Abstract
Abstract Film tucking apparatus comprises a conveyor platform for a partially wrapped article having film wings extending beyond both sides of the article and overlying the platform. Pivotally movable with respect to the platform are a pair of tucking arms, one at each side of the article. These arms overlie the film wings and are pivoted to upward position permitting the article to be fed over the platform and to a position between the elevated arms and platform. The arms are lowered into contact with the film wings and the tucking arms are moved toward one another to sweep the film wings beneath the article. An elevator is provided beneath the article to lift it up during closing motion of the tucking arms.
