摘要: A battery of vertical band saws is adjustable to vary the spacing between bands and is used to both edge and resaw material. A preparation table upstream from the saws receives material from a recirculating conveyor or from a head rig, orients the material in the most desirable position for cutting and transfers the material endwise to an infeed table. The infeed table has toothed conveyor rolls for feeding the material positively into the saws, an overhead pneumatic roll for engaging the top of the material while edging and driven side press rolls for pressing the material against a line bar when resawing. Downstream from the saws an edge picker table has a pair of longitudinal separating plates normally aligned with the two outside saws for separating edge trimmings from the material to be processed into lumber. The plates are withdrawn from alignment with the saws when resawing. A sweep table receives material from the edge picker table and includes sweep fingers which sweep across the table for transferring material sideways to the recirculating conveyor and pivot downwardly to permit transfer of material endwise from such table.
