A method for manufacturing plywood includes receiving a face sheet on a main conveyor and feeding a plurality of pieces of core veneer onto a veneer conveyor by an automated core veneer feeder. The method also includes removing one or more of the plurality of pieces of core veneer from the veneer conveyor and placing the one or more of the plurality of pieces of core veneer onto the face sheet.

The present invention concerns the sector of leather treatment or working lines, in particular but not exclusively to tannery processings. In particular, the invention relates to a tendentially automatic or semi-automatic apparatus for loading incoming leathers on one of these lines, the apparatus being provided with means for lifting and advancing individual leathers starting from a stacking station, and with systems for the spread out and sequential arrangement of the single leathers on a conveyor surface of the line, downstream of the apparatus.

A bag supply device used in a rotary bag-filling packaging machine and including: an empty-bag holding member (9) for holding a bag (B), a reciprocating mechanism (13) for moving the empty-bag holding member back and forth between a bag receiving position and a bag delivery position, a first turning mechanism (14) for turning the empty-bag holding member around a first axis (O.sub.1) parallel to a bag width direction thereof upon operation of the reciprocating mechanism and orienting the holding face of the empty-bag holding member vertically in the delivery position, and a second turning mechanism (15) for turning the empty-bag holding member around a second axis (O.sub.2) parallel to a bag length direction thereof and causing the bag held by the empty-bag holding member in the delivery position to be directly across from the pair of grippers stopped in the empty bag supply position.

A single-sheet lifter includes a base frame arranged in a vicinity of a loading area and extending vertically, a separation unit configured to separate an uppermost workpiece from a plurality of the workpieces loaded in the loading area by means of at least one of an injection pressure of air and a suction force, and a counter balancer configured to reduce a weight acting on the separation unit. The separation unit is provided to the base frame so as to be able to move up and down. The separation unit includes a contact member that comes into contact with a surface of the uppermost workpiece. The separation unit is configured to go up following a lifting operation of a workpiece suction lifter and be retracted from above the loading area when the workpiece suction lifter sucks the surface of the uppermost workpiece to lift the workpiece.
