the rope during handling and use of the rope.

Yet another advantage of the described high tensile synthetic rope for power blocks is that it reduces downtime and lowers operating costs, and reduces the initial cost of equipment acquisition as it does not require as strong sidewalls on drum winches, for example.

Yet another advantage of the described high tensile strength synthetic rope for power blocks is that, as a result of its increased tensile strength, it requires less handling time to perform many tasks.

Yet another advantage of the described synthetic rope for power blocks is that, as a result of its increased traction, it improves the predictability of operational events and reduces operational risk.

With the above advantages, the described synthetic rope with high tensile strength for power blocks meets a long-felt need in the industry.

It will be readily appreciated that these and other features, purposes and advantages will be understood by or apparent to those skilled in the art from the following detailed description of the preferred embodiment, as illustrated in the various figures of the drawings.

Brief description of the figures

Figure 1 is a plan view of a portion of a rope according to the present invention. Figure 2 is a cross-section through the rope according to the present invention taken along the line A-A in Figure 1. Figure 3 is an enlarged detailed view of a portion of the cross-section through the rope according to the present invention shown in Figure 2, denoted by reference B. The enlarged detailed view includes a braided sheath on the rope according to the present invention, a part of the strength element in the rope according to the present invention, where this part of the strength element is located close to the braided sheath, and associated structures.

Best way to realize the invention:

Figure 1 illustrates a plan view of a part of the high tensile synthetic rope according to the present invention which is indicated by the general reference number 1. As shown, the rope 1 includes a second synthetic part 21 with several material parts formed of a substance different from the substance which forms the second synthetic part, denoted by the reference number 23, which projects from the outer surface of the second synthetic part and thus projects from the outer surface of the rope 1. Figure 2 and Figure 3 illustrate important structural components in one of the most preferred embodiments , for use with power blocks with high traction, of the rope for power blocks and winches according to the present invention which is indicated by the general reference symbol 1. Figure 2 shows a preferably thermoplastic profiled support core 3 surrounding a lead core 2, where the profiled support core 3 is encased within a flow screening mantle 5. The strength element 7 surrounds the combina tion of the shaped support core 3, its enveloping flow shield jacket 5 and its lead core 2. A jacket 8 preferably has a braided design and is attached to the strength element 7 by an elastic adhesive layer 9 (which forms the first synthetic part), which is preferably formed by a hardenable adhesive. Preferably, the braided mantle 8 is formed from several interbraided (coverbraid) cord parts 10 using a braiding machine, where the interbraided cord parts 10 preferably have a twisted design. Optionally, and preferably, as seen in more detail in Figure 3, a cavity-filling layer 13 of elastic adhesive material fills indentations in the surface of the rope 1 formed between adjacent interlaced cord sections 10. The second synthetic portion 21 is formed around the outer surface of the braided mantle 8, preferably using the same substance that was used to form the first synthetic portion. The material portions 23 formed of a substance different from the substance forming the second synthetic portion are attached to the second synthetic portion, and they are both contained within the second synthetic portion and protrude from the outer surface of the second synthetic portion. The thickness of the second synthetic portion 21 is the minimum thickness necessary to adhere the material portions to the outer surface of the braided jacket, and can be from about half a millimeter to one millimeter, depending on the dimensions of the material portions, which can be from a quarter of a millimeter to half a millimetre, or one millimeter or more, depending on what is optimally found through experiments. The coverage of the outer surface of the rope with the material proportions is preferably from at least ten percent to up to ninety percent, and is more preferably at least twenty percent, but may be more, depending on what is optimally found through experiments for a particular combination of materials forming it other synthetic shares and material shares 23.

The lead core 2 is optional, and is preferred for trawl warp applications and in certain other applications, but not necessarily for anchor lines and mooring and/or anchoring lines for deep-water drilling rigs or lines for boats, although in some cases it may also be incorporated in such applications. Instead of a lead core 2, a core of conductors capable of transmitting electrical energy and/or light energy, data and power may be useful. In such embodiments, the conductors are initially slack when the reinforcing member is formed around the thermoplastic core, and are then stretched under permanent elongation of the reinforcing member, but not stretched so much and/or far as to cause breakage or damage to the conductors.

