The fall causes all dough pieces to have the same orientation.

Abstract: A web of thermoplastic foam material is carried through an oven by an intermittently traveling conveyor engaging or gripping opposite sides of the web. The heated web is successively advanced by the conveyor between cooled heat-absorbing forming molds, which are moved toward each other to form the foam article and away from each other to release the article. A heat trimmer melts or vaporizes the leading and trailing ends of the foam material as compressed and formed by the molds, to form the marginal leading and trailing ends of the articles to the required peripheral form determined by the leading and trailing ends or edges of the molds and to separate the leading and trailing ends of the article from the web. The cooled molds, which may be made of a heat-conducting metal, such as aluminum, absorb the heat of melting as they pressurize the material along its edges and thereby determine the leading and trailing margins of the article.
