  • sports balls enclosed in air structures such as soccer, volleyball, and handball generally have an inflatable rubber inner tube, a reinforcing layer, and a skin layer made of leather. According to different manufacturing methods of the skin layer, the sports ball can be further divided into a hand stitching ball and a pasting ball.
  • the hand-sewn sports ball as described above has the advantages of being soft, good to the touch, easy to use, and good in ball control performance.
  • the ball since the ball is three-dimensional, and the leather ball piece reinforced with the backing material is thick (about 4-5 mm) and hard, it cannot be sewn by a sewing machine and can only be sewn by hand. Therefore, there are the following problems: Due to the proficiency in sewing and the difference in skill between different operators, the production efficiency of such sports balls is poor, the price is high, and there are, for example, uneven weights and sizes, and poor roundness. And other quality issues. The failure rate is 2-3 times that of the pasting ball described later, and the durability is poor and the deformation is easy.
  • a sports ball for example, a soccer ball
  • a sports ball receives an internal pressure of about 1.0 kg/cm 2
  • it is subjected to an impact force of 100 kg or more when subjected to a kicking impact. Therefore, problems such as seam cracking may occur, and it may happen that, for example, the ball becomes larger than the standard or deformed.
  • the durability of the hand-sewn ball is 1/2 to 1/3 or less of the pasting ball to be described later.
  • a splicing ball is described in the specification of U.S. Patent No. 4,333,648, which includes: a rubber inner tube identical to the inner tube of the hand-sewn ball described above, which is formed by winding several kilometers of nylon thread in all circumferential directions of the ball.
  • the layer (the structure of the winding wire is referred to as a winding structure), the covering rubber composed of a thin layer of vulcanized rubber coated on the reinforcing layer, and the skin layer composed of a plurality of leather balls bonded to the covering rubber.
  • the covering rubber has a function of firmly bonding the leather sheet to the ball.
  • the reinforcing layer is a winding structure like the pasting ball, the disadvantage of the hard ball and poor ball control of the pasting ball is still not eliminated. And because the lines used are thin and It exists on the surface, so there is a problem that it is cut off by collision with gravel or protrusion. In addition, there is also a problem that the pinhole of the leather ball piece is easily broken. Moreover, since the existence of the sewing thread can be seen between the balls, it gives a feeling of shoddyness.
  • Japanese Patent Publication No. 62-236568 discloses a ball having such a structure: as a reinforcing layer, 12 woven pieces of a substantially trapezoidal shape are sewn around the sewing machine to form a spherical bag layer, but Leaving one edge of the woven fabric sheet without stitching, forming a receiving opening by using the unseamed edge, turning the front and back sides of the cloth bag layer so that the stitched seam head is located inside, and placing the inner tube from the receiving hole into the bag layer Inside. Then, the seam of the accommodating opening is placed on the outer side for sewing. A leather ball is attached to the inner bag of the stitched bag, that is, the inner bag. The compressed air is then filled through a valve (not shown).
  • the reinforcing layer is formed of a woven fabric sheet
  • the touch feeling is good due to the diagonal effect of the cloth, and the ball control performance is also good.
  • the slanting effect means that the woven fabric exhibits a large stretchability when the woven fabric is stretched from a direction which is shifted by a certain angle, for example, 45 degrees with respect to the vertical and horizontal lines. Therefore, the expansion and contraction performance is excellent when subjected to an impact.
