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.
