Abstract
Detergent bars (soap or non-soap) are stamped or imprinted using a die or dies having a modulus of elasticity in the range 5.times.10.sup.5 to 1.times.10.sup.7 Nm.sup.-2. This gives reduced adhesion of detergent to die, reduced die-blocking and consequently reduced marring of bars. Preferably each such die has a facing layer of elastomer so as to achieve the desired low modulus of elasticity which preferably is distinctly less than that of the detergent.
Claims8
In an apparatus for stamping a detergent bar comprising means for locating a detergent bar, at least one die member, and drive means for moving said at least one die member relatively towards said bar to stamp said bar,
- the improvement wherein said at least one die member has a total modulus of elasticity within the range 10.sup.5 to 5.times.10.sup.7 Nm.sup.-2.
