Description

[0001] The present invention relates to a knitted goods having a hollow formed by a continuous process,

The present invention relates to knitted fabrics such as stockings, socks and the like, and more particularly to knitted fabrics in which holes and a closed structure are formed at desired positions during the knitting process.

Generally, knitted fabrics are manufactured in such a way that the loops are continuously connected through the reciprocating movements of the needles. Such knitted fabrics include stockings, socks, sweaters, vests, and shawls.

The knitting machine for producing a knitted fabric can be largely divided into a circular knitting machine and a horizontal knitting machine. Of these knitting machines, a circular knitting machine is widely used for the production of stockings, socks and the like. As shown in FIG. 1, A plurality of needles 30 inserted into the plurality of insertion grooves 11 and a plurality of needles 30 inserted in the insertion grooves 11 at the bottom of the needles 30 40).

Although not shown in the drawing, a feeder for feeding yarn to the needle 30 is provided at an upper portion of the cylinder 10, and generally four feeders are disposed at intervals of about 90 degrees.

Each needle 30 includes a hook 32 formed at the upper end thereof for hanging a thread supplied from the feeder, a latch (33 in Fig. 2) rotatably coupled to the lower portion of the hook 32, And a butt 34 protruding outward of the knee joint 40. In general, about 400 needles 30 are used in the knitting machine for stocking.

A cam block (not shown in the figure) is provided on the outer side of the cylinder 10 so as to be capable of moving forward and backward. The cam block is provided with a needle cam And a stitch cam that provides a descending path.

Accordingly, when the cylinder 10 is rotated, a plurality of needles 30 mounted on the cylinder 10 sequentially move up and down along the needle cam and the stitch cam of the cam block in the course of passing under the respective feeders, In this process, each needle 30 creates a new loop using the yarn fed from the feeder. For example, if there are four feeders, each needle 30 will make four new loops during one revolution of the cylinder.

The jaw 40 is provided at the lower portion of the needle 30 and serves to move the needle 30 up and down. The jaw 40 includes a cam butt 42, a control butt 44, and a butt 42 A spring 46 protruding in the opposite direction, and the like.

The control butt 42 is a portion moving along a rising or falling path provided by a jack lift cam (not shown in the figure), and the control butt 44 is a portion for controlling the operation of the jack 40 Not shown) are contacted by the control projection. The matrix is installed so as to selectively press the control button 44 of all the jacs 40.

The operation of the jacques 40 can be individually controlled by the matrix, and thus the jacques 40 are mainly used when operating a plurality of needles 30 in a complicated pattern to form patterns or patterns on the knitted fabric.

In the general knitting section, the needle 30 is usually raised and lowered only by the cam block. Alternatively, the jerk 42 may be lifted and lowered along the jack lift cam without using the cam block, or the jack 42 may be lifted It is possible to proceed with knitting. Patterns, patterns, and the like are formed, the jets 42 of the corresponding section are individually controlled through the matrix control, thereby elevating and lowering the needle 30 thereon in many cases.

As shown in FIG. 2, when the needle 30 is raised while the old loop 62 is formed, the latch 33 is opened downward by the sphere loop 62. As shown in FIG. When the needle 30 is lowered, the thread 60 is hooked on the hook 32. When the needle 30 is continuously lowered, the sphere loop 62 pushes the latch 33 upward, At the same time, a new loop 64 is formed. As the entire needles 30 repeat this process, loops are continuously connected to each other to knit, and the knitted fabric is lowered downward through the inside of the cylinder 10 and wound on a predetermined winding roller.

However, since a plurality of loops are continuously connected to each other in such a manner, the knitted fabric has a disadvantage that the loops are easily broken when the loop is broken in the middle. Especially in stockings knitted into very thin yarns, these loosening phenomena frequently occur.

Meanwhile, in recent years, in order to increase the convenience of stockings which are uncomfortable to wear and take off, there are more cases of forming holes for various purposes in stockings. For example, as shown in Patent Document 1, there is a case in which a hole for poultry or ventilation is formed in a panty portion of a stocking, a case in which a ventilation hole is formed in a foot portion of a stocking, have.

