Description

DETAILED DESCRIPTION OF THE INVENTION Summary of the Invention Consists of a weaving machine with a weaving needle or a labia, which is equipped with a catching needle for knitting a weft yarn or fixing the weft yarn by a catching yarn, and the catching needle is used for knitting a weft yarn or fixing the weft yarn by a catching yarn. is configured to capture and pull the thread from the loop as the capture needle moves in one axis, and to release the thread pulled out on that axis as the capture needle moves in the opposite axis. Ru.

The present invention relates to a weaving machine, and more particularly to a weaving machine with a staple or rapier that uses a staple or a labia to insert weaving threads from one side of a woven fabric.

In this type of weaving machine, it is necessary to use the insertion needle to capture the weft yarn present in the textile fabric on the side opposite to the side through which the insertion needle is inserted. In conventional methods, weft yarns are secured by forming a weave loop with the weave yarn or by forming a weave loop with a captured yarn and winding it around the weft yarn.

In these conventional methods, the weaving or weaving of weft yarns or captured yarns is usually carried out using latch needles.

As a result of recent developments in weaving machines, the operating speed of the weaving machine has increased, and therefore the use of latch needles now not only limits the operating speed of the weaving machine, but also increases the speed of the weaving machine due to wear and tear on the latch needles. Stopping also causes restrictions on the operating time.

According to the invention, a catching needle is provided for knitting the weft yarn or fixing the weft yarn by a catching yarn, and the catching needle is provided with a terminal braid portion formed so that when the catching needle moves in the uniaxial direction, the catching yarn is To provide a weaving machine with a binding needle or rapier, which captures the thread and pulls it out of the loop to release the thread pulled out on the axis when the capturing needle moves in the opposite axis direction.

Many features of the invention will be described in detail below with reference to the accompanying drawings.

In FIGS. 1 and 2, the knitting needle 12 is connected to the braided end 14.
The braided end portion 14 includes a hook portion 16 and a groove portion 18, and the groove portion 18 extends diagonally with respect to the binding needle. The terminal end 17 of the hook portion is located within the groove 18 and below the upper surface 19 of the stapler, so that it lies on the upper surface of the stapler and extends substantially perpendicular to the axis of the stapler. The existing weft threads slide along the binding needles and reach the terminal braid part 14 without being captured by the hook parts. However, weft yarn 2
0 exists at an angle to the staple 12 as shown in FIGS. 1 and 2, the weft yarn 20 falls into the groove 18 as it is pulled out along the staple toward its terminal end. , and is therefore captured by the hook portion 16. As a result, it becomes possible to push out the binding needle 12 into the loop to collect the weft yarn, and further to pull out the captured weft yarn from inside the loop and separate it from the loop.

In FIG. 3, a narrow piece of woven fabric 30 is formed on a weaving machine (not shown), where weft threads 32 are woven into loops 33 using staples 12 as previously described. As shown in the drawing, the binding needles 12 are set to reciprocate in the axial direction parallel to the ends of the woven fabric 30. The binding needles 12 are arranged so as to pass above one weft thread 32 moving in the uniaxial direction, and this weft thread 32 is set so as to be pushed by the weft thread insertion needle 39. In order to ensure that the section 40 of the weft yarn extending from the end of the woven fabric to the binding needle 39 passes at a sufficiently oblique angle to the axis of the binding needle to ensure that the section 40 is located within the groove 18, Yarn deflection finger 42 (
(not shown), and this deflecting finger 42 is preferably connected to a flattening device of a weaving machine, and this flattening device is movably installed and engages with the weft yarns to thereby stabilize the weaving machine. As the wefting occurs, the weft threads are moved in the direction of the warp threads, so that portions 40 of the weft threads extend at an acute angle from the edges of the fabric.

When the stitching needle 12 is retracted, it engages the section 40 of the weft thread and pulls it out of the previously threaded loop-forming end 48 of the weft thread to form a knitting stitch.

Then repeat this operation.

In FIG. 4, the weft thread 32 is fixed in a predetermined position by a catching thread 50, and the catching thread 50 is attached to a loop 5 by a binding needle 12.
1 is knitted. The captured thread 50 is guided by a thread guide needle 54. The thread guiding needle 54 is arranged against the edge of the woven fabric 30,
This causes the capture thread to extend at an acute angle from the edge of the fabric.

In use, the binding needle 12 is inserted between the weft thread loops 330 inserted by the binding needles 39 and passes the catching thread 5'0 above and in contact therewith. Upon retraction of the staple 12, the captured thread is pulled out by the staple 12 from the weft thread loop 33 and the preformed loop 51 of the captured needle to form a new loop 51. Repeat this operation.

By using the binding needles 12 described above, the weaving machine according to the present invention can operate at high speed, and furthermore, when using latch needles, the weaving machine can be operated for a much longer time than conventional weaving machines. .
