Abstract
A printing press (10) has at least one electric motor (14), which is arranged at a distance of less than 0.5 m from an emission source (18). At least one explosion protection wall (22) is provided, such that the thread measure (F) between the emission source (18) and the electric motor (14) is greater than 0.5 m.
Claims20
A printing press comprising:
- at least one electric motor, the at least one electric motor being arranged at a distance of less than 0.5 meters from an emission source of solvent vapors, wherein the emission source is one or more of an anilox roller, a pressure cylinder, a chambered doctor blade bar, an ink tray, or an imprinted web of material;
- and
- at least one explosion protection wall, the at least one explosion protection wall enclosing the at least one electric motor on at least two sides of the at least one electric motor and having an opening on an opposite side of the at least one electric motor from the emission source;
- wherein a thread measure through the opening and between the emission source and the at least one electric motor is greater than 0.5 meters, wherein the thread measure is a shortest free path connecting two points to each other while skirting obstacles.
