Description

The present invention relates to a cord with a jacketed core according to claim 1.

US Patent No. 4,640,178 discloses a cord with jacketed core which brings together a large number of bundles of core fibers, as a core, and which is surrounded by an intermediate lining. Around the intermediate lining is a braided lining made of monofilament threads located in the Exterior. The core, the intermediate liner and the liner are not connected to each other and slide along it. reason for each other, which proves to be disadvantageous during the use of the core rope jacketed

According to US Patent No. 4,170,076 a cord with a jacketed core is known which consists of a core braided which, in turn, is formed by a large number of core fiber bundles. The core is surrounded by a braided lining. The core and the lining are not connected to each other and are not therefore anti-slip. Thickening or thin points are formed during use, which is disadvantageous.

According to WO 03/027383, a rope type structure is known, especially core strings jacketed, ropes or ropes in which the individual fibers, threads and strands of wire are connected each other in such a way, that these are present in a non-slip way with each other. The rope-like structures of this type has an increased resistance in terms of its expansion behavior and a resistance of increased knot

From document AT 3583433 a rope is known, in particular a climbing rope, with a construction of core lining, in which the lining threads are guided such that they are located colored out as a braiding sample formation or that, for a better clamping of the lining, They are located in the core. The core threads are held by hose braids.

In addition ropes with a core and a lining or cords are known which are usually twisted or manufactured from different braided sections, such as hollow braid without a core or from sections. Thanks to in this way, ties at one end, the so-called "splices" can be formed in ropes of this type. These properties They are appreciated and used especially in the sport of sailing. The splice is, however, complex and therefore expensive.

The present invention poses the problem of proposing a cord with a jacketed core, in which the fibers, individual strands or strands of yarn are connected as lingual-lingual fibers in such a way that the fibers, threads or sections of thread are non-slip to each other, thereby eliminating the aforementioned inconveniences.

The problem is solved according to the invention with a cord with a jacketed core according to claim 1.

The invention is explained in greater detail in the following from the figures, in which:

Fig. 1 shows the schematic structure of a cord with jacketed core according to the invention, Fig. 2 shows a first exemplary embodiment of a cord with a jacketed core with a intermediate lining and other transversely located fibers, Fig. 3 shows a second exemplary embodiment of a cord with jacketed core made with the same materials and with a different thickness and strength, Fig. 4 shows the schematic structure of a rope with little extensible jacketed core, Fig. 5 shows a third exemplary embodiment of a cord with jacketed core with good damping properties, Fig. 6 shows a cord with a jacketed core with an inscription, Fig. 7 shows a cord with a jacketed core with a continuous designation, Fig. 8 shows the schematic structure of a rope for operating candles, Fig. 9 shows a cord with a jacketed core with a hollow space, Fig. 10 shows a cord with jacketed core with a modification of the cross section

Fig. 1 shows the schematic structure of a cord with jacketed core according to the invention.

A cord with jacketed core 10 has an inner core zone 1 and a cladding zone 2 that the surrounds. An intermediate liner 8 is located between the inner core zone 1 and the cladding zone 2. core zone 1 consists of at least one core 3, which in turn is formed by a large number of fibers, threads, sections of thread and / or at least by a string, and which are then referred to jointly as the called core fiber structure 5. The coating area 2 consists of a coating 4 which, by its part, is formed by a large number of fibers, threads, sections of thread and / or at least one other string, and that in what

it comes next to designate, together, as so-called structure of cladding fibers 6. In the area of the core 1 there may also be several cores, for example three or five, provided with core fibers and / or cords of the same type or different types, thereby indicating the diversity of shapes of the core fiber structure 5. Something similar is also valid for the structure of sheathing fibers 6.

The core fiber structures 5 and the coating fiber structures 6 are constituted by long fibers and meet in what follows as long fiber structures 40.

