Abstract
A device for coating a sheet comprises at least one screen cylinder configured to be positioned downstream of a sheet feeding mechanism. The screen cylinder is further configured to coat a sheet. The device further comprises a constant conveyor for feeding a sheet from the feeding mechanism to the screen cylinder and a variable speed drive for rotating the screen cylinder. The variable speed drive is configured to rotate the screen cylinder based on one of a print length and a print position of the sheet to be coated.
Claims38
A method of coating a sheet, comprising:
- providing a rotatable screen cylinder;
- force feeding at least one sheet to the screen cylinder;
- rotating the screen cylinder;
- coating the at least one sheet via the screen cylinder;
- and
- controlling the rotation of the screen cylinder based on the force feeding movement of the at least one sheet so as to promote accurate positioning of the at least one sheet relative to the screen cylinder during the coating of the at least one sheet.
A device for coating a sheet, comprising:
- at least one screen cylinder positioned downstream of a sheet feeding mechanism, the screen cylinder being configured to coat a sheet;
- a constant speed conveyor for feeding a sheet from the feeding mechanism to the screen cylinder;
- and
- a variable speed drive for rotating the screen cylinder,
- wherein the variable speed drive is configured to rotate the screen cylinder based on one of a print length and a print position of the sheet to be coated.
A device for coating a sheet, the device comprising:
- means for force feeding at least one sheet to a screen cylinder for coating the at least one sheet via the screen cylinder;
- means for rotating the screen cylinder;
- and
- means for controlling the rotation of the screen cylinder based on a least one of a print length and a print position of the at least-one sheet.