The present invention thus shows a synthetic rope exhibiting improved tensile strength comprising a strength element formed mainly of fibers, a braided jacket formed mainly of fibers, a first synthetic part which adheres the braided jacket to the outer surface of the strength element, a second synthetic part which is placed on the outer surface of the braided mantle and adheres material portions formed by a substance different from a substance that mainly forms the second synthetic portion, wherein the material portions formed by a substance different from the substance that mainly forms the second synthetic portion exhibits different features compared to a substance which mainly forms the second synthetic portion, the different features being selected from the group consisting of: a) different hardness; b) the material shares show a greater affinity for water than is presented

of the substance that forms and/or mainly forms the other synthetic

the proportion;

c) the material parts exhibit a different elasticity than that exhibited by the substance that forms and/or mainly forms the other synthetic

the proportion;

d) the material portions exhibit a different elasticity, and preferably a lower elasticity, at a temperature which is approximately zero degrees Celsius than that which

is presented by the substance that forms and/or mainly forms the second synthetic part; and

e) the material fractions exhibit greater friction when wet and measured on an iron surface than that exhibited by the substance which forms and/or which

mainly forms the second synthetic portion.

Clearly the most important of these different features is that the material portions exhibit greater friction when wet and measured on an iron surface compared to a friction exhibited by the other synthetic portion when wet and measured on an iron surface.

The present description provides several examples of methods according to the present invention for producing a synthetic rope with a high tensile force according to the present invention: Example A: The present invention shows a method for producing a synthetic rope (1) that exhibits improved tensile strength, the method comprising steps of to: first, form a strength element (7); secondly, applying an adhesive forming a first synthetic portion (9) around the outer surface of the reinforcing member; third, forming a braided sheath (8) around the combination of the reinforcing member and the adhesive forming the first synthetic portion; fourth, adhere to the outer surface of the braided mantle, by means of a second adhesive forming a second synthetic portion (21), material portions formed of a substance different from a substance that mainly forms the second synthetic portion, the method including the step of selecting as the material fractions formed by a substance different from the substance that mainly forms the second synthetic fraction a substance that exhibits different features compared to a substance that mainly forms the second synthetic fraction, and selecting the different features from a group consisting of of: a) different hardness; b) a greater affinity to water is exhibited by the material portions than that exhibited by the substance which mainly forms the second synthetic portion;

and

c) greater friction when wet and measured on an iron surface is exhibited by the material proportions than that exhibited by the substance which is mainly

forms the second synthetic portion.

the iron surface, thereby providing a synthetic rope containing a strength element which has a low weight compared to steel wire rope and a poorer ability to store kinetic energy compared to steel wire rope and at the same time also increase the tensile force of the synthetic rope containing the strength element and improve its operational reliability and its operating economy .

to store kinetic energy compared to steel wire rope and at the same time also increase the tensile force of the rope containing the synthetic strength element and improve its operational reliability and its operational economy.

The above methods of forming the high tensile synthetic rope of the present invention may include the step of spraying or dropping or injecting or extruding non-solid material portions onto the surface of the second synthetic portion during either the non-solid or the cured phase of the second the synthetic portion, wherein the non-solid material portions brought into contact with the surface of the second synthetic portion harden to the material portions (23);

The methods of the present invention may further include steps of selecting a treatment from the group consisting of: plasma treatment; electric arc treatment; sputtering; and corona treatment, to facilitate the attachment to each other of a hardened phase of any of the synthetic substances incorporated in the rope or to the attachment of any of the elements incorporated in the rope to any other element forming the rope, e.g. for fixing the material parts (23) to the second synthetic part and most preferably to a hardened phase of the second synthetic part.

