Background Art Typical nets known to date include the so-called weaving knot net formed either by tightly loop winding method to provide a loop binding knot which is widely employed as a fishing net. The conventional knotting structure in the prior arts is generally related to the loop binding methods as shown on Fig. 7.

According to the prior art, the embodiments of knots have been improved in the pursuit of the tight binding of knots regardless of the usages. No composite function or special function related to the knot is expected for the application of knotting member except the secureness of net.

The tightened structure of knot may be disadvantageous in that the knotting member never detach by itself. Especially if the conventional fishing nets are disposed under the ocean or rivers, they become very harmful weapons to the fish or creatures in the ocean because the captured creatures therein shall be died, Furthermore the disposed nets occurs the contamination to the earth environment.

According to the prior art of the knot binding method for fabricating various net, the knot portion of net has no typical function except maintaining the opening of net.

Disclosure of the Invention This invention has been accomplished in view of the above-mentioned background and is intended to provide synthetic

resin knots for conforming the various purposes of net depending on the usages.

Accordingly, the present invention is to provided that new structure of knotting member which has diverse applications and manufacturing method for fabricating the knotting member embedded by the synthetic resin based on the three kinds of illustrations which are related to the formation of knotting member using the synthetic resin.

Best Mode for Carrying Out the Invention Hereinafter, the preferred embodiments of knotting member according to the present invention will be described in detail with the references of accompanying drawings.

Fig 1 is related to illustrate the structure and method for the

finished net under the present invention.

In contrast to the conventional knot mentioned on the Fig 7 of the prior art, the fabrication method and the structure under the present invention is totally different from the weaving knot net.

The manufacturing method under the first embodiment of present invention relates to the plastic molding processes which can effectively construct the plastic bonding material onto the intersection 3 resulting the knot embedded by the synthetic resin, and under the second embodiment of present invention relates to the joinable assemblies which can effectively construct the plastic joining material onto the intersection 3 resulting the knot embedded by the synthetic resin, finally under the third embodiment of present invention relates to the hot melt processes which can effectively construct the plastic boding material onto the intersection 3 resulting the knot embedded by the synthetic resin.

Hereinbelow, one should be noted that the vital embodiment of knotting member 4 under the present invention includes the technological application of plastic material made of synthetic resin.

Accordingly, the knotting member 4 under the present invention provides the valuable applications in the industries by means of the changes of shape, material, and color.

Under the application of present embodiment, the regular distribution of knotting member 4 denoted by its colors or shapes and the functional applications of material enhance the value of product and change the general concept of weaving net.

First illustration of the embodiment; The first illustration of the present invention is related to Fig 3 to Fig 4.

A flat mold 5 having vertical groove 6 and horizontal groove 7 is configured so as to set the warp 1 and weft 2. At the position of the intersections formed by the vertical groove 7 and the horizontal groove 6, the molding chamber 8 having the spherical shape are installed for the injection. Obviously, the appearance of molding chamber 8 can be freely configured such as elliptical figure or

rectangular form etc. depending on the purposes of the usages.

For the continuous fabrication process, plurality of roller 9 installed apart from the mold frame 5 supply continuously the wrap and weft though the vertical groove 6 and horizontal groove 7 along the specified direction.

As shown on Fig 4, the plurality of injection machine 11 are set to match the injection nozzles onto the molding chamber 8. The injections of synthetic resin occur simultaneously according to the up and down motion of injection machine 11.

As shown on Fig. 2a, the guide grooves 12a for the gates of the wrap and weft and the inner concaved groove having the preset shape corresponding to the appearance of knotting member 4 are configured.

Based on the above mentioned equipment, the multi head injection machine 11 injects continuously the synthetic resin onto the molding chamber 8.

By means of the point injection method, the net having the knotting member 4 embedded by synthetic resin is accomplished according to the embodiment of plastic injection.

In accordance with the demands or usages for the preferred net, the types of synthetic resin and choices of its colors can be selected with the wide applications. For the application to a fishing net, the present invention is especially useful in that the fishing net of knots having the decomposable synthetic material protects the environment of ocean. If there occurs disposal of fishing net made of the decomposable resin in the ocean, the reaction between the synthetic resin of knot and the salting property of ocean occurs during the period so that the binding of the junction knots are loosed resulting the decay of fishing net in the natural way for the creature in ocean.

For the case of the general industry, if the decomposable resin is used for making the knots of net according to the present invention, the buried net having the decomposable knots facilitates the decay of the net preventing the environment of earth.

As mentioned, the shapes and colors of knotting member freely

can be utilized for enhancing the decoration means or functional usages under the present embodiment. For example, utilizing the combination of color or shape of knotting member, one can use it for denoting any notice or sign thereon or also one can utilize for the advertising or distinguishing means in addition to the original function of net.

Of course, the opening of net can be configured in the special shape of diamond crossing type without difficulty rather than the rectangular shape of opening in the prior art. Furthermore according to the present invention, the shape of opening under present invention can be applied into a polygon shape with the appropriate setting of the roller in connection with the mold frame.

Second illustration of the embodiment ; Fig. 5 is related to the second embodiment of present invention.

This illustration is characterized in that the knotting member 4 relates to an assembly type which can be combined by means of a pair of joinable assemblies which are pre-fabricated by the separate process using the injected synthetic resin.

Accordingly, the pair of joinable assemblies 4a, 4b having the combining extrusion 4c and the combining intrusion 4d are set so as to match the intersection formed by the wrap 1 and weft 2. After the assembly combination, the joint portions of the knotting member 4 can be tightly secured by the process of high frequency heating or laser shot technique.

Although the embodiment of assembly member reveals the low productivity comparing with the other illustrations, the application under the second illustrated embodiment is suitable for manufacturing the functional net or special purposed net. For examples, the knotting member can be applied for utilizing the light emitting means, decoration means, perfuming means, advertising means, warning sign and any other means in addition to the original purpose.

Third illustration of the embodiment;

In connection with the third illustration, no drawing is illustrated but this application will be briefly described as followings, Third embodiment for bonding of the intersection 3 under the present invention can be completed using the thermally melted synthetic resin or the hot melt of synthetic resin induced by an ultrasonic heating or a thermal heating device onto the intersection 3.

In the case of ultrasonic heating device, the formation of knotting member 4 can be achieved selectively in accordance with the bonding onto the folded crossing intersection or the planar welding which is related to the bonding technique after cutting the folded crossing area.

Industrial Applicability According to the present invention, the applications to the industrial utilization is greatly enhanced because of the following reasons ; firstly when the invention is applied to a fishing net, the knotting member having decomposable synthetic material protects the ocean and the earth environment, secondly the functional net can be achieved depending on the size, shape, material and color of the knotting member for enhancing the demand or function of the net, thirdly the manufacturing methods of knotting member is widely selective as shown on the described illustrations, finally although the illustrated embodiments are related to the planar structure of net but it can be applied to a basketball net, for example, or any other three dimensional products.