However, in order to form such a hole in a stocking, which is a knitted fabric, it is necessary to additionally perform additional sewing work (for example, overlock) in order to prevent loosening after cutting the corresponding portion, thereby lowering the productivity, there is a problem. This problem may occur not only in stockings but also in the case of putting holes in other kinds of knitted fabrics, so it is necessary to prepare an improvement plan.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

The present invention relates to a method for knitting a hole with a closed structure at a desired position during a knitting process. It is to be noted that the drawings attached hereto are only shown for the sake of convenience of description and understanding, and thus the scope of the present invention should not be limited thereby.

FIGS. 3 and 4 are respectively a conceptual view and a photograph showing a state in which a hole 102 is formed in a knitted fabric (e.g., stocking) by a knitting method according to an embodiment of the present invention.

As shown in the drawing, according to an embodiment of the present invention, a hole forming area 100 is set in the middle of a general knitting area 200 where knitting is performed in a general manner, and a hole 102 is formed in the hole forming area 100, And closing tissues 110, 120, and 130 around the holes. The knitting process of the general knitting area 200 and the knitting process of the hole forming area 100 proceed continuously without interruption.

The hole forming region 100 may include a first finishing structure 110 and a second finishing structure 120 respectively formed on the lower and upper portions of the hole 102 to prevent loosening, And a third finishing structure 130 formed at both ends of the two finishing tissues 110 and 120 to prevent loosening at both sides of the hole 102. [

The position and the purpose of the hole 102 are not particularly limited. For example, for ventilation or foot removal from the sole of a stocking or the like, or for use in a panty part of a stocking. The tights may be formed at the upper end of the body stocking for sandwiching the arm at a position adjacent to the band portion, or may be formed for various purposes in various other positions.

As shown in the flowchart of FIG. 5, a method of forming a hole according to an embodiment of the present invention includes a step ST11 for performing general knitting, a step ST11 for forming a first finishing structure 110 at a lower portion of the hole 102, A step ST12 of forming a third finishing structure 130 on both sides of the first finishing structure 110, a step ST13 of forming a hole 102 at a predetermined position, (ST14) of forming the second finishing structure 120 on the upper side of the first finishing structure 120 and continuing to form the third finishing structure 130 on both sides of the second finishing structure 120, (ST15).

The method of knitting according to an embodiment of the present invention includes a cylinder 10, a plurality of needles 30 inserted into the outer surface of the cylinder 110, a jig 40, And a plurality of feeders supplying the yarn. However, since the kind of knitting machine is not necessarily limited to the knitting machine, it is also possible to implement the method according to the present invention by using a different kind of knitting machine.

Hereinafter, the process of forming the holes 102 in the knitted fabric according to the embodiment of the present invention will be described in detail with reference to the flowchart and reference diagram of FIG.

First, the general knitting area 200 is knitted by a general method. In this case, as shown in the conceptual diagram of FIG. 6, as the cylinder 10 rotates, all the needles 30 move up and down in the respective lower portions of the first to fourth feeders 1F, 2F, 3F and 4F The loop is repeatedly formed. At this time, the needle 30 generally moves up and down along the needle cam 70 and the stitch cam 80 constituting the cam block. However, by moving the jaws 40 up and down while the cam block is retracted, The needle 30 may be raised or lowered.

On the other hand, when the knitting is to be performed on the general knitting area 200, the yarn is supplied to all of the first to fourth feeders 1F, 2F, 3F and 4F. Therefore, every time the cylinder 10 makes one revolution, ) Form the four loops. (ST 11)

When the knitting reaches the course corresponding to the hole forming region 100 after the general knitting progresses, knitting of the first finishing structure 110 starts and at the same time, the third finishing structure 110 130).

