A method and apparatus for forming foam material, such as polyurethane or foam rubber, into any desired shape, including multi-curved objects, e.g. a contoured dress form. A mass of preformed foam material is forced through an opening having a peripheral configuration corresponding to that of the finished article. A die used to force the mass through the opening is of the general contour desired in the end article. After a portion of the original mass is forcibly urged through the opening, such extruded portion is sheared away from the remaining mass in the plane of the opening. After the shearing operation, the cut-away portion of the foam will assume the contours of the die, but in effect be a mirror image thereof.
