Abstract
Abstract A moving web is marked at spaced locations by a rotatable print head that is intermittently displaced into contact with the web during angular displacement between two rest positions by means of a signal controlled clutch drivingly connecting the print head to a driver driven by the movement of the web. In the rest positions of the print head, a print face is momentarily engaged by an ink storing device that is displaced from a retracted position.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
176 words
In combination with a moving web, a rotary marking device adapted to mark the web by rolling contact therewith at spaced locations along the direction of travel thereof, including a print head, means rotatably mounting the print head for angular displacement from a rest position along a predetermined path establishing contact with the web, drive means powered by the movement of the web connected to said mounting means and including means for selectively and intermittently causing the displacement of the print head along said path to establish momentary contact with the web, an ink storing device for transferring ink to the print head when in contact therewith, means mounting the ink storing device for displacement between a retracted position and an extended position contacting the print head in the rest position thereof, and ink transfer control means for momentarily displacing the ink storing device to said extended position prior to said displacement of the print head from the rest position whereby the drag imposed on the web by the print head during printing contact is minimized.
Claim 2
Dependent Claim
176 words
In combination with a moving web, a rotary marking device adapted to mark the web by rolling contact therewith at spaced locations along the direction of travel thereof, including a print head, means rotatably mounting the print head for angular displacement from a rest position along a predetermined path establishing contact with the web, drive means powered by the movement of the web connected to said mounting means and including means for selectively and intermittently causing the displacement of the print head along said path to establish momentary contact with the web, an ink storing device for transferring ink to the print head when in contact therewith, means mounting the ink storing device for displacement between a retracted position and an extended position contacting the print head in the rest position thereof, and ink transfer control means for momentarily displacing the ink storing device to said extended position prior to said displacement of the print head from the rest position whereby the drag imposed on the web by the print head during printing contact is minimized.
Claim 3
Dependent Claim
33 words
The combination of claim 1 including signal operated control means connected to the drive means for synchronizing said displacements of the print head and the ink storing device with movement of the web.
Claim 4
Dependent Claim
51 words
The combination of claim 2 including nozzle means rendered operative to direct a stream of drying fluid onto the web forwardly of the print head in said direction of travel, and valve means for rendering the nozzle means inoperative during displacement of the ink storing device to the extended position thereof.
Claim 5
Dependent Claim
62 words
The combination of claim 3 wherein said ink transfer means comprises spring means continuously biasing the ink storing device to the extended position, releasable retaining means for holding the ink storing device in said retracted position against the bias of said spring means, a source of fluid under pressure, and fluid operated means connected to said source for releasing the retaining means.
Claim 6
Dependent Claim
29 words
The combination of claim 4 wherein said valve means is connected to the source for simultaneous supply of the fluid to the nozzle means and the fluid operated means.
Claim 7
Dependent Claim
38 words
The combination of claim 5 including a second print head carried by said rotatable mounting means in angularly spaced relation to the first mentioned print head for alternate contact with the web and with the ink storing device.
Claim 8
Dependent Claim
39 words
The combination of claim 6 wherein said drive means includes a friction wheel in continuous contact with the web, and signal operated means coupling the friction wheel to the rotatable mounting means for limited angular displacement during marking cycles.
Claim 9
Dependent Claim
42 words
The combination of claim 7 wherein said signal operated control means includes signal transmitting switch means connected to the coupling means and the valve means for sequentially rendering the drive means and the ink transfer means operative during spaced intervals of time.
Claim 10
Dependent Claim
33 words
The combination of claim 2 wherein said signal operated control means includes signal transmitting switch means for sequentially rendering the drive means and the ink transfer means operative during spaced intervals of time.
Claim 11
Dependent Claim
51 words
The combination of claim 1 including nozzle means rendered operative to direct a stream of drying fluid onto the web forwardly of the print head in said direction of travel, and valve means for rendering the nozzle means inoperative during displacement of the ink storing device to the extended position thereof.
Claim 12
Dependent Claim
62 words
The combination of claim 10 wherein said ink transfer means comprises spring means continuously biasing the ink storing device to the extended position, releasable retaining means for holding the ink storing device in said retracted position against the bias of said spring means, a source of fluid under pressure, and fluid operated means connected to said source for releasing the retaining means.
Claim 13
Dependent Claim
29 words
The combination of claim 11 wherein said valve means is connected to the source for simultaneous supply of the fluid to the nozzle means and the fluid operated means.
Claim 14
Dependent Claim
62 words
The combination of claim 1 wherein said ink transfer means comprises spring means continuously biasing the ink storing device to the extended position, releasable retaining means for holding the ink storing device in said retracted position against the bias of said spring means, a source of fluid under pressure, and fluid operated means connected to said source for releasing the retaining means.
Claim 15
Dependent Claim
38 words
The combination of claim 1 including a second print head carried by said rotatable mounting means in angularly spaced relation to the first mentioned print head for alternate contact with the web and with the ink storing device.
Claim 16
Dependent Claim
39 words
The combination of claim 3 wherein said drive means includes a friction wheel in continuous contact with the web, and signal operated means coupling the friction wheel to the rotatable mounting means for limited angular displacement during marking cycles.
Claim 17
Dependent Claim
42 words
The combination of claim 15 wherein said signal operated control means includes signal transmitting switch means connected to the coupling means and the valve means for sequentially rendering the drive means and the ink transfer means operative during spaced intervals of time.
Claim 18
Dependent Claim
39 words
The combination of claim 1 wherein said drive means includes a friction wheel in continuous contact with the web, and signal operated means coupling the friction wheel to the rotatable mounting means for limited angular displacement during marking cycles.
Claim 19
Dependent Claim
138 words
In combination with a moving web, a rotary print head, web driven means rendered operative to displace said print head into momentary contact with the web and ink supply means engageable with the print head for inking the same preceding said momentary contact; signal-controlled means intermittently connecting the web driven means to transmit drive from the web to the print head for effecting said momentary contact during web-loading intervals of limited duration, ink transfer means connected to the ink supply means for momentarily effecting said engagement of said ink supply means with the print head, and automatic control means connected to the transfer means for limiting said momentary engagement to inking intervals immediately preceding each of the web-loading intervals to insure imprinting of the web without simultaneous loading thereof by the signal-controlled means and the ink transfer means.
