Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a braider for forming various braids by assembling a plurality of yarns or fiber bundles (hereinafter simply referred to as "yarns").

[0002]

2. Description of the Related Art Heretofore, there has been known a braider which forms a braid by interlacing yarns or fiber bundles around mandrels of various shapes.

[0003]

Conventionally, there has been known a braider which automatically composes braids around a mandrel having a two-dimensional structure such as T-shape or I-shape or a mandrel having a three-dimensional structure such as tetrapot. In addition, after the braid composition, it was considered to automate the process of cutting the yarn group connected between the braid and the yarn pulled out from the bobbin placed on the bobbin carrier and heading to the composition point. The braider is unknown.

Conventionally, braids having a two-dimensional structure or a three-dimensional structure are made by hand. Therefore, the braids thus formed are very expensive and are not used in large quantities in many industrial fields. It was almost impossible. Further, the yarn group connected between the braid and the yarn drawn from the bobbin placed on the bobbin carrier and heading to the composition point is also manually cut, and a considerable skill is required to cut the yarn group. And it takes time. In particular, in a large braider, the cutting position of the yarn group is high, and the bundle of yarn groups to be cut is thick, so it is extremely difficult to cut by hand, and dangerous work is required. It is accompanied.

The object of the present invention is to draw a mandrel control device capable of gripping and controlling the position of a mandrel having a one-dimensional structure, a two-dimensional structure or a three-dimensional structure or a braid and a composition point drawn from a bobbin mounted on a bobbin carrier. It is an object of the present invention to provide a braider in which a cutting device and the like for cutting a yarn group continuous with a yarn heading toward the head are arranged so that the braider can be automated and maintenance and inspection work is easy.

[0006]

In order to achieve the above object, the present invention provides a mandrel for cutting and supporting a mandrel and a cutting device for cutting a yarn group connected to a braid in order from the front of a braider body. A mandrel device equipped with a control device is provided.
