Abstract
An apparatus and related methods for touchlessly holding down overlay paper on a lignocellulosic composite mat as the mat and overlay are loaded into a multi-level press from a matching multi-level loader cage. In several exemplary embodiments, each level of the loader cage has a pressured air plenum, pipe, or tube, with a uniform continuous opening (gap, slit) extending linearly from which pressurized air exits. Depending on the configuration, the pressured air exits in a focused, laminar flow pattern.
Claims5
A method for loading a lignocellulosic composite mat with an overlay into a press, comprising:
- placing a paper overlay on a top surface of a lignocellulosic composite mat on an infeed conveyor;
- inserting the lignocellulosic composite mat and paper overlay into a holder in a loader cage;
- moving the lignocellulosic composite mat and paper overlay from the loader cage through an exit opening into a corresponding opening in a press;
- and
- applying pressurized air at an angle to the lignocellulosic composite mat and paper overlay as they move from the loader cage through the exit opening.
