ABSTRACT:
A method and apparatus for handling lengths of timber which are both green and dried include the feature of simultaneously conveying, by way of suitable conveyors, both the green timber and the dried timber to a given location from where the two different types of timber are conveyed together by way of a single conveyor beyond the given location to a drop sorter having compartments into which the green and dried timber are dropped according to a given program. From the drop sorter batches of green timber and batches of dried timber are received by batch conveyors which serve to convey these batches to a packaging apparatus which serve to provide from the batches of green timber packages in which layers of green timber are separated by spacers, preparatory to transmitting these packages to a drying installation, while the dried timber batches are formed into packages which are suitable for further handling. The packaging apparatus may include separate machines for the green timber and dried timber, or a single unitary packaging machine may be provided, according to a further feature of the invention, for alternately operating on the green timber and dried timber to provide therefrom packages as referred to above.
