Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
68 words
A device for supplying strip-like fabric, including at least three rigid rollers, at least one of said rigid rollers being adapted to be driven, and an additional roller, characterized in that said rigid rollers are mounted about the additional roller, all said rigid rollers being rotatable in the same direction of rotation, and said additional roller being resiliently distortable, presses against the rigid rollers and is distorted thereby.
Claim 2
Independent Claim
68 words
A device for supplying strip-like fabric, including at least three rigid rollers, at least one of said rigid rollers being adapted to be driven, and an additional roller, characterized in that said rigid rollers are mounted about the additional roller, all said rigid rollers being rotatable in the same direction of rotation, and said additional roller being resiliently distortable, presses against the rigid rollers and is distorted thereby.
Claim 3
Dependent Claim
21 words
The device according to claim 1, characterized in that at least one endless taut strip is wound around the rigid rollers.
Claim 4
Dependent Claim
39 words
The device according to claim 1, characterized in that each of the rigid rollers adjoins locally fixed support rollers at that point which is facing in the direction of stress exerted by the strip-like fabric on said rigid roller.
Claim 5
Independent Claim
60 words
A device for supplying strip-like fabric, including rigid rollers, at Least one of said rigid rollers being adapted to be driven, and one flexible roller, characterized in that at least three rigid rollers are housed around said one flexible roller, said flexible roller pressing against the rigid rollers, and the flexible roller being formed from a tube filled with fluid.
Claim 6
Independent Claim
60 words
A device for supplying strip-like fabric, including rigid rollers, at Least one of said rigid rollers being adapted to be driven, and one flexible roller, characterized in that at least three rigid rollers are housed around said one flexible roller, said flexible roller pressing against the rigid rollers, and the flexible roller being formed from a tube filled with fluid.
Claim 7
Dependent Claim
14 words
The device according to claim 4, characterized in that the fluid is compressed air.
Claim 8
Dependent Claim
72 words
The device according to claim 4 in which supporting rollers are provided against one of the rigid rollers on a side of said rigid roller which faces in the direction of pull exercised by the strip-like fabric on said rigid roller, at least one endles taut strip being wound around the rigid rollers, characterized in that a supporting roller system is enclosed between two of the rigid rollers and the endless strip.
Claim 9
Independent Claim
102 words
A device for supplying strip-like fabric, including rigid rollers, at least one of said rigid rollers being adapted to be driven, and one flexible roller, at least three rigid rollers being housed around said one flexible roller, and said flexible roller pressing against the rigid roller, characterized in that a roller unit comprising said rigid rollers and said flexible roller is positioned in front of a drawing roller unit for the strip-like fabric and is rotatably housed around the axis of a rigid roller which is adapted to be driven, said unit cooperating with a signal transmitter linked with an adjustable drive.
Claim 10
Independent Claim
102 words
A device for supplying strip-like fabric, including rigid rollers, at least one of said rigid rollers being adapted to be driven, and one flexible roller, at least three rigid rollers being housed around said one flexible roller, and said flexible roller pressing against the rigid roller, characterized in that a roller unit comprising said rigid rollers and said flexible roller is positioned in front of a drawing roller unit for the strip-like fabric and is rotatably housed around the axis of a rigid roller which is adapted to be driven, said unit cooperating with a signal transmitter linked with an adjustable drive.
Claim 11
Independent Claim
74 words
A device for supplying strip-like fabric, including rigid rollers, at least one of said rigid rollers being adapted to be driven, and one flexible roller, at least three rigid rollers being housed around said one flexible roller, and said flexible roller pressing against the rigid rollers, characterized in that stationary supporting rollers are provided against the rigid rollers on the connecting line of the center points of the flexible roller and the rigid rollers.
Claim 12
Independent Claim
74 words
A device for supplying strip-like fabric, including rigid rollers, at least one of said rigid rollers being adapted to be driven, and one flexible roller, at least three rigid rollers being housed around said one flexible roller, and said flexible roller pressing against the rigid rollers, characterized in that stationary supporting rollers are provided against the rigid rollers on the connecting line of the center points of the flexible roller and the rigid rollers.
