ABSTRACT:
A manufacturing framework is used to manufacture a cosmetic puff for a liquid foundation. The cosmetic puff is manufactured by forming a latex film coating on one side of a crimp pattern plate by applying latex film compound thereon. The latex film coated plates are set in the manufacturing framework, and a foamed latex foam compound is injected into the manufacturing framework while coagulant and activator are added therein to thereby produce a gelled latex foam covered with latex films on both sides. The latex foam and the latex films are simultaneously vulcanized to thereby bond the latex films onto the latex foam.