At this time, it is preferable that the needles 30 are lifted and lowered by the jacs 40 individually controlled by the matrix with the cam blocks retracted. The finishing tissues 110, 120, and 130 require more complex needle control than normal knitting.

FIGS. 9 and 10 are conceptual diagrams and knitting state diagrams showing a process of knitting by a knitting method according to an embodiment of the present invention, respectively. For reference, in FIG. 9, one loop formed during knitting is represented by one circle. Thus, when only one circle is displayed over several courses, it means that the first course and the last course of the corresponding section are bundled into one loop.

According to the drawing, 54 needles 30 are used for knitting of the hole forming area 100, and the middle 26 needles (15 to 40 needles shown at the bottom of the figure) are used for forming the first and second finishing tissues 110 and 120 And each of the 14 needles (1 to 14 needles, 41 to 54 needles) on both sides are used to form a third finishing tissue 130 on both sides of the first and second finishing tissues 110.120.

That is, in the general knitting area 200, the knitting is progressed by, for example, 400 needles 30 in a usual manner, and when reaching the course corresponding to the hole forming area 100, 120 and 130 and the holes 102 are formed in the hole forming region 100 while the remaining 346 needles are knitted in a conventional manner.

However, the number of the needles 30 used for knitting the hole forming region 100 is not limited to that shown in the drawings, and may vary depending on the width of the holes 102 and the closed structures 110, 120 and 130.

On the other hand, in the embodiment of the present invention, as shown in the conceptual diagram of Fig. 7, when the hole forming region 100 reaches the course to be knitted, for example, yarn feed of the first feeder 1F is stopped, So that the entire needle 30 does not rise at the lower portion of the needle 1F. Accordingly, the entire needle 30 passes through the lower portion of the first feeder 1F in a state in which the yarn supplied from the fourth feeder 4F is hooked on the hook.

Therefore, when knitting is started with respect to the hole forming region 100, the thread provided from the three feeders 2F, 3F, and 4F except for the first feeder 1F is used to feed the first closed tissue 110 and the third The finishing tissue 130 is knitted. Also, in the general knitting area 200 outside the hole forming area 100, normal knitting is performed using the yarn provided by the three feeders 2F, 3F, and 4F. (ST12)

When the knitted fabric is knitted to the hole forming region 100 and reaches the course corresponding to the position of the hole 102, the first finishing structure 110 is completed. On the other hand, Up and down at the lower portion of the first feeder 1F which is not fed.

All the needles 30 are controlled so as not to rise at the lower portion of the first feeder 1F in which no yarn is fed so that all the needles 30 are fed to the fourth feeder 4F to the lower portion of the first feeder 1F in a state where the yarn is lowered by hanging the yarn on the hook.

Therefore, if the yarn supplied from the fourth feeder 4F is hooked and lowered and the 15th to 40th needles are lowered from the lower part of the first feeder 1F to which the yarn is not fed, 15 to 40 needles are empty and empty. The 15 to 40 needles are then completely separated from the loops of the first finishing tissue 110, and thus the holes 102 are formed on the top of the primary finishing tissue.

On the other hand, even when the holes 102 are formed in this way, knitting for the third finishing structure 130 continues on both sides of the first finishing structure 110 and the holes 102. (ST 13)

After the hole 102 is formed in the manner as described above, the second finishing structure 120 should be formed on the top of the hole 102. That is, empty threads 15 to 40 need to feed yarn from the second feeder 2F and start forming a new loop for the second finishing tissue 120. [ At the same time, on both sides of the second finishing structure 120, the third finishing structure 120, which has been advanced, continues to be knitted. In this case, the knitting is continued in the normal knitting area 200 outside the hole forming area 100 by using the yarn provided by the three feeders 2F, 3F, and 4F. (ST14)

When the second finishing structure 120 and the third finishing structure 130 are knitted and the process reaches the end of the hole forming region 100, the second finishing structure 120 and the third By completing the finishing structure 130, the process for the hole forming region 100 is completed. As shown in Fig. 6, yarn supply to the first feeder 1F is resumed and normal knitting is continued by raising and lowering the needles at the bottom of all the feeders 1F, 2F, 3F and 4F. (ST15)

Hereinafter, a specific method of forming the first to third closed tissues 110, 120, and 130 will be described.

