A cutting machine includes an anvil roller rotatable on a machine frame about an axis of rotation. The anvil roller has an anvil surface. A cutting tool is mounted on the machine frame for rotation about an axis of rotation, with a cutter interacting with the anvil surface and with supporting rings which are held on the cutting tool and support it relative to the anvil roller with their supporting ring surfaces and/or vice versa. The quality of the cutting effect can be maintained even when the cutter becomes worn, by enabling the diameter of the supporting ring surface of each supporting ring to be adjustable by radial expansion and contraction.
A cutting machine comprising:
A cutting machine comprising a machine frame, an anvil roller rotatably mounted on the machine frame about a rotary axis and having an anvil surface, a cutting tool mounted on the machine frame for rotation about a rotary axis, with a cutter interacting with the anvil surface and with supporting rings which are held on the cutting tool and support the cutting tool relative to the anvil roller with their supporting ring surfaces and/or vice versa, wherein the diameter at the surface of each supporting ring is adjustable by radial expansion and contraction of the supporting ring by means of a manual mechanical adjustment, to compensate for wear of the cutter by varying the distance of the cutter from the anvil surface.
A cutting tool rotatable about a rotary axis, with a cutter which interacts with an anvil surface of an anvil roller rotatable about a rotary axis, and with supporting rings which extend from and are held to the cutting tool and support it relative to the anvil roller on supporting ring surfaces, wherein for each supporting ring the diameter at the supporting ring surface is adjustable by radial expansion or contraction of the supporting ring by means of an expansion device, in order to change the extension of the supporting rings from the cutting tool with respect to the cutter.
An anvil roller rotatable about a rotary axis, comprising an anvil surface which interacts with a cutter of a cutting tool rotatable about a rotary axis, and further comprising supporting rings which are held to the anvil roller and support it relative to the cutting tool on supporting ring surfaces, wherein for each supporting ring the diameter at the supporting ring surface is adjustable by radial expansion or contraction of the supporting ring by means of an expansion device, in order to change the extension of the supporting rings from the anvil surface.

The present disclosure relates to the subject matter disclosed in German application No. 100 40 024.8 of Aug. 16, 2000, which is incorporated herein by reference in its entirety and for all purposes.
The invention relates to a cutting machine comprising a machine frame, an anvil roller rotatably mounted on the machine frame about a rotary axis and having an anvil surface, a cutting tool mounted on the machine frame for rotation about a rotary axis, with a cutter interacting with the anvil surface and with supporting rings which are held on the cutting tool and support it relative to the anvil roller with their supporting ring surfaces and/or vice versa.
A cutting machine of this type is known e.g. from German patent application 198 34 104.0.
FIG. 1 is a vertical section through a cutting machine according to the invention taken along line 1—1 in FIG. 2;
FIG. 2 is a vertical section taken along line 2—2 in FIG. 1;
FIG. 3 is a larger-scale representation of the anvil roller and cutting tool in FIG. 2;
A cutting machine according to the invention, shown in respective sections in FIGS. 1 and 2, comprises a machine frame referred to generally as 10 and having two spaced bearing members 12 and 14.
Each bearing member, e.g. member 12 in FIG. 1, comprises two side mounts 16 and 18 with a lower bearing mount 20 and an upper bearing mount 22 arranged between them.
The lower bearing mount 20 is on the one hand located between the side mounts 16 and 18 and on the other hand seated securely on a base plate 24 of the machine frame 10. The mount 20 has a bearing receiver 26 in which the outer race 30 of a lower pivot bearing referred to generally as 28 is inserted, the outer peripheral side of the race 30 lying against an internal surface of the receiver 26. The race 30 is fixed in the receiver 26 by an external retaining member 32 and an internal retaining member 34; these have retaining rings 36 and 38 which lie against lateral annular surfaces of the external race 30 and thus fix it in the receiver 26. In addition the external retaining member 32 has a cover 40.
