Abstract
A printing machine has at least one central impression cylinder, to which several inking units are allocated, in which a printing material sheet can be fed along a feed path to the impression cylinder in an area between a first inking unit and a last inking unit, and an unwinding station, from which the printing material sheet can be unwound, in which a passable area is provided between the impression cylinder and the unwinding station, at which the printing material sheet can be passed. Sound-absorbing elements are arranged above and/or beneath the feed path.
Claims13
A printing machine comprising:
- at least a central impression cylinder, to which a plurality of inking units are allocated, in which a printing material sheet is supplied to the central impression cylinder in an area between a first inking unit and a last inking unit along a feed path;
- an unwinding station, from which the printing material sheet is unwound;
- a passable area between the central impression cylinder and the unwinding station, at which the printing material sheet is passed;
- and
- sound-absorbing elements configured as a tunnel, through which the feed path extends,
- with an entry area of the sound-absorbing elements including a component that narrows a cross section of the feed path, said component being located at an end of the tunnel that is generally adjacent the central impression cylinder.