Preferred manufacturing methods

There are two preferred embodiments of the present invention: one is a rope according to the present invention for use for purposes where the rope according to the present invention is subject to storage under high compression pressure, for example when used with winches and drums with high traction, for example when using as a trawl warp; another is where the rope according to the present invention is not subject to storage under high compression pressure, which is, for example, common in many sailing-related applications - the main difference between the two preferred embodiments is the choice of design and features for the strength element and what it contains: Manufacture of a preferred embodiment of the present invention for use in applications where the rope according to the present invention is subject to storage under high compression pressure: First, a strength element formed from synthetic fibers including polyethylene, especially HMWPE, UHMWPE and liquid crystal polymer (LCP) is provided. The reinforcing element can be parallel-stranded, twisted (including twisted) or braided. A braided strength element having several cord sections formed from twisted (plied) fibers is the preferred embodiment. For example, a braided strength element is preferred which has at least eight plates, preferably ten cord sections, more preferably twelve cord sections, even more preferably 14 cord sections and even more preferably from 16 cord sections to 108 cord sections or even more, depending on what the diameter of the rope requires. Any traditional type of design of a braided reinforcing element can be used. However, it is highly preferred and important for a preferred embodiment of the present invention that a braided strength element is selected which has a thermoplastic core designed to support the natural internal shape of the braided strength element under tensile loading approaching the breaking strength of the strength element. As a reinforcing element, a braided reinforcing element is preferably provided where the fibers forming the reinforcing element are crimped after the fibers are braided into the reinforcing element, rather than before interlacing the fibers in the reinforcing element, and where the resulting reinforcing element is not capable of more than 5% elongation before it reaches the breaking point, measured at an initial tensile force of 1000 kg, and preferably such that the resulting strength member is not capable of more than 4% elongation before reaching the breaking point, measured at an initial tensile force of 1000 kg, and even more preferably is not capable to more than 3.6% elongation before reaching the breaking point, measured at an initial tensile force of 1000 kg.

In the manufacture of a strength element for the preferred embodiment of the present invention, the following steps are performed: First, fibers capable of creep are selected as indicated above and herein.

Second, a thermoplastic linear element is provided which is substantially formed with a thermoplasticity which shall be capable of exhibiting a flowable state (ie shall be in a liquid state, but more preferably shall be semi-liquid, ie in a molten phase) when this thermoplastic is at a temperature which is a temperature more than eight degrees C lower than a temperature at which the selected fibers undergo a phase change, and more preferably at least ten degrees lower, even more preferably at least fifteen degrees lower and even more preferably at least nineteen degrees lower than the temperature at which the selected fibers undergo a phase change, which goes in the opposite direction of the latest technique and against the trend in the industry and surprisingly results in an unexpected increase in the strength of the final formed rope.

The thermoplastic linear element is preferably a rod formed of thermoplastic ("formed of thermoplastic" shall be understood to include formed of a sufficient proportion of thermoplastic to enable the linear element to pass through the semi-fluid, i.e. molten, phase under the conditions indicated above and herein, although other substances may be incorporated with the thermoplastic, or lead or other metals or heavy plastics may be incorporated in a linear arrangement in the center of the thermoplastic linear element, which is preferably a rod, to increase the weight in water to the final rope product according to the present invention).

Third, a flow barrier jacket is formed around the thermoplastic rod. Any jacket design that substantially prevents liquid and semi-liquid phases of the thermoplastic core from escaping through the walls of the flow jacket may also be used to form the flow barrier jacket. In a currently preferred embodiment, a tightly woven braided flow barrier jacket is braided around the thermoplastic rod. Fibers are selected so as to form a flow barrier mantle that does not become either liquid or semi-liquid at a temperature chosen to creep the fibers and/or change the phase of either the fibers or the thermoplastic rod, but instead has a much higher softening point. Polyester is suitable.

Fourth, when it is chosen to form the flow barrier jacket with a braided structure, the selected fibers are braided around the linear member formed by a thermoplastic and its flow barrier jacket, such as a thermoplastic rod surrounded by a flow barrier jacket, to form a braided strength member including a thermoplastic core surrounded by a flow barrier jacket.

