ABSTRACT:
The disclosed apparatus defines a soap press component and a grinding component, operatively associated with one another. The grinding component has an inlet for receiving small soap bars or end pieces, and means for grinding them up to even finer pieces or shavings. The soap press component has wall structure defining a chamber having open top and bottom ends; a removable bottom wall is used to close the open bottom end, and a movable upper shaping form is used to close the open top end. A rotatable screw connected to the upper shaping form provides for moving such form from an elevated position spaced above the open top chamber end, to a lowered position extended into and through the chamber. The grinding component outlet discharges the soap pieces or shavings to above the open top chamber end; whereby they drop then into the chamber from the open top end thereof. Rotation of the screw moves the upper mold plate axially into the chamber and against such soap shavings, to pressure form them into a single bar shaped the same as the chamber. The shaped bar is removed from the chamber bottom end, upon opening the bottom wall, by shifting it to an opened position laterally offset from the open bottom end of the chamber.
