Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of knitting a floating handle in a warp knitting machine, and more particularly to a knitting method which can obtain a so-called drop plate effect (formation of a fall plate wrap) without using a drop plate.

[0002]

2. Description of the Related Art Conventionally, in a warp knitting machine, it is common practice to form a base fabric with a base yarn and to form a handle on the base fabric with a handle yarn. It is also well known that a pattern is expressed by a sinker pattern formed by a pattern and a float pattern in which a pattern thread is floated on a base cloth.

Regarding the floating pattern among the above, a pattern reed for knitting the floating pattern is arranged in front of the ground reed for knitting the ground yarn, and the pattern reed is overlapped with the ground reed and guided by the pattern reed. A floating pattern is formed on the surface of the base cloth by moving only the thread to be floated to the knitting needle position where the needle loop (stitch) cannot be formed by the fall plate (fall plate) The yarn is fixed by a so-called fall plate wrap regardless of stitches.

However, in the knitting of the above-mentioned warp knitting machine with a falling plate, the raising and lowering motion of the falling plate is essential, and the existence of this falling plate has been a cause of hindering the increase in the rotational speed of this type of knitting machine.

On the other hand, a method of producing a drop plate effect without using a drop plate is proposed in Japanese Utility Model Publication No. 39-19271. The gist of this is to use a knitting needle with a vertically movable pipe needle that has a hook at the tip and a mandrel that opens and closes the hook, and provides a ground reed and a floating reed as separate reed main bodies. The reed main body is made to move under different reciprocating rotation loci in the upper part of the knitting needle row.

In this case, since the knitting needle row only moves up and down and the knitting needle is a so-called pipe needle, an excessive friction phenomenon occurs on the knitting needle due to the unidirectional pulling down force of the floating yarn on the knitting needle due to the floating reed. There is a possibility that the floating yarn that has been hung on the knitting needle is not smoothly transferred to the lower portion of the knitting needle, and that the yarn is broken because the load on the floating yarn is large.

For this reason, up to now, knitting has been carried out using a conventional drop plate, which has a certain action, not only improving the number of revolutions.

[0008]

DISCLOSURE OF THE INVENTION The present invention provides a knitting method which solves the above-mentioned drawbacks and can smoothly form a fall plate wrap without using a falling plate in knitting a floating handle by a warp knitting machine. It is something to do.

[0009]

SUMMARY OF THE INVENTION A method of knitting a float according to the present invention which solves the above-mentioned problems, comprises a needle and a tongue which slides in a side groove of the needle, and at least a compound needle arranged in parallel along a trick plate. It has a ground reed for feeding the ground yarn, and a floating reed for feeding the floating yarn for forming the floating handle,
A warp knitting machine in which a compound needle performs a combined motion of linear motion and rocking in the needle length direction is used.

First, the needle is projected from the trick plate and swung in while moving in the direction of the ground reed, and after passing through the part of the ground reed, the needle is retracted and / or the tongs are projected in the direction of projection while continuing the swing. Close the hook with the tongue by sliding it a little to the end, wind the float yarn around the tongue, and while swinging out the needle, slide the needle and / or tongue in the opposite direction and hook again. Is opened, the ground yarn guided by the ground reed overlaps the needle, and the hook is closed by pulling in the needle while swinging out to form a stitch, and these steps are repeated to knit.

In the above, it is preferable that a projection is provided at the tip of the tongue so that the wound floating yarn is held in a wound state because the holding is ensured.

[0012]

[Operation] According to the above-mentioned method of the present invention, the needle is projected from the trick plate and moved in the ground reed direction while passing through the ground reed portion by swing-in, and then the needle is slid in the retracting direction or the tongue is moved. The hook is closed with the tongue by sliding the protruding direction of the tongue, or both of them, and the floating yarn is wound around this tongue, and then while swinging out, the needle and / or
Alternatively, since the tongs are slid in the opposite direction to open the hooks again, the float yarn wound around the tongs is wound around the tongs without excessive tension being applied, and the stitches of the needle are The fall plate wrap is smoothly moved to a position where it is not formed, and the fall plate wrap is formed with the stitch forming action by the next overlap of the ground yarns.

