Definitions

  • This invention relates to flexible sleeves and more particularly to braided sleeves formed of materials including resilient monofilaments and more particularly relates to sleeves incorporating both the properties of radial expandability and compression inherent in a braided structure along with extended axial elongation provided by corrugations or flanges integrally moulded into the sleeves.
  • Substrates such as electrical wire or cable are frequently protected with braided sleeves formed of various materials, such as wire, for the purpose of providing electrical shielding or of abrasio resistant, thermoplastic materials- f r the-purpose o providing abrasion resistance.
  • Other yarns and filamentary materials may be used in the braided structure for known purposes such as the protection of the substrates from the damaging effects of high temperatures.
  • Thermally insulating yarns which may be treated with flame retardant or resistant coatings or filaments formed from plastics of the type known as aramids are conventionally employed for providing thermal protection.
  • a family of braided products of the type referred to is sold under the registered trademark EXPANDO by The Bentley-Harris Manufacturing Company.
  • Abrasion resistant braided sleeves of this type are disclosed in US Patent No 4,754,685.
  • This patent discloses a braided tubular sleeve comprising a resilient monofilament material and an abrasion resistant monofila ent material present in a ratio of from about one end of resilient material to two ends of abrasion resistant material up to about ten ends of resilient material to one end of abrasion resistant material.
  • the resilient material comprises a polymeric material of the type commonly referred to as an engineered plastics.
  • the resilient material has a tensile modulus of at least 100,000 psi and most preferably at least 1,000,000 psi and the abrasion resistant material comprises a polymeric material having a tensile modulus at least 50,000 psi less than the modulus of the resilient material.
  • Braided sleeving so formed is well suited for field installation over wire and cable bundles or harnesses, hoses and the like because the sleeving has an open weave construction which enables the braided tube to expand to several times its original diameter when the braided tube is axially compressed. When the axial compression is released, the braided structure is biased to return to its original smaller diameter due to the resilient nature of the engineered plastics material from which it is braided.
  • EXPANDO Other products sold by The Bentley-Harris Manufacturing Company under the registered trademark EXPANDO include material introduced into the braided structure which are heat resistant and flame retardant monofilament or multifilament materials. Relatively bulky yarns may be integrated into the braided structure for the purpose of adding further thermal protection or for damping vibration-produced noise. A sleeve having bulky yarns for damping of vibrations is shown in US Patent No 4,989,422. In certain applications, as for example, where the substrate itself is intended to have the capability of extended axial expansion, products of the type aforementioned do not have the capability of sufficient axial expansion to accommodate the need.
  • the present invention provides a braided sleeve comprised of a first material in monofilament form, the first material having a high modulus of elasticity.
  • the first material is provided either as individual monofilaments or groups of one to about five monofilaments.
  • the monofilaments are preferably formed of engineered plastics materials capable of taking a set, or may in certain instances be a resilient wire.
  • Interbraided with the first filamentary material is a second filamentary material chosen to impart a property to the sleeve which is dependent upon the type of protection that the sleeve is intended to afford.
  • the second material is formed optionally of monofilaments or of multifilaments or of combinations thereof, depending upon the desired properties of the sleeve.
  • Figure 1 shows a braided sleeve according to the present invention
  • Figure 2 shows a cross-sectional schematic view of the invention as it is utilised to protect an elongatable cable of the type utilised for connection of a telephone receiver to the base of the instrument;
  • Figure 3A-3D are schematic views illustrating the method of making sleeving formed according to the invention.
  • the braided sleeving of the invention comprises a sleeve 10 formed of a first filamentary material 11 made of a resilient material in monofilament form, which material is resiliently settable and is preferably a high modulus, engineered plastics material such as polyester, although resilient wire may be employed.
  • a second material 12 formed of a material having specific protective properties for a substrate such as flame resistance, thermal resistance or abrasion resistance. Suitable materials useful as the second material include nylon, metallic wire, aramid fibres, glass fibres and the like.
