Definitions

  • the present invention relates to a method for joining together two or more articles using a flexible cord which is wound at least twice around at least a part of said articles to form a knot.
  • the invention further relates to a device which is suitable for carrying out the method.
  • the method is particularly intended for use in the fishing industry for binding nets to support lines and chains.
  • Fishing nets used in trawling are made up of several net sections which are joined to each other via a ripline.
  • the ripline normally has a diameter of between 10 mm and 35 mm, though is typically around 28 mm. Edge regions of the net sections are gathered to form selvedges which are then bound to the ripline using a woven cord of around 4 mm diameter.
  • the binding operation is performed manually at distinct locations along the ripline. The operation consists of threading the cord on a dolly and passing the dolly through a mesh in the net adjacent the selvedge and around the rope several dozen times at each location. After each winding, the cord must be pulled tight.
  • the operation is completed by passing the dolly under one or more windings to secure the bind.
  • the net also comprises a so-called bolseline bound in the manner described above to the lower leading edge of the net. To this bolseline is further bound a steel chain, typically of HLC 13-8 dimensions, which is attached to the hauling gear of the trawler.
  • the net may also be provided with a footrope to which gear such as rockhopper gear can be shackled.
  • the bindings In order to be able to exchange sections of netting or to replace gear, the bindings must be quickly releasable. This implies that the cord used for the bindings must be cuttable with a bladed instrument, thereby ruling out the possibility of using a wire-wound binding or similar.
  • the method according to the present invention makes use of a flexible cord which is wound at least twice around at least a part of the articles to form a knot.
  • the method is characterized in that the articles are components of trawler fishing equipment, and in that the knot is influenced by mechanical means to create a tension in the knot of the order of at least several hundred Newtons.
  • a mechanical device can be quickly connected to one end of the cord to pull the cord tight to a predetermined tension.
  • the device comprises a stationary member which during use is stationary with respect to the articles around which the cord is wound, the stationary member being provided with an abutment member for abutment against at least one of the articles which are to be joined, the abutment member presenting two spaced-apart adjacent jaw members, each jaw member being provided with a substantially U-shaped opening for accommodating at least a portion of at least one of said articles which are to be joined; and means associated with the stationary member for holding the cord and displacing it with respect to the stationary member.
  • the partial net shown in Fig. 1 is of the Whitefishtrawl model "Bering Sea” type made from braided polyethylene netting. It is to be noted that only the front region of the net is shown in Fig. 1.
  • the partial net comprises two main sections, i.e a lower section 1 and an upper section 2. The sections are joined to each other along their adjacent edges via riplines 3 (two shown in the drawing) of around 28 mm karat rope.
  • the lower net section 1 is further provided with a bolseline 4 at its leading edge 5. This line 4 may similarly be 28 mm karat rope.
  • a chain 6 is affixed to the bolseline 4.
  • the chain 6 also serves as an attachment for rockhopper gear (not shown).
  • the leading edge of the upper net section 2 is provided with a combination rope of around 24 mm diameter.
  • Fig. 2 shows a part of the lower section 1 of netting to the leading edge 5 of which a bolseline 4 and a chain 6 are attached.
  • the leading edge 5 is formed by gathering up a length of netting to form a selvedge and then securing it to the bolseline 4 at intervals along the line by means of wound bindings 7.
  • the chain 6 is attached to the bolseline 4 at intervals therealong by means of wound bindings 8.
  • the wound bindings 7 and 8 are achieved by threading a woven cord of around 4 mm diameter on a dolly and then passing the dolly through a mesh in the net and around the bolseline several dozen times at each location. After each winding, the cord must be pulled tight to maintain the required tension in the binding. The operation is completed by passing the dolly under one or more windings to secure the binding.
  • Fig. 3 illustrates a section of netting corresponding to that shown in Fig. 2, though in which the bindings between the net 1, bolseline 4 and chain 6 are achieved in accordance with the present invention.
  • the bindings 9 are achieved by winding a length of cord 10 (see Fig. 4) at least twice around at least parts of the articles to be joined to form a knot.
  • the knot shown in the drawings and most clearly illustrated in Fig. 4 is a so-called clove hitch, though it will be apparent that many other types of knot may also be suitable.
  • the cord used to form the knot in the method according to the present invention may be somewhat thicker, for example 14 mm.
  • the cord is wound to form a knot and is then influenced by mechanical means to create a tension in the knot of the order of at least several hundred Newtons, preferably between 1.000N and 50.000N, though normally between 1.500 and 5.000N.