A part of the core fiber structure 5, designated as core fibers 5 ', is present in the cladding zone 2 and is connected therein with the cladding fibers of the cladding fiber structure 6, while a portion of the lining fiber structure 6, designated as lining fibers 6 ', is connected in the core area 1 and in this one with the core fibers 3. Thanks to this the lining is arranged, on at least one core , in a mutually non-slip way. Several coatings with different fibers can also be connected in a non-slip manner with the at least one core of mutually anti-slip shape. At least one additional fiber 50, arranged transversely with respect to the structure of longitudinal fibers 40, or a bundle of fibers, keeps the longitudinal fibers non-slip with respect to each other or against each other in the structure of longitudinal fibers 40. In What comes next is always understood by the designation of "fiber 50" also a bundle of fibers.

The fiber 50 is located, with respect to the structure of longitudinal fibers 40, essentially transversely diagonally with respect to the longitudinal fibers or runs at an angle, almost discretionary, with respect to these, as a rule however forming an angle which measures less than 45º. It can also be an angle between 45º and 90º or exactly 90º. More special arrangements of fiber 50 are described later.

The slip of the lining on the core is a known, although highly unwanted, property in the strings with jacketed core - as already explained. The described structure, on the one hand with a mixture of core and cladding fibers and, on the other, by means of cross-linked fibers, prevents any slippage and therefore offers essential advantages.

Advantageously, it is a uniform step when passing through carabiners, rollers and unwinding devices. There are no thickening or thinning points, as usual in the case of coating slipping. Ropes with a jacketed core of this type can be used instead of twisted ropes.

As fibers, materials such as PBO, polyolefin, polyamide, polyester, Dyneema, aramid, Vectran and Zylon are taken into account for high strength uses, aramid, Nomex and monofilament threads for heat resistant and anti-inflammable uses, polypropylene, polyamide, polyester and monofilament threads for those resistant to UV irradiation, polypropylene and monofilament threads for floats, and polyamide, polyester and monofilament threads for cutting and shear resistant uses.

The bundles of transverse located fibers consist of monofilaments, multifilaments or short fibers. They are twisted, twisted or made as bundles of parallel fibers. Mixed fibers of different fibers are also used. Any combination of individual fibers is imaginable.

The primary function of fiber 50, or of the fiber bundle, is this bonding process. Obviously, the fiber mass is conducted after the "binding" to the next place of binding, for which the fiber generally runs parallel to the longitudinal fibers, which is equivalent to a "displacement" of the binding points. This subsequent conduction of the fiber 50 is a secondary function, which is why the designation "essentially transverse located" seems appropriate. With this one or more fiber (s) 50 a surface with a different appearance is formed or obtained. The sections of yarn and individual fibers used for this, which may have a different thickness, strength and color, are almost immovably connected with the longitudinal fibers of the longitudinal fiber structure 40.

Fig. 2 shows a first exemplary embodiment of a cord with jacketed core with an intermediate sheath and additional fibers located transversely.

The core 3 has high performance fibers in the core fiber structure 5 with fibers such as polyamide (PA), polyester (PES), extensible polyester (PEN), aramid, Dyneema, Vectran or Zylon. The intermediate lining 8 consists of so-called cushioning threads such as, e.g. ex. monofilament or elastic threads, which have a high compression property, while the lining 4 consists of lining fibers in the lining fiber structure 6, such as polyester or polyamide, which have a high wear resistance, when cutting or singing.

The high performance fibers of the core fiber structure 5 and the cladding fibers of the cladding fiber structure 6, also designated as longitudinal fibers 40 of the longitudinal fiber structure 50, are surrounded, or wrapped, to a large extent by fibers 50 located approximately transversely, surrounding some of the fibers 51, located jointly outside, the longitudinal fibers, while other fibers 51 'surround the longitudinal fibers only alternately, that is to say only one of every two longitudinal fibers located Outside is tied. As fibers 51, 51 ’, polyamide was used.

When said at least one additional fiber 50 has a greater resistance against the longitudinal fibers of the longitudinal fiber structure 40 and surrounds and ties the longitudinal fibers differently, a cord with a jacketed core is formed with greater flexibility and strength and , thanks to this, with greater rigidity.

If the core consists, for example, of highly resistant aramid fibers and the coating, or in any case the various coatings, are made of heat-resistant Nomex fibers, then the cord with jacketed core is especially suitable for rescues as a heat-resistant rope in the field of firefighters and the army.

