  • Method of making an article
    Patent number: 7829003
    Abstract: A mask is used to make an article having two or more layers. The layers are formed from either a paint or polyurethane elastomer composition. The article is made in a mold including a surface defining a mold cavity and having a first and second effect region. For the method, a mask is placed into the mold cavity adjacent the first effect region. Pressure is applied to the mask to retain the mask adjacent the first effect region. A first composition is applied into the mold cavity to form a first layer adjacent the second effect region. The mask is removed from the first effect region. A second composition is applied into the mold cavity to form a second layer adjacent the first effect region. Benefits of pressure applied to a mask are also realized when making the article from a preformed part using the mask outside of a mold.
