Laboratory Performance of a Powered Back-Up Roll for Peeling Veneer.

Abstract

The objective of this study was to determine the effectiveness of the PBR in providing auxiliary torque to a veneer bolt. Specific goals were to: Measure the torque provided by the PRB in peeling veneer of different species and thickness. These were Douglas-fir and red oak, 1/32 inch and 1/10 inch each; and white fir, 1/8 inch and 3/16 inch. Evaluate the quality of veneer peeled using the PBR by examining uniformity of thickness, surface smoothness, and surface appearance. Evaluate roller coating material for friction characteristics, wear, and compatibility with wood. Develop optimum control criteria for the PBR to provide detection and correction for roller slip and deflection of the log.
