Method of wrapping various products in packaging made from sheet material, a device for working the method, and packaging thus obtained.

摘要

The invention relates to a method of wrapping various products in packaging obtained from a strip. In the method, the strip (6) is longitudinally folded along its centre so as to form two longitudinal portions which are longitudinally coupled. The portions are then joined along transverse junction lines (15) which define compartments (16) having upwardly open mouths for inserting material. The compartments are then separated at the transverse junction lines (15), 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 (21) travelling along a closed path in a loop (22). According to the invention, the path travelled by the bags is inside the path of the conveyor (21) so that opposite corners of the bag mouths are brought together and consequently loosen the borders bounding the mouth so that metering means (33, 39) can be inserted along a circular portion (22) of the path of the conveyor (21) so that a preset amount of material can be discharged into the bags. After the metering means has been removed, the bags are closed and separated from one another. The invention also relates to a device for working the aforementioned method, and the resulting packaging.
