  • the known packaging apparatuses of the kind mentioned hereto are used, in general, to package editorial products, like e.g. magazines, books, folders and the like or covers of any kind and nature whatsoever.
  • Such apparatuses comprise various processing stations, operating in sequence on the flow of products, like e.g.: a wrapping station, in which the film is positioned with respect to the flow itself and just wrapped about the products; a longitudinal sealing station, in which longitudinal edges of the film are sealed the one to the other parallelly to the flow direction, so as to form a sort of continuous tube wrapping the products; and a transversal sealing station, in which transversal edges of the film are sealed the one to the other orthogonally to the feed direction of the flow, so as to enclose the products into respective separate sealed wrappings.
  • a wrapping station in which the film is positioned with respect to the flow itself and just wrapped about the products
  • a longitudinal sealing station in which longitudinal edges of the film are sealed the one to the other parallelly to the flow direction, so as to form a sort of continuous tube wrapping the products
  • a transversal sealing station in which transversal edges of the film are sealed the one to the other orthogonally to the feed direction of the flow, so as to enclose the products into respective
  • any heat-sensitive film exhibits an optimal melting temperature range, of from 120 to 200 0 C for the most commonly used films.
  • the heat sealer of the transversal sealing station should remain into contact with the film portions to be sealed for a predetermined time period.
  • the heat sealer in order to utilize a flow of movable products uninterruptedly and not by fits and starts, i.e., to operate according to a continuous processing cycle, the heat sealer must be movable in the feed direction of the flow of products.
  • the sequence of the positions that the heat sealer assumes during said transversal sealing operation defines a so-called sealing cycle.
  • Such a sealing cycle may be conceived as subdivided into two main steps. In a first step, definable as contact step, the heat sealer is into contact just with the transversal portions of the film to be sealed and therefore the actual transversal sealing is carried out, via heat transmission by conduction between heat sealer and film.
  • this contact step should last enough to transmit to the film the quantity of heat required for its melting, at the temperature most suitable for the material of which the film itself is made of.
  • the detachment, from said single tubular wrapping, of a wrapping that packages an individual product is also provided.
  • a second step of the transversal sealing cycle starts, called return step, in which the heat sealer has to move both in a direction orthogonal to the bearing plane, to move away from the sealed film, and in the direction of the flow of products, in a sense opposed thereto, to return to a position useful for a new sealing, i.e. the cycle start position.
  • return step the heat sealer lowers again to contact the heat-sensitive film.
  • the heat sealer should possess a trajectory resulting from the combination of two motion components, i.e. a component of reciprocating motion along the feed direction of the flow of products to be packaged and a motion component in a direction substantially orthogonal to said feed direction.
  • transversal sealing station is used also when a heat transmission between heat sealer element and film is provided by irradiation rather than by conduction.
  • this different heat transmission mode entails alike problems, having to take place with a predetermined distance between heat sealer element and film.
  • the kind of driving means used in known apparatuses by causing said elliptical trajectory with non-independent motion components, forces the heat sealer to continual accelerations and decelerations. Therefore, during the contact step or generally that of transmission of heat to the film, the speed of the heat sealer is generally not equal to the speed of the flow of products, i.e. to the speed of the heat- sensitive film. This causes relevant imperfections in the transversal sealing. In fact, when a speed of the heat sealer is higher than that of the flow of products the film can tear, or holes and/or cumbersome stringy appendages can be generated.
  • the technical problem underlying the present invention is to provide a film packaging apparatus and method overcoming the drawbacks mentioned hereto with reference to the known art. Such a problem is solved by a film packaging apparatus according to claim 1 and by a method according to claim 26.
  • the present invention provides several relevant advantages.
  • the main advantage lies in that it allows to obtain a heat sealer speed substantially constant in the feed direction of the products during the contact step of the transversal sealing cycle, speed that therefore can be set substantially equal to that of the flow of products, i.e. of the heat-sensitive film.
