Description of the Related Art Conventionally, a feeding device of a loom adjusts a warp tension by changing a position of a tension roll while a warp sent from a feed beam is wound around a tension roll. The tension roll is a member that passes through in the width direction of the loom, and needs sufficient rigidity so as not to be largely bent by its own weight and not to be deformed by warp tension.

る。[0003] In the weaving process, the warp tensions of sheet-like warps are all set to target tensions. However, at the time of actual weaving, a portion having a high tension and a portion having a low tension may be unevenly generated in the weaving width direction. When the tension roll having the rigidity as described above is displaced in a state in which the warp is wound in a state where the tension unevenness of the warp in the weave width direction, that is, the target tension is uneven in the weave width direction, the tension roll is Since the position is changed corresponding to the portion where the warp tension is high, the warp becomes loose at the portion where the warp tension is low. as a result,
Distortion of the warp, fluff, and the like are likely to occur in a portion where the warp tension is low, which is a factor that significantly reduces the operation of the loom.

り経糸に圧接させている。According to the present invention, there is provided a warp tension adjusting device for a loom for feeding a sheet-like warp from a delivery beam through a tension roll before weaving. On the path, at least one tension adjusting means displaceable partially against the elasticity in the weaving width direction is arranged over the entire weaving width direction, and this tension adjusting means is pressed against the warp over the entire weaving width direction. .

That is, the tension adjusting means is partially displaced largely in a portion where the warp tension is high, and is displaced small in a portion where the warp tension is low. Therefore, even if the warp tension unevenness occurs in the weaving width direction during weaving, the tension adjusting means absorbs the warp tension unevenness by its own elastic displacement, and the warp tension in the weaving width direction is partially reduced. Prevents loosening and keeps warp tension almost uniform.

At least one tension adjusting means 15 is pressed against the warp 2 over the entire region in the weaving width direction. In this specific example, the tension adjusting means 15 is constituted by an elastic member 16, and is supported at both ends by a pair of left and right brackets 20. The elastic member 16 is a member capable of being partially elastically deformed in the vicinity of the pressed portion by being pressed against all the sheet-like warps 2 and receiving warp tension, and in a portion having a high warp tension in the weaving width direction. It is largely deformed, and is slightly deformed in a portion where the warp tension is low.

好ましい。The material used for the elastic member 16 is not particularly limited as long as it undergoes the above-mentioned elastic deformation and there is no danger of breakage. For example, in addition to a leaf spring, a thin plate, a thin round bar, plastic, and the like, It is composed of a combination or the like. The contact portion (contact surface) of the elastic member 16 with the warp 2 is preferably formed into a smooth shape so as not to damage the warp 2 or subjected to a surface treatment so that the warp 2 is slippery.

Is adjusted so as to be displaceable and passively displaced to a position where the biasing force of the spring 14 and the warp tension are balanced. For this reason, the warp tension of the sheet-like warp 2 should be set to the target tension. However, due to the yarn physical properties and the variation in the gluing, the warp tension is not uniform in the weaving width direction, and the warp tension may not be high. Low parts may occur.

毛羽等が発生しにくくなり、織機の稼働が向上する。At this time, the elastic member 16 partially elastically deforms largely in a portion where warp tension is high, and partially elastically deforms in a portion where warp tension is low. Therefore, even if the unevenness of the warp yarn 2 occurs in the weaving width direction during the weaving, the elastic member 16 partially absorbs the warp tension unevenness by its own elastic deformation in the weaving width direction. The warp tension is adjusted to a substantially uniform warp tension by preventing a partial loosening of the warp tension. Therefore, the warp 2 is less likely to be disturbed or fluffed in a portion where the warp tension is low, and the operation of the loom is improved.

式もある。As shown in FIG. 1, in general, the tension roll 5 is supported in a displaceable state, and the tension roll 5 is passively displaced to a position where the urging force of the spring 14 and the warp tension are balanced to adjust the warp tension. Do. This form is a passive easing mechanism. The easing mechanism is not limited to the above-described negative easing mechanism, but also includes a positive easing mechanism in which the swing lever 11 is positively displaced by the driving means, or a combined easing mechanism in which the negative easing mechanism and the positive easing mechanism are combined. The type of support of the tension roll 5 is not limited to the easing mechanism, and there is also a type in which the warp tension is adjusted by adjusting the amount of the warp 2 delivered from the delivery beam 3 without displacing the tension roll 5.

い。The method of attaching the elastic member 16 is not particularly limited. The elastic member 16 is not necessarily a continuous body in the weaving width direction but may be divided into a plurality as long as the elastic member 16 is constantly pressed against the warp 2 in the weaving width direction. However, it is preferable to use a member having a uniform cross-sectional shape in the weaving width direction.

An example in which a plurality of elastic members 17 are supported in the weaving width direction, a support housing 18 supporting these members, and a contact member 19 in contact with the warp 2 is shown. A large number of elastic bodies 17 are coil springs or the like, and are attached to the inside of the support housing 18 at one end and are independent at regular intervals in the weaving width direction, and at the other end are common to all the elastic bodies 17. Book contact 1
9 is fixed. Here, the contact body 19 is slidable inside the support housing 18 and partially deforms in the weaving width direction against the corresponding elastic body 17.

The contact bodies 19 in the divided state are connected in a diagonal joint or (joint joint) form so as to be continuous at the division position in the weaving width direction. For this reason, the warp yarn 2 does not enter the seam of the contact body 19. Needless to say, the joining type is not limited to the above, and it can also be formed by an irregular joint (joint joint), a board joint, or the like.

Even if the warp tension unevenness occurs in the weave width direction, the warp tension unevenness is absorbed by displacement or deformation of the tension adjusting means, and partial loosening of the warp tension in the weave width direction can be prevented. Thereby, the warp tension can be maintained substantially uniform in the weaving width direction.
