[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thread heddle used in hand-weaving. More specifically, the present invention relates to a vertical annular yarn heddle comprising a heddle yarn for picking up and hanging a passed warp yarn and a heald bar for further hanging the heald yarn.

[0002]

2. Description of the Related Art Conventionally, a thread heald obtained by entangled the upper part of a rod made of wood or the like and then hanging the thread in a vertically annular shape is well known. (See FIG. 16) A thread-like body having a plurality of loops formed at equal intervals, a rod in which the loops are inserted, and a string for suspending the rod, are used for heald picking (in this specification, a rod-like body is used). Forming a thread heddle with a thread-like body is referred to as heald removal.)
A heddle that facilitates is known. (Utility model application published
(Refer to No. 56-87479)

[0003]

In this kind of yarn heddle, it is not only possible to easily carry out hedling, but also to make the heald thread (filament) ring after heald removal to have a fixed size. It is required that they are aligned and maintained, and that their positions be maintained on heald bars (bar-shaped bodies) without laterally shifting. In particular, when using this kind of yarn heald in a small-sized hand loom, the warp to be stretched is short, so the opening width is small, and therefore, the size of the above-mentioned loop is made uniform. Is even more important. Further, when weaving a fabric other than a plain weave using this type of yarn heald, the displacement of the heald yarn on the heald bar makes the positional relationship unclear, which is a serious problem. However, it is difficult to say that any of the thread healds described in the section of the related art sufficiently satisfies the requirements. That is, in the former, the yarn is tangled and difficult to handle, not only is it difficult to remove the heald, but also the size of the loop of the heald yarn tends to be irregular, and the position cannot be maintained properly on the heald bar. there were. In the latter case, although the above-mentioned drawbacks have been considerably improved, the loop provided in the filament has a drawback in that the higher the density of the warp and the thinner the warp, the more the hook is caught by the warp and makes the work difficult. Had. On the other hand, even though the thread healds shown in the section of the prior art are used for weaving plain weaves, it is almost impossible to weave other weaves. there were. In other words, the conventional one is suitable for picking up every other warp yarn and hanging it on the heald yarn,
When it is necessary to pick up every two warp yarns, as in the case of weaving a twill pattern, it is difficult to deal with heald yarns and warp yarns, which is extremely unsuitable. Moreover, in the conventional one, it was almost impossible to compare with the organization chart.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and is easy to compare with a structure chart, and is a simple yarn heald which can be used for weaving not only plain weave fabrics but also other fabrics. It is not only easy to remove the heald, but also the size of the loop of the heald thread is not uneven, and the position of the heald thread is shifted laterally on the heald bar. The aim is to obtain no thread heddle.

[0005]

In order to achieve the above object, the heald bar according to the present invention is provided with fixing means for fixing the heald thread at a required pitch at one end along the length direction. A heald bar, wherein the fixing means comprises a slit. In this case, the heald bar may be cylindrical or prismatic, or may be a long plate-like body which is a form of prism. In addition, the slits are provided at regular intervals, as weaving a plain weave structure. In this case, the pitch of the slit is set to be twice the pitch of the warp or the same as the pitch of the warp. The slits are provided at equal intervals even when weaving another structure. The pitch of the slit in this case is the same as the pitch of the warp. In addition, the slits are provided at irregular intervals as a specially woven structure other than the plain weave structure (the change structure of the plain weave is not included). The pitch of the slit in this case is the same as the pitch of the warp,
A portion without a slit is provided on the heald bar in correspondence with a portion where there is no warp to be picked up, that is, a portion where the upper thread is flying. (In the present specification, the warp to be hanged on the heald yarn, that is, the warp yarn to be picked up is referred to as the upper yarn, and the other warp yarns are referred to as the lower yarn.) Also, the longer the heald bar, the more difficult it is to remove the heald. Those formed in advance in a short length can be used in combination. This connection may be performed by using a separately provided member, or may be performed by itself using, for example, a tenon. Further, the heald thread in the present invention is a heald thread that can be engaged with the slit of the heald bar and fixed to the heald rod, and a mark for indicating the fixing position is provided on the heald thread at a required pitch. It is characterized by becoming. In this case, the pitches of the marks are provided at equal intervals so as to weave those of a plain weave, and at irregular intervals as weaves those of another weave.

