Abstract

To obtain a braider capable of smoothly unwinding yarn without bending the yarn unwound from each bobbin and simultaneously carry out the proper plaiting of a braid without applying an excessive tension to the yarn. This braider is obtained by arranging a mandrel (m) in the interior of nearly a cylindrical track bored on a curved surfacy upper plate (U) on which bobbin carriers (C) are arranged, using a plaiting point (P) on the mandrel (m) as a position where the axial line of a bobbin placed on each bobbin carrier (C) crosses that of the mandrel performing the plaiting of yarn (Y) on the bobbin, smoothly unwinding the yarn (Y) on the bobbin without bending the yarn and feeding the yarn to the plaiting point on the mandrel (m). Since the plaiting point is located on the position where the axial line of the bobbin crosses that of the mandrel, the braider can be miniaturized. Thereby, the operating efficiency of the braider is improved to simultaneously reduce the installation area of the braider.
