Working station with a cutting tool for quickly cutting a width of film

A method for operating a working station for a packaging machine for sealing trays and for cutting a top film, said method comprising:

• restraining a movement of a movable cutting tool with a holding mechanism;
• accumulating potential energy in at least one energy storage device by moving a sealing frame relative to the movable cutting tool;
• and
• releasing the holding mechanism to convert the accumulated potential energy into kinetic energy of the cutting tool.

A working station for a packaging machine for sealing trays with a top film, the working station comprising:

• a sealing tool upper part;
• a sealing tool lower part cooperable with the sealing tool upper part to form a sealing chamber;
• a sealing frame associated with the sealing tool upper part and movable relative to the sealing tool upper part;
• a movable cutting tool associated with the sealing tool upper part, the cutting tool having a blade for cutting a top film;
• and
• at least one energy storage device operably engaged with the cutting tool and the sealing frame, wherein the at least one energy storage device is disposed between the cutting tool and the sealing frame for accumulating potential energy upon a relative movement of the sealing frame with respect to the cutting tool.
