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.
Claims17
A device for stamping a substrate comprising a die, the die having at least one substrate stamping surface having an elastomeric coating, said die including an edge positioned to extend inwardly over a leading edge of the elastomeric coating for delaying tearing of the elastomeric coating from the surface of the die.
A device for stamping a substrate comprising a die, the die having at least one substrate stamping surface having an elastomeric coating, said die including an edge positioned to extend inwardly over a leading, exposed edge of the elastomeric coating for delaying tearing of the elastomeric coating from the surface of the die.
A device for stamping a substrate comprising a die, the die having at least one substrate stamping surface having an elastomeric coating having a generally vertically ascending section, said die including an edge positioned to extend inwardly over a leading edge of said vertically ascending section of the elastomeric coating for delaying tearing of the elastomeric coating from the surface of the die.
A device for stamping a substrate, comprising a die, the die having a detergent bar cavity including a bottom wall and a side wall, said die including an edge extending inwardly over said side wall, said bar cavity comprising a substrate stamping surface having an elastomeric coating, said edge being positioned to extend inwardly over a leading edge of a section of the elastomeric coating for delaying tearing of the elastomeric coating from the surface of the die.
