Abstract
A jointed strand includes a superposed portion in which a first strand end in which fibers are oriented in one direction and a second strand end in which fibers are oriented in one direction are superposed; and a joint portion in which fibers of the first strand and the second strand are interlaced at the superposed portion, wherein the joint portion has a slit extending in a fiber orientation direction and a joint spot adjacent to the slit at one location or a plurality of locations aligned in a direction orthogonal to the fiber orientation direction, and monofilaments of the first strand and the second strand are interlaced at the joint spot.
Claims7
A method of producing a jointed strand comprising:
- providing a superposed portion by superposing a first strand end in which fibers are oriented in one direction and a second strand end in which fibers are oriented in one direction;
- providing a slit extending in a fiber orientation direction at one point or at a plurality of points arranged in a direction orthogonal to the fiber orientation direction by piercing a separation means in the superposed portion, and forming a joint spot adjacent to the slit, wherein the slit and the joint spot are alternately arranged in a direction orthogonal to the fiber orientation direction within the superposed portion;
- and
- jointing the first strand and the second strand at the joint spot by interlacing monofilaments to form a joint portion including the slit and the joint spot.
