Description

PROCESS AND ROPE WITH OPTIMIZED PLASTIC DEFORMATION

Field of Application [001] The object of the present invention relates to the improvement of a multifilament or plastic monofilament rope used in various professional and leisure activities, and is especially useful for remotely looping animals, fishing with tar and similar. , whose constructiveness employs a process of heat treatment at high temperatures after its making, twisted, braided or crossed, of its filaments that gives it better performance and optimization regarding the plastic physical memory, that is, property by which polymers tend to return to the initial position after induced flexion.

Thus, in the patent application there is a multifilament or plastic monofilament cord which belongs to the field of safety products and sporting activities which confers differentiated plastic properties compared to traditional monofilament or multifilament cords when it suffers a heat treatment after its shape.

It is also, within the scope of the present application, to present the improvement of a multifilament or monofilament rope, with low costs for its industrial feasibility, adding requirements of robustness, safety and reliability, reaffirming its utilitarian concept, giving the user freedom. additional choice and choice in the similar market, offering numerous possibilities and benefits, becoming a product with great acceptance and expectation for the reference market.

Arrangement History [004] Multi-stranded or single-stranded ropes are constructed of several strands which are braided into distinct groups, and this weft technique gives them high breaking strength and relative flexibility in handling.

[005] The ropes thus produced are used for remotely looping animals, composing linear fishing nets and netting, or to support general sporting activities.

Deficient points of the state of the art [006] Currently, multifilament strings or plastic monofilaments have very low physical memory, that is, defined by plastic regeneration in returning to the initial state when they are driven to deviate from their rectilinear form and tend to remain in the imposed position, no longer returning to the starting position by themselves.

When a circle with the low memory rope is formed from a rectilinear segment, it is observed that it does not return to the shape of a semi-straight line and the softer they can be wrapped more easily.

On the other hand, the stiffer it is, the harder it is to be handled as to the shape one wishes for not returning to the rectilinear position by itself after applying the force that shaped it, thus requiring the commitment of new force with the same. counter-intensity to return to the original position.

[009] For example, a rigid rope used in fishing that needs to keep a net stretched: when receiving external forces that pull it out of this position, it will need an equivalent force, in the opposite direction that modified its disposition, to return it. to the starting position, which requires extra effort from the fisherman. Another example: A fisherman needs to apply great force to throw a net. Much of the force exerted in this pitch is destined to the opening of the net, that is, the objective is to make the entire periphery as far as possible from its center, forming a perfect circle. Therefore, part of the force applied to the pitch is intended to make the lead-guiding rope located at the edges of the net form a circle as much as possible. Since today's strings need external forces to maintain their straight direction, this feature often prevents the opening of the net from forming a perfect circle, resulting in uneven formation.

[010] Similarly in the livestock sector, animal loops face the same difficulties in throwing multifilament ropes or plastic monofilaments, as these ropes form irregular circles when retracted after their throwing against animals, and these irregularities arise because the rope It receives the same action as handling forces that modify the originally circular shape. These strings also do not return to their original circular formation.

[011] The above cited changes, in perfect circle shape of the original loop, make it difficult to throw the rope, since it requires the need for great effort by the looper at the time of casting, aiming to correct the irregular circular position of the rope, for the stretched position, situation that the loop encounters when it is thrown at the target animal.

GB1290900 describes a string with metallic filaments surrounding non-metallic threads made of synthetic thermoplastic material which is heated to its softening point, whereby the fiber shrinkage or shrinkage does not occur at this glass transition. It is despicable. The plastics material is made more specifically of polyethylene, polypropylene or polyamide. In this document the twisted metal filaments of the rope are filled by the softened polymer in its interstices. However, the invention taught here seeks the maximum shrinkage of the fibers through high temperatures to the limit of fiber degradation, which causes the fibers to shrink over each other, creating a "permanent stress field" throughout the section. of the rope. This shrinkage provides the advantageous effect of rope memory gain. In addition, the heat treatment in the present invention is applied to the already woven rope, which provides the advantageous technical effect of increasing its elasticity, as it leaves the fibers retracted and tensioned, thereby increasing the angle of the yarn assemblies that compose it. wake up.

[013] Document CN1064906 deals with a soft cable used in the automotive industry which teaches a method of plasticizing said cable where the plastic raw materials are mixed and heated near melt state to coat the rope surface evenly. The thickness of the coating is 0.2 to 0.6 mm. This invention aims to provide more safety to vehicles, the process of obtaining the cable being distinct from the present invention, since it only aims at covering said cable with heated plastic material in order to improve its transmission efficiency, reducing its deformation. In the present invention the maximum shrinkage of the plastic filaments is sought at the limit of degradation in order to promote the gradual shrinkage of the fibers, becoming more uniformly aligned. This shrinkage provides the advantageous effect of rope memory gain.

Layout Summary [014] Thinking of the technical aspects of how to improve and optimize the conditions of use for conformation of strands with multifilaments or monofilaments, aiming to improve their performance by reducing physical effort in their handling, improving the elasticity attributes for manipulation of folds and loops with minimal effort by the user under any conditions, led the inventor, a person in the field, to design and develop the object of the present patent, "OPTIMIZED PLASTIC DEFORMATION PROCESS AND ROPE", which idealizes a process of industrialization unpublished rope, as well as the rope resulting from this process, with characteristics that exceed the qualities of conventional multifilament or plastic monofilament strings.

