| 摘要 |
The invention relates to a folding module (13) intended for a machine (1) for producing mailing covers, comprising two counter-rotating folding rollers (18a, 18b) defining an area (ZR) for receiving at least one envelope document, an input area (20) and an output area (ZS) from which said folded envelope document is output according to a predefined folding line, and a support means (22) which is translatably movable perpendicular to the receiving area (ZR) between a passive position and an active position in which said means moves said envelope document from said receiving area (ZR) to the inside of said input area (20). A support roller (22') mounted such as to be freely rotatable at the end of said support means (22) accompanies, in the active position, said envelope document (4) without sliding until coming into contact with one of the folding rollers (18a, 18b) thus guaranteeing high folding accuracy. |
