Abstract: Modular die or mold assemblies comprise a platform, and at least one die or mold unit which is releaseably connected to the platform. The invention permits rapid changing of molds or dies, especially in the manufacture of detergent bars, such as soap bars. Surface ornamentation such as logos can be imparted to the detergent bars either directly from the stamping surface of the dies, from the stamping surface of the dies through an elastomeric lining, or from the surface of the elastomeric lining; in the latter case the indicia is imparted by a mold used to prepare the lining. The modular molds may be used where it is desired to coat the dies with elastomer, particularly where logos are imparted to the elastomeric layer, and where it may be desirable to change the logos, e.g., by changing the modular mold units.

Abstract: A device for stamping a detergent bar, i.e. a bar comprising soap, a synthetic detergent active or a mixture thereof, includes a die. The die has at least one bar stamping surface provided with at least one elastomeric coating which includes a conductive filler such as stainless steel powder. Good release of the detergent bars from the die is possible particularly when the dies are chilled. Use of the conductive filler facilitates chilling of the dies.

Abstract: A device for stamping a detergent bar, i.e. a bar comprising soap, a synthetic detergent active or a mixture thereof, includes a die. The die has at least one bar stamping surface provided with at least one elastomeric coating and includes an edge for delaying tearing of the elastomeric coating. Good release of the detergent bars from the die is possible without chilling of the dies. Use of the edge increases the useful life of the coating.

Abstract: A device for stamping a detergent bar, i.e. a bar comprising soap, a synthetic detergent active or a mixture thereof, includes a die half and a release fluid reservoir. The die is porous so that at least one bar stamping surface has pores through which a release fluid may be to facilitate clean release of the detergent bar cleanly after stamping. Good release of the detergent bars from the die is expected without or with reduced chilling of the dies.
