Abstract
Apparatuses and methods for forming a joggle and a longitudinal ridge in a multi-ply composite charge are disclosed. Charges may be formed in a forming press that comprises a joggled die, with a longitudinal ridge and a joggle that crosses the longitudinal ridge, and a conforming die, with a series of longitudinally-spaced die fingers. The die fingers include pairs of die members configured to move laterally between a closed position and an open position, with each die member configured to tilt longitudinally.