The first closing tissue 110 is knitted by, for example, 26 needles (15 to 40 needles), as shown in Figures 9 and 10, wherein the entire course is divided into several sections and knitted in different ways .

In the embodiment of the present invention, the entire course is divided into three sections. For example, the first to third courses of the hole forming region 100 may be referred to as a first section, the fourth course may be referred to as a second section, And the fifth to fourteenth courses were set as the third section.

However, since this is only an example, the number of courses may vary depending on the size of the finishing structure 110, and the number of sections belonging thereto may also vary.

Referring to the drawings, in the first section (1 to 3 courses), each of the needles 30 can be formed by alternating three loops and one loop. That is, the 15 needles corresponding to the first needle of the first finishing tissue 110 form three loops, the 16 needles bundle the first to third courses into one loop, and the 17 needles form three loops And 18 needles can knit the first section in the order of forming one loop by bundling the first to third courses together.

The first section is adjacent to the lower general knitting area 200 of the first finishing structure 110. When the knitted fabric is knitted in this manner, The binding force between the two is increased. And may be more tightly bonded to the upper end of the first closing structure 110, which is then folded downward.

The second section (4 courses) is a section connecting the first section and the third section. In the figure, each needle (15 to 40 needles) forms only one course. However, The number of courses constituting the section may be two or more.

The third section (5 to 14 course) is a section in which the top of the first finishing tissue 100 is knitted so that it can be folded downwardly, and thus has to be long enough to be folded. For example, it is desirable to knit with more courses than the first section.

In the embodiment of the present invention, the adjacent two needles pair in the third section (5 to 14 course) of the first finishing tissue 110 to operate in the same manner. For example, 15 needles and 16 needles corresponding to the first and second needles form one loop by grouping the 5th to 14th courses, respectively, and 17 needles and 18 needles form 10 loops, And 19 needles and 20 needles form one loop by bundling the fifth to fourteenth courses, respectively, and 21 needles and 22 needles form 10 loops each in the course number range, To 14 courses).

When the knitting is performed in this way, a plurality of courses are bundled into one loop by about half of the needles used for forming the first finishing tissues 110, whereby the upper end of the first finishing tissues 110 is pulled downward (4 courses) and the first section (1 to 3 courses).

The second closure tissue 120 is knitted in a symmetrical manner with the first closure tissue 110 at the top of the hole 102, as shown in Figures 9 and 10.

Therefore, even in the case of the second finishing structure 120, it is preferable to divide the entire course into three sections and knit the sections in different ways. However, when the second finishing structure 120 is knit symmetrically with the first finishing structure 110, the first to tenth courses are set as the first section from the hole 102, the eleventh course is set as the second section , And the 12th to 14th courses may be the third section.

As with the first finishing structure 110, the number of courses and sections is not particularly limited in the second finishing structure 120 as well.

Referring to the drawings, the knitting of the second finishing tissues 120 is started by the 26 needles (15 to 40 needles) that have fallen to an empty state in the process of forming the holes 102. [

The first section (1 to 10 courses) of the second finishing structure 120 is a section which is knitted so that the lower end thereof can be folded upward, and therefore has a length sufficient to be foldable.

According to the embodiment of the present invention, in the first section (1 to 10 courses) of the second finishing tissue 120, two adjacent needles are paired to operate in the same manner. For example, in the first section (1 to 10 courses) of the second finishing tissue 120, 15 needles and 16 needles corresponding to the first and second needles form one loop by bundling the first to tenth courses, respectively , 17 needles and 18 needles form 10 loops, respectively, and 19 needles and 20 needles form one loop by bundling the first to tenth courses, respectively, and 21 needles and 22 needles are respectively connected to the course drawer And the knitting of the first section (1 to 10 courses) is progressed in the order of forming ten loops.

