ABSTRACT:
The invention is directed to a method and apparatus for gripping DIP components automatically without the need for shutting down the machine to change the tooling assembly when handling components which differ in width. Two sets of fingers are provided, with one set inside the other, such that engagement of the inner pair with a wide component causes automatic retraction of them sufficiently for gripping of the component by the outer pair. In the absence of a component, the inner pair of fingers is automatically extended for subsequent component handling.
