ARRANGEMENTS FOR THE DEVELOPMENT AND ACCESSION OF A TAX FORM CONTAINING

摘要

In an apparatus for folding and closing a package having a gable-shaped folding closure having marginal areas forming a fillet seam, and including means for advancing the package past a working station, there is provided a pincer closing tool having jaws and handles, the tool advancing with the package. A wedge having two pairs of faces of different inclinations is forced downwardly to pivot the pincer jaws first to effect folding and then, under the greater force of the shallower inclination, pressing of the closure. A two-armed lever, one arm of which is connected to a toggle arm surrounded by a compression spring, controls the movement of the wedge. The pincers also move vertically toward the package during the closing operation.
