Abstract
A vacuum holder for articles, a combination of a vacuum holder and an article, a system for holding and conveying articles, and a method for holding and conveying articles are disclosed. The vacuum holder includes a main body having a surface and an air passageway leading to the surface, and a valve joined to the main body and in fluid communication with the air passageway. The vacuum holder includes an extensible skirt gasket with an opening therein. An article can be placed adjacent to the surface of the main body, and a vacuum can be drawn through the air passageway to hold the article to the vacuum holder. The valve maintains the vacuum between the article and the vacuum holder without being connected to a vacuum source, until it is desired to release the article from the vacuum holder.
