Abstract: A guide arrangement for a drum-type cutting machine is composed of a guide block cooperating with a guide rail and articulated at the lower end of a vertical guide arm of the cutting machine. The guide block has a pocket defined by lateral walls which receives the guide arm. A transverse bolt extends through the pocket in the guide block and is received snugly by a bore in the guide arm. One of the end regions of the bolt forms a pivot journal head with curved surfaces which is received in a pivot journal socket in one of the lateral walls of the pocket in the guide block. The other end of the transverse bolt fits with lateral play in a horizontal guide of the other lateral wall of the guide block. The inner surfaces of the lateral walls incline relative to a horizontal plane to permit the guide arm to cant about a vertical axis.
