Abstract
A method of winding a web band in a machine for processing printing materials, including controlling the winding as a function of a diameter of a roll formed by the web band, as the diameter changes during the winding, includes determining, by a first sensor fastened to a frame of the machine, the position of a peripheral surface of the roll relative to the frame of the machine, and determining, by a second sensor fastened to the frame of the machine, the position of one of a center of the roll and of a peripheral surface of a spindle carrying the roll, relative to the frame of the machine; a winding device for performing the method; and a printing-material processing machine, such as a printing press, having the winding device.
Claims15
A method of winding a web band in a machine for processing printing materials, including controlling the winding as a function of a diameter of a roll formed by the web band, as the diameter changes during the winding, which comprises:
- determining, with a first feeler a position of a peripheral surface of the roll;
- determining, with a second feeler a position of one of a center of the roll and of a peripheral surface of a spindle carrying the roll;
- and
- monitoring a mutually relative position of the first feeler and of the second feeler using a sensor for monitoring mutually relative angular position.
A winding device for a machine for processing printing materials, comprising:
- a web band windable into a roll;
- a first feeler for monitoring a diameter of the roll being wound as the diameter changes during the winding;
- a second feeler for monitoring a position of one of a center of the roll and of a peripheral surface of a spindle carrying the roll;
- and
- a sensor assigned to said feelers for monitoring the mutually relative positions thereof.
A winding device for a machine for processing printing materials, comprising:
- a web band to be wound onto a roll;
- one feeler for monitoring a diameter of the roll being wound as the diameter changes during the winding, said one feeler being mounted to a machine frame;
- another feeler mounted to the machine frame to be pivotable coaxially with said one feeler;
- and
- a sensor associated with said one feeler and said other feeler for monitoring relative positions of said one feeler relative to said other feeler.
