Stochastic Local Gauss-Bonnet-Chern Theorem Journal of Theoretical Proba-bility

A system for drawing and ironing can bodies, particularly steel can bodies, characterized by a single stroke press having an equal number of drawing and re-draw stations in combination with a novel means to transfer cups from drawing to re-drawing stations, and a separate ironing press having separate stations to correspond to each re-drawing station. The apparatus for transferring cups across a sheet metal web from blank-draw stations to re-draw stations beyond the edge of the web includes movably mounted first members adjacent the re-draw stations and the surface over which the web passes, extension members connected to the movable first members, gripping members connected to the extension members adjacent the stations, means to move the first members and thus the gripping members across the web and over the edge thereof, and means to actuate the gripping members to grip cups at blank-draw stations and release them at redraw stations.
