Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a rubber knitting warp knitting machine for producing pile knitted fabrics, which comprises two needle bars, each of which is assigned at least one knitting bar for the ground yarn, and a knitting bar for the pile yarn. and a knitting bar device.

Known Raschel machines, which work with latch needles that open and close automatically with the thread, each produce one knitted fabric on each needle bar with at least one knitting bar for the ground yarn.

The pile yarn knitting bar alternately feeds the pile yarn to the knitting needles of one needle bar and the other needle bar, so that the pile yarn is knitted into both knitted fabrics.

A knife is then used to separate the pile yarns and thus the knitted fabric.

As a result, the knitting force of the two fabrics with the raised pile on the left side is 5li.
Li, it's going to be a bit of a bit of a bit of a bit of a bit of a bit of a bit of a bit of a bit of a bit of a bit of a bit of a bit of a bit of a bit of a bit of a bit of a bit of a bit.

Conventionally, only one piece of knitted fabric could be knitted when producing a pile loop knitted fabric.

In a known warp knitting machine for knitting pile loop knitted fabrics, a bar equipped with a flange pin is attached to one side of a needle bar.

In this case, the pile yarns are alternately fed to the knitting needles and flage pins.

As a result, a knitted fabric in which the pile loops only protrude to the left side is obtained.

If pile loops are to be arranged on the left and right sides simultaneously or alternately, it is necessary to arrange flange pin bars on both sides of the needle bar.

Warp knitting machines that knit pile loop fabrics without using flage pin bars are also known.

In this case, the ground yarn for ground crochet is fed to even-numbered knitting needles, while the 4-pile yarn is fed alternately to even-numbered knitting needles and odd-numbered knitting needles.

Therefore, the pile loops are entangled in the fabric on even-numbered knitting needles, and are thrown out on odd-numbered knitting needles in subsequent knitting cycles.

The knitting needles are controlled to be forcibly opened and closed by a press bar.

In this case, depending on the knitting bar used, pile loops can also be formed on the left, right or both sides of the knitted fabric.

The height of the left pile loop is approximately related to the pitch of the knitting needles if the knitting structure is determined.

With the above-mentioned warp knitting machines, raised piles can be obtained by cutting in both cases, but in this case a special machine is not necessary, and a large loss of expensive pile material is taken into account. It must be.

Furthermore, it is often the case that all the pile loops or piles cannot be converted to standing piles because the pile loops are not popped out correctly.

The problem of the present invention is to produce pile loop knitted fabric at high working speed.
Moreover, it is an object of the present invention to provide a warp knitting machine which can be knitted so as to provide many variations, and which can form pile loops and raised piles alternately or simultaneously on the same knitted fabric.

In order to solve this problem, starting from a rubber knitting warp knitting machine of the type described at the beginning, each needle bar is provided with a first knitting needle which is fed with yarn in every knitting cycle to form a stitch. and a second knitting needle which is not fed in each knitting cycle in order to form a pile loop. At least one knitting bar for pile yarn is assigned, and the knitting bar for pile yarn is configured to feed pile yarn alternately to a first knitting needle and a second knitting needle of the associated needle bar. .

In this case, one knitting bar for pile yarn is assigned to each needle bar, so that such a warp knitting machine can knit two knitted fabrics at the same time.

This means that it is possible to obtain work speeds that were previously unattainable when manufacturing pile loop knitted fabrics.

In this case, the forcibly controlled closure of the knitting needles, unlike latch needles which are opened and closed by the thread, makes it possible to create a drop stitch in the second knitting needle in order to form a pile loop. enable.

Moreover, the warp knitting machine of the present invention previously required different machines.

To make it possible to manufacture a large number of different pile knitted fabrics having various patterns using a single same type of machine.

For example, in knitting for at least one pile yarn, if the pile yarn is alternately fed to the first knitting needle of one needle bar and the second knitting needle of the other two-needle bar, both knitted fabrics It becomes possible to create pile loops not only on the right side but also on the left side selectively or simultaneously.

Moreover, in this case it is possible to select the height of the pile loop within a larger range on the left side.

Further, it is also possible to alternately feed the yarn to the first knitting needle and the second knitting needle of the same needle bar in knitting for at least one pile yarn.

In this case, both knitted fabrics are knitted very close together, but without influencing each other.

This results in a significant increase in knitting speed.

When the pile yarns are alternately fed onto the first knitting needle of the needle bar to which at least one knitting for pile yarns belongs and the first knitting needle of the other needle bar, by appropriately cutting the pile yarns afterwards, Two knitted fabrics can be obtained that have raised naps on the left side.

In this case, a pile loop can be provided on the right side regardless of the raised pile.

Further, in at least one knitting bar for pile yarn, the pile yarn is alternately applied to the first knitting needle of the associated needle bar and the first knitting needle of the other needle bar or the second knitting needle of one of both needle bars. Yarn feeding is also possible.

This results in, for example, a knitted fabric with alternating pile loops and raised piles on the left side, without loss of pile material due to cutting.0 It is advantageous if the spacing between the needle bars is adjustable.

In this way, if the pile system is fed alternately to the knitting needles of one needle bar and the knitting needles of the other needle bar, the height of the pile loops will increase even if the knitting needles that are alternately fed are almost facing each other. You can choose freely.

□Furthermore, it is also possible for at least two knitting bars for pile yarns to feed different pile loops to the same second knitting needle during the knitting cycle.

This allows the number of pile loops to be doubled without increasing the number of stitches.

In a preferred embodiment of the invention, at least two knitting bars assigned to different knitted fabrics can be driven synchronously by a common drive.

Since substantially the same knitted fabric is usually knitted on both needle bars, the construction as described above can significantly simplify the structure of the machine.

Advantageously, the knitting needle itself has a slider as a closure element.

In this case, it is no longer necessary to provide a buttshaver and a similar control element in the system of the stitch evacuation device in order to forcibly control the closing element.

This allows two knitting bars for ground yarns and two knitting bars for pile yarns to be placed loosely on the stitch evacuation device.

On the contrary, more than five knitting bars can be installed, for example if more than one ground yarn or more than two pile yarns are used per knitted fabric.

Furthermore, if the automatic warp knitting machine has slider needles and stitch escape pieces that extend parallel to each other, it becomes possible to operate the automatic warp knitting machine in the above-mentioned manner.

Furthermore, by controlling the pile yarn knitting bar with a jacquard, any pattern can be given to both knitted fabrics.

The knitted fabrics knitted by the rubber knitting warp knitting machine of the present invention are suitable for paper binding, towels, furniture fabrics, covering fabrics and the like.
