Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
117 words
Device for cutting a web in a printer, comprising: a stationary bar having two surfaces intersecting at right angles to establish a cutting edge extending transversely to a direction of web advance in the printer; one of the surfaces engaging the web to be cut; carriage means running along but above said bar; a cutting roll journalled on the carriage having first and second cylindrical portions respectively of small and large diameter and annular shoulder in between; means for urging the roll down towards the one surface of this bar so that the shoulder is located adjacent to the other one of the bar surfaces; and means for urging the shoulder laterally against the other bar surface.
Claim 2
Dependent Claim
117 words
Device for cutting a web in a printer, comprising: a stationary bar having two surfaces intersecting at right angles to establish a cutting edge extending transversely to a direction of web advance in the printer; one of the surfaces engaging the web to be cut; carriage means running along but above said bar; a cutting roll journalled on the carriage having first and second cylindrical portions respectively of small and large diameter and annular shoulder in between; means for urging the roll down towards the one surface of this bar so that the shoulder is located adjacent to the other one of the bar surfaces; and means for urging the shoulder laterally against the other bar surface.
Claim 3
Dependent Claim
20 words
Device as in claim 1, the large and small diameters of the roll having a ratio of 1:1.1 to 1:1.6.
Claim 4
Dependent Claim
20 words
Device as in claim 1, including means on the carriage for retracting the roll up and away from the bar
Claim 5
Dependent Claim
18 words
Device as in claim 3, including stationary means for operating the retracting means upon passing of the carriage.
Claim 6
Dependent Claim
16 words
Device as in claim 4, including means for latching the retracting means into a non-cutting position.
Claim 7
Dependent Claim
94 words
Device for cutting a web in a printer comprising: a stationary bar having a cutting edge, extending transversely to a direction of web advance in a printer; a carriage running along said bar; an axially displaceable pivot lever on the carriage; a stepped cutting roll journalled on the pivot lever; means for urging the stepped roll against the edge for cutting by tearing as the roll moves across the bar in rolling engagement therewith; and means for pivoting and axially displacing said lever to move the roll from a cutting position to non-cutting positions.
Claim 8
Dependent Claim
94 words
Device for cutting a web in a printer comprising: a stationary bar having a cutting edge, extending transversely to a direction of web advance in a printer; a carriage running along said bar; an axially displaceable pivot lever on the carriage; a stepped cutting roll journalled on the pivot lever; means for urging the stepped roll against the edge for cutting by tearing as the roll moves across the bar in rolling engagement therewith; and means for pivoting and axially displacing said lever to move the roll from a cutting position to non-cutting positions.
