ABSTRACT:
TECHNICAL FIELD
The present invention relates to a braid and a braiding machine, and more particularly, to a polygonal braid and a braiding machine therefor, in which a guide plate having a track capable of braiding a polygonal braid and a feed gear corresponding thereto are provided. The polygonal braid braided in a square or triangular shape can be utilized as a binding string for shoes or clothes etc because of increased binding force by a polygonal. Braids of various quality and colors may be created by using different qualities or colors of strands.
BACKGROUND ART
Braids are utilized in several fields, for example, as part of an electric wire or hose, as a binding string etc. A specific braid is formed on the outer circumference of the electric wire or the string and provides an elastic and relaxed covering for an interior electrc wire or a string etc. and protects the interior electric wire from being contaminated or damaged by impact, braids are often used in place of string for daily use in shoes or clothes etc., in addition to specialized uses.
A general braider is composed of a guide plate having a track on which a spool is moved, a feed gear for moving an electric spool along the track the guide plate, a driving gear for driving a plurality of feed gears and a plural number of rollers on which a braided wire is wound, etc.

Therefore, a plural number of spools of yarn are rotated, repeatedly performing a rotation and a revolution centering around a center point of the guide plate

On an outer circumference of the central yarn, thus, a braid based on a cylindric shape is produced by the rotation of the spool as shown in

DISCLOSURE OF INVENTION
The ordinary cylindrical braid as described above, when used as a binding of shoes, has a low frictional force due to the cylindrical shape which can result in the shoe lace coming loose.
Whan a braid is made using a single color, by prior art methods, the brain color is monotonous; when using a single color, by prior art methods, the braid color is monotonous; when using various colored braid, the braid color may appear untidy.
In order to overcome the problems presented in prior art braiding methods, the present invention teaches a braid formed in a polygonal shape such as a triangle or a square shape with each edge of each face the polygon intersecting with an edge of the adjoining face of the polygon.