  • the second material may be provided in either monofilament or ultifilament form depending upon intended the end use c" the sleeve.
  • the second material may be e er a coated or uncoated bulky yarn as desired for the specific properties which are to be imparted to the product, as illustrated in Figure l.
  • the bulky yarn may have a denier of between about 100 and 7,000.
  • the sleeve is not braided so tightly so as to inhibit its ability to radially expand when axially compressed.
  • the braided sleeving of the kind provided in this invention is adapted to be formed on conventional circular braiders.
  • resilient monofilaments may be fed off one bobbin and monofilaments or yarns having a desired protective property fed off the next bobbin or if desired, both may be combined and fed off each bobbin.
  • the braided sleeve is provided with radially extending bellows or corrugations, 14.
  • the corrugations 14 may be provided in series of two or more, a series or group of four such corrugations being shown in Figure 2, eacir-series being separated by an uncorrugated portion. Alternatively, the entire length of sleeve may be formed with corrugations.
  • a sleeve formed in accordance with the invention is fitted over an elongated, helically coiled cable, generally indicated by 15.
  • suitable clamping means such as pressed metal clamps 16 secure each end of the sleeve to the cable 15.
  • an uncorrugated sleeve is mounted on a mandrel 17 and secured at one end thereto by a stop means, generally indicated by 18.
  • the sleeve material is then gripped by a clamping means 19 and pressed axially against the stop 18 to form a radially extending flange.
  • a second section of sleeve is gripped by the clamping means at a point displaced from the first flange and pressed towards the first flange.
  • a thermally resistant sleeve formed according to the invention was manufactured on a circular braider from 10 mil diameter polyester monofilament manufactured by Johnson Filament of Williston, Vermont as the resilient filamentary material and an aramid yarn of 400 denier sold under the trademark KEVLAR by E I DuPont as the secondary filamentary material.
  • the braider had 72 carriers, 50% of which were loaded with three ends of the monofilament polyester and the remaining carriers loaded with aramid yarn.
  • the monofilament polyester had a modulus of elasticity of 2 x 10 6 psi.
  • the resilient polyester monofilament had a softening point of about 400°F.
  • the sleeve off the braider had an inside diameter of l.o inches and was placed on a mandrel having an outer diameter approximately equal to the sleeve inside diameter with one end of the sleeve affixed thereto by a clamping ring.
  • Four accordion flanges or folds were formed sequentially by first gripping a section of the sleeve with a second ring at a location spaced approximately 1.0 inches from the first ring and pressing the sleeve material against the first ring. This process was repeated by sequentially holding the gathered material in position at a distance and pressing the next section against the first until four accordion folds were formed.
  • the sleeve produced in this Example has four corrugations in each of four groups with approximately 0.4 inches between each group.
  • the sleeve material prior to the formation of the corrugations had a length of 17 inches. After corrugation, the length was approximately 11 inches.
  • the sleeve was capable of extension to its original length and returned to the biased condition when its ends were released.
  • filamentary materials having resilient properties and those having properties which provide protection to the substrate can be determined after a few field trials.
  • filamentary materials providing substrate protection may be combinations of materials having different properties. For example, combinations of filaments of metal and strands or yarns of mineral materials such as glass or other combinations including natural and synthetically made filaments may be utilised.

Abstract

Gaine tressée (10) constituée d'une première matière qui se présente sous forme d'un monofilament (11) se caractérisant par le fait qu'il présente un module d'élasticité élevé et peut adopter une déformation rémanente élastique. La première matière est tressée avec une deuxième matière se présentant sous forme filiforme (12) qui est sélectionnée pour conférer une propriété à la gaine en fonction de son utlisation finale voulue. la gaine est ensuite traitée pour former une série de plis ou de soufflets (14) se projetant radialement, à déformation rémanente élastique, qui s'étendent linéairement sur la longueur du produit ou qui peuvent être groupés et séparés par des intervalles dans lesquels il n'existe pas de striures. Cette gaine peut subir une dilatation et une contraction radiales et peut donc épouser élastiquement la forme d'un substrat allongé dont la section transversale peut être irrégulière; par conséquent cette gaine peut donc s'allonger et se dilater axialement, d'une manière appréciable, pour protéger un substrat dont la propriété est de s'allonger et de se contracter axialement.
