ABSTRACT:
The device for turning a front panel of a platelike workpiece within a folder-gluer comprises a retaining plate 20 extending across and somewhat above the traveling plane of the workpiece and a series of lifting fingers 30 positioned transversely below the travelling plane and somewhat upstream of the retaining plate 20. The lifting fingers are actuated by a piston from a resting position below the travelling plane to a raised slanted raised position, at the arrival of the blank's front panel. The front panel includes a partially separated flap that must be parted. The device also comprises at least one pusher 40 that is substantially perpendicular to the plate 20, the pusher 40 being actuated by an actuator 44 in order to separate the flap when the panel reaches maximum height against the plate 20.
