wall 112 of the female die 110 fig1 is a perspective view which shows the second stage of the process which is to form the ribbons 108 in the horizontal plane before forming the complex contour in workpiece 76c this stage is accomplished by retracting air cylinders 36a and 36d and concurrently extending air cylinders 36b and 36c as shown by the arrows in fig1 as shown in fig1 this retraction and extension of the air cylinders pulls left shaft 22a laterally to the left and forces left shaft 22a against the retaining wall 112 thereby bending shaft 22a against retaining wall 112 at the same time right shaft 22b is being pushed laterally to the left this forces right shaft 22b against workpiece 76c right shaft 22b forces workpiece 76c against shaft 22a and retaining wall 112 this causes workpiece 76c to take on the contour of retaining wall 112 thus this step forms the ribbons 108 of the workpiece 76c in the horizontal plane into the contour of retaining wall 112 we call this step 34 in plane 34 forming of the ribbons fig1 shows the in plane forming of the ribbons 108 in a plan view the next stage of the process is for the complex contour male die not shown to descend against workpiece 76c thereby forcing workpiece 76c down into complex contour female die 110 while carrier sheet 74 supports the bottom surface of workpiece 76c at the same time the male die is.
