    • A system for handling axial lead components comprises a flexible metal tape or molded plastic strip (to electrically test components while on strip), that has been especially perforated by die punching to have a plurality of sprocket receiving holes along its edges and a plurality of component receiving holes spaced centrally and along the length of the tape. The component holes have tabs at each lateral end thereof that define a component lead receiving slot. The slot has a predefined width at the end away from the tape. The slot width increases toward the base of the tabs. The predefined width of the slot at the end away from the tape is smaller than the diameter of the lead to be received in the slot. Only by flexing the tape to spread the tabs can a lead be inserted, freely rotated or removed from the slot. At least one tape flexing station is associated with each system. The tape flexing station comprises a cylindrical surface of sufficiently small radius of curvature at one position such that the tape pulled over the surface will be sufficiently flexed to spread the tabs to open the slots enabling a lead to be moved therein. Associated with every flexing station is at least one driving hold down that pulls the tape over the cylindrical surface and advances the tape by engaging the sprocket receiving holes.
    • 用于处理轴向引线部件的系统包括柔性金属带或模制塑料条(用于在条带上电测试部件),其特别是通过冲模穿孔以沿着其边缘具有多个链轮容纳孔,以及多个部件 接收沿中心并沿着带长度的孔。 部件孔在其每个侧端具有限定部件引线接收槽的突片。 狭槽在距离磁带的一端有一个预定的宽度。 槽宽度朝向突出部的底部增加。 远离磁带的端部的槽的预定宽度小于在槽中要接收的导线的直径。 只有通过弯曲磁带以扩展凸片,可以将引线插入,自由地旋转或从槽中移除。 至少一个磁带弯曲台与每个系统相关联。 带弯曲台包括在一个位置处具有足够小的曲率半径的圆柱形表面,使得拉过表面的带将被充分弯曲以扩展突片以打开狭槽,使得引线能够在其中移动。 与每个弯曲站相关联的是至少一个驱动压紧装置,其将带材拉到圆柱形表面上,并且通过接合链轮接收孔使胶带前进。
