Definitions

  • the present disclosure relates to wrapping machines for wrapping loads with wrapping material, and more particularly to wrapping machines including tape applicators for securing the wrapping material to the load or to the pallet supporting the load.
  • Packaging lines include one or more of several different types of unitizing systems that unitize a load of goods by securing the goods together and, in certain applications, to a pallet.
  • These unitizing systems include stretch-wrapping machines that use rolls of plastic stretch film to unitize a load of goods.
  • Typical stretch-wrapping machines include a film carriage on which a replaceable roll of stretch film is mounted. To wrap the load of goods, the film carriage rotates relative to the load, or the load rotates relative to the film carriage (depending on the type of stretch-wrapping machine) while the film carriage vertically moves relative to the load. This relative movement pulls the stretch film from the roll and applies it to the load in a spiral pattern.
  • Str etch- wrapping machines can include pre-stretch assemblies that pre-stretch the stretch film along its longitudinal axis after it is pulled off of the film roll and before it is applied to the load. Pre-stretching the film before applying it to the load has several benefits, including increasing the film’s containment force such that the applied film tends to “contract” around the load to better unitize it and to avoid slipping off the load.
  • Paper wrapping material is one recyclable, eco-friendly alternative to plastic stretch film.
  • One problem with using paper wrapping material is that, unlike stretch film, the paper wrapping material is not elastic (or is minimally elastic) and cannot be pre-stretched. This lack of pre-stretch renders the applied paper wrapping material susceptible to slipping off the load in certain instances.
  • Various embodiments of the present disclosure provide a wrapping machine including a tape applicator and configured to apply wrapping material, such as paper wrapping material, to a palletized load and to apply tape to the wrapping material and the load and/or the pallet to secure the wrapping material to the load and/or the pallet.
