    • A winding machine for manufacturing transformer cores includes a ribbon-dispensing assembly which travels in a predetermined path about a stationary mandrel to deposit successive layers of ribbon upon the mandrel under controlled tension while applying transverse pressure to the peripheral surface of the winding to press air from between the layers. In the preferred embodiment, a counterbalanced rotating track engages the ribbon-dispensing assembly as it travels around the mandrel. The ribbon dispensing assembly is preferably transported by a chain drive.
    • 用于制造变压器铁芯的绕线机包括:带状分配组件,其在预定的路径中围绕固定的心轴行进,以在受控的张力下将连续的带状层沉积在心轴上,同时向绕组的周边表面施加横向压力以将 层之间。 在优选实施例中,当色带分配组件围绕心轴行进时,平衡旋转轨道与色带分配组件接合。 色带分配组件优选地通过链传动来传送。

    • A machine for forming a core of laminations from a strip of material includes a forming section for forming the strip into a generally rectangular configuration and severing the formed section from the strip. A first gripper advances the strip to the forming station for formation of a first pair of sides of the lamination and a second gripper advances the strip to the forming station for formation of a second pair of sides of the lamination. A first stop interrupts the strip advancing motion of the first gripper and a second stop interrupts the strip advancing motion of the second gripper. An auxiliary stop cooperates with the first gripper for providing strip advancing motion of the first gripper less than that allowed by the first stop so that one of the first pair of lamination sides is provided with two discontinuous portions. An extractor removes a formed lamination from the forming station and a separator opens formed lamination at its discontinuity. An inserter thereafter inserts the formed lamination about a preformed coil of electrical conductor and recloser engages the lamination to reclose it after the insertion.
    • 用于从材料条形成叠片的芯的机器包括:形成部分,用于将条形成为大致矩形的构造,并将形成的部分与条切断。 第一夹持器将条移动到成形站,以形成层压体的第一对侧面,并且第二夹持器将条带前进到成形站,以形成层压体的第二对侧面。 第一停止中断第一夹持器的条带前进运动,并且第二停止中断第二夹持器的条带前进运动。 辅助停止件与第一夹具配合,用于提供第一夹持器的条带前进运动小于第一挡块允许的前进运动,使得第一对层叠侧中的一个设置有两个不连续部分。 提取器从成形台移除成形的层压,并且分离器在其不连续处打开形成的层压。 插入器此后将形成的叠片插入预先形成的电导体线圈上,重合器接合层压,以在插入之后将其重新闭合。
