Abstract: An infeed system that orients a log for a processing unit. A flight conveyor, a log turner and a sharp chain are in an overlapping arraignment. The flight conveyor conveys a log past a scanner which inputs scan data into a computer which determines the profile and orientation on the flight conveyor. The computer determines the desired orientation of the log for the processing unit. The log turner is arranged to rotate and skew the log to the desired orientation. The log is then transferred to the sharp chain conveyor. The overlapping arrangement of the flight conveyor, log turner and sharp chain maintains full control of the log at all times. The sharp chain conveys the log past a second scanner which inputs the scan data to the computer to determine the actual orientation of the log on the sharp chain. The infeed system may also be provided with a shift and lift mechanism for further controlling the log position relative to the processing unit.

Abstract: A plate exchange apparatus for a printing press having one fixing unit for fixing one end of a plate and the other fixing unit for fixing the other end of the plate wound around the circumferential surface of a plate cylinder, one fixing unit and the other fixing unit being arranged in a gap in the circumferential surface of the plate cylinder, includes a plate holding apparatus, an old plate holding apparatus, and a new plate holding apparatus. The plate holding apparatus holds an old plate to be removed and a new plate to be supplied. The old plate removal member is arranged in a plate removal path of the old plate which is released from the fixing units and which is removed into the plate holding apparatus upon pivotal movement of the plate cylinder. The old plate removal member holds and moves the old plates one by one every plate replacement cycle and stacks and stores the old plates in the plate holding apparatus.
