    • A method and apparatus for sewing cover halves together around a baseball core or the like. The method includes the steps of advancing first and second needles in one direction over an edge of a first cover half and under and through an edge of an adjacent second cover half. The needles carry first and second double threads through the second cover half. The ball cover is then indexed forward and the first and second needles are advanced in an opposite direction over the edge of the second cover half and under and through the edge of the first cover half for carrying the first and second threads over the edge of the second cover half and through the edge of the first. Prior to the second step of advancing, the second thread is positioned between the first and second needles and above the first needle so that a regular herringbone stitch pattern between the first and second cover halves is achieved as the steps are sequentially repeated. The apparatus includes first and second needles and means for shuttling the needles in parallel, and abreast, back and forth over and under and through opposing cover halves. During every other shuttle motion a tab holds the second thread between the needles and raised the thread above the first needle so as to create a regular herringbone stitch pattern between the first and second cover halves.
    • 一种围绕棒球芯等将盖半部缝合的方法和装置。 该方法包括以下步骤:使第一和第二针在一个方向上延伸超过第一盖半部的边缘并且在相邻的第二盖半部的边缘下方并穿过相邻的第二盖半部的边缘。 针将第一和第二双线穿过第二盖半部。 球罩然后向前索引,并且第一和第二针在第二盖半部的边缘上相反的方向前进,并且在第一盖半部的边缘下方并穿过第一盖半部的边缘,以将第一和第二螺纹承载在 第二个盖半和通过边缘的第一。 在进行第二步之前,第二线被定位在第一针和第二针之间并且在第一针之上,使得在顺序重复该步骤之后,实现第一和第二盖半部之间的规则人字形针迹图案。 该装置包括第一和第二针和用于平行地穿梭针的装置,并且在相对的两个半部上并且穿过相对的两个半部并排并排。 在每隔一个穿梭运动期间,翼片保持针之间的第二线,并使线在第一针上方升高,以便在第一和第二盖半部之间形成规则的人字形缝合图案。

    • A method is provided for hand stitching a multi-panel sports ball. The method includes moving the free ends of opposed gripping arms of a panel gripping assembly into an open position; positioning a pair of panels to be stitched to form a multi-panel sports ball between the free ends, with edges of the panels and holes formed along the edges being in position for stitching; allowing the free ends to move from the open position to a closed position; forming a first stitch in the panels by passing a stitching fiber through a first set of aligned holes in the panels; engaging opposite ends of the stitching fiber in first and second gripping members disposed at opposite sides of said gripping arms; tightening the first stitch by actuating a pneumatic cylinder associated with the first and second gripping members to move the first and second gripping members relatively apart; removing the opposite ends of the stitching fiber from the first and second gripping members; and, repeating the stitch-forming and stitch-tightening steps to form subsequent stitches, until stitching along the edge is completed.
    • 提供了用于手工拼接多面板运动球的方法。 该方法包括将面板夹持组件的相对的夹持臂的自由端移动到打开位置; 定位要缝合的一对面板,以在自由端之间形成多面板运动球,其中沿着边缘形成的面板和孔的边缘处于用于缝合的位置; 允许自由端从打开位置移动到关闭位置; 通过使缝合纤维穿过所述面板中的第一组对齐的孔而在所述面板中形成第一线迹; 将所述缝合纤维的相对端接合在设置在所述夹持臂的相对侧的第一和第二夹持构件中; 通过致动与第一和第二夹持构件相关联的气动缸来紧固第一线圈以使第一和第二夹持构件相对分开; 从所述第一和第二夹持构件移除所述缝合纤维的相对端; 并且重复进行线圈形成和线圈紧固步骤以形成后续的线圈,直到完成沿着边缘的缝合。