Fifth, the braided reinforcing member with the thermoplastic rod surrounded by the flow barrier jacket as its core is then subjected first to tensile loading and then to heat, while the tensile loading is maintained, in a manner and under conditions that permit permanent elongation of the fibers forming the reinforcement member and permit permanent elongation of the strength element itself. A thermoplastic is selected to form the thermoplastic core which preferably becomes semi-fluid, i.e. melts, at the temperature used to permanently extend the fibers and the braided strength element formed by the fibers. The flow barrier jacket substantially or completely prevents the phase-changed thermoplastic core from leaving the flow barrier jacket. Specifically, the bulk of the thermoplastic core is unable to leave the flow barrier jacket even when the thermoplastic core is either liquid or semi-liquid, i.e. molten, despite the enormous compressive and compressive forces applied to the phase-changed thermoplastic core as a result of the high tensile load applied to the reinforcing member, a tensile load large enough to permanently elongate the reinforcing member under the conditions set forth above and herein.

Application of tensile load prior to application of the heat at a temperature not within 8 degrees C of a temperature at which the fibers forming the main synthetic strength element undergo a phase change, and which is also a temperature which, when the rope is stretched, is a temperature sufficient to to cause permanent elongation of both the reinforcing element and the fibers that primarily form the reinforcing element, while then maintaining the tensile load while the heat is applied, is important, and goes against the state of the art and against the industry trend.

A preferred tensile load for use in the described processes to form the described rope is from about eight percent (8%) to about seventy percent (70%) of the breaking strength of the reinforcing member when this breaking strength is measured at room temperature, with from about three percent (3% ) to about thirty-seven percent (37%) is preferred and less than fifty-five percent (55%) is most preferred. However, when the rope of the present invention is formed without the shaped support core formed with the use and incorporation of the thermoplastic linear element in the manufacture of the rope of the present invention, temperatures approximately room temperature and the preferred tensile load are selected for use in the described processes to produce it described rope is from approximately sixty to seventy percent (60% to 70%) of the breaking strength of the strength element, when this breaking strength is measured at room temperature.

An important point is that the tensile load applied to the strength element, and thus necessarily also applied to the fibers forming the strength element, is preferably a static tensile load and/or a mainly static tensile load and/or a very slowly varying tensile load. After application of a predetermined tensile load (including approximately a predetermined tensile load), and while under the influence of such predetermined tensile load, the reinforcing member, its fibers and its thermoplastic core are simultaneously heated to a predetermined temperature and/or approximately to a predetermined temperature which stated above and herein, and, contrary to the state of the art and against the trend in the industry, a temperature that does not approach the phase change temperature of the fibers and/or type of fiber that mainly forms the strength element, i.e. is not within eight degrees C of this phase change temperature, and more preferably is at least ten degrees lower, even more preferably at least fifteen degrees lower and even more preferably at least nineteen degrees lower than the temperature at which the selected fibers undergo phase change, which goes in the opposite direction of the latest technology and against the trend in the industry, which surprisingly results in an unexpected increase in strength n to the finally formed rope. Use of a long furnace with many aisles capable of accommodating a very long length of the reinforcing member and rotating at varying speeds and/or rotational speeds to maintain the tensile load on different portions of the reinforcing member located between different aisles, and thus on the fibers forming the reinforcing member and on the thermoplastic core which also forms the strength element is highly advantageous, especially to enable a continuous production process.

