Abstract
A process and apparatus for the continuous production of a uniform layer of oose material on a forming belt has a receiving belt onto which the loose product is deposited by a gravity chute in strips transverse to a travel direction of the receiving belt. A smoothing device above the receiving belt engages the strip layer over the entire length thereof on the receiving belt and smooths the material before it passes to a dispersing device directly or via said dispersion belt.

A process for the continuous production of a uniform layer of a loose material, comprising the steps of:
- (a) transforming an incoming loose material into at least one stream of an intermediate product;
- (b) depositing said intermediate product in a layer of strips on a receiving belt transversely with respect to a travel direction of said receiving belt;
- (c) subjecting said layer of strips of said intermediate product on said receiving belt to smoothing action of a combing device working in said travel direction and over an effective length of a combining surface which is at least 7 times greater than a distance between two successive strips;
- (d) setting a distance of said combing surface from said receiving belt at a value which is slightly less than an average height of said layer of strips and which decreases slightly in said travel direction;
- and
- (e) dispersing said material from said receiving belt following discharge from an end thereof onto a forming belt to form said uniform layer of said loose material thereon.

- and
- (e) dispersing said material from said receiving belt following discharge from an end thereof onto a forming belt to form said uniform layer of said loose material thereon,
- said apparatus comprising:
- a feed belt for supplying said loose material;
- another belt forming said receiving belt and located below said feed belt;
- at least one gravity chute above said receiving belt and receiving said loose material from said feed belt and depositing said loose material on said receiving belt;
- means above said receiving belt forming said combing device, said combing device having at least one movable carrier extending in said travel direction and equipped with combing tools, said carriers being height adjustable and having an adjustable angle in the travel direction of the receiving belt;
- a dispersion device receiving said material from said receiving belt;
- and
- a further belt below said dispersion device and constituted as said forming belt.
