  • Patent number: 4398580
    Abstract: A veneer lathe charger system utilizing automated equipment for scanning and positioning a log to obtain optimum production of veneer therefrom. The charger has mechanical features specially designed to provide a degree of accuracy in the physical manipulation of the log comparable to the degree of accuracy provided by the automated scanning and positioning equipment. These include log manipulation features emphasizing engagement of the log only at its opposing ends during and after scanning and especially during transfer from one manipulating device to another, avoidance of end engagement by two different manipulating devices in identical end areas of the log, minimal movement of log positioning devices by the employment of dual scanning steps and features for retaining the accuracy of the manipulation devices despite wear thereof. The charger further includes features for improving its rate of production by reducing time delays between successive log manipulating steps.
