A drum barker including a cylindrical drum having debarking means. The drum is supported by wheels on both sides, the wheels including elastic outer portions. A guide ring assembly is provided on the drum periphery for contacting wheel portions to resist axial drum movement. The guide ring assembly includes at least two guiding faces which extend obliquely from the drum periphery in a direction away from the wheel portions to reduce wearing of the wheel portions and to cushion the forces imparted during axial contact of the wheel portions and guide faces.
