  • Patent number: 4774797
    Abstract: The invention relates to a method of wrapping various products in packaging obtained from a strip. In the method, the strip is longitudinally folded along its center so as to form two longitudinal portions which are longitudinally coupled. The portions are then joined along transverse junction lines which define compartments having upwardly open mouths for inserting material. The compartments are then separated at the transverse junction lines, thus obtaining a set of independent bags which remain joined together at lateral areas near the mouth. The resulting bags are suspended from a conveyor travelling along a closed path in a loop. According to the invention, the path travelled by the bags is inside the path of the conveyor so that opposite corners of the bag mouths are brought together and consequently loosen the borders bounding the mouth so that metering means can be inserted along a circular portion of the path of the conveyor so that a preset amount of material can be discharged into the bags.
