Described is a device for treating products, which includes a tool and a movable support of the tool for treating products. Each support is slidably mounted along a rail and includes a blocker that can be actuated by locking, an actuator for locking and unlocking the blocker, a power supply for the actuator, at least one member for coupling with said support, a relative and indexed motorization between the member and the support. The member incorporates the actuator, allowing power to be supplied to the blocker.

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.
