Definitions

  • the aim of this application is to register an improved drum for flexographic printing that incorporates significant innovations and advantages compared to the present printing drums.
  • said drum consists of a printing sheet capable of printing on the edge of the pottery and a system of retaining same.
  • printing machines are used that are made up of one or more drums. Said drums have the inked flexographic sheet rolled onto their outer surface. This sheet is made up mainly of a polymer or similar compounds.
  • the improved drum object of this present registration, for flexographic printing, eliminates the above stated disadvantages, both in regards the retention of the sheet and equally the printing onto the edges of pottery. This is because the drum has a reliable and convenient retaining device for the printing sheet, and a printing sheet capable of being used to print onto the edge of pottery.
  • the retaining device is held longitudinally on the drum for the housing of the elements that will retain the ends of the sheet. This will be carried out in such away that these elements do not protrude the shape.
  • Said retaining elements are made up of a lower support element, which is screwed directly onto the drum, and has tow rows of openings for the anchoring of some plates that retain the edge of the printing sheet with the lower support element.
  • Each fixing plate or element is made up of an element that extends along the length of the printing sheet.
  • each plate has some openings with countersinking for the insertion of an anchoring bolt for this plate to the support element.
  • an anchoring bolt for this plate to the support element.
  • Along the lower outer edge of the support there is an stepped arrangement to receive the edge of the printing sheet.
  • On the opposite side of this arrangement there is a protruding rib, in such a way that as the screws are tightened the plate progressively applies pressure to the stated edge of the sheet.
  • an upper cover is made up of a sheet element and which has its two longitudinal sides respectively bent over in a tab. This means that the retaining device remains below the surrounding level generated by the continuity of the external surround of the sheet in the cradle in which it is held.
  • protrusions In order to make the centring of the sheet easier, a series of protrusions have been provisioned on the edge and arranged at regular intervals. These protrusions are arranged in a combined manner with some hollows located in the groove for the trapping of the plate that holds said edge. In this way, on assembling the sheet onto the drum, it will be perfectly centred and said protrusions fitting into the corresponding countersinks and mortises.
  • the printing sheet is fitted with two rims arranged on the longitudinal edges of the outer face of same.
  • the rim diminishes in thickness in a progressive way towards the edge of the sheet.
  • This consists of an improved printing drum (1) for flexographic printing that is made up of a printing sheet (2) and a retaining device (3) for the printing sheet (2).
  • the retaining device (3) is held longitudinally on the drum (1) for the housing of the elements that retain the edges of the sheet (2).
  • Said retaining elements consist of a lower support element (4), which is screwed directly to the drum (1), and which has a series of openings (7) for the anchoring of the plates (5) that hold the edge of the printing sheet (2) with the lower support element (4).
  • Each fixing plate or element is made up of an element that extends along the length of the printing sheet.
  • each plate has some openings with countersinking (8) for the insertion of an anchoring bolt (9) for this plate to the support element.
  • an anchoring bolt (9) for this plate to the support element.
  • an anchoring bolt (9) for this plate to the support element.
  • an anchoring bolt (9) for this plate to the support element.
  • an anchoring bolt (9) for this plate to the support element.
  • an anchoring bolt (9) for this plate to the support element.
  • an anchoring bolt (9) for this plate to the support element.
  • an anchoring bolt (9) for this plate to the support element.
  • an anchoring bolt (9) for this plate to the support element.
  • stepped arrangement 10 to receive the edge of the printing sheet (2).
  • a protruding rib (11) On the opposite side of this arrangement (10) there is a protruding rib (11), in such a way that as the screws are tightened the plate progressively applies pressure to the stated edge of the sheet.
  • the plate has a series of spaced slots (12) centred on the bottom of the mentioned groove (10). Some protrusions (13) on the edge of the printing sheet (2) are housed in these slots (12).
  • the device is fitted with an upper cover (6), which is made of a sheet element that respectively has a tab bent over on its two longitudinal sides.
  • the printing sheet (2) is fitted with two rims arranged on the longitudinal edges of the outer face of same.
  • the rim diminishes in thickness in a progressive way towards the edge of the sheet.
