<p>CONTROLLED TRANSVERSELY MOVABLE GUIDE MEANS FOR LUMBER Precision guide means for accurately directing lumber to and/or receiving cut lengths from saws. The guide means is mounted for selective movement by networks back and forth across a path along which the lumber moves. A closed hydraulic system includes pistion-cylinder units with a unit near each of opposite ends of the guide means. One end of each cylinder unit is fixed against movement and the opposite end thereof is connected to the adjacent end of the guide means, and pipe means interconnects these cylinder units so that when the guide means is moved, hydraulic fluid is transferred from an end of one of the units to an opposite end of another unit to ensure that both ends of the guide means move exactly the same distance. The guide means can be a linebar and a tailbar interconnected by the hydraulic system so that they are moved in unison exactly the same distance by the setworks. The guide means can be or include a relatively long splitter.</p> |
