DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following detailed description of the operation principle of the preferred embodiment of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the gist of the present invention unnecessarily obscure.

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 5 attached hereto. It is to be understood that the drawings shown in the accompanying drawings are only exemplary and are not intended to limit the present invention.

1, the present invention includes a knitting apparatus 2 for forming a fabric or a loop of a fabric such as a woven fabric or a knitted fabric, a yarn feeding device (not shown) for supplying yarn to the needle 200 or hook of the knitting apparatus 2 1 and a winding device 3 capable of taking out the fabric made from the knitting device 2 from the knitting device 2 and putting it in a box.

In particular, the knitting machine 2 includes a plurality of needles 200 which are circularly shaped and are rotatable in the shape of a central axis of a horizontal plane, and a cylinder 300 which provides a moving passage for the needle 200 to move up and down. And a sinker (100) provided at an upper end of a dial (500) provided at an upper end of the cylinder and rotating together with the cylinder (300). As the yarn is supplied from the yarn feeding device (1) And the forward and backward movement of the sinker 100 and the forward and backward movement of the sinker 100 form a loop, and the formed loop is pushed by the sinker 100 as a central axis of rotational movement, It is possible to fabricate the fabric by repeatedly forming the needles such that the loops are formed in the loops made earlier.

Referring to FIGS. 2 and 3, the sinker 100 is formed into a plate having a predetermined width. When the needle 200 rises as the needle 200 moves forward and backward, the sinker 100 closely contacts the needle 200 It will be able to pass.

The sinker 100 includes a sinker head 140 through which the loop formed between the needles 200 and connected to the upper end can be positioned, and a loop that contacts the loop so that the loop can be pushed toward the center of rotation A sinker groove 122 formed at an upper end of the sinker head 140 and a nose 124 surrounding the sinker groove 122 and protruding in a direction to push the loop away from the sinker head 140 .

In addition, the sinker 100 is formed with an underbar 120 protruding from a lower end of the sinker head 140 so as to be spaced apart from the sinker head 140.

The under bars 120 may be formed in one or a plurality of the through holes so that the under bars 120 can pass through the cylinder 300 separately from the sinker heads 140 which can be positioned above the cylinders 300.

Here, the cylinder 300 may be formed with a through hole 320 penetrating to correspond to the position of the underbar 120, and may be formed with a hole having a predetermined depth without being penetrated, 300 may be provided at the upper end of the cylinder 300 so as to allow the underbar 120 to pass therethrough.

The under bars 120 may be formed to have different lengths so that the cylinder 300 may be formed without penetrating the under bars 120 passing through the cylinders 300 according to the degree of movement of the sinkers 100. [ The under bars 120 may be formed on the outer circumferential side of the under bars 120.

Accordingly, the degree of friction of the underbar 120 with the cylinder 300 can be appropriately adjusted according to the intensity of the vibration that can be increased according to the degree that the sinker 100 moves away from the dial 500, It is possible to control the vibration of the sinker 100 which performs repetitive motion.

In addition, the under bars 120 may be formed to be spaced apart from each other, and the degree of the spacing may be different from each other. For example, the underbar 120 may be formed to have a gradually narrower or wider gap in the upward or downward direction.

Further, the under bars 120 may be formed to have different widths, and the under bars 120 may be formed to be narrower or wider as they are directed upward or downward.

In one embodiment, the sinker 100 is advanced from the dial 500 and relatively longer than the tether bar 120, so that the underbar 120, which is first contactable with the cylinder 300, moves back and forth So that the distance between the sinker head 140 and the sinker head 140 can be increased and the width of the sinker head 140 can be reduced to reduce friction.

In addition, the width of the sinker head is relatively larger than that of the underder bar 120 so that the sinker 100 can be smoothly prevented from moving upwardly when the sinker 100 is maximally moved forward and backward, 140 or the underder bar 120 is small, so that the sinker 100 can be prevented from being bent.

In addition, the underbar 120 is formed such that the tip thereof toward the cylinder 300 is inclined downward.

The underbar 120 can be formed to have a wider opening at a space apart from the inclined tip so that the sinker 100 is moved forward by the vibration generated when advancing toward the cylinder 300 It is possible to prevent the underbar 120 from being inserted into the through hole 320 of the cylinder 300 properly.

Also, when foreign matter accumulating in the through hole 320 of the cylinder 300 is entangled and accumulated in the underbar 120, the foreign matter may be accumulated in the through hole 320 of the cylinder 300 by the inclined tip of the underbar 120, So that it can be smoothly flowed along the inclined surface to be removed.

In addition, the underbar 120 has a plurality of dust-preventing grooves 126 formed on both sides of the cylinder 300 through which the cylinder 300 can contact.

The dust-preventing groove 126 is formed through a side surface of the underbar 120 to form a hole or a groove having a predetermined depth, so that the sinker 100 moves forward and backward, It is possible to prevent accumulation of foreign matter in the through hole 320 through which the sinker 100 passes, and to prevent accumulation of foreign matter.

Referring to FIG. 4, the underbar 120 may be formed to be inclined toward the side. That is, the under bars 120 can be formed so as to be inclined downward toward one side or both sides so as to minimize the area of the upper side or the lower side of the under bars 120 that can contact the cylinder.

Therefore, the degree of friction between the surface of the underbar 120 and the surface of the cylinder can be minimized by the underbar 120 inclined toward the side surface, and foreign matter is trapped between the respective surfaces .

1 and 4, the needle 200 and the sinker 100 of the present invention are moved up and down and forward and backward in a state where at least one needle butt 220 is formed on one side of the needle 200 So that the butt is directed to the outer circumferential side in a cylindrical cylinder having a moving passage formed at a predetermined height from the horizontal plane. As the cylinder 300 rotates, a knitting cam box (not shown) having a plurality of cams on the cylinder 300 side so that a needle butt 220 of the needle 200 vertically moves in one direction 400, and the needle burt 220 moves along the passage according to the shape of the passage, so that the needle 200 can move up and down.

The sinker 100 has a plurality of dial grooves 520 rotatable together with the cylinder 300 on the uppermost circumference side of the cylinder 300 with at least one sinker butt 180 formed on one side thereof And is provided at the upper end of the formed dial 500 so that the sinker butt 180 faces upward. As the dial 500 rotates, the sinker button 180 of the sinker 100 advances and retreats between the rotation center axis and the cylinder 300, and the dial 500 The sinker butt 180 moves along the cam shape according to the shape of the cam of the sinker ring 600 and the sinker 100 is moved forward and backward according to the shape of the cam of the sinker ring 600. [ You will be able to exercise.

5, the through hole 320 of the cylinder 300 is formed at a position corresponding to the plurality of sinkers 100, and the underbar 120 of the sinker 100 is inserted or inserted .

Further, the lower portion of the through-hole 320 may be inclined downward or inclined downward in a direction in which the sinker 100 is inserted or in a direction in which the sinker 100 is inserted, so that the foreign matter inserted by the underbar 120 drops downward So that it is possible to prevent foreign matter from accumulating in the through hole 120.

When the lower portion of the through-hole 320 is formed to be wider than the width of the under-bar 120, the two under bars 320 may be vertically spaced apart from each other. 120 may be inserted.

That is, the two under bars 120 are inserted into contact with the upper side and the lower side of the through holes 320, and the under bars 120 located at the lower side are connected to the lower side of the through holes 320 So that the sinker 100 can be prevented from being raised by the upper under bar 120. The under bar 120 is moved back and forth to the sinker head 140 by the lower under bar 120, So that it is possible to form the loop at an accurate position without slackening.
