Abstract
A mandrel is utilized to support a roll of material. The mandrel includes a retaining element, which can be placed on an inner circumference of a roll of material, and at least one carrier element which transmits a torque between the mandrel and the material roll. The carrier element can be engaged with the roll of material in a non-positive manner.
Claims24
A mandrel assembly adapted to transmit torque to an object to be driven, said mandrel assembly comprising:
- a mandrel adapted to seat an object to be driven;
- an engagement element arranged in said mandrel;
- a cutting edge on said engagement element;
- first and second cutting faces on said engagement element and intersecting each other to define said cutting edge on said engagement element;
- a wedge angle formed by said first and second intersecting cutting faces;
- and
- a longitudinal direction of said engagement element, said wedge angle increasing along said cutting edge in said longitudinal direction in which said engagement element penetrates into an object to be driven.
A mandrel assembly adapted to transmit torque to an object to be driven, said mandrel assembly comprising:
- a mandrel adapted to seat an object to be driven;
- an engagement element arranged in said mandrel;
- a cutting edge on said engagement element;
- first and second cutting faces on said engagement element and intersecting each other to define said engagement cutting edge on said engagement element;
- and
- a wedge angle formed by said cutting faces, said engagement element being adapted to penetrate into an object to be driven, said cutting faces each having a convex shape.
A mandrel assembly adapted to seat a roll of material comprising:
- a receiver element engagable with an inner circumference of said roll of material;
- an engagement element adapted to transmit a torque between said mandrel assembly and said roll of material;
- a cutting edge on said engagement element;
- a switching arrangement adapted to strip said roll of material off said engagement element, said engagement element passing through said switching element;
- means for displacing said switching arrangement in an axial direction of said roll of material between an ejection position and a clamped position;
- an electrical drive mechanism including a rotor, said receiver element, said engagement element and said switching arrangement being arranged coaxially in relation to said rotor of said electrical drive mechanism;
- and
- an end face of said roll of material, said engagement element adapted to positively engage said end face of said roll of material.
