Abstract
An apparatus permitting formation of a flanged product with the wider flanged portion in engagement with a foraminous transporting device. The apparatus uses a mold-like former having a narrower or smaller portion separated from the foraminous surface by a wider flange forming portion. The flange forming portion is adjacent to the foraminous surface and is separated from the foraminous surface after pad formation leaving the formed pad behind.
Claims10
In an apparatus for forming a complexly shaped product, the apparatus having at least one fiber supply means to supply opened fibers to an air stream which air stream entrains and transports said fibers to a condensing surface, the improvement comprising:
- (a) a moving foraminous surface forming said condensing surface positioned to pass through said air stream substantially transversely thereto;
- (b) a continuous molding loop defining at least one mold, for receiving entrained fibers from said air stream which are condensed on said foraminous surface within said mold to form a product having a shape defined in part by said mold and said foraminous surface, said mold comprising:
- (i) a first mold portion adjacent said foraminous surface defining an opening of predetermined shape and dimensions;
- and
- (ii) a second mold portion separated from said foraminous surface by at least said first mold portion and defining an opening of predetermined shape and dimensions which blocks a part of the opening defined by said first mold portion;
- and
- (c) means for moving said molding loop along a path which passes in part adjacent to and in the same direction of movement as said foraminous surface and in part away from said foraminous surface leaving products formed in said mold deposited on said foraminous surface.
