Abstract:
Method for the packaging of articles with a plastic film which is based on the use of a packaging machine equipped with transverse welding devices arranged along a longitudinal direction where the method involves the steps of (a) positioning the articles on a conveyor belt with pushers activated by a motor; (b) distancing the articles from one another to provide a constant space or pitch; (c) feeding the plastic film, in the direction of the conveyor belt; (d) longitudinally welding the film in the direction articles on the conveyor belt; (e) activating the motor group situated downstream with respect to the welding device to weld and separate the film in the space between articles; and (f) activating the motor group of the welding device situated upstream with respect to another welding device to weld and separate the film in the space between the articles.
