Abstract

A printing system comprises a first bearing support for a first media roll of a first print medium and a second bearing support for a second media roll of a second print medium. Said first and second bearing supports are spaced apart from one another. A first print transport path extends from the first bearing support from the first media roll to a main transport path of the printing system. A second print transport path extends from the second bearing support to the main transport path of the printing system. An attachment transport path extends between the first and the second bearing support. The attachment transport path allows both print media to be brought together and attached to one another. Thereby, a relatively stiffer medium may be attached as a leader section to a relatively weaker medium.

Claims15

Dependent claims

A printing system, comprising:

a printing assembly for depositing an image on web-based media, positioned along a main transport path of the printing system;
a first bearing support arranged for rotatably supporting a first media roll of a first print medium;
a second bearing support arranged for rotatably supporting a second media roll of a second print medium, said first and second bearing supports being spaced apart from one another;
a first print transport path extending from the first bearing support for transporting the first print medium from the first media roll to the main transport path of the printing system;
a second print transport path extending from the second bearing support for transporting the second print medium from the second media roll to the main transport path of the printing system, wherein the first transport path bypasses the second transport path and the second media roll;
an attachment transport path extending between the first and the second bearing supports and spaced apart from the first transport path, and
a web feeding system for transporting at least one of the first and second print media from a respective one of the first and second media rolls to the printing assembly.

4 more elements

A method for feeding a web-based medium into a printing system, the method comprising the steps of:

transporting a first print medium from a first print medium roll and a second print medium from a second medium roll to one another via an attachment transport path;
attaching a leader section of a predefined length of the second print medium to the first print medium;
positioning the leader section attached to the second print medium with respect to one of a first and second transport path, which first and second transport paths are separate from the attachment transport path;
and
transporting the leader section attached to the first print medium via the one of the first and second transport path to an inkjet printing assembly of the printing system.
