ABSTRACT:
A form-fill-seal packaging machine has not only the basic elements such as devices for transporting a film and longitudinally and transversely sealing it but also a former and a chute formed integrally together as a former unit which is made detachably attachable to the frame structure of the packaging machine by an attachment mechanism. The former unit has wedge-shaped members, and the attachment mechanism includes a mobile member constrained to move linearly and a lever which is attached to the frame structure such that a one-touch operation to rotate this lever causes this mobile member to move towards or away from the wedge-shaped members on the former unit and to engage with them or disengage from them.
