Abstract
The present invention relates to an inversion transfer module (60) for a converting machine having a printing module (16) comprising a first printing unit (17) arranged to print on a top side (S1) of the sheet (1), and a second printing unit (17′) arranged to print a bottom side (S2) of the sheet. The inversion transfer module is arranged between the first printing unit and the second printing unit and comprises a first inversion vacuum transfer (62) arranged to contact the first side of the sheet and a second inversion vacuum transfer (64) configured to contact the second side of the sheet, whereby the inversion transfer module is configured to change the side of adherence and transportation of the sheet.
Claims11
An inversion transfer module for a converting machine having a printing module comprising:
- at least one first printing unit having a top printing cylinder arranged to print on a top side of a sheet, and
- at least one second printing unit having a bottom printing cylinder arranged to print a bottom side of the sheet,
- the inversion transfer module being configured to convey the sheet between the at least one first printing unit and the at least one second printing unit, and
- wherein the inversion transfer module comprises an inlet inversion vacuum transfer and an outlet inversion vacuum transfer, each configured to contact and transport a different side of the sheet,
- whereby the inversion transfer module is configured to change the side of adherence and transportation of the sheet, and
- a pivotably movable locking part connected to a housing of the inversion transfer module, wherein the pivotably movable locking part is configured to engage with a corresponding mating geometry in a printing module to mechanically connect the housing of the inversion transfer module with a housing of the printing unit.
