摘要： Provided is a method for manufacturing an exercise ball which is made by using a pasted ball such as a soft leather ball and which has a lower impact value compared to a conventional yarn-wound ball. The exercise ball comprises a spherical hollow rubber bladder (2) in which compressed air is sealed, and a yarn-wound reinforcement layer (3) formed by evenly winding a filament yarn around the surface of the rubber bladder, wherein the exercise ball is characterized in that nylon filament yarn, obtained by hard twisting two 30-50 denier nylon filaments 1-a, 1-b in a single-direction twist is used as a winding yarn (1).

摘要： There is provided a sports ball capable of relieving the pain of the hands suffered from impact on the ball and having a soft feel and high flexibility. The sports ball comprises a spherical hollow rubber bladder (2) inflated with air injected into it, a fabric tape reinforcement layer (3) formed by winding a narrow adhesive-impregnated fabric tape (7) around a central spherical portion (6) of the rubber bladder about each of three axes of the rubber bladder with the exception of opposite spherical end portions (5) of the rubber bladder, whereby the fabric tape reinforcement layer is formed as orthogonal lap windings of the fabric tape over substantially all of the spherical surface of the rubber bladder, to provide a fabric tape wound ball core, and surface panels (4) adhered with adhesive to the fabric tape reinforcement layer on the rubber bladder, after vulcanization and forming of the fabric tape wound ball core.

摘要： A method of forming a strong seam by using a sewing machine, without backstitching. In the sewing machine, a first shuttle hook which rotates in the counterclockwise direction, a first needle, a second needle, and a second shuttle hook which rotates in the counterclockwise direction are arranged in turn in the feed direction. A material to be sewn is fed every time when the needles simultaneously and independently form stitches, so as to form two independent seams which overlap each other in a manner such that the knots of the seams overlap each other on each knotted point, where one of the seams consists of perfect stitches, and the other seam consists of hitch stitches.

摘要： Surface panels of a sports ball are arranged to facilitate bending of their outer peripheral edge portions into an arc, without reducing strength of an elastic member, to define a groove at a seam between adjacent panels. Panels are adhered through the elastic members to a body defining a ball core with high adhesion strength. The panels have sheet material backed by an elastic member, each panel having an arched portion formed by bending inwardly an outer peripheral edge portion of each panel with a radius of curvature more than the thickness of the panel, after formation of many apertures in an inner peripheral edge portion of the elastic member. Lower edges of the arched portions of adjacent panels abut each other. A groove is defined at seams between adjacent panels, and the panels are adhered to a ball core body by adhering the elastic members to the body.
