Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
113 words
A device for controlling a web in a printing press, comprising: a supply roll of the web; a printing roll of the press; means for detecting a power loss of the press; and means responsive to the detecting means for controlling the tension of the web in the event of the power loss, including first means for driving the supply roll, and in which the controlling means controls the speed of the driving means, and including second means for driving the printing roll, and in which the controlling means controls the ratio of the first and second drive means to maintain the tension in the web in the event of the power loss.
Claim 2
Independent Claim
113 words
A device for controlling a web in a printing press, comprising: a supply roll of the web; a printing roll of the press; means for detecting a power loss of the press; and means responsive to the detecting means for controlling the tension of the web in the event of the power loss, including first means for driving the supply roll, and in which the controlling means controls the speed of the driving means, and including second means for driving the printing roll, and in which the controlling means controls the ratio of the first and second drive means to maintain the tension in the web in the event of the power loss.
Claim 3
Dependent Claim
18 words
The device of claim 1 wherein the controlling means controls the speed of unwinding of the printing roll.
Claim 4
Dependent Claim
26 words
The device of claim 1 including first means for driving the supply roll, and in which the controlling means controls the speed of the driving means.
Claim 5
Dependent Claim
24 words
The device of claim 1 including means for maintaining a desired tension in the web in the absence of power loss of the press.
Claim 6
Dependent Claim
17 words
The device of claim 4 wherein the maintaining means controls the rotational speed of the supply roll.
Claim 7
Dependent Claim
34 words
The device of claim 1 including means for driving the printing roll, and in which the controlling means drives the supply roll at a speed proportional to the rotational speed of the printing roll.
Claim 8
Independent Claim
89 words
A device for controlling a web in a printing press, comprising: a supply roll of the web; a printing roll of the press; means for detecting a power loss of the press; and means responsive to the detecting means for controlling the tension of the web in the event of the power loss, including first means for driving the supply roll, and in which the controlling means controls the speed of the driving means, and in which the first driving means controls the rotational speed of the supply roll.
Claim 9
Independent Claim
89 words
A device for controlling a web in a printing press, comprising: a supply roll of the web; a printing roll of the press; means for detecting a power loss of the press; and means responsive to the detecting means for controlling the tension of the web in the event of the power loss, including first means for driving the supply roll, and in which the controlling means controls the speed of the driving means, and in which the first driving means controls the rotational speed of the supply roll.
Claim 10
Independent Claim
128 words
A device for controlling a web in a printing press, comprising: a supply roll of the web; a printing roll of the press; means for detecting a power loss of the press; and means responsive to the detecting means for controlling the tension of the web in the event of the power loss, including means for detecting a power loss in the press, first drive means for driving the printing roll, second drive means for driving the supply roll, and in which the controlling means comprises means for selectively connecting the supply roll to the first drive means in the presence of a power loss to the press, and connecting the supply roll to the second drive means in the absence of a power loss to the press.
Claim 11
Independent Claim
128 words
A device for controlling a web in a printing press, comprising: a supply roll of the web; a printing roll of the press; means for detecting a power loss of the press; and means responsive to the detecting means for controlling the tension of the web in the event of the power loss, including means for detecting a power loss in the press, first drive means for driving the printing roll, second drive means for driving the supply roll, and in which the controlling means comprises means for selectively connecting the supply roll to the first drive means in the presence of a power loss to the press, and connecting the supply roll to the second drive means in the absence of a power loss to the press.
Claim 12
Dependent Claim
26 words
The device of claim 8 wherein the controlling means includes a speed changer selectively connected at a desired ratio to the first and second drive means.
Claim 13
Dependent Claim
19 words
