Definitions

  • This invention relates to a printer and in particular a printer for supports made of compostable material and relative printing method.
  • One known example is the bag for containing fruit and/or vegetables used in supermarkets.
  • the articles made of compostable material may, when used, be "contaminated" with other non-compostable materials which affect the compostability of the article itself.
  • the user Taking as reference the bag for containing fruit and/or vegetables used in supermarkets, the user will, generally, stick a label to the bag to keep track of information about the product contained, such as, for example, purchase price, weight and type of product, so as to be able to purchase the product.
  • the prior art labels are not compostable, since they comprise supports made of plastic material such as, for example, the silicone adhesive support, consequently the bag made of compostable material to which the label is attached becomes, however, no longer compostable.
  • the need has been felt of maintaining the compostability of the compostable supports, such as, for example, the bags for fruit and vegetable.
  • a printer of supports made of compostable material comprising an inlet opening configured for inserting a flap of the support made of compostable material, means for feeding said flap configured to pick up the flap introduced through the inlet opening and feeding it to an end of stroke position.
  • the feed means are configured to expel the flap through the inlet opening from the end of stroke position.
  • a thermal transfer printing unit comprising means for unwinding a reel of carbon-coated tape, a print head configured to heat up and a contact element of the head.
  • the head is configured to pass from a non-operating position, at which it is positioned raised relative to the contact element in such a way that the flap can advance through the gap defined by the head and by the contact element, to an operating position, at which the head lowers towards the contact element in such a way as to bring into contact a respective portion of the carbon-coated tape with the flap and it heats to release the ink of the carbon-coated tape on the flap.
  • the head passes from the non-operating position to the operating position during the expulsion of the flap through the inlet opening.
