ABSTRACT:
A synchronized wrapping machine which receives a series of articles to be wrapped and forms and heat seals a wrap of heat sealable material around each article. The incoming articles are longitudinally aligned and are thereafter conveyed in preselected spaced relation into a tube continuously formed of longitudinally overlapped heat sealable material, with the tube thereafter being heat sealed together and severed intermediate adjacent articles. The overwrapped articles are engaged by upper and lower article carrier holding cups and are transported longitudinally between upper and lower indexing conveyors which drive the article carriers. During traverse of the indexing conveyors, the overwrapped articles are turned 90.degree. by the article carriers and the severed ends of the wrapping are tucked and folded before engagement with an end sealer which heat seals the ends together. The wrapping of the articles is thereby accomplished through the machine in substantially continuous motion with a minimum of speed limiting vibration.
