An apparatus is disclosed for use in continuously and automatically forming a highly polished and lustrous surface on the exterior of an advancing billet of plastic material, such as soap, which emerges from the nozzle of an extrusion apparatus. The apparatus includes an enclosed reservoir containing a lubricating fluid that is compatible with the soap, so as to ensure a polished surface on the exterior surface of the soap. The apparatus embodies outlet means having a continuously smooth and generally tapered wall surface that defines an outlet opening for the cavity and is dimensioned and configured to be less than the cross-sectional dimension of the emerging soap by a predetermined amount so as to contact substantially the entire peripheral surface of the soap. In this manner, the wall surface gently wipes the fluid from the advancing billet surface and continuously presses its exterior surface so as to reduce the cross-sectional dimension by a predetermined amount which forms the highly polished and lustrous billet surface.
