| 摘要 |
This invention relates to an unpleating system for machines for molding, filling and automatic closing of flexible-film-based wrappings, characterized by the fact that it comprises two units (100) capable of sequenced travel toward and away from the transverse welding plane (S), which units (100) each hold at least one flexible jack (150) bearing a pulli ng mechanism (170), said jack (150) being slanted in relation to the transverse welding plane (S) and the direction of travel of the units (100) so that at the time of approach of the units toward the transverse welding plane (S), the jacks (150) will be retracted and the pulling mechanisms (170) automatically moved toward the outside.
