Apparatus for transferring articles (such as two-piece cans) between work stations, at succeeding ones of which a dimension (such as a diameter) of the articles is reduced. The articles pass along a channel, and at each station means are provided to stop the articles in position to be operated upon. After the completion of an operation which reduces the dimension of the article, the article may pass the stop means, and be transported to the next station, where other stop means are provided to position the article for the next operation. The articles are conveyed along the channel by aerodynamic or other means. Each of the stop means is shaped to fit the article which is stopped by it, and vacuum means are associated with the stop means to insure accurate positioning of the articles at each station for the operation to be performed on them at that station.
In an apparatus for manufacturing articles, such as two-piece can bodies, wherein a series of operations are performed on said articles at a first station, at least one intermediate station and a final station, a dimension of said article being reduced at said intermediate station;
In an apparatus for manufacturing two-piece can bodies and the like, wherein a circular blank is cut from a strip of metal and drawn into a cup at a first station, said cup is redrawn and its diameter reduced at a second station, and is then again redrawn and its diameter is further reduced at a third station, and is trimmed at a fourth station, said first station and intermediate stations each having a cooperating plunger and die, and means for positioning the cup on a pass line after the respective operation;
