Abstract
A method of tensioning a print medium on a drum comprising: supporting the medium on the drum; rotating the drum; and applying a gaseous flow to the medium on the drum, the gaseous flow having a major component that is tangential to the drum and in a direction that is opposite to the linear direction of the surface of the drum.
Claims3
A method of tensioning a print medium on a drum comprising:
- supporting the medium on the drum;
- rotating the drum;
- and
- applying a gaseous flow to the medium on the drum, the gaseous flow having a major component that is tangential to the drum and in a direction that is opposite to the linear direction of the surface of the drum;
- and
- controlling the temperature of the gaseous flow.
3 more elements
A printing apparatus comprising a drum for receiving a print medium and a nozzle directed substantially tangentially at the drum;
- in which said nozzle is positioned such that a gaseous flow exits said nozzle to pass over said print medium when said print medium is disposed on said drum, said gaseous flow having a major component tangential to said drum that creates tension along a length of said print medium disposed on said drum;
- and
- a cooler operable to cool gas before the gas exits the nozzle in said gaseous flow.
