Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1 . 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. 2 . The method according to claim 1 , wherein a gas is ejected to interlace the monofilaments of the first strand and the second strand. 3 . The method according to claim 1 , wherein at least one strand of the first strand and the second strand is a strand subjected to a partial separation treatment. 4 . The method according to claim 2 , wherein at least one strand of the first strand and the second strand is a strand subjected to a partial separation treatment. 5 . A method of producing a jointed strand comprising: providing 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; forming a joint portion by interlacing monofilaments of the first strand and the second strand in the superposed portion; and providing a slit extending in a fiber orientation direction and forming a joint spot adjacent to the slit by piercing a separation means in the joint portion, at one location or a plurality of locations arranged in a direction orthogonal to the fiber orientation direction, wherein the slit and the joint spot are alternately arranged in a direction orthogonal to the fiber orientation direction within the superposed portion. 6 . The method according to claim 5 , wherein a gas is ejected to interlace the monofilaments of the first strand and the second strand. 7 . The method according to claim 5 , wherein at least one strand of the first strand and the second strand is a strand subjected to a partial separation treatment.
