Addressed is the object of improving an unwinding performance of a glass direct roving at an end surface. A method of manufacturing a glass direct roving includes winding a glass strand into a cylindrical shape while traversing the glass strand. In the winding, the glass strand is wound traversing the glass strand under the conditions that a wind order of the crosswindng is or greater, and an interval parameter, which is the smaller value among “b” and “A−b”, is from “(A/2)*−(A/4)*” to “(A/2)*−1”, where “A” is the wind order, “(A/2)*” is a maximum integer no greater than ½ the wind order, “(A/4)*” is a maximum integer no greater than ¼ the wind order, and a mixed fraction “a+(b/A)” is used to express a cyclewind of the crosswindng.

A method of winding fibre to create a tubular winding by using at least three different motions to create interlocking segments. The interlocking segments may have at least one fibre parameter that is different, such as colour. The tubular winding may be bent into a curved shape so that a portion of each of the segments is visible.

Provided is a wound body of a commingled yarn, the wound body being capable of effectively suppressing fraying and sagging, disorder of a lower layer, or breakage of the commingled yarn during winding or use. Also provided is a method for manufacturing the wound body. The wound body contains a core member and a commingled yarn traversely wound onto the core member; wherein the commingled yarn is traversely wound onto the core member in two or more directions; and when the wound body is placed on a white substrate in a light-shielded space such that a cylindrical direction of the core member is upright, and light is irradiated toward a plane that includes a center axis of the cylinder, from a point that is moved a distance of a radius of the core member plus 180 cm in a direction perpendicular to the center axis from an intersection point between the center axis of the core member and the white substrate on a surface of the white substrate, and is further moved 210 cm in a direction perpendicular to the substrate face of the white substrate, linear reflection lines of a quantity equivalent to the number of directions of the traverse winding are formed on a surface of the traversely wound commingled yarn.

A reeling device includes: a left spool body; a right spool body; and a yarn transfer mechanism. A first rotation axis of the left spool body and a second rotation axis of the right spool body are parallel to each other, and a position of the left spool body around which the yarn-shaped body is to be wound and a position of the right spool body around which the yarn-shaped body is to be wound are arranged side by side on a first imaginary plane orthogonal to the first rotation axis and the second rotation axis. After a hollow yarn collection is formed in the left spool body, a yarn-shaped body leading portion of the yarn transfer mechanism moves the yarn-shaped body from the left spool body to the right spool body along the first imaginary plane.
