Abstract

Abstract A system for efficiently utilizing a wood veneer peeling lathe and dryer by installing a number of horizontally disposed and vertically spaced veneer storage and conveying trays spanning from the peeling lathe to the dryer. More levels of trays are provided than levels of conveyors in the dryer to insure a ready source of veneer to keep the dryer supplied with no gaps between pieces of veneer. A waste removal clipper may be positioned between the ends of the trays for removal of defective portions of veneer. The wetter portions of veneer can be conveyed to a slower dryer conveyor while the drier portions can be conveyed on a faster dryer conveyor without overdrying.

Claim 2
Dependent Claim 74 words
A process of producing veneer comprising the following steps: a. peeling logs in a peeling means to produce veneer; b. conveying said veneer from said peeling means in sequence to more than one level of storage tray means; c. conveying said veneer in sequence from more than one level of said storage tray means in a continuous edge-to-edge supply directly to one level of a dryer; and d. drying said veneer in said dryer.
Claim 3
Dependent Claim 125 words
A process of producing veneer comprising the following steps: a. peeling logs in a peeling means to produce veneer; b. conveying said veneer from said peeling means to storage tray means; c. conveying said veneer from said storage tray means in a continuous edge-to-edge supply directly to a dryer; and d. drying said veneer in said dryer, wherein; said dryer has at least two levels of conveyors transmitting its length, the veneer peeled from the sap portion of the logs is conveyed to one set of said storage trays to supply one level of said dryer, and the veneer peeled from the heart portion of the logs is conveyed to a second set of said storage trays to supply a second level of said dryer.
Claim 4
Dependent Claim 125 words
A process of producing veneer comprising the following steps: a. peeling logs in a peeling means to produce veneer; b. conveying said veneer from said peeling means to storage tray means; c. conveying said veneer from said storage tray means in a continuous edge-to-edge supply directly to a dryer; and d. drying said veneer in said dryer, wherein; said dryer has at least two levels of conveyors transmitting its length, the veneer peeled from the sap portion of the logs is conveyed to one set of said storage trays to supply one level of said dryer, and the veneer peeled from the heart portion of the logs is conveyed to a second set of said storage trays to supply a second level of said dryer.
