Abstract
Abstract A scanner senses the position of the individual images on the web. A cutting cylinder position is monitored by a signal generator, and may be altered by mechanically changing the phase of the cutting cylinders in relation to the image on the web based on commands relating to the image registration error, the first derivative of the image registration error and/or the second derivative of the image registration error.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
148 words
A method for maintaining the register of images on a running web with a web processing device of the machine comprising the steps of: measuring a position of each image on the web; generating a reference signal corresponding to a desired position of each image on the web; creating a registration error data stream corresponding to the difference between the measured image positions and the reference signals; continuously sending control commands to the web processing device based on at least the registration error data stream; creating a speed command data stream by calculating changes in the registration error data stream and sending control commands to the web processing device based on the speed command data stream; and creating a torque command data stream by calculating changes in the speed command data stream and sending control commands to the web processing device based on the torque command data stream.
Claim 2
Independent Claim
148 words
A method for maintaining the register of images on a running web with a web processing device of the machine comprising the steps of: measuring a position of each image on the web; generating a reference signal corresponding to a desired position of each image on the web; creating a registration error data stream corresponding to the difference between the measured image positions and the reference signals; continuously sending control commands to the web processing device based on at least the registration error data stream; creating a speed command data stream by calculating changes in the registration error data stream and sending control commands to the web processing device based on the speed command data stream; and creating a torque command data stream by calculating changes in the speed command data stream and sending control commands to the web processing device based on the torque command data stream.
Claim 3
Dependent Claim
24 words
The method as recited in claim 1 wherein the measuring of the position of the images of the web is performed in sample sets.
Claim 4
Dependent Claim
16 words
The method as recited in claim 1 wherein the web processing device is a cutting cylinder.
Claim 5
Independent Claim
118 words
A method for maintaining the register of images on a running web with a web processing device of the machine comprising the steps of: measuring a position of each image on the web; generating reference signal corresponding to a desired position of each image on the web; creating a registration error data stream corresponding to the difference between the measured image positions and the reference signals; continuously sending control commands to the web processing device based on at least the registration error data stream; and creating a torque command data stream by calculating the second derivative of the registration error data stream and sending control commands to the web processing device based on the torque command data stream.
Claim 6
Independent Claim
118 words
A method for maintaining the register of images on a running web with a web processing device of the machine comprising the steps of: measuring a position of each image on the web; generating reference signal corresponding to a desired position of each image on the web; creating a registration error data stream corresponding to the difference between the measured image positions and the reference signals; continuously sending control commands to the web processing device based on at least the registration error data stream; and creating a torque command data stream by calculating the second derivative of the registration error data stream and sending control commands to the web processing device based on the torque command data stream.
Claim 7
Dependent Claim
24 words
The method as recited in claim 1 wherein the measuring of the position of the images of the web is performed in sample sets.
Claim 8
Dependent Claim
29 words
The method as recited in claim 5 wherein the number of images in a sample set is determined based on the minimum response time of the web processing device.
Claim 9
Dependent Claim
16 words
The method as recited in claim 1 wherein the web processing device is a cutting cylinder.
Claim 10
Independent Claim
106 words
A method for maintaining the register of images on a running web with a web processing device of the machine comprising the steps of: measuring a position of each image on the web; generating a reference signal corresponding to a desired position of each image on the web; creating a registration error data stream corresponding to the difference between the measured image positions and the reference signals; creating a torque command data stream by calculating the second derivative of the registration error data stream; and sending control commands to the web processing device, the control commands at least being based on the torque command data stream.
Claim 11
Independent Claim
106 words
A method for maintaining the register of images on a running web with a web processing device of the machine comprising the steps of: measuring a position of each image on the web; generating a reference signal corresponding to a desired position of each image on the web; creating a registration error data stream corresponding to the difference between the measured image positions and the reference signals; creating a torque command data stream by calculating the second derivative of the registration error data stream; and sending control commands to the web processing device, the control commands at least being based on the torque command data stream.
Claim 12
Dependent Claim
24 words
The method as recited in claim 8 wherein the measuring of the position of the images of the web is performed in sample sets.
Claim 13
Dependent Claim
16 words
The method as recited in claim 8 wherein the web processing device is a cutting cylinder.
Claim 14
Dependent Claim
22 words
The method as recited in claim 8 wherein the control commands are at least based directly on the registration error data stream.
Claim 15
Dependent Claim
42 words
The method as recited in claim 8 further comprising the step of creating a speed command data stream by calculating changes in the registration error data stream, wherein the control commands are at least based directly on the speed command data stream.
