Abstract
The description describes a process for forming a composite mat of directionally oriented lignocellulosic material in which elongated small pieces of the material are caused to descend individually as separate and discrete objects through an electric field orienting zone. A horizontal mat-support surface is moved immediately below the orienting zone to receive the descending pieces thereon with the elongated pieces overlapping each other to form a composite mat. An electric current is passed through the mat to produce a directional electric field immediately above the mat in which the electric field is directed in the direction of movement of the mat and parallel with the mat to exert forces on the elongated small pieces to cause the pieces to orient their long dimensions in the direction of the electric field as the pieces descend through the orienting zone in the formation of the composite mat. The electric current is produced within the mat by contacting the mat with electrodes and applying a voltage difference between the electrodes to cause electric current to flow through the mat between the electrodes in the direction of mat travel.
