Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a knitting device for lace, particularly for multi-guide bar lace, which includes multiple thread movements.

Conventionally, multi-guide bar lace machine (multi-guide bar lace machine)
A typical example of this is the river lace machine, but there is also the raschel lace machine, which is knitted with latch needles.

However, in Raschel lace machines that use bellow needles,
The number of guide bars developed based on the current organization mechanism is 60.
The number of guide bars on the side bottom was not even close to that of a single handle guide bar on a river lace machine, and it was impossible to form complex ground textures and handle areas.

Therefore, as a solution to the above-mentioned drawbacks,
-28987 has already been proposed, but due to its knitting mechanism, only a single row of sorting pieces can be provided to guide the ground yarn for knitting the ground texture against the pattern yarn. In addition to being unable to provide double rows of ground thread guide pieces necessary for moving the ground threads relative to each other, such as in a power net fabric structure, it was also impossible to perform thread removal, etc., which required stitch formation.

In addition, it was not possible to form stitches over several needles, and only a limited number of stitches could be formed in terms of texture.

This invention was originally filed in a patent application in 1984 as a solution to the above-mentioned drawbacks.
-69725, a multi-guide bar lace knitting device was proposed, and the present invention is a further improvement of the device, in which multiple rows of stitch-forming thread guide bars for knitting stitch rows are provided independently at the front, and the A group of pattern yarn guide bars for guiding the pattern yarn is provided in parallel, and further behind the group of pattern yarn guide bars there is a needle for guiding the insertion yarn acting on the stitch row of the stitch forming base yarn. A guide bar for inserting ground threads is provided, which is formed by threading the threads in the number opposite to the gauge, and a control member is provided that can control the entry and exit of the threads threaded through the guide bar from a substantially horizontal direction. It is arranged so that it acts between each thread.

Next, the apparatus according to the embodiment of the present invention will be explained in detail based on the drawings. FIG. is a guide bar for the stitch forming ground yarn, and is a chain link or a pattern wheel (none of which is shown).
The needles 1 are slid from side to side in the row direction of the needles 1 through the needles 1.

Reference numeral 5 indicates a group of guide bars for pattern threads. Each guide bar is made of ultra-thin steel plate, and usually about 200 sheets are arranged, each having a thickness of about 0.15 to 0.2 mm. The wrap is a known jacquard mechanism (not shown)
The tip of the guide bar is provided with thread guiding holes for the pattern thread at regular intervals.

Reference numeral 6 denotes a guide bar for inserting the ground yarn, and the guide bar has thread guide holes equal to the number of needles 1. Reference numeral 7 denotes a control member, which is slidably arranged in parallel with the guide frame 8. Spring 9
is inserted, one end of which is positioned slightly protruding from the lower end of the guide bar 6, and the other end associated with a control edge 10 connected to a jacquard mechanism (not shown).

Reference numeral 11 denotes a comb plate, and a holding bar (not shown) is placed between each needle 1 in a direction perpendicular to the installation line of the needles 1 arranged at regular intervals corresponding to the knitting machine gauge. It is configured to perform reciprocating circulation movement in a plane perpendicular to the row of needles 1.

The above is the configuration of the device according to the embodiment of the present invention.Next, its operation will be explained.In FIG. 14 is a group of pattern threads, each of which is threaded through a group of pattern thread guide bars 5 at intervals corresponding to the width of the pattern.

Reference numeral 15 denotes an inserted ground yarn, which is threaded through the inserted ground yarn guide bar 6, and performs insertion knitting on the stitch rows formed by the stitch forming ground yarns 12 and 13.

2 to 4 are schematic front views of the knitting section showing the process of knitting by the device of the present invention, and the knitting position in FIG. 2 is when the needle 1 is descending, and the needle 1 is first inserted When the ground thread guide bar 6 underlaps in the direction of the arrow,
When the control member 7 selected for the structure structure out of the control members 7 protrudes, the inserted ground thread 15 is bent and becomes the inserted ground thread 15b, while the one that is not acted upon is the inserted ground thread 15.
It becomes a.

Here, the comb plate 11 enters between the inserted ground threads 15 and then descends to press down the inserted ground threads 15 from above,
As shown in FIG. 3, the inserted ground yarn 15 is introduced between the needles 1.

At this time, the guide frame 8, which holds the control members 7 slidably in parallel, can slide on the slide pins 16 and 17 using a pattern wheel or the like (not shown), so that the control members 7 can be moved as shown in FIG. will be located above between needle 1 and the next movement, i.e. needle 1 and knockover plate 2.
When swinging to the position shown by imaginary lines in FIG.

In this way, the inserted ground thread 15 is laid on the stitch forming ground thread 12 together with the pattern thread group 14, and then the inserted ground thread 15 is laid on the stitch forming ground thread 12.
is inserted into the ground tissue by overlapping.

FIG. 5 shows a schematic diagram of the structure of the above-mentioned knitting, in which the inserted ground yarn 15a is inserted back and forth between the two chain stitches for the chain stitch using the stitch forming ground yarn 12, and the inserted ground yarn 15b is inserted into the chain stitch. The control member 7 is appropriately controlled to take in and out the part where the inserted ground yarns 15a pull adjacent chain stitches together and the parallel state of the chain stitches due to the inserted ground yarns 15b in accordance with the pattern configuration of the pattern thread group 14. By doing so, changing network structures of various shapes can be made to appear at desired locations.

As described above, the multi-guide bar lace knitting device of the present invention is capable of individually controlling the inserted ground threads with one guide bar in accordance with the pattern configuration using a group of pattern thread guide bars. Since the number of guide bars for inserted ground yarns that make up the other net weave, which would otherwise require 10, can be unified to one, the space occupied by the guide bars can be reduced, and as a result, the amount of swinging of the needles can be reduced. Since the number of threads can be reduced, a suitable knitting state can be obtained, and a gorgeous and beautiful lace can be knitted by combining the pattern structure of the pattern yarn and various net structures of the ground structure.