Sixth, when the fibers and thus the braided strength member is elongated a predetermined amount to enable a strength member having the properties described above and herein, and in particular having an elongation at break within the range of values stated above and herein, and also the thermoplastic core is extended, the elongated fibers, the now elongated reinforcing element formed by the elongating fibers and its elongated thermoplastic core are cooled while sufficient tensile stress is maintained and applied to the reinforcing element and thus to its fibers and to its thermoplastic core during the cooling process so that all these components are cooled to their respective solid states with they are under a tensile load which results in the cooled fibers and the cooled reinforcing element being both: I) permanently compacted so that the manufactured reinforcing element according to the present invention exhibits less lateral deformation when subjected to a given tensile load and when brought against a hard working surface on a traction winch and/or drum winch than that exhibited under such same circumstances by a known wire rope, which result and pull differs from the state of the art and is against the trend of the industry and against the prevailing belief in the industry , and;

II) permanently extended and such that the strength element:

a) achieves less extension than if it had been permanently extended; b) achieves a significantly smaller diameter and greater compactness than it had before it was permanently elongated; c) achieves in its thermoplastic core a permanently fixed shape which supports the internal cavity of the permanently extended reinforcing member in such a way that the fibers and the braided cord portions forming the reinforcing member are sufficiently less able to move relative to each other in the direction perpendicular to the longitudinal direction of the permanently extended strength element compared to before the strength element was permanently extended to reduce abrasive wear between fibers and also to prevent pinching or crushing of the rope, especially under high compressive forces such as occur during winding and storage on a drum with high tensile strength, as mentioned above, the tensile load required to achieve this result for any given fiber type can be determined experimentally by one skilled in the art after reading the present disclosure; and also d) achieves a break limit that is within the range of values for elongation at break as set forth above and herein.

This cooling is also best achieved and carried out by means of gear wheels rotating at varying speeds to maintain a tensile load on the elongated strength member and its components throughout the cooling process and period which prevents them from shortening so that the final chilled strength member has elongations at break which indicated above and herein for a most preferred embodiment of the present invention, and also the other properties indicated above and herein, which can also be achieved in a continuous production method.

To produce a rope according to the present invention which cannot be used for purposes requiring resistance to high compression pressures, for example applications which do not include a trawl warp, and other applications which do not include storing the rope according to the present invention on drums and winches with high traction force, the step of forming the thermoplastic rod with its flow barrier jacket may be omitted and the subsequent steps are performed as indicated above and herein except that the thermoplastic rod and its flow barrier jacket are not present and their properties therefore need not be considered. When manufacturing the rope according to the present invention without the shaped support core which is formed through the use and incorporation of the thermoplastic linear element in the manufacture of the rope according to the present invention, however, temperatures are chosen which are too low to allow a change of the phase of the fibers which mainly form the strength element and the preferred tensile load for use in the described processes for making the described rope is from about fifty to seventy percent (50% to 70%) of the breaking strength of the reinforcing member when this breaking strength is measured at room temperature.

After the selected strength element in the rope according to the present invention has now been formed, the remaining production steps, as already described here and above, are carried out to produce the preferred selected synthetic rope containing a strength element with high tensile force according to the present invention.

the selected fibers undergo a phase change, which goes against the state of the art and against the industry trend, surprisingly resulting in an unexpected increase in the strength of the final rope);

forming a flow barrier jacket around the thermoplastic rod;

subjecting the braided reinforcing member formed around the thermoplastic rod surrounded by the flow barrier jacket first to tensile loading and then to heat, while maintaining the tensile loading, in a manner and under conditions that permit permanent elongation of both the fibers forming the reinforcing member and the reinforcing member itself;

select for the heat a temperature which is not within 8 degrees C of a temperature at which the fibers which mainly form the synthetic strength element undergo a phase change and which is also a temperature which, when the rope is stretched, is a temperature sufficient to cause permanent elongation of both the reinforcing element and the fibers that mainly form the reinforcing element;

cooling the reinforcing member elongated by a predetermined amount and the thermoplastic core while maintaining sufficient tensile stress applied to the reinforcing member during the cooling process such that at least both the reinforcing member and the thermoplastic core are cooled to their respective solid states while under a tensile load resulting in the cooled fibers and the cooled reinforcing element are permanently compacted, so that the manufactured reinforcing element of the present invention exhibits less lateral deformation when subjected to a given tensile load and when brought against a hard working surface by a traction winch and/or drum winch than that which is exhibited in such same circumstances by a known steel wire rope.
