Abstract:

A method for making hardwood or decorative plywood. The plywood includes a number plies including a back veneer, a face veneer, and a number of core and center plies. The method forms subunits of plies and stacks the discrete formed subunits to form a unit. The unit is processed to forms discrete hardwood panels. Subunits having different sets of plies are formed. The subunits are formed by sequencing the order of placement of the plies so that the face and back veneers do not touch the conveyor. This process enables line assembly of hardwood plywood. Without this sequencing, at least the back veneers would touch the conveyor subjecting the panel to aesthetic damage due to the nature of the outer veneers. This process also significantly reduced the labor necessary for forming the panels because numerous subunits can be formed simultaneously.
