Abstract
A rotary stacker device for sequentially picking up and sequentially delivering plastic film products, onto mounting wickets. The rotary stacking device comprises a rotary hub upon which are mounted radially disposed work arms, with the arms having grid-like extension members for controllably positioning the film products during delivery and reducing air turbulence during the stacking process.
