Description

Description: TECHNICAL FIELD The present invention relates to a device for regulating the shape of a woven fabric to a required shape when weaving a three-dimensional woven fabric of unequal cross section.

[Prior Art] With a blade (braid) type three-dimensional weaving machine, it is very difficult to weave a fabric whose cross-sectional shape changes sequentially. The present inventors previously proposed in Japanese Patent Application No. 1-85111 a technique for weaving a three-dimensional woven fabric with unequal cross sections, but such a technique can be used to sequentially change the cross-sectional shape of the woven fabric. Even if possible, depending on various conditions of weaving, for example, the shape of the woven fabric, the tension of the yarn causes distortion, unevenness, and the like, and it is difficult to maintain the desired shape.

In such a case, in order to maintain the shape of the woven fabric, it is necessary to regulate the woven fabric being woven into a final unequal cross-sectional shape, but the regulation is difficult because the cross section is not constant.

[Problems to be Solved by the Invention] A technical problem of the present invention is to fabricate a three-dimensional fabric having an unequal cross section, which is being woven in a three-dimensional fabric weaving device, into a desired shape and hold it. It is to obtain a regulating device, and to obtain a shape regulating device having a simple structure therefor.

[Means for Solving the Problem] A fabric shape regulating device of a three-dimensional woven fabric weaving device of unequal cross section according to the present invention for solving the above-mentioned problem is to carry a carrier of a large number of yarns along a required locus by a carrier driving mechanism. In a weaving device for weaving a three-dimensional woven fabric in which the yarns held by the carrier are made to run together by weaving, and the cross-sectional shape orthogonal to the woven fabric drawing direction changes in the weaving axis direction, the cross-sectional shape of the woven woven fabric Is provided along with the surface of the part that changes, and the contact surface is moved in the weaving direction of the fabric in synchronization with the weaving of the fabric as the weaving proceeds, and the newly weaved part Means for sequentially moving the contact surface that comes into contact with the contact surface to the contact position, and means for removing the contact surface from the surface of the cloth after shaping the cloth having a changed cross-sectional shape into a desired shape. Characterized by It is something.

In the above-mentioned shape regulation device, a regulation caterpillar in which a large number of divided regulation pieces having a small contact surface that partially abuts on the surface of a woven fabric whose cross-sectional shape changes, and a regulation caterpillar, are formed. Of the flexible caterpillar formed around the contact surface that abuts the surface of the fabric, and a multi-plate regulation formed by stacking a large number of control plates with small contact surfaces that partially abut the surface of the fabric A device, or a deformed roller having a contact surface that contacts the surface of the same fabric formed around the device can be used.

A second fabric shape regulating device of the present invention is, in the above-mentioned three-dimensional fabric weaving device, brought into contact with a surface of a portion where the cross-sectional shape of the fabric is changing over a certain length of the fabric being woven. Equipped with a large number of divided contact surfaces, the divided contact surfaces appear and disappear on the side of the fabric so as to be in contact with the surface of the fabric at all times in synchronization with the derivation of the fabric along with the progress of weaving and corresponding to changes in the cross-sectional shape of the fabric. It is characterized in that a means for making it provided. In this fabric shape regulating device, the divided contact surface can be constituted by rollers.

[Operation] When the yarn carrier is made to run along a required locus by the carrier drive mechanism and the yarns held by the carrier are organized into one another, generally, the three-dimensional fabric being woven is not always the desired final fabric. Does not always retain its shape,
In particular, in a three-dimensional woven fabric having an unequal cross-sectional shape, it is difficult to maintain a desired shape due to strain, deviation, etc. due to the tension of the yarns, etc. By controlling the shape, it becomes possible to maintain the woven three-dimensional woven fabric in a nearly final woven fabric shape.

Thus, in the woven fabric shape regulating device, the contact surface adapted to the shape of the woven fabric having an uneven cross section is always brought into contact with the woven fabric surface, and is synchronized with the deriving of the woven fabric as the weaving progresses. The contact surface is moved or deformed, and the newly woven portion is also contacted with the contact surface according to the shape of the woven fabric, so that the woven fabric is reliably shaped into the required shape.

[Examples] Examples of the present invention will be described in detail below with reference to the drawings.

This three-dimensional woven fabric weaving device is provided with a large number of carriers 12 for holding the yarn 1 by applying necessary tension in a large number of rows and columns along a carrier moving surface 11 of a partially cylindrical surface formed by a machine frame 10. By rotating one of the pair of rotors 13, 13 which holds the carrier between the arranged rotors 13 and holds the carrier, the carrier is moved using the other rotor as a guide, and this is repeated in many rotors. As a result, a large number of carriers 12 are caused to travel along a desired locus, and the yarns 1 held by the carriers 12 are organized into one another,
By changing the moving area of the carrier 12 in the meantime, the three-dimensional woven fabric 2 having a changed cross-sectional shape can be woven. A bobbin or a tension imparting device that imparts a necessary tension to the yarn is attached to the carrier 12.

That is, when weaving a three-dimensional fabric, the three-dimensional fabric being woven is not always required when the carriers of the yarns are made to travel along a predetermined locus by the carrier driving mechanism and the yarns held by the carriers are organized. The desired final woven fabric shape is not always retained, and particularly in the case of a three-dimensional woven fabric having an unequal cross-sectional shape, it is difficult to maintain a desired shape due to strain, deviation, and the like caused by the tension of the yarn. However, according to the woven fabric shape regulating device, the woven fabric shape is regulated by bringing the abutment surface into contact with the woven fabric surface in the vicinity of the cloth fell position, so that the woven three-dimensional woven fabric is held in a substantially final woven fabric shape. It will be possible.