  • mechanical means for producing the desired tension in the knot is portable and hand-held.
  • Devices suitable for performing the method according to the present invention are shown in Figs. 5, 6 and 7.
  • the device illustrated in Figs. 5 and 6 is generally denoted by reference numeral 11 and comprises a generally cylindrical, hand-held housing 12 within one end of which a motor 13 is accommodated.
  • the motor 13 may be driven electrically, hydraulically or pneumatically.
  • the motor 13 drives a worm gear arrangement 14 or similar within the housing 12.
  • the worm gear arrangement converts the rotational motion of the motor into translational displacement of an elongated rod 15.
  • the device is so constructed that, in an initial position, the elongated rod 15 is substantially entirely accommodated within the housing 12.
  • the motor 13 is activated to operate in a first direction, the rod 15 is caused to extend from the housing 12 in a direction away from the motor 13, as shown in Fig. 6.
  • the direction of rotation of the motor 13 is reversed, the rod 15 is caused to be retracted towards its initial position.
  • the amount which the rod 15 is caused to extend from the housing 12, i.e. the stroke of the device is selected depending on its intended use, though preferably lies between 100 and 300 mm.
  • an abutment member generally denoted by reference number 16.
  • the abutment member 16 may be secured to the rod 15 by any suitable means, such as by welding or by means of a bolt passing through the abutment member and engaging with internal threads in a bore in the end of the rod 15.
  • the abutment member is releasable to facilitate exchange thereof.
  • the abutment member 16 comprises two adjacent jaw members 17, separated by a distance d. Each jaw member 17 is provided with a substantially U-shaped opening 18 of a certain width w and depth 1. The values of the distance d, the width w and the depth 1 are selected depending on the intended field of application of the device.
  • the distance d can suitably vary between 30 and 60 mm, the width w between 35 and 65 mm, and the depth 1 between 45 and 75 mm.
  • the distance d is greater between the jaws 17 at the upper region of the abutment member than at the lower region.
  • the device 11 be provided with a selection of abutment members 16 of differing sizes.
  • gripping means 20 On the housing 12 in the vicinity of the end from which the rod 15 extends, there is provided gripping means 20, for example in the form of two opposed gripping members 21 resiliently biased towards each other.
  • the gripping means 20 is intended to grip at least one end of the cord 10 which for example forms the knot illustrated in Fig. 4.
  • the gripping means 20 may instead be in the form of a forwardly inclined capped peg around which the ends of the cord 10 can be wrapped.
  • the cord 10 is wrapped at least twice around the articles to be joined to form a knot. Thereafter, the abutment member 16 on the rod 15 is placed against one or more of the articles to be joined so that at least a portion of at least one of the articles is accommodated within the openings 18 of the jaw members 17. One, though preferably both, end of the cord 10 is then inserted in the gripping means 20. Upon actuation of the motor 13, the housing 12 and thereby the gripping means 20 are displaced away from the knot, as shown in Fig. 6, to impart a tension in the cord 10. When the knot is suitably taut, the cord 10 can be severed along its length between the knot and the gripping means 20.
  • the device illustrated in Fig. 7 is generally denoted by reference numeral 30 and comprises a substantially Y-shaped housing 31.
  • an abutment member 16 of the type described with relation to the embodiment shown in Figs. 5 and 6.
  • a handle 32 is provided on the other branch of the housing 31 opposite the abutment member 16.
  • a motor 13 having a spindle 33 is arranged within the housing 31 in such a manner that the spindle 33 of the motor projects from the housing and extends transversely to an imaginary line joining the abutment member 16 with the handle 32.
  • Gripping means 20 is provided on the spindle 33 and is arranged for rotation therewith.
  • the gripping means 20 is suitably in the form of a split pulley 34, the two halves of which can be brought together to thereby clamp an item placed therebetween. In the present case, such an item would be the ends of the cord 10.
  • the cord 10 When operating the device according to Fig. 7, the cord 10 is wrapped at least twice around the articles to be joined to form a knot. Thereafter, the abutment member 16 on the housing 31 is placed against one or more of the articles to be joined so that at least a portion of at least one of the articles is accommodated within the openings 18 of the jaw members 17. One or both ends of the cord 10 are then inserted in the gripping means 20. Upon actuation of the motor 13, the gripping means 20 is caused to rotate to impart a tension in the cord 10. When the knot is suitably taut, the cord 10 can be severed along its length between the knot and the gripping means 20.
