FIELD: packaging industry.
SUBSTANCE: stacker with spiral sections for sheet material stacking, according to one of versions of invention, contains stacking wheel with sections for receiving of sheet material, helical located one over other around pivot pin, movable pusher, ejecting sheet material from sections of stacking wheel and receiving basis for stacking on it of sheet material. Additionally stacker is outfitted by guide at least partly enveloping stacking wheel. At first position of pusher sheet material is preliminarily is assembled into stack between circumference of stacking wheel and guide. At movement of pusher into the second position preliminarily assembled into stack sheet material is stacked on receiving basis. At pusher in the second position located in sections sheet material is laid into stack on receiving basis.
EFFECT: increasing efficiency and reliable performance of the device.