[015] Thus, the present patent of "OPTIMIZED PLASTIC DEFORMING PROCESS AND ROPE" has been foreseen for the purpose of improving the simplest possible multifilament or monofilament rope, conveniently designed and engineered to allow safe use. Reliable, high performance, performing its functions with efficiency and quality, demonstrating unmatched practicality and versatility, incorporating unique features.

Detailed description of the embodiments [025] According to what the above related illustrations illustrate, "OPTIMIZED PLASTIC DEFORMING PROCESS AND ROPE" devises an unprecedented process for rope industrialization, as well as the rope resulting from this process, whose characteristics exceed the qualities conventional strands (1) of multifilament or plastic monofilament (2).

[026] The process consists of applying a controlled temperature directly to the already woven rope (3) over a given period of time sufficient to effect the maximum shrinkage of the plastic filaments (2) to the limit of their degradation temperature. , which is higher than the glass transition temperature.

[027] Through the maximum shrinkage of the plastic filaments (2), achieved through the thermal process, which occurs up to the polymer degradation limit temperature, a rope (3) is obtained with differentiations and advantages over the strings. conventional multifilament or plastic monofilament (2). Thus, the rope (3) comprises an increase in elasticity, since the retracted and tensioned fibers have an increase in the angle of the filaments that make up the rope.

[028] The string (3) is ultra-compact due to the better accommodation of the multifilament or plastic monofilament (2) so that this compaction produces a string (3) of relative weight (weight x section) greater than the multifilament or plastic monofilament strings. (2) present, which is a great advantage for rope applications that require low air resistance, given, for example, in an animal-throwing pitch, when the rope will require less effort by the loop as it will overcome air friction more effectively.

[029] Another advantage of compaction in the invention of the rope forming process is its firm presentation, that is, it does not give in to the manual pressure exerted by the user. This feature allows for greater firmness in the grip of the rope, helping to avoid slipping of the hands during handling.

[030] The rope of the present invention has high physical memory, far superior to conventional plastic multifilament ropes, with maximum retraction, which results in better filament alignment, and consequently high physical rope memory (3).

[031] Beginning the process of gradually shrinking the fibers, they are tensioned with more uniform alignment, seeking to accommodate each other in the structure of the rope. This accommodation allows the reduction of friction between these fibers, since if previously misaligned, correct this disharmony, resulting in an optimized parallel arrangement, which allows them to work together, providing greater lightness and free of much of the friction occurring in the strings. conventional (without heat treatment).

[032] The retraction characteristic of multifilaments or monofilaments allows all filaments to be permanently tensioned (stretched) in the structure, exerting continuous force in order to maintain the linearity of the rope, and this generated tension is responsible for the strong physical memory. presented by the innovative rope.

[033] Advantages of the new rope over the strong physical memory achieved. Maintenance of regularity: The permanent internal stresses of the new rope also preserve the regularity of the bends in the rope after its use, avoiding definitive distortions and deformations.

[034] Return of the rope by itself to the starting position, even after several flexions, where a loop returns to the original position after flexion interruption.

Advantageous differentiation of the new rope is also reflected in the reduced effort exerted by the looper when throwing the rope, as there is no need to correct rope irregularities, as with conventional ropes, where this action is facilitated by the tendency of linearity that strong physical memory imposes.

Even when soft, the plastic ropes produced with the process of the invention acquire tensions in their filaments, making it difficult to curl themselves, which has great benefit to the manipulator, who gains agility in unwinding and storing the rope.

[037] A rigid rope also has advantages over conventional rope because its handling is easier and requires less effort in many jobs. By exerting back force on its own in the linear disposition, as previously shown in the feature of filament retraction, it considerably reduces the need for external force to return to this disposition even after voluntary or involuntary flexions of the manipulator, given as an example, a rigid rope used in fishing, when a net is required to be stretched, has to receive external forces to pull it out of this position, which will require less force to return to the starting position, for the rope itself will tend to return to the initial linear position, reducing the effort of the fisherman.

[038] It is found that tuners (4) using the rope of the present invention as a lead guide are easier to throw open with less effort, as the rope located at the edge of the net will help (with his physical memory) to form a more open and perfect circle, the fisherman's goal.

[039] The rope, once treated with the process of the present invention, presents an increase of elasticity, in function to present its retracted and tensioned fibers, with increasing of the angle of the sets of wires that compose the rope.

[040] The above statement is true, as can be seen from the illustrations in Figures 7 and 8, when in Figure 7 you have a view of a conventional rope (1), which has not been subjected to a process of heat treatment and therefore has its plastic multifilaments (2) arranged at a closer angle (a).

Figure 8 illustrates a view of a rope (3) of the present invention, which has been subjected to a heat treatment process, and therefore has its plastic multifilaments (2) arranged at an angle (a) further open, which gives the rope (3) a high physical memory but at the same time good rope flexibility (3).

Thus it can be seen from the above that "PROCESS AND ROPE WITH OPTIMIZED PLASTIC DEFORMATION" is characterized as an improvement of a multifunctional rope that presents all the different practical and performance qualities, when compared to the existing conventional models. in the sectorial market.

[043] For the advantages it offers and for being truly inventive features that meet all the originality requirements in the genre, attest that the present, "PROCESS AND ROPE WITH OPTIMIZED PLASTIC DEFORMATION", meets the necessary and sufficient conditions for merit the Patent Privilege of Invention.
