Liebl.) with a 9.3% representation in the Slovak forests is an important wood material for the wood industry and pulp and paper industry. Oak bark with the structure and properties is completely different from the wood. Therefore the processing of logs is often necessary to separate the bark from the wood. The work evaluated shear strength on the interface wood / bark, in the course of year in the longitudinal and tangential direction, on the two moisture levels. The lowest shear strength values were found in the growing season fresh in tangential load. In the dormant period it was recorded almost twice a big the average value of the shear strength compared to the growing season. The values of shear strength in the longitudinal direction were approximately half higher than in the tangential direction. The values of shear strength in the dry state (w = 12%) grew on average compared to the fresh state in the longitudinal direction approximately about 280 %, and in the tangential direction about 360 %. Shear infringement was observed at the beginning of the growing season observed in the zone of early phloem. Based on analysis of shear area, it can be assumed that especially multiseriate phloem rays, significantly affect the adhesion at the interface wood / bark.
