Through the first process, the nonslip member molding grooves 110 having a variety of patterns are formed in the mold 100. Here, each of the nonslip member molding grooves 110 having the variety of patterns may be formed in the mold 100. Also, the nonslip member molding grooves 110 of the mold 100 which have a variety of sizes with different thicknesses and areas are each formed so as to adequately adjust a thickness and a size of the nonslip member 20. That is, in the case of the nonslip members 20 attached to a front side, a rear side, an inner side, an outer side, and the like of a bottom of the sock 10, a thickness of the nonslip member molding groove 110 may be formed to be small. In the case of the nonslip members 20 attached to an arch part and the like of the sock 10, a thickness of the nonslip member molding groove 110 may be formed to be large.

(10) The present invention is provided to install the nonslip members 20 on the inner and outer sides of the sock 10. A molding position and a thickness of the nonslip member 20 depend on an event of sport and thus the nonslip member is manufactured at a place corresponding to a ground-contact position of a bottom of a foot. A method of molding the nonslip member 20 on the sock 10 is performed using the same method as described above.

(11) Although FIG. 1 illustrates a cross section of the nonslip member molding groove 110 of the mold according to one embodiment of the present invention, the nonslip member molding groove 110 of the mold 100 is not limited to that shown in FIG. 1. That is, a variety of such nonslip member molding grooves 110 of the mold 100 according to the present invention may be formed.

(12) According to the present invention, the nonslip member molding groove 110 of the mold 100 includes a plurality of air hole molding pins 120, as shown in FIG. 1, so that the nonslip member 20 includes a plurality of air holes 21 formed by the air hole molding pins 120 to be smoothly ventilated as shown in FIGS. 3A, 3B, and 3C. Here, the air hole molding pins 120 may be formed to have a variety of shapes.

(13) (Second Process)

(14) A second process is a process of inserting silicone which is a raw material of the nonslip member 20 into the nonslip member molding groove 110 of the mold 100 as shown in FIG. 2. Through the second process, the silicone which is a raw material of the nonslip member 20 is inserted into the nonslip member molding groove 110 of the mold 100.

(15) (Third Process)

(16) A third process is a process of inserting the mold 100 into the heating device and melting the silicone. Through the third process, the silicone inserted into the nonslip member molding groove 110 of the mold 100 is melted to be firmly attached to the inner side and the outer side of the sock 10. Here, when the silicone which is melted while being injected into the nonslip member molding groove 110 is solidified, the silicone is formed as the nonslip member 20.

(17) A support which supports a plurality of such molds 100 is installed in the heating device to be withdrawable like a drawer. A handle is provided on a front side of the support, a heating plate including a heater is installed above the support, and a control portion is installed below the heating device to control a temperature and the like of the heater.

(18) Accordingly, when the plurality of molds are placed on the support while the support is withdrawn outside the heating device and the support is pushed into the heating device, the silicone inserted into the nonslip member molding groove 110 of the mold is melted by the heating plate to be firmly attached to the inner side and outer side of the sock 10.

(19) (Fourth Process)

(20) A fourth process is a process of placing the mold 100 turned upside down on the sock 10 so as to come into contact with a nonslip member attachment portion of the sock 10 and inserting the same into the lower fixing plate of the press. Through the fourth process, the silicone melted by the heating device while in the nonslip member molding groove 110 of the mold 100 comes into contact with the nonslip member attachment portion of the sock 10. Here, a flat support plate is inserted into the sock 10 in advance so that the nonslip member attachment of the sock 10 is spread to be flat. Meanwhile, when the nonslip member 20 is attached to the inner side of the sock 10, the sock 10 is turned inside out and the support plate is inserted thereinto.

(21) Here, the nonslip member attachment portion indicates a part of the inner side and outer side of the sock 10 which needs the nonslip member 20. The nonslip member attachment portion may generally be the inner side or outer side of the bottom of the sock 10 or an arch part and the like of the sock 10. In addition, the part of the sock 10 which needs the nonslip member 20 may be the nonslip member attachment portion.

(22) Also, a thickness and a nonslip member pattern of the nonslip member attachment portion are applied depending on a position of being attached.

