Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
100 words
A device for slitting ribbon material of a first width into a plurality of ribbon strips of lesser width comprising, a body member defining a plurality of ribbon receiving passages therethrough, a plurality of blades having cutting edges supported in said body member and traversing said passages so as to provide different numbers of cutting edges in different ones of said passages, whereby ribbon may be slit into various pluralities of ribbin strips of lesser width than the original material by passing the original material through selected ones of said passages, each of said blades traversing more than one passage.
Claim 2
Independent Claim
100 words
A device for slitting ribbon material of a first width into a plurality of ribbon strips of lesser width comprising, a body member defining a plurality of ribbon receiving passages therethrough, a plurality of blades having cutting edges supported in said body member and traversing said passages so as to provide different numbers of cutting edges in different ones of said passages, whereby ribbon may be slit into various pluralities of ribbin strips of lesser width than the original material by passing the original material through selected ones of said passages, each of said blades traversing more than one passage.
Claim 3
Dependent Claim
32 words
The device of claim 1 wherein said housing member has integral partitions defining said passages, and pockets integrally defined in said housing for said blades to position the blades across said passages.
Claim 4
Dependent Claim
30 words
The device of claim 1 wherein said passages are four in number, and three blades are provided, all three of said blades extending across at least two of said passages.
Claim 5
Dependent Claim
39 words
The device of claim 1 wherein said housing member is molded plastic, a plurality of integral partitions extending across said housing and defining said ribbon-receiving passages, and pockets defined in said partitions for positioning said blades across said passages.
Claim 6
Independent Claim
148 words
A device for slitting material in ribbon form comprising a housing member having a front portion and a back portion, said portions cooperating to constitute a closed box having front and back walls, a plurality of parallel partitions integral with one of said portions, each said partition being traversed by a flat passage wide enough to receive a ribbon to be slitted, each partition being provided with at least one slot substantially perpendicular to the plane of the respective partition, and blades having slitting edges positioned in at least two of said slots in adjacent partitions with the slitting edges traversing the passages in said partitions in a position to slit the end of a ribbon-like material as it is passed through one of said passages, said blades presenting different numbers of slitting edges in different ones of said passages with each blade traversing more than one passage.
Claim 7
Independent Claim
148 words
A device for slitting material in ribbon form comprising a housing member having a front portion and a back portion, said portions cooperating to constitute a closed box having front and back walls, a plurality of parallel partitions integral with one of said portions, each said partition being traversed by a flat passage wide enough to receive a ribbon to be slitted, each partition being provided with at least one slot substantially perpendicular to the plane of the respective partition, and blades having slitting edges positioned in at least two of said slots in adjacent partitions with the slitting edges traversing the passages in said partitions in a position to slit the end of a ribbon-like material as it is passed through one of said passages, said blades presenting different numbers of slitting edges in different ones of said passages with each blade traversing more than one passage.
Claim 8
Dependent Claim
28 words
A device according to claim 5 wherein said partitions and passages are four in number and three blades are provided, each blade extending across at least two passages.
Claim 9
Dependent Claim
44 words
A device according to claim 5 wherein the box has end walls and guides are provided on a side surface of a partition and on at least one end wall of the box to receive and support the ends of at least one blade.