In particular, when the tongue of the compound needle is provided with a projection at the tip, the floating yarn wound around the tongue is removed from the tongue by the positive opening action of the hook by the needle and / or the slide of the tongue. It is held in a wound state without separating, and the above-mentioned floating pattern knitting is reliably performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a knitting method of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic side view of a knitting essential part of an example warp knitting machine used for carrying out the knitting method of the present invention. In the figure, 1 is a needle having a hook 1a at its tip, 2
Is a tongue that fits and slides in a side groove 1b that is open to the rear side of the needle 1. The needle 1 and the tongue 2 form a compound needle. The compound needles are juxtaposed along the trick plate 10.

Reference numerals 3 and 4 are ground reeds for feeding the ground yarn, and 5 is a floating reed for feeding the floating yarn. The floating reed 5 is located in front of the ground reeds 3 and 4 (on the left side of the drawing), and the multiple rows of the floating reed 5 are mounted on a support frame (not shown) and supported by the support shaft 6. And is provided so as to be capable of swinging movement in the direction indicated by arrow 7. Further, 8 is a sunken pattern reed, which is mounted on a support frame (not shown) different from the floating reed 5 together with the ground reeds 3 and 4 and is supported on a support shaft 9, but is fixed to the support shaft. The rocking motion is not performed in the closed state.

The needle 1 and the tongs 2 swing together with the trick plate 10 in the front-back direction of the knitting machine, and are independently linearly moved in the needle length direction, that is, in the protruding and retracting directions by the cam mechanism (in the case of the figure). Lifting motion) is performed. In particular, the needle 1 slides slightly in the retracting direction at the front side of the ground reed 3 at the front side of the ground reed 3 as shown in the locus of movement shown by the curve 16 in the drawing, and again in the protruding direction at the backswing after the floating yarn is wound. It is provided to perform a sliding motion. The swing of the floating reed 5 is performed corresponding to the movement of the needle 1. Since a series of these movement mechanisms are well known, illustration and description thereof will be omitted.

Next, a specific method of knitting a floating pattern by the warp knitting machine will be described with reference to the schematic side views of the knitting main parts showing the respective knitting steps of FIGS. In the figure, 11 is a floating yarn, 12 and 13 are ground yarns, and 14 is a sinking yarn.

FIG. 2 shows a needle 1 and a tongue 2 of a compound needle.
Both are at the starting point position accommodated in the trick plate 10, and have just finished knockover (a state in which the new loop escapes from the old loop). At this time, the floating reed 5 is at the end position of the swing, and the ground reeds 3 and 4 and the sunken reed 8
Is in the underlap. Float reed 5 also underlaps.

In FIG. 3, the needle 1 is the trick plate 1.
Sliding in the direction of ground reed 4 protruding from 0 (ascended in the figure)
When the compound needle (needle 1 and tongue 2) and the trick plate 10 start swinging in, that is, front swing (forward swing) in the direction of arrow 15, as shown in FIG. As the movement locus indicated by the curve 16, it passes through the reed portions of the ground reeds 3 and 4 and the sinker reed 8.

After passing through the reed portion, the needle 1 once slides in the pull-in direction (downward in the figure) while continuing to swing, and slides in the protruding direction (upward in the figure) separately from the needle 1. The tongue 2 closes the hook 1a. On the other hand, the floating reed 5 is swung in the direction of the arrow 17, that is, the direction of the ground reed 3, and swings in to the compound needle, and the needle 1 also passes through the portion of this floating reed 5.

FIG. 4 shows a state in which the float reed 5 has swung in and reached the overlap position, and at this time, the needle 1 and the tongue 2 are both in the turning position of the swing motion. In this state, the floating pattern reed 5 forms an overlap after swing-in, and the floating pattern yarn 11 is wound around the tongs 2. At this time, the tongue 2 is in a state in which the hook 1a of the needle 1 is closed as described above. After this, float reed 5
Is swung in the direction of arrow 18.

FIG. 5 shows a state in which the float pattern thread 11 is wound around the tongue 2 by overlapping, and the float pattern reed 5 continues to swing out in the direction of arrow 18. At this time, the compound needle starts swinging out, that is, backswing (swing backward), and the needle 1 again moves upward in the direction of the arrow 19 (tongue 2 does not move), and the positive opening movement of the hook 1a. Is performed.