(23) (Fifth Process)

(24) A fifth process is a process of attaching the nonslip member 20 formed of silicone to the sock 10 by heat-pressing the mold 100 using an upper pressing plate of the press. Through the fifth process, the silicone melted by the heating device while being in the nonslip member molding groove 110 of the mold 100 is conjunctly pushed into a gap in a surface of the nonslip member attachment portion on the inner side or outer side of the sock 10 while simultaneously being conjunctly pressed against the surface by heat-pressing of the upper pressing plate to be firmly pressed thereagainst. Accordingly, the nonslip member 20 formed of silicone is firmly attached to the nonslip member attachment portion of the sock 10. Here, according to the present invention, since the upper pressing plate of the press heat-presses the mold 100 to attach the nonslip member formed of silicone to the sock 10, particularly, it is possible to also firmly attach the nonslip member 20 to the inner side of the sock 10 which is structurally fluffy.

(25) A heater is built in each of the lower fixing plate and the upper pressing plate of the press. A cylinder moving up the upper pressing plate is installed above the press. A control portion controlling an operation of the upper pressing plate, a heat-pressing time, a temperature of the heater, and the like is installed below the press.

(26) Accordingly, when the sock 10 on which the mold 100 is mounted is placed on the lower fixing plate while the upper pressing plate has been moved up and then the upper pressing plate is moved downward, since the upper pressing plate heat-presses the mold 100 to the sock 10 for 10 to 30 seconds while moving downward, the nonslip member 20 formed of silicone may be firmly and simply attached to the inner side or outer side of the sock. Here, since the upper pressing plate is automatically moved upward after the nonslip member 20 is completely attached, a subsequent attachment operation may be performed after the sock 10, to which the nonslip member 20 is attached, is extracted. While the sock 10, to which the nonslip member 20 is attached, has been extracted as described, when the nonslip member 20 is solidified and the mold 100 is extracted from the nonslip member 20, the operation is completed.

(27) According to the present invention, as shown in FIGS. 3A, 3B, and 3C, the nonslip member 20 may be attached to any one of the inner side and outer side of the sock 10 or may be attached to each of the inner side and outer side. That is, the nonslip member 20 may be attached to only the outer side of the sock 10 as shown in FIG. 3A. Also, the nonslip member 20 may be attached to only the inner side of the sock 10 as shown in FIG. 3B. In addition, the nonslip member 20 may be attached to each of the outer side and inner side of the sock 10 as shown in FIG. 3C. Here, according to the present invention, a process of attaching the nonslip member 20 to the inner side of the sock 10 and a process of attaching the nonslip member 20 to the outer side of the sock 10 are formed as separate processes.

(28) Although FIGS. 3A, 3B, and 3C illustrate states in which the nonslip member 20 is attached to a front of the bottom of the sock 10 as examples of the present invention, according to the present invention, the nonslip member 20 may be attached to each of parts which need the nonslip member 20 such as a rear of the bottom of the sock 10, an arch part of the sock 10, and the like.

(29) Meanwhile, FIGS. 4A to 4M illustrate a variety of examples of the nonslip member 20 according to the present invention. According to the present invention, as shown in FIGS. 4A to 4M, the nonslip member 20 attached to the sock 10 may be formed to have a variety of shapes and patterns.

(30) In a structure for attaching a nonslip member to each of both sides of a sock according to the present invention, as shown in FIGS. 1 to 4M as basic features of the technical components thereof, a nonslip member molding groove 110 is formed in a mold 100 configured to attach a desired-patterned nonslip member 20 to a part of a sock 10 which needs nonslip member, silicone which is a raw material of the nonslip member 20 is inserted into the nonslip member molding groove 110 of the mold, melting the silicone by inserting the mold 100 into a heating device, the mold 100 turned upside down is placed on the sock 10 to allow the silicone melted in the heating device to come into contact with a nonslip member attachment part of the sock 10 and is inserted into a lower fixing plate of a press (not shown), and the nonslip member 20 formed of silicone is attached to the sock 10 by heat-pressing the mold 100 using an upper pressing plate of the press.

