Abstract: Method, machine and installation for vacuum packaging of products, where a plurality of individual bags closed at one end and open at the opposite end with at least one product therein are generated. For generating the bags, a transverse cut and a complete transverse seal on both sides of the transverse cut are made on the film tube, and a transverse cut without complete transverse seals on the sides thereof is made at a distance (L) substantially equal to the desired length of the bag to be generated from the transverse cut and seal on both sides. Each bag is oriented at 180 degrees with respect to the bag previously generated in the forward movement direction.

Abstract: A skin packaging machine in which a first continuous film and a second continuous and thermoplastic film above the first film are supplied in a forward direction of the machine. The machine includes a sealing station configured for receiving both films, and it comprises an upper tool pressing on the films to seal them to one another, with a closed holding contour delimiting the area of said films being sealed. The sealing station further comprises a sealing gasket attached to the holding contour, the sealing gasket having, on each side with respect to the forward direction, an operation zone with a notched configuration which is facing the space delimited by said sealing gasket.

Abstract: Splicing method and unit for a packaging machine, whereby a first film is spliced to a second film which is a spare film. The splicing is performed by means of an adhesive element with two opposing adhesive surfaces, one for each film, and a longitudinal adhering element. First an adhesive surface is adhered to the adhering element and said adhering element moves so that the other adhesive surface comes into contact with the second film and adheres to it. Then the adhering element is separated from said second film, the adhesive element being adhered to said second film, and the first film is caused to come into contact with said adhesive element already adhered to the second film.

Abstract: A method and apparatus for vacuum packaging a product. According to one embodiment a film tube is generated, and, in the film tube a product (P) is introduced and at least one cut is made. In the method, a vacuum may also applied inside the film tube, and a transverse seal is formed therein, a film tube closed at one end being obtained upstream of the cut and a package closed at both ends being obtained downstream. Furthermore, the film tube is transversely pinched, a portion the inside of the film tube which is isolated from the inside of the rest of the film tube being obtained, and a chamber is demarcated around at least part of said portion, the vacuum being applied and the transverse sealing operation being performed inside said chamber.

Abstract: A modified atmosphere, skin or vacuum packaging machine comprising first feed means adapted for feeding a first film to the machine, second feed means adapted for feeding a second film to the machine, and a sealing station where the vacuum is formed and/or the modified atmosphere is introduced, and the second film is sealed to the first film to obtain a package. The machine comprises displacement means configured for moving at least the first film a driving distance from an initial position, holding down and driving at least the first film in the driving direction to an end position, said displacement means being configured for subsequently returning to the initial position when the machine is in operating mode.

Abstract: Format change method for a thermoforming machine and a thermoforming machine. A station of the machine includes an upper tool and a lower tool, at least one of the upper and lower tools being suitable for moving in a substantially vertical actuating direction during the operation of the machine. In the method, the upper tool is supported on the lower tool and both tools are subsequently withdrawn from the station and are replaced with new tools. When withdrawing the upper and lower tools from the station and when introducing the new tools therein, the tools are moved simultaneously and jointly in a replacement direction different from the actuating direction.

Abstract: A method for loading containers that involves intermittently shifting at least one first empty housing and one second empty housing of the containers between respective first and second rest positions. According to one embodiment the method involves calculating an available time td corresponding to the time necessary for an empty housing to reach a loading position of a manipulator and comparing the available time td with a positioning time necessary for the manipulator to collect from its current position each object to be loaded from a collecting area and depositing it in a loading position coinciding with the position of an empty housing of a container. The object to be collected and the delivery position of the object in an empty housing corresponds with a loading position of the manipulator in which the positioning time is closest to the available time td.

Abstract: A system for loading and unloading food products. In one implementation the system includes a transport device with a plurality of parallel belts upon which the products to be loaded move, and a tool adapted to load the products. The tool has a support adapted to pass through the gaps between the belts to load the product and to support the product when it is unloaded, and to perform the loading of the product moving it in an ascending vertical direction, the support lifting the product from the transport device. The support is adapted to rotate in relation to the support structure to unload the product, when they rotate, the support has a peripheral speed equal to the speed at which the product moves during the unloading.

Abstract: A packaging machine having a sealing member that acts on a product wrapped by a lower film and an upper film, and which seals or closes the films to each other around the product in order to vacuum-package said product between both films, and control means for causing the sealing member to move in order to package the product. The sealing member defines at least one inner space where the product to be vacuum-packaged is disposed wrapped at least partially by the two films. According to one implementation the sealing member includes at least one longitudinal first wall, a longitudinal second wall and a transverse wall between which the inner space is defined, and an unobstructed opening facing the transverse wall.

Abstract: A thermal seal packaging systems and methods thereof. In one implementation a thermal sealing packaging system has a container transfer unit for transferring a container which is to contain a package item, a measuring unit for measuring the weight of the item that is loaded in the container being transported before it is loaded into the container, a capping film supply unit for a capping film to cover the opening area of the container, an indication means for indicating the measurement data of the measurement unit on the capping film, and a sealing unit for heat-sealing an opening area of the container, into which the package item is loaded, with the capping film, the opening area of the container into which the item is loaded is covered by the capping film on which the corresponding measurement data is indicated.
