Abstract: In a process and apparatus for the fibers of composite building panels, bars are laid against a rotating drum, parallel to each other and close together. Parallel threads or wires which extend in the direction of the drum periphery are then would around the outside of the bars, in a stressed condition, whereby the bars being transported by the drum are pressed against the peripheral surface thereof. The bars are connected by a hardenable binding agent to fibres and a thin sheet of suitable material which move with the drum, and the binding agent is caused to harden, thereby forming a first strip on the drum. The first strip is then brought into a condition of extending parallel to a second strip produced in the same manner, with an adhesive between the two strips. The two strips are then passed through a pair of rollers which press the assembly together, thereby forming an elongate panel configuration.
