ABSTRACT:
A method and apparatus are described for cutting the web remaining from a plastic sheet containing thermoformed articles into strips, loosely indexing and aligning a plurality of thermoformed articles in each strip with article punches, sequentially isolating the articles from each other so that they have complete freedom of movement in both across-machine and machine directions, exactly registering the articles with the article punches in a selected sequence, precisely trimming the articles from the plastic web, and ejecting them from the apparatus.
