Abstract
A mat-forming apparatus, especially for the production of particle board, comprises a conveyor grate disposed above a layer-carrying surface, e.g. a conveyor, and below a feeder for scattering the particles onto the surface through the travelling grate. According to the invention, the lower pass of the conveyor grate is displaceable in the same direction as the receiving conveyor and is inclined upwardly away from the receiving conveyor in the direction of displacement thereof at an acute angle, this lower pass forming an inclined plane.
Claims6
An apparatus for forming a layer of transversely oriented particles, especially for the production of particle board, said apparatus comprising:
- a continuously movable layer-receiving surface;
- a pair of roller members spaced apart along said surface in the direction of movement thereof;
- an endless traveling grate disposed above said surface and looped around said roller members said traveling grate having a lower pass moving generally in the direction of movement of said surface, said traveling grate having flights extending transverse to the direction of movement of said surface and adapted to orient particles deposited thereon, said flights being spaced apart in said direction whereby particles can fall through the passes of said grate between said roller members, said flights having lower edges which define an inclined plane path along a lower pass of said traveling grate diverging from said surface in the direction of movement of said lower pass;
- and
- a dispenser for said particles disposed above said traveling grate and substantially extending over the length thereof for depositing particles on said surface through the upper and lower passes of said traveling grate between said roller members.