When knitted in this way, a plurality of courses are bundled into one loop by about half of the needles used in the formation of the second finishing tissue 120, whereby the lower end of the second finishing tissue 120 is pulled up and folded Is bound to the organization of the second section (11 courses) and the third section (12 to 14 courses) of the upper section.

The second section (11 courses) of the second finishing tissue 120 is a section connecting the first section (1 to 10 courses) and the third section (12 to 14 courses) But it is not limited to this, the number of courses constituting the second section may be two or more.

The third section (12 to 14 course) of the second finishing structure 120 is a section adjacent to the upper general knitting area 200, in which each needle 30 alternately forms three loops and one loop . That is, the 15 needles form three loops, the 16 needles join together the 12th to 14th courses to form one loop, the 17 needles form three loops, the 18 needles form the 12th to 14th courses (12 to 14 courses) can be knitted in the order of forming one loop by bundling them together.

If the third section (12 to 14 course) is knitted in this manner, the structure becomes dense and the knitting is not easily released, and the binding force with the upper general knitting area 200 is increased. Also, the lower end of the second finishing structure 110, which is then folded upward, is also firmly engaged with the upper general knitting area 200.

On the other hand, the third finishing tissues 130 located on both sides of the hole 102 start to be knitted together with the first finishing tissues 110 on both sides of the first finishing tissues 110 and the first finishing tissues 110 Is finished to be knitted even when the hole 102 is formed and continues to be knitted while the second finishing structure 120 is proceeding and is completed when the knitting of the second finishing structure 120 is completed.

9 and 10, in the embodiment of the present invention, among the 54 needles 30 used for knitting the hole forming region 100 for the third finishing structure 130, 15 to 40 needles) are used for each of the fourteen needles (1 to 14 needles, 41 to 54 needles).

In the operation of 1 to 14 needles, when the knitting of the hole forming area 100 is started, 1 needle, 5 needle and 9 needle form loops every 29 courses, and 2 to 4 needles, 6 to 8 needles, The 12 needles each group one to twenty-nine courses together to form a loop, and the needles 13 and 14 form loops per course.

In the operation of the needles 41 to 54, 41 and 42 needles form a loop for each course, 43 to 45 needles, 47 to 49 needles, and 51 to 53 needles each have 1 to 29 courses, And 46 needles, 50 needles and 54 needles form loops per course.

In this way, the third finishing structure 130 is formed with a plurality of sections for combining the first course and the last course of the hole forming region 100 into one loop, and the two sides of the first and second finishing tissues 110, 3 is tightly tightened by the finishing tissue 130, the phenomenon of loosening around the hole 102 can be prevented.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

For example, in the embodiment of the present invention, the finishing tissues 110, 120, and 130 are formed around the holes 102. Since the finishing tissues 110, 120, and 130 are provided to prevent loosening around the holes 102, The finishing organization 110, 120, 130 can be organized in various ways within a range that can be achieved. Therefore, the number of needles for forming the finishing tissues 110, 120, and 130, the knitting pattern, and the like are not limited to the above-described embodiments and can be modified in various ways in specific applications.

As another example, the knitting method according to the present invention is proposed for forming a continuous process of holes and finishing tissues in stockings, hosiery and the like, but it is also possible to use other kinds of knitted fabrics such as sweaters, vests, shawls, It is naturally applicable even when the finishing structure is formed at the same time.

As another example, in the above-described embodiment, the third finishing tissues 130, which tighten the side edges of the first finishing tissues 110 and the second finishing tissues 120, are formed on both sides of the holes 102, The third finishing tissue 130 may be omitted if there is a small risk of knitting or knitting with a strong yarn.

As another example, since the type of knitting machine for forming holes during knitting is not limited according to the method of the present invention as described above, it is possible to manufacture knitted fabrics using various knitting machines such as circular knitting machines, Through the method, holes and finishing tissues can be formed in a continuous process.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention as disclosed in the accompanying claims.