[0006]

[Operation] The heald bar and the heald thread are used by hanging the heald thread on the heald rod and fixing them. The heald bar configured to be connectable, after taking the heald, is appropriately connected as necessary to obtain a desired length, and is used in the same manner as the above-mentioned heald bar. The fixing is performed by sandwiching the heald thread in a slit provided in the heald bar. The fixing position is determined by a slit provided on the heald rod and a mark provided on the heald thread. That is, when performing heald picking, heald thread is hung so that this mark always coincides with the slit. These slits and marks not only facilitate the heald removal, but also make the size of the loop of the heald thread hung constant, and also serve to keep the heald thread correctly positioned on the heald bar. This function is more important than the case of weaving a simple fabric such as a plain weave, as it is necessary to keep the heald thread in a predetermined position in an orderly manner as the structure becomes higher, for example, a twill weave structure.

Next, the pitch of the slit and the texture to be woven will be described. Heald bars in which the slits are provided at equal intervals at twice the pitch of the warp yarns are used when weaving plain weaves. In this case, the heald yarn used is one in which marks are provided at equal intervals. (See FIG. 1 and FIG. 11) Since the heald bars provided with the slits at the same pitch as the pitch of the warp and at equal intervals can fly the heddle by skipping every other slit, the same as above, Used when weaving plain weave tissue. (See FIGS. 5 and 11)
Further, since the heald bar can arbitrarily fly the slit and hang the heald thread, it is preferably used for weaving other fabrics in addition to plain weave. It can also be used when weaving. (See FIG. 3, FIG. 5, FIG. 6, FIG. 12, FIG. 13, and FIG. 14.) Further, the slits correspond to the structure of the woven fabric to be woven and have the same pitch as the pitch of the warp and unnecessary portions. The heald rods provided at unequal intervals are used as specially woven heald bars. In this case, the heald yarn used is one in which marks are provided at irregular intervals. (FIG. 3,
(See FIGS. 6, 12, 13, and 14)

Next, a procedure for heald removal will be described with reference to the drawings. (Refer to FIG. 15) First, the upper yarn k1 and the lower yarn k are formed by using a thin plate or the like (not limited to a simple structure) while comparing the warp stretched in advance with a structure diagram.
Divide into 2 counties. In this case, the warp to be picked up corresponding to the texture point (or non-texture point) of the woven fabric is divided into the upper thread k1 and the other thread is divided into the lower thread k2. Next, a heald thread h is inserted into the opening from one end (in this case, from the right) using a tool such as a thin plate, and the heald bar a previously held upward is sequentially inserted from the other end (in this case, from the left). Heddle thread h
And fix it. The heald thread h is always the upper thread k1 and the upper thread k
1 and is wound around the one end of the heald bar a in a constant direction (in this case, from the front side) in a winding manner. At this point, the warp thread, that is, the upper thread k1, is independently introduced into the loop of the heald thread h. When weaving other fabrics such as twill weaves other than plain weaves, heald yarns h are simply wound only in those portions where the upper thread does not fly. (See FIGS. 3, 6, 12, 13, and 14)

As described above, in the case of weaving a yarn heald for which heald removal has been completed, for example, with a plain weave structure, the shed can be opened by alternately pulling up the two healds. When weaving a regular oblique weaving structure such as a four-layer twill with another structure, weaving can be performed by using four of them and pulling them up in a certain order.
However, as can be seen in certain types of ground equipment, the opening of the middle cylinder can be combined with the opening of the thread heald, so that the number of healds can be reduced by one.
That is, it can be performed with one heald in plain weave and three yarn healds in four twill.
