Abstract: A squaring-up device for a package converting line, located between a blank folding section and a folded-blank assembly section. The device has a frame, at least one jogger, having a deployed active position for correcting a geometry of a folded blank, and a drive for transporting the jogger. The squaring-up device includes an effector for moving the jogger from the active position to a retracted inactive position, and vice versa, and control the effector.

Abstract: The invention concerns a machine comprising driving means (14, 16, 18) for driving sheets in a drive direction (F) through a processing zone (T), and processing means including a tool (53, 53?) and a counter tool (56), respectively, borne by a first and by a second transverse rotary support shaft (52, 54). Said processing means are designed to produce in the sheets cutouts and folds transverse to their drive direction. The counter tool has a substantially cylindrical surface having at least one working strip (57) which extends parallel to the axis of the second support shaft and is radially offset relative to the portions (58) of said surface which are adjacent to said strip, the latter being designed to cooperate with the tool to form a cutout or a fold in a sheet.

Abstract: A machine for treating sheets, said machine comprising drive means (14, 16, 18) for driving the sheets, treatment tooling (52, 62) for forming cutouts or folds in said sheets that extend transversely to the drive direction (F) in which the sheets are driven. The treatment tooling is carried by at least one carrier shaft (52, 62) driven by a shaft motor (M52, M62). The sheets are driven at a substantially constant drive speed through the machine, and said machine further comprises a control unit (UC) which, as a function of said drive speed, and of information relating to the position of a sheet in the machine, control the shaft motor (M52, M62) such that, for treating said sheet, the tooling is in contact with a predetermined region of the sheet and is driven at a treatment speed whose tangential component is equal to the drive speed at which the sheet is driven.
