Abstract
An improved method for manufacturing a dentifrice containing dispersed speckles therein includes converting a gel or paste dental composition into a plurality of flowing ribbons thereof, directing a stream of speckles onto one such ribbon of dental composition, to which the speckles adhere, bringing together such stream and another stream of such dental compositions so that they adhere together with the deposited speckles sandwiched between them, and controlling relative feed rates of the dental composition and the speckles so that there is produced a dentifrice containing the speckles distributed through it in desired proportion. Also described are apparatuses for carrying out the process.