The mixture, or connection, of core fibers in at least one core zone may be small, that is, less than 3%. At the same time, there does not have to be a mixture of coating fibers in the core zone. However, if this happens, we also talk about a small mixture, that is, it is worth less than 3%. The core fibers are then present in at least one coating zone, while the coating fibers are connected in the core zone. This refers above all to dynamic and static jacketed string applications used today.

Fig. 3 shows a second exemplary embodiment of a cord with jacketed core made of the same materials with a different thickness and strength. A cord with a jacketed core has longitudinal fibers, the fibers located outside being thicker than the core fibers. The cladding fibers located outside are alternately bonded with the additional fiber 50. Thanks to this, a greater resistance is formed in the coating area. The cord with a jacketed core can also have a surface that is similar to that of a twisted rope.

The core and coating fibers are made of polyester and the transversely arranged fibers are made of polyamide.

The longitudinal fibers of the longitudinal fiber structure 40 are located, in general, mixed as core and cladding fibers, the cladding fibers forming a part of the core and the core fibers a part of the cladding. They are linked at the same time by at least one additional fiber 50 with a greater resistance with respect to the longitudinal fibers, the additional fiber having a different thickness, strength or extensibility.

Fig. 4 shows the schematic structure of a rope with extensible jacketed core. A cord with a jacketed core consists of individual fibers, threads or sections of yarn as longitudinal fibers of the longitudinal fiber structure 40, which are connected in such a way to each other, or are present, that the fibers, threads or sections of yarn are mutually anti-slip. At least one additional fiber 50, located transversely or transversely running, or a bundle of fibers, always binds the longitudinal fibers, whereby the longitudinal fibers are mutually non-slip, or in a fixed position. As for its appearance, it appears to a twisted or braided rope, although it has a resistance that is at least 10% greater in terms of its extension behavior and a knot resistance of at least 10% greater compared to the ropes. conventional. A positive property is that at the cut end it does not fray or destort. In this rope construction, many threads are as parallel as possible or are stretched or pre-stretched additionally.

In these uses the fibers must be located in the core area in an extremely parallel manner and are partially pre-stretched, while the fibers in the coating area are arranged surrounding and therefore are more flexible, resistant to wear and tear and also increase notably the resistance to UV radiation.

If said at least one additional fiber 50 has, with respect to the longitudinal fibers of the longitudinal fiber structure 40, greater elasticity and if it binds the longitudinal fibers, then it results for a core of highly resistant aramid fibers and in a coating of heat-resistant or wear-resistant Nomex fibers, cut-resistant and / or anti-inflammatory, fibers and / or threads resistant to fire, acid or UV radiation, a typical fireman's rope. Other typical uses are generally found in rescue actions such as ropes instead of steel cables, as a load carrying cable with small bending changes or as a substitute for twisted ropes.

If the core has, however, highly resistant fibers, which are pre-stretched or stretched, and if the coating consists of UV-resistant and wear-resistant yarns and / or fibers, typical properties are provided for ends for trigger candles.

Fig. 5 shows a third exemplary embodiment of a cord with jacketed core with special fall damping properties.

A cord with a jacketed core can, according to the invention, be manufactured in the most damping manner of the possible fall from threads, which consist of the largest possible number of fibrils and that form a string 20, the core fiber structure being surrounded multiple times with at least one additional fiber 50, or a fiber bundle. In this way, a large number of fibers 50, different in material and properties, can be used to surround one or more cords according to a discretionary sample.

These strings are used in the core of a cord with a jacketed core according to the invention. Thanks to the good damping properties this construction is preferably suitable for dynamic mountain ropes. Due to the good damping properties of the fall, polyamide, polyester or POY threads are preferably used here.

Fig. 6 shows a cord with a jacketed core with an inscription. In a longitudinal fiber structure 40, by means of at least one additional fiber 50, or a bundle of fibers, an inscription 52 has been included on the outer surface of the structure that runs in the longitudinal direction of the cord with a jacketed core. Good readability is essentially reinforced by a skillful choice of the color of the fiber 50 and / or the individual longitudinal fibers.

In addition to the inscription it can also be a designation of any kind and / or, for example, an indication of the center of the cord with a jacketed core. The inclusion can also take place in a transverse direction or at a discretionary angle with respect to the longitudinal direction of the cord with a jacketed core.

