Abstract

An automatic winding device for a filamentous material which is an automatic winding device for a filamentous material that winds a plurality of provided filamentous materials simultaneously onto a plurality of bobbins; and an automatic winding method utilizing the automatic winding device are provided. The automatic winding device includes a plurality of spindles for winding bobbins and a guide roll. The number of the plurality of spindles is 1-1.75 times the number of thread handling routes.

Claims (8)

1. An automatic winding device for a filamentous material, which simultaneously winds a plurality of supplied filamentous materials onto a plurality of bobbins, the automatic winding device comprising:

a plurality of spindles for installing the bobbins; and

a plurality of guide rolls, wherein each of the plurality of supplied filamentous materials is guided over at least one of the plurality of guide rolls to a respective one of the plurality of spindles, and

a plurality of drive rolls, wherein each of the plurality of drive rolls is independently driven, supplies each of the filamentous material simultaneously and adjusts a winding speed of each of the filamentous materials individually,

wherein a number of the plurality of spindles is more than 1 and less than 1.75 times the number of the plurality of supplied filamentous materials, and each of the plurality of spindles is respectively disposed at each of positions of vertexes of at least one regular polygon or at least one rhombus.

2. The automatic winding device according to claim 1 , wherein a plurality of intervals disposed between the spindles is 1.2-3.0 times a diameter of the bobbins.

3. The automatic winding device according to claim 1 , wherein the plurality of spindles is arranged linearly to form one or two rows or more; and

among the plurality of spindles, at least the spindles in a same row are spaced by equal intervals.