FIG. 6 shows that the floating yarn 11 wound around the tongue 2 is moved to the needle 1 by the positive opening movement of the hook 1a caused by the slide of the needle 1 in the protruding direction indicated by the arrow 19 in the previous figure, that is, the upward movement in the figure. On the other hand, the state in which the stitches on the base side are not formed is shown. At this time, the float pattern reed 5 is wound around the tongs 2 by a combined action of the downward swinging motion of the float reed 5 indicated by the arrow 18 and the positive opening motion by the sliding of the needle 1 in the protruding direction. In this state, the needle 1 is held in the open state and is smoothly transferred to the base side of the needle 1 that has re-projected, that is, raised in the figure. Therefore, excessive tension is not applied to the float yarn 11.

Thereafter, the needle 1 further swings out in the direction of arrow 20, that is, backswings,
After the ground reed 3 overlaps the needle 1 having the hook 1a opened, the motion is continued.

FIG. 7 shows a state in which the needle 1 continues its backswing in the direction of arrow 20 with respect to the sunken handle reed 8 and the ground reed 4, after which the hook 1a is closed by the tongs 2 as the needle 1 is retracted. Knock over and return to the knitting position in FIG.

By repeating these steps, the fall plate wrap is smoothly formed without using the falling plate, and the floating pattern is knitted.

As shown in FIG. 8, a projection 2a is formed on the tip of the tongue 2 to securely hold the floating yarn 11 wound around the tongue 2 at the knitting position in FIG. The back swing causes the floating thread 11 to hook 1.
It does not enter the opening of a. That is, by doing this, the floating yarn 11 can be placed in the correct knitting state.

In the above embodiment, the floating reed 5 is provided so as to be capable of swinging, and the floating reed 5 is swung to swing into the needle 1 and the floating thread 11 is wound around the tongue 2. Although the case of swinging out afterward is shown, it is also possible to knit the floating reed without swinging it against the needle, or to knit with both floating and non-swing floating reeds. It is possible.

For example, FIGS. 9 and 10 show ground reeds 3 and 4.
And a part of a knitting process by a warp knitting machine in which a required number of floating reeds 5a that swing and a number of floating reeds 5b that do not swing are arranged in front of the sunken pattern reed 8 so as to correspond to the movement locus of the needle 1. Is shown. Other configurations are basically the same as those in the above-described embodiment. Reference numeral 21 is a reed for supplying the reinforcing yarn of the base cloth.

The floating stalks 5a and 5b can be mounted on a bearing frame and supported on the same bearing shaft, or can be supported on another bearing shaft.

In this embodiment, FIG. 9 corresponding to FIG.
In this state, the needle 1 and the tongue 2 are at the starting position and knocking over is completed. From this state, the needle 1 slides in the projecting direction and starts the swing-in, that is, the front swing in the direction of the arrow 15, and the needle 1 moves to the ground reeds 3 and 4 and the sinker reed 8 as shown by the movement locus indicated by the curve 16. Pass through the reed part.

After passing through the reed portions, the needle 1 slides in the retracting direction a little while continuing the swing to close the hook 1a with the tongs 2 and the needle 1 moves, as in the above-described embodiment. After passing through the portions of the floating reed 5a that swings and the floating reed 5b that does not swing, the floating reed 5a swings in the direction of the arrow 17a and moves to the overlap position with respect to the needle 1.

FIG. 10 shows a state in which the needle 1 has reached the folded position, the floating reeds 5a and 5b are in the overlapping position, and both reed rows are overlapped. In this state, the floating reeds 5a and 5b overlap each other and the floating yarns 11 are wound around the tongs 2.

Thereafter, the needle 1 slides in the protruding direction again and performs a backswing, whereby the floating reeds 5a, 5
The hook 1a is opened by sliding the needle 1 while passing the portion b and holding each floating yarn 11 wound around the tongue 2. As a result, the floating yarn 11 wound around the tongue 2 moves to a position where it does not enter from the opening of the hook 1a.

