Abstract
A running strip of cigarette paper or the like is provided with printed matter by the profiled peripheral surface of a printing roller which receives ink from one of several rollers including a pair of transfer rollers defining a nip which receives ink from an adjustable nozzle. The latter is movable back and forth longitudinally of the nip by an electric or other suitable motor receiving signals from a programmed control unit by way of an amplifier. The control unit regulates the speed of the nozzle and hence the distribution on, and the rate of delivery of printing ink to, the peripheral surface of the printing roller.

Apparatus for supplying a flowable mixture of a printing ink and a compressed gas to a printer for the application of printing ink to a running elongated strip of imprintable material in the form of a pattern the imprinting of which requires different amounts of printing ink applied crosswise in a running direction of the elongated strip, comprising:
- a nozzle having a mixture-receiving inlet and an outlet for directing the mixture against the printer;
- means for moving the strip;
- means for moving said nozzle crosswise relative to the strip at a speed based on the printing ink required for the pattern to be imprinted on the imprintable material;
- and
- means for supplying the mixture to said inlet in quantities based upon said speed.
Apparatus for supplying a flowable mixture of a printing ink and a compressed gas to a printer for the application of printing ink to a running elongated strip of imprintable material in the form of a pattern the imprinting of which necessitates the application of printing ink at a predetermined rate, comprising:
- a nozzle having a mixture-receiving inlet and an outlet for directing the mixture against the printer;
- means for moving the strip lengthwise;
- means for moving said nozzle relative to the strip, wherein said means for moving said nozzle comprises:
- an adjustable prime mover including an adjustable electric motor, and
- means for adjusting said prime mover based on said predetermined rate, wherein said adjusting means includes means for generating electric signals having characteristics dependent upon said predetermined rate and means for transmitting said electrical signals to said motor;
- and
- means for supplying the mixture to said inlet in quantities based upon said predetermined rate.
Apparatus for supplying a flowable mixture of a printing ink and a compressed gas to a printer for the application of printing ink to a running elongated strip of imprintable material in the form of a pattern the imprinting of which necessitates the application of printing ink at a predetermined rate, comprising:
- a nozzle having a mixture-receiving inlet and an outlet for directing the mixture against the printer;
- means for moving the strip lengthwise;
- means for moving said nozzle relative to the strip, wherein said means for moving said nozzle comprises means for reciprocating the nozzle at least substantially transversely of the moving strip, wherein said means for reciprocating said nozzle comprises a variable-speed electric motor and means for transmitting to said motor electric signals to regulate the speed of the motor based on said predetermined rate;
- and
- means for supplying the mixture to said inlet in quantities based upon said predetermined rate.
Apparatus for supplying a flowable mixture of a printing ink and a compressed gas to a printer for the application of printing ink to a running elongated strip of imprintable material in the form of a pattern the imprinting of which necessitates the application of printing ink at a predetermined rate, comprising:
- a nozzle having a mixture-receiving inlet and an outlet for directing the mixture against the printer;
- means for moving the strip lengthwise;
- means for moving said nozzle relative to the strip, wherein said predetermined rate is stored in a memory in the form of information which is addressed to operate said means for moving said nozzle, wherein said information is in the form of a reference-print page;
- means for optoelectronically scanning said image and for generating signals for transmission to said means for moving said nozzle;
- and
- means for supplying the mixture to said inlet in quantities which vary as a function of said predetermined rate.
