To cut panel edges or ends at an angle to make smooth mating joints between panels. Light lumber strips nailed between major framing members to support edges of structural panels where they meet. A localized delamination caused by steam pressure buildup during the hot pressing operation. The steam may result from high moisture content of the veneer, excessive glue spread, or high press temperatures. Pressure is applied to keep mating parts in proper alignment.
Most glues used in panel manufactures require both heat and pressure to cure properly.
See also CUP . A beam built of lumber and plywood in the form of along hollow box which will support more load across and opening than will its individual members alone. Short wood or metal braces or struts placed crosswise between joists to help keep them in alignment. Bridging may be solid or crossed struts.