Fig. 7 shows a cord with a jacketed core with a continuous description. In a longitudinal fiber structure 40, by means of at least one additional fiber, a continuous designation 53 has been incorporated into the outer surface of the rope structure with jacketed core. This is, for example, an annular mark with consecutive numbering. The surfaces of the intervals 54 ', 54' 'between the designations have been characterized, as the designations 53, with a special choice of fibers 50, on the one hand, and, on the other, by the corresponding incorporation into the structure of the surfaces. Thus, for example, the surface of the 54 ’striped interval and that of the 54’ striped interval appears.

Such a structuring of the surface of the rope is advantageous and especially easy to use.

Fig. 8 shows the schematic structure of a rope for driving sails or an extremely static high performance rope. Ropes with jacketed core, in terms of their appearance similar to braided, crooked or similarly constructed or design strings, are manufactured in such a way, instead of the usual jacketed core constructions, with static high-performance ropes with the least extension It is possible that extremely high-strength high-performance fibers are located very parallel in the core and have an essentially reduced extension and greater strength, and thus improved static properties also for equal or reduced diameters. These longitudinal fibers of the longitudinal fiber structure 40 may be pre-extended or pre-stretched. The fibers of the coating can essentially give wear resistance, moisture insensitivity and shear resistance properties, the core 3 and the coating 4 being connected in such a way to each other by one or more wires running in another direction, or other fibers 50, that for the properties of different fibers no slippage of the coating or an additional extension can be formed.

Fig. 9 shows a cord with a jacketed core with a hollow space. A structure of longitudinal fibers 40 has 3 very high strength fibers in the core with a remarkably reduced extent and greater strength, which also give improved properties for equal or reduced diameters. These core fibers surround a hollow space 55 located in the center of the core. The longitudinal fibers of the core, the intermediate coating and the coating are connected to each other in such a way by at least one additional fiber 50 located transversely that, also in case of different fiber properties, no slip of the coating is formed. The intermediate coating consists of different fibers or of the same fiber as the core or the coating. Thanks to this, a soft flexible structure is formed, which allows the formation of a cushion pad, or an air cushion, under the lining and which, paired with the wear-resistant, edge-resistant, cut-resistant fibers and the fiber constructions of the cladding, presents an extremely improved edge resistance. The fiber structure of the inner lining has at the same time finely structured minimum hollow spaces, or minimal air bubbles. The hollow space 55 is also designated as "soft center point of the core". The construction according to the invention looks similar to that of braided ropes. A cord with a jacketed core of this type is especially cut resistant and is especially suitable for rescue operations of any kind.

Fig. 10 shows a cord with a jacketed core with a modification of the cross section. A cord with a jacketed core with an essentially round cross section 61 varies, during the manufacturing process, at least one discretionary point 62 the cross section 63 passing into an oval or flat shape. At this point the rope can be, for example, fastened more easily and better, sewn or imprisoned. Modifications of the cross section can take place once or several times. Thus, the oval shape can be transformed into a flat shape and, later, again into a round shape. The fibers 50, or bundles of fibers, located transversely link the longitudinal fibers in a multiple manner, so that the cord with a jacketed core appears to be surrounded as a network.

Strings with jacketed core of this type can be sewn and do not need to be spliced, which represents an essential simplification in the construction of the final connections.

According to the invention, ropes with jacketed core can also be manufactured whose appearance is similar to that of a twisted rope and which, in its core zone, consist of other extreme high-demand fibers such as highly resistant aramid fibers or Vectran, Zylon. The protective coating may consist of fibers and / or threads,

10 which form a protection with UV radiation or a coating especially resistant to wear. In the place of cutting the ropes with a jacketed core of this type can be sewn and do not need to be spliced. In addition, a cord with a jacketed core of this type is not dislodged at the cutting place. Structures of strings with jacketed core of this type are extremely diverse and cannot be conclusively listed here.

15 The strings with jacketed core according to the invention are used in safety at work, in water sports, in sailing and mountain sports, as well as in the police, firefighters and the army. Ropes with jacketed core according to the invention are used for free time and hobbies, preferably as substitutes for braided or twisted ropes.
