ABSTRACT:
A novel method and means are provided for making constant cross sectional area, pultruded, filament-reinfored articles, such as automotive leaf springs, the shapes of which vary along their lengths. The invention features a specially adapted shaping die for the pultrusion process comprising two pairs of spaced apart die members. The die members and die pairs are mechanically linked so that the spacing between pair members can be changed while the cross sectional area of the die opening remains constant.
