Abstract
In a packaging apparatus, articles are collated and formed into a module on a carriage assembly and are transported into a draped wrapping film and to means for sealing the wrapped module. Common movement of the sides of the carriage assembly are provided so as to ensure the stability of the collated article pattern. The draped wrapping film is under tension and is aligned with respect to the direction of travel of the carriage assembly. Side and transverse rear sealing of the wrapped module is provided, and the means for rear sealing the module also cuts the wrapping film and splices the unused wrapping film for return to its draped position. The wrapped and sealed module is transferred by a conveyor means from its wrapping position to a means for shrinking the wrapping film over the article module.
