Claims
- 1. An apparatus for stamping labels out of a label material on a supporting web as the web passes the apparatus, said apparatus comprises:
- a rotatable carrier base which is a roller and at least one cutting edge with an apex-line extending in a longitudinal direction of the cutting edge, said cutting edge being provided on and integral with the material of said carrier base roller, said cutting edge having longitudinal sides parallel to the apex-line and a triangular shaped cross section, wherein said triangular cross section has fluted sides with a base that is approximately 0.5 to 1.0 mm wide, said carrier base roller further comprising flat etched areas adjacent the at least one cutting edge, wherein the material of the cutting edge and the carrier base roller are of a unitary construction.
- 2. An apparatus as claimed in claim 1, wherein the height of the edge above the adjacent etched area is approximately 0.4 to 1.0 mm.
- 3. An apparatus as claimed in claim 1, wherein the carrier base roller has a middle cylindrical portion on which the at least one cutting edge is located, and end portions, said end portions having supporting portions thereon; wherein the radius of said end and supporting portions is larger than the radius of the middle portion, which includes the at least one cutting edge, by approximately the thickness of the supporting web.
- 4. An apparatus as claimed in claim 3, wherein the radius of said end and supporting portions is larger than the radius of the middle portion, which includes the at least one cutting edge, by approximately 0.08 to 0.25 mm.
- 5. An apparatus as claimed 1, wherein the at least one cutting edge comprises multiple cutting edges, and wherein the height of said edges extending in the rotating direction is smaller than the height of said edges transverse to the rotating direction except where the extending in the rotating direction edges and transverse edges intersect.
- 6. An apparatus as claimed in claim 1, wherein said carrier base roller is lathe-turned and superficially hardened with a hardness in the range of approximately 35 to 45 HRC.
- 7. An apparatus as claimed in claim 1, wherein the cutting edge has a height that is larger than the thickness of the label material.
- 8. An apparatus as claimed in claim 5, wherein the height of said edges extending in the rotating direction is smaller than the height of said edges transverse to the rotating direction except where the extending in the rotating direction edges and transverse edges intersect.
