Description

Description: TECHNICAL FIELD The present invention relates to a method for supplying a weft rod for inserting between a plurality of parallel warp rods arranged in parallel in a rod type three-dimensional loom. It is a thing.

[Prior Art] A rod type three-dimensional loom is shown in the drawing of Japanese Patent Application No. 63-245759 previously proposed by the present inventors. In this three-dimensional loom, a weft rod to be inserted between a large number of parallel warp rods is fed from a long rod material while being cut into a required length.

In such a method, not only it is necessary to consider the matching of cutting of the rod and insertion between the longitudinal rods, but also if the interval between the longitudinal rods is not sufficiently large, the rods to be inserted will not be able to be inserted. There is a problem that the tip is caught on the longitudinal rod. However, if the interval between the warp rods is increased, it is necessary to beat the rods in the insertion direction of each rod after weaving, and the rod length corresponding to the rod interval narrowed by the beat is wasted.

In order to avoid such a problem, it is conceivable to sharpen the tip of each rod to be inserted, but it is extremely difficult and troublesome to perform such processing on the tip of each rod.

[Problems to be Solved by the Invention] A technical object of the present invention is to provide a three-dimensional loom of a rod type with a predetermined length of a weft direction rod to be inserted between a plurality of parallel warp direction rods arranged in parallel. Another object of the present invention is to obtain a weft direction rod supply method which is prepared by cutting into a longitudinal direction rod and which is capable of preventing the tip of the tip from being caught by the longitudinal direction rod by a simple means at the time of insertion between the longitudinal direction rods.

[Means for Solving the Problems] The weft direction rod supply method of the present invention for solving the above problems comprises: arranging a number of rod materials for weaving a three-dimensional fabric in parallel on one plane. A cutting step of cutting those rod materials into a rod array by cutting the rod material into a length required for a three-dimensional fabric, a chamfering step of chamfering corners on both front and back sides at a cut end of the rod array, the chamfering The setting step of placing the chamfered rod array body in the groove of the magazine while keeping the arrayed state, and the parallel direction of the rods in the groove of the magazine is parallel to the longitudinal direction rod in the rod type three-dimensional loom. Direction, and with the chamfered rod tip facing the longitudinal rod side, mount the magazine on the rod type three-dimensional loom, and Rod insertion step of inserting between sequentially extruded direction rod through it a rod from one end of the groove kick, is characterized in that it comprises a.

[Operation] A large number of rod materials are arranged in parallel on one plane and cut into a required length, and a rod array body with chamfered corners on both the front and back sides at the cut end of the rod is used in the magazine as it is. Place this magazine in the groove, orient the rods in the groove in the direction parallel to the longitudinal rods in the rod type three-dimensional loom, and point the chamfered rods toward the longitudinal rods. When mounted on a three-dimensional loom, both corners of the tips of the rods inserted between the longitudinal rods facing the longitudinal rods are chamfered so that they can be easily inserted between the longitudinal rods.

Therefore, when the rods are sequentially pushed out from one end of the groove in the magazine and are inserted between the longitudinal rods, the rods can be easily inserted without being caught by the longitudinal rods. Moreover, such easy insertion of the rod can be realized by a simple means of chamfering the corners of the cut end of the cut rod on both the front and back sides, and storing the rod in the groove of the magazine in the arrayed state. .

[Example] In the present invention, a rod material used for producing a three-dimensional woven fabric is one in which a large number of fibers are preliminarily oriented in the same direction and are combined into a matrix to form a rod. To do.
