Claims8
A method for producing individual blanks from a foil film comprising:
- transporting the foil film by a first conveyor for feeding the foil film;
- using a second conveyor for transferring the individual blanks formed from the foil film;
- producing at least one parting line on the foil film in the first conveyor by a device producing the at least one parting line;
- feeding the foil film with the at least one parting line continuously to the second conveyor;
- and
- controlling a transport speed of the first conveyor relative to a transport speed of the second conveyor by a control device to form a tear separating the individual blank when the parting line is a guide system of the second conveyor;
- wherein the guide system and the second conveyor are arranged so that a tear in the foil film is guided and conveyed by the second conveyor;
- and
- wherein the guide system directly guides the tear separating the individual blank and the foil film behind the individual blank from the device producing the at least one parting line.