Thus, after the reeds 3 and 4 overlap, the needle 1 sinks and the backswing continues with respect to the handle reed 8 and the reeds 3 and 4, and the hook 1a is closed by sliding the needle 1 in the retracting direction. It returns to the state of FIG. 9 and knocks over. The floating reed 5a swings in the direction of arrow 18a and returns to the underlap position in FIG.

By repeating these steps, the fall plate wrap can be smoothly formed without using the falling plate, and a desired float can be knitted, as in the above-described embodiment.

In the embodiments of FIGS. 9 and 10 described above, the case where the floating reed 5a on the side closer to the ground reed 3 is swung is shown. On the contrary, the floating reed in FIG. 10 is used. 5
A is fixed at the overlap position, and the floating reed 5b
Can be swingably provided so as to swing into the overlap position.

When the floating reed 5 is carried out without swinging, the floating reed 5 swinging in FIGS. 9 and 10 is used.
Except for a, only the floating pattern reed 5b that does not swing may be arranged, and the floating pattern can be knitted in the same manner as described above.

That is, the needle 1 slides slightly forward in front of the ground reeds 3 and 4 and the sunken pattern reed 8 in the retracting direction during the front swing, and again in the protruding direction during the backswing after the floating yarn is wound. Since the sliding motion is performed, by utilizing this motion, the floating reed 5b is arranged so as to correspond to the movement locus of the needle 1 in front of the ground reed 3, so that the hook 1 is slid by the sliding motion of the needle 1. The floating thread can be wound around the tongue 2 that closes the la 1 without swinging the floating reed.

When a large number of floating reeds are required due to the construction of the pattern, both floating reeds that swing and those that do not swing are used together as in the above-described embodiment, and both reed rows are arranged. It is preferable that the floating yarns are overlapped and juxtaposed in parallel at the overlap position because the timing of winding the floating yarn with respect to the tongs can be easily adjusted. Further, when the floating pedestal is swung, the above-mentioned movement of the needle can be utilized, so that the swinging motion of the floating pedestal can be small.

In each of the above-mentioned embodiments, the ground reed and the sunken pattern reed are not swung, but of course both can be swung.

Regarding the positive opening movement of the hook by the needle and the tongs, in the above-mentioned embodiment, although the opening accompanied with the sliding of the needle 1 in the protruding direction, that is, the upward movement is shown, the tongue 2 is pulled in the drawing direction. It may be performed by sliding or lowering, or may be performed by a combined action of the slide of the needle 1 in the protruding direction and the slide of the tongue 2 in the retracting direction.

Further, the method of supporting the floating reed and the ground reed is not limited to the two supporting shafts as described above, and a single one can be used. If all are fixed and do not swing, the supporting shafts can be used. It is also possible to use only the support frame instead.

According to the present invention, even in the case of a warp knitting machine in which the constituent parts of the warp knitting machine shown in the figure are left as they are, and the whole is inclined or laid sideways at a desired angle, It goes without saying that the floating pattern can be knitted in the same manner as.

[0046]

The knitting method of the float according to the present invention uses a warp knitting machine in which a compound needle consisting of a needle and a tongue that slides in the side groove of the needle performs a combined linear and oscillating motion in the needle length direction. Therefore, as a result of the opening movement by the needle of the compound needle and / or the slide of the tongs, the floating thread wound around the tongs is smoothly transferred to the base side of the needle,
Excessive tension is not applied to the float yarn, and as a result, breakage of the float yarn due to over tension does not occur.

Further, since it is not necessary to equip the knitting portion with a driving device such as a conventional drop plate, the number of knitting can be increased as a result, and when the floating yarn and the ground yarn are overlapped from the same direction. In the case of the fall plate wrap, the drop of the ground thread due to the action of the conventional drop plate is eliminated, that is, the drop of the ground thread caused by the pushing down of the floating pattern yarn applied to the same needle position as the ground thread by the drop plate is eliminated. There is no restriction in knitting, and it is possible to knit a knitting structure suitable for the purpose of a race in terms of knitting structure.

As described above, according to the knitting method of the present invention, the falling plate is swept away from the conventional warp knitting machine equipped with the falling plate, the productivity is improved, and the production of higher quality warp knitted fabric is possible. Has an epoch-making effect.
