ABSTRACT:
A method of making a covered article such as an automobile seat cushion is disclosed. The method includes the steps of forming covering members from a covering material which is impervious to a foam material formed by reacting a foamable composition. The covering members are sewed together along sew lines to form a cover. A peripheral edge of the cover is joined to an interior peripheral edge of a locating member. A plurality of small openings are formed along the sew lines of the cover in the sewing operation. These openings are sealed so that the foam material produced upon the foaming of the foamable composition cannot flow therethrough. The cover and attached locating member are positioned in a foaming mold. The locating member aligns the cover properly with respect to the foaming mold so that a vacuum can be drawn on a die surface of the mold to draw a surface of the cover into contact with the die surface. A charge of the foamable composition is placed in an interior volume of the cover and the foaming mold is closed. The foamable composition is reacted to fill the interior volume of the cover with the foam material. The foam mold is opened and the cover is removed therefrom. The locating member is removed from the cover.