(31) Here, the sock 10 according to the present invention is applied to a general sock, a variety of sport socks, socks for fashion and climbing, and the like. The nonslip member 20 having a variety of patterns is firmly attached to a part of the inner side or outer side of the sock 10 which needs a nonslip member through the mold 100.

(32) The nonslip member 20 is firmly attached to each of the inner side and outer side of the sock 10 through the mold 100, and the nonslip member 20 is formed of silicone. Here, the nonslip member 20 may be attached to each of the both sides of the sock 10 with a variety of shapes as shown in FIGS. 4A to 4M.

(33) Also, in the present invention, even when a thread of the sock 10 is thick or fluffed or a thread weaving the sock 10 protrudes lengthwise therefrom, the nonslip member 20 is pressed against and melted to the sock 10 to be firmly attached thereto using the mold 100 instead of an existing sticker (decal) type or silk printing method.

(34) According to the present invention, the nonslip member 20 includes the plurality of air holes 21. Here, since the nonslip member 20 includes the plurality of air holes 21 formed to be smoothly ventilated, the nonslip member 20 may be prevented from becoming wet during exercise such that it is possible to prevent a water membrane from being formed on the nonslip member 20 which destroys or degrades the nonslip member function.

(35) According to the present invention, the nonslip member 20 may be attached to any one of the inner side and outer side of the sock 10 or may be attached to each of the inner side and outer side. Here, since the nonslip member 20 is attached to each of the inner side and outer side of the sock 10, it is possible to effectively prevent slipping between a foot and a sock and the sock and a shoe.

(36) In the present invention configured as described above, when the nonslip member 20 is formed on the sock 10, silicone is inserted into the mold 100 and then heated and the mold 100 is placed on the sock 10 and pressed by the press so as to attach the nonslip member 20 to each of both sides using a molding method. Here, a thickness of the nonslip member 20 may be freely selected and attached to a rubbed part of a bottom of a foot according to an exercise event. Also, the present invention is applied to the sport sock 10, and there are effects of preventing a foot from slipping and being contorted during exercise and of minimizing a feeling of fatigue by absorbing a shock transferred to the foot.

(37) Accordingly, in the present invention, since the nonslip member 20 formed of silicone is attached by heat-pressing the mold 100, in which silicone is inserted, against the sock 10, the nonslip member 20 having a variety of patterns may be firmly attached to a part of the inner side and outer side of the sock 10, which needs a nonslip member, by structurally using the mold 100. Particularly, since melted silicone is heat-pressed against the sock, an advantage of firmly attaching the nonslip member 20 even to the inner side of the sock 10 which is fluffy and an effect in which the nonslip member 20 is not separated from the sock while being washed is present.

(38) Also, in the present invention, since the nonslip member 20 attached to the sock 10 includes the plurality of air holes 21 formed to be smoothly ventilated, it is possible to prevent the nonslip member 20 from becoming wet during exercise so as to provide an advantage of preventing a water membrane from being formed on the nonslip member 20 which destroys or degrades the nonslip member function.

(39) Also, since the nonslip member 20 is formed by attaching the silicone inserted into the nonslip member molding groove 110 of the mold 100 to the sock 10 in the present invention, there is a structural advantage of adequately adjusting a thickness and a size of the nonslip member 20 according to a thickness and an area of the nonslip member molding groove 110 formed in the mold 100.

(40) Also, since it is possible to attach the nonslip member 20 to a rubbed part of a bottom of a foot according to an exercise event, there are advantages of preventing blisters by decreasing a frictional coefficient generated for each of a variety of exercise events during exercise, preventing distortions of the foot and the sock 10 by applying the nonslip member to a sport sock during exercise, and providing improved workability and high quality at a competitive cost to consumers.

(41) In addition, according to the present invention, there are advantages of completely remedying conventional problems including not only grip between the sock 10 and the floor but also a slipping phenomenon between a foot and the sock 10, providing a great effect in strengthening performance by increasing a sense of contact with a shoe during sport activities, reducing manufacturing costs so as to achieve excellent price competitiveness and durability, and being modifiable into a variety of designs.

(42) Comparison among the both-sided nonslip member sock of the present invention configured as described above, an existing nonslip member sock of company W, and a general nonslip member sock is shown in Table 1 below.
