Method and apparatus for sealing packages

摘要

An apparatus and method is disclosed for sealing in a single package bundles of product cartons which are conveyed in series along a moving conveyor belt. A stationary frame is aligned with the conveyor, and a movable carriage assembly is connected to the frame. Packages or cartons of product are stacked and bundled by film, such as thermoplastic film, in a series of sealing steps. The apparatus includes at least one motor mounted on the stationary frame and capable of engaging the carriage assembly to facilitate reciprocating movement of the carriage assembly in relation to the moving packages. A separate computer controlled servo motor drives the opening and closing of seal bars on the carriage assembly to seal the film at each end of the package.
