Abstract

An apparatus for guiding a piece of timber, especially a block (2) to be machined in a chipper canter. A chain conveyor (10) for conveying the block is provided in front of the chipper canter and at least one press roll (24, 26), for pressing the block against the chain conveyor. Between the chain conveyor and the chipper canter, there is a raisable and lowerable feed roll (14) which in its lower position is below the level of the chain conveyor and in its raised position is above said level. At an appropriate distance in front of and behind the chipper canter, there is a pair of side rollers (48, 50) the rollers of which (52, 56, 54, 58) can be pressed against the sides of the block in such a way that they center the block or move freely in the lateral direction.
