Abstract
A packaging machine is described which comprises a pair of squeezing guide rolls opposite each other and movable to and from a tubular plastic film, perpendicularly thereto; a pair of heat-sealing members located under the guide rolls and operating in the same manner; and a multi-purpose unit consisting of a compressing component, a cooling component and a cutting component. This unit is divided into two members operating similarly to the other parts of the machine. The film container, after having been charged is moved downwardly and guided first to the heat-sealing members, then to the compressing-cooling-cutting unit by drive rollers means. The displacements are effected for predetermined distances, so as to insure perfect sealing and severing of the containers.
