    • A sewing apparatus is provided for sewing vehicular air bags. Each air bag includes first and second side panels and a main body panel extending therebetween. First and second sewing machines are provided for sewing the seams between the respective first and second side panels and the main body panel. The sewing apparatus comprises at least one rotatable template to which the air bag side panels are mounted. Rotation of the templates advances peripheral portions of the side panels into proximity to the sewing machine, while longitudinal side edges of the main body panel are simultaneously advanced into the sewing machine. The apparatus includes motors and/or air cylinders for moving the first and second sewing machines and the templates towards or away from one another, and for adjusting the relative elevation of the templates and air bag side panels relative to the sewing machines. The apparatus further includes motors for moving the sewing machines toward or away from one another relative to the templates and for adjusting the rotational orientations of the sewing machines. A controller operatively controls the movements of the templates and sewing machines and the speeds of the sewing machines.
    • 提供一种用于缝制车辆安全气囊的缝纫装置。 每个气囊包括第一和第二侧面板以及在其间延伸的主体面板。 第一和第二缝纫机被设置用于缝合相应的第一和第二侧面板与主体面板之间的接缝。 缝合装置包括安装有气囊侧面板的至少一个可旋转模板。 模板的旋转使侧板的周边部分靠近缝纫机,同时主体面板的纵向侧边缘同时前进到缝纫机中。 该装置包括用于使第一和第二缝纫机和模板彼此移动或移开的马达和/或气缸,并且用于相对于缝纫机调节模板和气囊侧面板的相对高度。 该装置还包括用于使缝纫机相对于模板彼此移动或彼此远离并用于调节缝纫机的旋转取向的马达。 控制器可操作地控制模板和缝纫机的运动以及缝纫机的速度。

    • A device or attachment for a bag filling and weighing machine in which filled bags of pliant material and containing discrete articles are transferred from the filling machine to a bag closing means including sewing head means and wherein a filled bag is moved in upright position with the upper end of the bag secured in a bag holder and then released from the bag holder for movement in upright position to the sewing head means. The transfer device includes a pair of endless chains having inboard lays which extend from the vicinity of the release of the bags from the bag holder to the reengagement of the bag by bag closing means. The endless flexible members include pointed elements which penetrate and engage upper wall portions of the bag above the contents thereof and below the bag holder so as to retain and guide upper wall portions of the pliant bag to the bag closing means. A bag holder having a pointed rod extending therefrom for engagement of excess bag material while the bag is being transferred from the bag holder to the bag closure means.
    • 一种用于袋装和称重机的装置或附件,其中将填充的柔顺材料袋和分散的物品从填充机转移到包括缝合头装置的袋关闭装置,并且其中填充的袋在直立位置上移动, 袋子的一端固定在袋保持器中,然后从袋保持器释放,以直立位置运动到缝纫头装置。 转移装置包括一对环形链,其具有从袋的释放附近延伸到袋保持器到通过袋关闭装置重新接合袋的内侧布置。 无端柔性构件包括穿透和接合袋的上壁部分在其内容物上方并在袋保持器下方的尖锐元件,以便将柔性袋的上壁部分保持并引导到袋关闭装置。 一种袋支架,其具有从其延伸的尖杆,用于在袋从袋保持器转移到袋封闭装置的同时与多余的袋材料接合。
